wpf virtualizingstackpanel different behavior on different Win10 machines - c#

My WPF application is using VirtualizingStackPanel for ListView. Scrolling this list is working fine on two different machines: my host machine (Windows 10 v1803 build 17134.228) and one virtual machine (Windows 10 v1607 build 14393.2312 ). If I run the same application, exact the same copy, on my other VM (Windows 10 v1803 build 17134.165), the list doesn’t scroll smooth – it’s very slow. Short scroll steps about couple of lines is fine (CacheLength), but scrolling over more lines is very bad, most like virtualizing is not properly working.
Anybody knows, if virtualizing depends on any component or settings of windows 10 system?
Just pasting a part of code with ListView.
Thanks for help.
Update: sorry for disinformation - scrolling is not slow, the scroll unit is not an Item but whole Page (maybe more then page). So visual effect of scrolling is bad.

Binding DataGridTemplateColumn in UserControl.Resources

I am currently trying to write a small calendar program in C# WPF.
For the datagrid I have written a userControl.
This works like I want it to work. I will still need to update the optics but for now it is good.
The problem is the code of the DataGridTextColums.. It is all redundant.
So if I want to change something I need to change it everywhere.

<!--same for wednesdayCell to sundayCell-->
</DataGrid.Columns>
</DataGrid>
So as you can see each DataGridTemplateColumn binds to a different Cell (Monday to Sunday).
I tried to create a template out of this. If i keep "MondayCell" in the template (like in the Code below), it works. But obviously I cannot use any other source of data except "MondayCell" then.
See:
<UserControl.Resources>
<DataTemplate x:Key="MyCellTemplate">

Usage in the Datagrid: This works, but only shows the data from MondayCell.
<DataGridTemplateColumn Header="MO" Width="*" IsReadOnly="True">
<DataGridTemplateColumn.CellTemplate>
<StaticResource ResourceKey="MyCellTemplate"/>
</DataGridTemplateColumn.CellTemplate>
<DataGridTemplateColumn.CellStyle>
<StaticResource ResourceKey="MyCellStyle"/>
</DataGridTemplateColumn.CellStyle>
</DataGridTemplateColumn>
How I want to use it, but doesn't work like this:
Any help is appreciated.
For now I keep it redundant, but I would rather use a template so I only need to change 1 piece of code instead of 7.
Thank you for your help!
I would like to present a solution that is based on using a UserControl:
<DataGridTemplateColumn >
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<local:StandardColumn Column="{Binding MondayCell}"/>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
<DataGridTemplateColumn >
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<local:StandardColumn Column="{Binding TuesdayCell}"/>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
The StandardColumn implementation , for simplicity , can be as following:
<UserControl x:Class="Problem8.StandardColumn"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:local="clr-namespace:Problem8"
mc:Ignorable="d"
d:DesignHeight="450" d:DesignWidth="800" Name="Parent">
<StackPanel>
<TextBlock Text="{Binding ElementName=Parent,Path=Column}"/>
</StackPanel>
</UserControl>
In this userControl we have a dependency property called Column :
public partial class StandardColumn : UserControl
{
public StandardColumn()
{
InitializeComponent();
}
public static readonly DependencyProperty ColumnProperty =
DependencyProperty.Register("Column", typeof(object), typeof(StandardColumn));
public object Column
{
get { return (object)GetValue(ColumnProperty); }
set { SetValue(ColumnProperty, value); }
}
}
We can also make it even more simple by using the DataContext instead of the Column dependency property.
You could build your columns dynamically using a base string out a txt file and use xamlreader.Parse or persist to disk and then use xamlreader.load.
I answered a similar question a while back but I cannot find the answer.
Create a template as a txt file with placeholders for the parts you want to substitute. Here is the example I use in a sample I wrote:
<?xml version="1.0" encoding="utf-8" ?>
<DataGridTemplateColumn>
<DataGridTemplateColumn.Header>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<TextBlock Text="xxMMMxx" TextAlignment="Center" Grid.ColumnSpan="2"/>
<TextBlock Text="Units" Margin="2,0,2,0" Grid.Row="1"/>
<TextBlock Text="Value" Margin="2,0,2,0" Grid.Row="1" Grid.Column="2" />
</Grid>
</DataGridTemplateColumn.Header>
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<TextBlock Text="{Binding MonthTotals[xxNumxx].Products}" Margin="2,0,2,0" TextAlignment="Right"/>
<TextBlock Text="{Binding MonthTotals[xxNumxx].Total}" Margin="2,0,2,0" TextAlignment="Right" Grid.Column="1"/>
</Grid>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
Make that content, copy if newer and you will get a txt file next to your exe you can read in.
In this I have a dynamic datagrid as another txt file as well, but that is not totally necessary.
Here's my code builds and adds columns.
You could just work with the txt file as a string and do string substitution. This shows manipulating it as xml which has the potential for you to insert xelements etc. It is setting attributes whilst you can maybe forget that part and just do the string substitution, xamlreader.parse into a datagrid column and add to the columns collection.
It is substituting month numbers in the binding for a range of months.
If you consider a rolling last n month financial report, this is the general idea. Last month would be 3 now in april. 4 when you run in may.
private void Button_Click(object sender, RoutedEventArgs e)
{
// Get the datagrid shell
XElement xdg = GetXElement(#"pack://application:,,,/dg.txt");
XElement cols = xdg.Descendants().First(); // Column list
// Get the column template
XElement col = GetXElement(#"pack://application:,,,/col.txt");
DateTime mnth = DateTime.Now.AddMonths(-6);
for (int i = 0; i < 6; i++)
{
DateTime dat = mnth.AddMonths(i);
XElement el = new XElement(col);
// Month in mmm format in header
var mnthEl = el.Descendants("TextBlock")
.Single(x => x.Attribute("Text").Value.ToString() == "xxMMMxx");
mnthEl.SetAttributeValue("Text", dat.ToString("MMM"));
string monthNo = dat.AddMonths(-1).Month.ToString();
// Month as index for the product
var prodEl = el.Descendants("TextBlock")
.Single(x => x.Attribute("Text").Value == "{Binding MonthTotals[xxNumxx].Products}");
prodEl.SetAttributeValue("Text",
"{Binding MonthTotals[" + monthNo + "].Products}");
// Month as index for the total
var prodTot = el.Descendants("TextBlock")
.Single(x => x.Attribute("Text").Value == "{Binding MonthTotals[xxNumxx].Total}");
prodTot.SetAttributeValue("Text",
"{Binding MonthTotals[" + monthNo + "].Total}");
cols.Add(el);
}
string dgString = xdg.ToString();
ParserContext context = new ParserContext();
context.XmlnsDictionary.Add("", "http://schemas.microsoft.com/winfx/2006/xaml/presentation");
context.XmlnsDictionary.Add("x", "http://schemas.microsoft.com/winfx/2006/xaml");
DataGrid dg = (DataGrid)XamlReader.Parse(dgString, context);
Root.Children.Add(dg);
}
private XElement GetXElement(string uri)
{
XDocument xmlDoc = new XDocument();
var xmltxt = Application.GetContentStream(new Uri(uri));
string elfull = new StreamReader(xmltxt.Stream).ReadToEnd();
xmlDoc = XDocument.Parse(elfull);
return xmlDoc.Root;
}
}
You could potentially build out your entire year view using this sort of approach. Build it as xml or a string. Save to disk. xamlreader.load() it back in as controls off disk.
A similar string manipulation based approach would be to build your control as text. Save as a datatemplate in a resource dictionary. You can load such an uncompiled resource dictionary off disk then and just build once a year. You could build centrally in a small utility app intended just for the purpose and distribute to clients.
This is my second solution. I believe that the selection of the DataGrid as a base have created this complexity. Alternatively we can consider more basic controls.
I am drafting the solution:
The MonthView user control may look as following:
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<local:HeaderView Grid.Row="0"/>
<ItemsControl ItemsSource="{Binding Weeks}" Grid.Row="1" >
<ItemsControl.ItemTemplate>
<DataTemplate>
<local:WeekView/>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</Grid>
The WeekView user control may look as following:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<local:DayView DataContext="{Binding CwCell}" Grid.Column="0"/>
<local:DayView DataContext="{Binding MondayCell}" Grid.Column="1"/>
<local:DayView DataContext="{Binding TuesdayCell}" Grid.Column="2"/>
<local:DayView DataContext="{Binding WednesdayCell}" Grid.Column="3"/>
<local:DayView DataContext="{Binding ThursdayCell}" Grid.Column="4"/>
<local:DayView DataContext="{Binding FridayCell}" Grid.Column="5"/>
<local:DayView DataContext="{Binding FridayCell}" Grid.Column="6"/>
<local:DayView DataContext="{Binding SaturdayCell}" Grid.Column="7"/>
<local:DayView DataContext="{Binding SundayCell}" Grid.Column="8"/>
</Grid>
The DayView user control may look as following:
<Border BorderBrush="Black" BorderThickness="1">
<TextBlock Text="{Binding Text}" Width="20" Height="20" VerticalAlignment="Center" HorizontalAlignment="Center"/>
</Border>
The HeaderView user control may look as following:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<local:ColumnHeaderView DataContext="CW" Grid.Column="0" />
<local:ColumnHeaderView DataContext="MO" Grid.Column="1" />
<local:ColumnHeaderView DataContext="TU" Grid.Column="2" />
<local:ColumnHeaderView DataContext="WE" Grid.Column="3" />
<local:ColumnHeaderView DataContext="TH" Grid.Column="4" />
<local:ColumnHeaderView DataContext="FR" Grid.Column="5" />
<local:ColumnHeaderView DataContext="SA" Grid.Column="6" />
<local:ColumnHeaderView DataContext="SU" Grid.Column="7" />
</Grid>
The ColumnHeaderView user control may look as following:
<Border BorderBrush="Black" BorderThickness="1">
<TextBlock Text="{Binding }" Width="20" Height="15" VerticalAlignment="Center" HorizontalAlignment="Center"/>
</Border>

GridSplitter getting stuck after dragging some pixels

GridSplitter getting stuck after dragging some pixels,and have to reselect the splitter and drag again.
I am using RadTreeView in one column, and ListBox in second column, in which user can select Item from ListBox and Drag it into RadTreeView.
Please find below screenshot for the UI.
I tried to find solution on SO, but not getting any useful answer.
Please find below code for the same, Let me know if you require more information for the same.

Making a portion of a TreeViewItem wrap

I have a TreeViewItem that has multiple parts in it -- an icon, a header, and a piece of data. I'm trying to get the last part to wrap without making everything wrap, and I'm having no luck. Here's an illustration of the problem:
I've tried a few things that I've found on Stack Overflow, with no luck. There were three suggestions I found:
Put the item in a grid with a column with bound to the TreeView's actual width. This is implemented in the XAML below, but doesn't seem to help.
Disable horizontal scrolling on the TreeView with ScrollViewer.HorizontalScrollBarVisibility = "Disabled", which I also implemented in the XAML below.
Wrap what I need in a WrapPanel. I tried this, but got poor results. When I wrapped the whole TreeViewItem in one, I got wrapping that was hard to control (the whole item wraps, so all parts wrapped and it looked awful). When I wrapped just the desired TextBlock in one, I got no results at all. So I took it out.
Here's the template I have for the TreeViewItem:
<DataTemplate x:Key="BasicPropertyTemplate" DataType="{x:Type json:JProperty}">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="{Binding RelativeSource={RelativeSource AncestorType=TreeView}, Path=ActualWidth}" />
</Grid.ColumnDefinitions>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="16" />
<ColumnDefinition Width="3" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="3" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="3" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<Border
Width="12"
Height="12"
HorizontalAlignment="Center"
VerticalAlignment="Center"
Background="{Binding Converter={StaticResource TypeToColorConverter}, ConverterParameter='Interior'}"
BorderBrush="{Binding Converter={StaticResource TypeToColorConverter}}"
BorderThickness="1" />
<TextBlock Grid.Column="2" Text="{Binding Name, Mode=OneWay}" />
<TextBlock Grid.Column="4" Text=": " />
<TextBlock
Grid.Column="6"
Text="{Binding Value, Converter={StaticResource StringFormatConverter}, Mode=OneWay}"
TextWrapping="Wrap" />
</Grid>
</Grid>
</DataTemplate>
Here's an illustration of the layout, so you can see how the TreeViewItem is composed:
Essentially, the gray part is the icon, the green parts are just spacers between items, the blue parts are header and a colon (essentially irrelevant to what this question is about), and the red part is the actual content.
It's the red part I want to wrap.
Here's the TreeView definition:
<TreeView
x:Name="JsonRoot"
Grid.Column="0"
ItemTemplateSelector="{StaticResource TreeViewTemplateSelector}"
Loaded="JsonRoot_Loaded"
ScrollViewer.HorizontalScrollBarVisibility="Disabled"
VirtualizingStackPanel.IsVirtualizing="True" />
I feel like I'm doing something simple wrong, but I'm not sure what. Is there a way to accomplish this without just locking the TextBlock width to something arbitrary, like 200?
My investigation showed that TextBlock Wrap doesn't work with <ColumnDefinition Width="Auto"/>. So I changed last <ColumnDefinition Width="Auto"/> in DataTemplate to <ColumnDefinition Width="*"/>.
Unfortunately TreeViewItem (which is a default container for TreeView items) has <ColumnDefinition Width="Auto"/> in its Template and places our items there. I have tried to make a custom template with <ColumnDefinition Width="*"/> and it worked but code is really long. So I decided to compensate the effect by binding Grid width:
<DataTemplate x:Key="BasicPropertyTemplate" DataType="{x:Type json:JProperty}">
<Grid Width="{Binding RelativeSource={RelativeSource AncestorType=TreeViewItem}, Path=ActualWidth}" >
<Grid Margin="0,0,20,0"> <!--right margin to compensate excessive width-->
<Grid.ColumnDefinitions>
<ColumnDefinition Width="16" />
<ColumnDefinition Width="3" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="3" />
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="3" />
<ColumnDefinition Width="*"/> <!--was Auto-->
</Grid.ColumnDefinitions>
<Border
Width="12"
Height="12"
HorizontalAlignment="Center"
VerticalAlignment="Center"
Background="{Binding Converter={StaticResource TypeToColorConverter}, ConverterParameter='Interior'}"
BorderBrush="{Binding Converter={StaticResource TypeToColorConverter}}"
BorderThickness="1" />
<TextBlock Grid.Column="2" Text="{Binding Name, Mode=OneWay}" />
<TextBlock Grid.Column="4" Text=": " />
<TextBlock
Grid.Column="6"
Text="{Binding Value, Converter={StaticResource StringFormatConverter}, Mode=OneWay}"
TextWrapping="Wrap" />
</Grid>
</Grid>
</DataTemplate>
ScrollViewer.HorizontalScrollBarVisibility="Disabled" is important element and should be set.
Try changing the grid in DataTemplate with a DockPanel:
<DataTemplate>
<DockPanel>
<Border Width="12"
Height="12"
HorizontalAlignment="Center"
VerticalAlignment="Center"
Background="{Binding Converter={StaticResource TypeToColorConverter}, ConverterParameter='Interior'}"
BorderBrush="{Binding Converter={StaticResource TypeToColorConverter}}"
BorderThickness="1" />
<TextBlock Text="{Binding Name, Mode=OneWay}" />
<TextBlock Text=": " />
<TextBlock Text="{Binding Value, Converter={StaticResource StringFormatConverter}, Mode=OneWay}"
TextWrapping="Wrap" />
</DockPanel>
</DataTemplate>

Complete DataTemplate clickable?

I have following DataTemplate for usage within my phone.LongListSelector in my XAML view:
<DataTemplate x:Name="myLocationsListTemplate">
<StackPanel Margin="0,0,0,15">
<Grid VerticalAlignment="Top" Margin="0,0,5,0">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="120" />
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" TextTrimming="WordEllipsis" Text="{Binding Name}" TextWrapping="NoWrap" Style="{StaticResource PhoneTextLargeStyle}" VerticalAlignment="Top" Margin="0,0,0,22" />
<Image Grid.Column="0" Width="138" Height="25" Source="/mAppData/stars-3.png" HorizontalAlignment="Left" VerticalAlignment="Bottom" Margin="0"/>
<TextBlock Grid.Column="1" Text="{Binding DistanceInMeterFormatted, FallbackValue=fallback, TargetNullValue=nullvalue, Mode=OneWay}" TextWrapping="NoWrap" Style="{StaticResource PhoneTextSubtleStyle}" HorizontalAlignment="Right" Margin="0,0,-3,20" VerticalAlignment="Bottom"/>
<TextBlock Grid.Column="1" Text="vor 10 min." TextWrapping="NoWrap" Margin="0" Style="{StaticResource PhoneTextSubtleStyle}" HorizontalAlignment="Right" VerticalAlignment="Bottom"/>
</Grid>
<Grid VerticalAlignment="Top" Margin="0,10,0,0">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Image Grid.Column="0" Width="100" Height="100" Source="{Binding PreviewImg1}"/>
<Image Grid.Column="1" Width="100" Height="100" Source="{Binding PreviewImg2}"/>
<Image Grid.Column="2" Width="100" Height="100" Source="{Binding PreviewImg3}"/>
<Image Grid.Column="3" Width="100" Height="100" Source="{Binding PreviewImg4}"/>
</Grid>
</StackPanel>
</DataTemplate>
Now I want the complete DataTemplate Content made "clickable". Means: If user clicks on a TextBlock or one of the four Images or on whatever displayed in die List, an action should be performed with a databound property (saying the Name from the bound data should be given).
Any ideas how to get this working?
Why don't you just stick your entire template into a button? You can style the button if needs be to remove any default appearance you don't like. eg.
<Style x:Key="BlankButtonStyle" TargetType="ButtonBase">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ButtonBase">
<ContentPresenter />
</ControlTemplate>
</Setter.Value>
</Setter>
<Setter Property="Background" Value="Transparent" />
</Style>

Putting status bar information into a MessageBox popup in WPF

So i'm comletely new to WPF and C# and have been tasked to take the existing information we have in a status bar of our MainWindow.xaml and put it in a popup, like a MessageBox. I'm not really sure how to do that as I can see some of the code that generates the text, and the values for the progress bar in code, but I don't see how those individual methods get bound to the .xaml file. Here's what's in the current xaml. Any guidance would be appreciated. Thanks.
<StatusBar Width="Auto" MaxHeight="50" Grid.Row="2" HorizontalAlignment="Stretch">
<StatusBar.ItemsPanel>
<ItemsPanelTemplate>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition MinWidth="100" Width="Auto"/>
<ColumnDefinition MinWidth="100" Width="Auto"/>
<ColumnDefinition MinWidth="300"/>
</Grid.ColumnDefinitions>
</Grid>
</ItemsPanelTemplate>
</StatusBar.ItemsPanel>
<StatusBarItem Grid.Column="0">
<TextBlock Name="tbxProgressText" Text="{Binding Path=ProgressText, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"/>
</StatusBarItem>
<StatusBarItem Grid.Column="1">
<TextBlock Name="tbxProgressText2" Text="{Binding Path=ProgressText2, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"/>
</StatusBarItem>
<StatusBarItem Grid.Column="2">
<ProgressBar Width="300" Height="18" Name="ProgressBar"
Value="{Binding Path=PbarValue, Mode=OneWay}"
Minimum="{Binding Min}" Maximum="{Binding Maximum}"/>
</StatusBarItem>
</StatusBar>
You could start with something like this (untested and unstyled):
<Popup Width="Auto" MaxHeight="50" Grid.Row="2" HorizontalAlignment="Stretch" IsOpen="true">
<StackPanel>
<TextBlock Name="tbxProgressText" Text="{Binding Path=ProgressText, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"/>
<TextBlock Name="tbxProgressText2" Text="{Binding Path=ProgressText2, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"/>
<ProgressBar Width="300" Height="18" Name="ProgressBar"
Value="{Binding Path=PbarValue, Mode=OneWay}"
Minimum="{Binding Min}" Maximum="{Binding Maximum}"/>
</StackPanel>
</Popup>
This popup will be always open because of the property IsOpen="true" and it will be placed where the statusbar is placed in the current application. You could start by fixing those things and then try to add some styles to the content of the popup.
Hope it helps!
