Hi I Need To Generate A Table In My Metro APP BUT I GET WRONG OUTPUT PLEASE HELP I BIND HEADER AND CONTENTS SEPERATELY USING LIST
C# CODE
foreach (var item in itemsreceiveds)

}
var groupedPersons = variable2.Select((emp) => new { sectionName = emp.headers }).ToList().Distinct();
foreach (var s in groupedPersons)
{
firstheader = s.sectionName;
string[] sepword = firstheader.Split('#');
firstheader = sepword[0].ToUpper();
secondheader = sepword[1].ToUpper();
thirdheader = sepword[2].ToUpper();
variableheader.Add(new contentdataheader(firstheader,secondheader,thirdheader));
groupListView.ItemsSource = variableheader;

I Get Ouput As
But I Need Output As This
Here's the simplest answer - a working demo.
I didn't do everything for you, mate, but I sure did a lot. You'll have to code a little to get it just how you like. If you are using a custom control suite, most of this might be done for you. If not, this will get you down the road. Far down the road.
Take this code behind:
public sealed partial class MainPage : Page
{
public MainPage()
{
this.InitializeComponent();
}
}
public class Datum
{
public DateTime Date { get; set; }
public string Year { get { return Date.ToString("yyy"); } }
public string Month { get { return Date.ToString("MMMM"); } }
public string Day { get { return Date.ToString("dd"); } }
public string Weekday { get { return Date.ToString("dddd"); } }
}
public class ViewModel
{
public ViewModel()
{
// data
var _Data = Enumerable.Range(1, 20)
.Select(x => new Datum { Date = DateTime.Now.Add(TimeSpan.FromDays(x * 14)) });
Data = new ObservableCollection<Datum>(_Data);
}
public ObservableCollection<Datum> Data { get; private set; }
}
And then try this XAML:
<Page.DataContext>
<local:ViewModel/>
</Page.DataContext>
<Grid Background="{StaticResource ApplicationPageBackgroundThemeBrush}">
<StackPanel>

You should get something like this:
To add to Jerry's XAML in his answer. You can replace the ItemsControl with a ListBox (same template/itemTemplate modifications) to get the same view, but also the ability to use SelectedIndex, but I don't know if that applies to this question.
Note: I did find you need to add a Width to the ListBox. You can't just let the Grid in the ItemTemplate do it.
Maybe you're looking for something like this.
XAML:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="150" />
<ColumnDefinition Width="150" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="30" />
<RowDefinition />
</Grid.RowDefinitions>
<Rectangle Fill="Black" Grid.ColumnSpan="2" Grid.Row="0" />
<TextBlock Text="Integer" VerticalAlignment="Center" HorizontalAlignment="Left" Margin="5" Grid.Row="0" Grid.Column="0" FontSize="14" />
<TextBlock Text="String" VerticalAlignment="Center" HorizontalAlignment="Left" Margin="5" Grid.Row="0" Grid.Column="1" FontSize="14" />
<ListView x:Name="ListViewDisplay" ItemsSource="{Binding}" Grid.Row="1" Grid.ColumnSpan="2" BorderThickness="1" BorderBrush="Black" Background="White" RequestedTheme="Light">
<ListView.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="150" />
<ColumnDefinition Width="150" />
</Grid.ColumnDefinitions>
<TextBlock Text="{Binding Integer}" Margin="5" Grid.Column="0" FontSize="14" />
<TextBlock Text="{Binding String}" Margin="5" Grid.Column="1" FontSize="14" />
</Grid>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</Grid>
Behind code:
public sealed partial class SamplePage : Page
{
ObservableCollection<ROWS> r = new ObservableCollection<ROWS>();
public SamplePage()
{
this.InitializeComponent();
r.Add(new ROWS { Integer = 1, String = "ONE" });
r.Add(new ROWS { Integer = 2, String = "TWO" });
r.Add(new ROWS { Integer = 3, String = "THREE" });
r.Add(new ROWS { Integer = 4, String = "FOUR" });
r.Add(new ROWS { Integer = 5, String = "FIVE" });
ListViewDisplay.ItemsSource = r;
}
}
public class ROWS {
public int Integer { get; set; }
public string String { get; set; }

I'm working on a UWP FTP front-end application. I've created a UserControl that mimics the form of a standard Windows desktop icon (consisting of a StackPanel containing an Image and a TextBlock) which is to be used as a way of displaying saved favorites. What I'd like is for the user to be able to select any image to be used as the icon for each favorite, but have run into some pretty significant issue with getting this to work, I believe due to the Windows 10 "no access to filesystem" restriction--I haven't figured out that part yet.
As a temporary substitution, I came up with the idea of having a set of icons for the user to select from, all stored within the Assets folder of the application. I've created an IconSelector page/child window (IconSelector.xaml) that pops up when appropriate, allowing the user to select from 8 different Images.
The issue I'm running into is getting the selected Image back to the parent window (MainPage.xaml). I thought of just passing an int from child to parent, and then use that int with an enum to indicate the correct image, but I can't figure out how to pass any parameter at all between child and parent.
I did find this question on SO, but it's for Silverlighbt and doesn't seem to work in UWP (unless I implemented it incorrectly).
Does anybody have any idea on how to accomplish this? Code (relevant portions) pasted below:

namespace FtpSharp

public sealed partial class IconSelector : Page
{
private static readonly DependencyProperty SelectedIconProperty = DependencyProperty.Register("SelectedIcon", typeof(int),
typeof(IconSelector), new PropertyMetadata(0));

tappedBorder.BorderBrush = new SolidColorBrush(Color.FromArgb(255,0,0,255));
}
}
In this case you can either provide the result as a public property of the IconSelector class, or as EventArgs of an event. You already have the SelectedIcon property there, so you can use it. To notify the MainPage that the selection has occurred, you need to add an event to IconSelector - for example DialogCompleted:
public event EventHandler<int> DialogCompleted;
You will trigger this event when the dialog is confirmed by the user:
DialogCompleted?.Invoke(this, SelectedIcon);
Then within MainPage, you need to subscribe to this event:
IconSelector selector = new IconSelector();
selector.DialogCompleted += IconDialogCompleted;
ShowDialog(selector);
And now get the SelectedIcon inside the handler:
private void IconDialogCompleted(object sender, int selectedIcon)
{
//do something with selectedIcon
}
Overview
I'm trying to create a custom expander which contains a visual tree where the user can select or deselect nodes. But the tree is not important for now. Important is the header which I had to overwrite so I can show all the information the user needs.
Issue
Somehow the Binding of the textboxes inside the DataTemplate doesn't work at all. No matter what I enter into the fields are always empty and the setter of the DependencyProperty doesn't get called.

But I always get the Fallback Values. Does anybody know why this happens? Do I have to link the DataTemplate to the Control Class or something?
Solution (Thanks to mm8)
For every binding in the DataTemplate refer to the parent UserControl
<Textbox
...
Text={Binding Path=XY, RelativeSource={RelativeSource AncestorType=UserControl}, FallbackValue=...}"
... />
Try to bind to the Header property of the parent UserControl using a {RelativeSource}:
<TextBlock Grid.Column="1"
Margin="2"
Text="{Binding Path=Header, RelativeSource={RelativeSource AncestorType=UserControl}, FallbackValue=Header}"
Foreground="Black"
FontWeight="Bold"
FontSize="14"
/>
I'm trying to create a 'spreadsheet like' grid with column headers showing information from a set of player objects with the cell contents maximised in size. To do this I have a UWP app with a ListView bound to the collection of Player objects. The ListView.ItemsPanel uses a UniformGridPanel obtained from here
The UniformGridPanel has a Rows property bound to the player count which can vary, and one Column. The UniformGridPanel is used to show ALL players, giving each player item equal height, so no player is partially displayed and there is no scrolling. The UniformGridPanel is working fine.
The ListView.ItemTemplate is a Gridof a fixed number of columns representing data about each player.
My problems are:
The info in each 'Cell' is not big enough. I would like each 'cell' content maximised, and the grid layout to remain spreadsheet like, i.e. square, with rows and columns aligned.
I don't know how to put Headings on each of the Columns that would align with the cells in each column.
So the display looks like this below. This is the closest to what I want, but for the size of the cell contents and the column headers.
As you can see there is plenty of room to make the numbers and letters bigger. I've tried many variations using Viewbox in the XAML. For example, wrapping the ListView in a Viewbox produces this which is no good as the columns are misaligned.
If I put Viewbox around each Bordercontrol that defines a 'cell' I still get problems with the layout too.
I've tagged this post with WPF despite my problem being in a UWP context in case someone has had a similar experience in that domain that could be applied here.

UPDATE:
#Grace Feng, your answer to use the lvwPlayers loaded event before assignment of the DataContext gives the following output which is NOT what I wanted. To begin with the rows are of different heights for no reason??:
Base on your description, I think there is no need to use the UniformGridPanel, you can simply customize a Grid to make its Height equals its Width. For example, create a TemplatedControl like this:
public sealed class SquareGrid : Grid
{
public SquareGrid()
{
this.Loaded += SquareGrid_Loaded;
}
private void SquareGrid_Loaded(object sender, RoutedEventArgs e)
{
this.Height = this.ActualWidth;
}
}
And for the question of "I don't know how to put Headings on each of the Columns that would align with the cells in each column.", I think you can set them as the Header of ListView. But it's very wise of you to use ViewBox to make the Text fill the size. Here comes the demo:
<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}" Width="900">

Which currently looks like this:
I tried adding a DataTemplate.Triggers but it doesn't seam to do anything. How exactly do you detect that a row in a itemscontrol has been selected? The only examples I have found use a datagrid. I tried changing mine to a datagrid instead of the itemscontrol, but then the it wouldn't load the data.
Datagrid:
<DataGrid x:Name="grd" Background="White" DataContext="{Binding DatabaseServers}" Grid.Row="2">
<Image Source="{Binding StatusImage}" Height="10" Width="10" />
<Label Grid.Column="1" HorizontalAlignment="Left" Content="{Binding ServerName}" />
<Label Grid.Column="2" HorizontalAlignment="Left" Content="{Binding SourceDatabase}" />
<TextBox x:Name="dst" Grid.Column="3" Text="{Binding DestinationDatabase , Mode=TwoWay, UpdateSourceTrigger=LostFocus}" VerticalAlignment="Top" />
<Label Grid.Column="4" Content="{Binding Status}" VerticalAlignment="Top" />
<Button Grid.Column="4" BorderThickness="0" HorizontalAlignment="Center" Width="50" Margin="3" Content="{Binding Status}" Command="{Binding EnabledCommand}" CommandParameter="{Binding}" />
</DataGrid>
Just shows a bunch of lines there is no data in each row.
I am very new to WPF so I cant really figure out what I am doing wrong here.
Here is what you want using DataGrid i m using MVVM

};
}
}

}
I'm trying to make a PropertyGrid Custom Control. The PropertyGrid will be very similar to the PropertyGrid used in Visual Studio. I've tried using the PropertyGrid of the Extended WPF Toolkit but you have to specify the category of a property with an attribute and we need to change the categories runtime. Which as far as I know is impossible with attributes.
So I'm making the PropertyGrid myself. This is my code so far:

group1.Items.Add(new PropertyGridItem("Item1", "test"));
group1.Items.Add(new PropertyGridItem("Item2", 300));
group1.Items.Add(new PropertyGridItem("Item3", true));
group1.Items.Add(new PropertyGridItem("Item4", 5.2));
Groups.Add(group1);
PropertyGroup group2 = new PropertyGroup();
group2.Name = "Group2";
group2.Items.Add(new PropertyGridItem("Item1", "test"));
group2.Items.Add(new PropertyGridItem("Item2", 300));
group2.Items.Add(new PropertyGridItem("Item3", true));
group2.Items.Add(new PropertyGridItem("Item4", 5.2));
Groups.Add(group2);
}
}
The problem I'm having is that the GridSplitter is applied every row. I want the GridSplitter to be applied to all rows of a group. I understand that this is because I make a new Grid for every item. For the attached properties to work the items have to be a direct child of the Grid.
A DataGrid also isn't an option because the GridSplitter is only available between column headers.
So to make a long story short: how can I use a Grid in an ItemsControl with a GridSplitter that applies to all rows of ideally a group or the entire Grid if that isn't possible.
I finally found the solution to this problem.
To get this to work I had to:
Set the Grid.IsSharedSizeScope to true on the parent ItemsControl.
Set the SharedSizeGroup property on the name column with an arbitrary name.
Remove the star sizing on the name column. Having both the first and third column with star sizing resulted in a stuck GridSplitter for some reason.
Set a fixed width on the GridSplitter, I set the Width to 2.
Set the ResizeBehaviour of the GridSplitter to PreviousAndNext.
Here is a relevant piece of the resulting code:
<ItemsControl ItemsSource="{Binding Items}" Grid.IsSharedSizeScope="True">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Grid Visibility="{Binding ElementName=toggleButton, Path=IsChecked, Converter={StaticResource BoolToVisConverter}}" >
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" SharedSizeGroup="nameColumn"/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Border Grid.Column="0" Style="{StaticResource BodyPropertyGrid_CellBorder}">
<TextBlock Text="{Binding Path=Name}"/>
</Border>
<GridSplitter Grid.Column="1" Width="2"
ResizeBehavior="PreviousAndNext"
Style="{StaticResource BodyPropertyGridSplitter}"/>
<Border Grid.Column="2" Style="{StaticResource BodyPropertyGrid_CellBorder}">
<ContentControl Content="{Binding}"
ContentTemplateSelector="{StaticResource propertyItemTemplateSelector}"/>
</Border>
</Grid>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
Unfortunately you didn't provide us with a nice simple piece of code that only demonstrates your problem and I don't have time to get it to compile and run in my test project, so I can only give you suggestions and not tested solutions. Next time, please take the time to show a code example that we can just copy and paste into a project.
You might be able to get your 'stretched' GridSplitter if you join all of the row Grids using the Grid.IsSharedSizeScope Attached Property:
<Grid Visibility="{Binding ElementName=toggleButton, Path=IsChecked, Converter=
{StaticResource BoolToVisConverter}}" Grid.IsSharedSizeScope="True">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" SharedSizeGroup="FirstColumn" />
<ColumnDefinition Width="Auto" SharedSizeGroup="GridSplitterColumn" />
<ColumnDefinition Width="*" SharedSizeGroup="LastColumn" />
</Grid.ColumnDefinitions>
...
</Grid>
