ScrollBar not Appearing - c#

I am having problems getting the scrollbars to show in my InfoWindow. Code is below. Any help would be appreciated.
XAML:
<DataTemplate x:Key="MyFeatureLayerInfoWindowTemplate">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<ItemsControl ItemsSource="{Binding Keys}" Grid.Column="0" />
<ItemsControl ItemsSource="{Binding Values}" Grid.Column="1" />
</Grid>
</DataTemplate>
<esri:InfoWindow x:Name="MyInfoWindow"
CornerRadius="20"
ContentTemplate="{StaticResource MyFeatureLayerInfoWindowTemplate}"
Map="{Binding ElementName=MyMap}"
MouseLeftButtonUp="MyInfoWindow_MouseLeftButtonUp"
ScrollViewer.VerticalScrollBarVisibility="Visible"
ScrollViewer.HorizontalScrollBarVisibility="Visible"
Background="{DynamicResource {x:Static SystemColors.WindowBrushKey}}"
MaxHeight="200"
MaxWidth="200"/>
C#:
if (clickpoint != lastPoint)
{
MyInfoWindow.Anchor = clickpoint;
MyInfoWindow.Content = e.Graphic.Attributes;
MyInfoWindow.IsOpen = true;
lastPoint = clickpoint;
}
Picture of what I am seeing:
The content appears in the InfoWindow, but the scrollbars are nowhere to be found. Hopefully it is something simple, I feel like I have tried everything. Thanks in advance.

Try this
<DataTemplate x:Key="MyFeatureLayerInfoWindowTemplate">
<ScrollViewer HorizontalScrollBarVisibility="Hidden" VerticalScrollBarVisibility="Auto">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<ItemsControl ItemsSource="{Binding Keys}" Grid.Column="0" />
<ItemsControl ItemsSource="{Binding Values}" Grid.Column="1" />
</Grid>
</ScrollViewer>
</DataTemplate>
I mean: wrap the grid inside a ScrollViewer

Insert Labels with ItemsControl in Grid

I want to sort Labels from an ItemsControl to my Grid.
When I bind the Grid.Row and Grid.Column properties, the position of the column and row is not effected.
What am I doing wrong?
Labels have the wrong positions in the grid
Here my View.xaml
<Window.Resources>
<vm:MainViewModel x:Key="MainVM"/>
</Window.Resources>
<DockPanel DataContext="{StaticResource MainVM}">
<Grid Width="500">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<ItemsControl
ItemsSource="{Binding MachineList}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Border BorderBrush="Black" Background="Gainsboro" BorderThickness="1" Margin="2">
<Label Content="{Binding SerialNumber}"
Grid.Column="{Binding StationNumber}"
Grid.Row="{Binding LineNumber}"
Margin="0"
VerticalAlignment="Center"
HorizontalAlignment="Center"
Background="LightBlue"
/>
</Border>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</Grid>
</DockPanel>
Here my MainViewModel.cs
public class MainViewModel: BaseViewModel
{
public ObservableCollection<Machine> MachineList { get; set; }
public MainViewModel()
{
Machine m1 = new Machine(0, "Row1 Column3", 1, 3, MachineType.SX);
Machine m2 = new Machine(0, "Row1 Column2", 1, 2, MachineType.SX);
Machine m3 = new Machine(0, "Row2 Column1", 2, 1, MachineType.SX);
MachineList = new ObservableCollection<Machine>();
MachineList.Add(m1);
MachineList.Add(m2);
MachineList.Add(m3);
}
}
The problem is that the ItemsControl displays the items in its own panel, which is no your grid so the grid property have no effect on the location of the items. The correct way to do this is to define your grid in the ItemsControl.ItemsPanel property like this:
<ItemsControl
ItemsSource="{Binding MachineList}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Border BorderBrush="Black" Background="Gainsboro" BorderThickness="1" Margin="2">
<Label Content="{Binding SerialNumber}"
Margin="0"
VerticalAlignment="Center"
HorizontalAlignment="Center"
Background="LightBlue"
/>
</Border>
</DataTemplate>
</ItemsControl.ItemTemplate>
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<Grid Width="500">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
</Grid>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemContainerStyle>
<Style>
<Setter Property="Grid.Row" Value="{binding ...}" />
<Setter Property="Grig.Column" Value="{binding ...}" />
</Style>
</ItemsControl.ItemContainerStyle>
</ItemsControl>

UWP: Cannot make ListView scrollable

I have a page with a simple grid (2x2). In one grid on the bottom left corner is another Grid and inside this grid is a ListView bound to a collection. Entries can be added to the collection so the ListView grows in height (height of ListView is set to auto, so that all space available is used).
What I want is, if all available space (from the screen height) is used, scrollbars for the ListView should appear and should be usable. Funny (unfunny) thing is: scrollbars do appear but I cannot use them, I cannot scroll the ListView with the vertical scrollbar that appears when I hover the ListView.
It works, when I set the height of the ListView to a fixed value, but I don't want it that way, because then it doesn't use all the available space on the screen.
This is the XAML of the page (I removed some parts for demonstration purposes) :

Can someone spot why it is behaving this way?
You need to set the height of the second row to "*" for both grids.

Confused wpf grid behaviour in DataTemplate

I am confused about the Grid's behaviour inside a ContentTemplate:
I want to style my ListView:
<Setter Property="ContentTemplate">
<Setter.Value>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="auto"/>
<ColumnDefinition Width="auto"/>
<ColumnDefinition Width="auto"/>
</Grid.ColumnDefinitions>
<TextBlock Text="{Binding ArticleID}"
Grid.Column="0"
/>
<TextBlock Text="{Binding ArticleName}"
Grid.Column="1"
/>
<Button Command="{Binding DataContext.RemoveComponentFromVehicle, RelativeSource={RelativeSource AncestorType=Grid}}"
Grid.Column="2"
>
<Button.Content>
<StackPanel Style="{StaticResource IconTextCombo}">
<Image Source="{StaticResource ComponentToVehicle_Delete}"/>
</StackPanel>
</Button.Content>
</Button>
</Grid>
As you can see, I want to make sure that my buttons align right on the right side because the ArticleID and Name length can vary.
The buttons aren't align as I want and expect. I have a test project:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="auto"/>
<ColumnDefinition Width="auto"/>
<ColumnDefinition Width="auto"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<TextBox Text="Foo"
Grid.Column="0"/>
<TextBox Text="Bar"
Grid.Column="1"/>
<Button Content="DELETE"
Grid.Column="2"/>
<TextBox Text="Hello World"
Grid.Column="0"
Grid.Row="1"/>
<TextBox Text="LONG TEXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXT"
Grid.Row="1"
Grid.Column="1"/>
<Button Content="DELETE"
Grid.Row="1"
Grid.Column="2"/>
</Grid>
In this 'hardcoded' version every aligns as I want... I don't know why my grid is so weird in the Template. Can someone help me?
Thanks in advance!
Here is the solution after working around:
<ListView DockPanel.Dock="Right"
ItemsSource="{Binding}"
SelectedItem="{Binding }"
Name="lvMain"
HorizontalContentAlignment="Stretch"
>
<ListView.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="auto"/>
<ColumnDefinition />
<ColumnDefinition Width="auto"/>
</Grid.ColumnDefinitions>
<TextBlock Text="{Binding ArticleID}"
Grid.Column="0"
/>
<TextBlock Text="{Binding ArticleName}"
Grid.Column="1"
/>
<Button Command="{Binding }"
Grid.Column="2"
>
<Button.Content>
<StackPanel Style="{StaticResource IconTextCombo}">
<Image Source="{StaticResource img}"/>
</StackPanel>
</Button.Content>
</Button>
</Grid>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
I have tested it with ListBox and ListView... It works for both of them as I want now!
Thanks to all helpers!
you need to use the SharedSizeGroup property on your grid in your template. It works in your hardcoded example because all your elements sit inside the same grid. Once you place them inside a ListBox every item has its own grid and is unaware of the other grids.
Setting this property will make sure all these columns have the same size regardless which grid they are in.
your Grid.ColumnsDefinitions should look like this:
<Grid.ColumnDefinitions>
<ColumnDefinition Width="auto" SharedSizeGroup="ColumnA"/>
<ColumnDefinition Width="auto" SharedSizeGroup="ColumnB"/>
<ColumnDefinition Width="auto" SharedSizeGroup="ButtonsColumn"/>
</Grid.ColumnDefinitions>
You should also use ItemTemplate meaning:
<ListBox>
<ListBox.ItemTemplate>

</ListBox.ItemTemplate>
</ListBox>

Grid covers another on resizing in WPF

In a GroupBox I have two grids: the 1st one contains can contain lots of textboxes so that I added a ScrollViewer, the 2nd one contains action buttons that must allways be visible.
A 2nd GroupBox above has an Expander and the problem is that when it is expanded and the 1st grid has enough elements, it covers the 2nd grid with buttons. How can I fix this?
Here my code:
<Window x:Class="ControlOverlayBug.MainWindow"

Give your ScrollViewer a MaxHeight to get the scroll working instead of overlapping
Well, I solved the problem by changing the DockPanel (named BindPanel) by a Grid with two rows (the 2nd row has a fixed height) and it works. Here the interesting part:
<GroupBox DockPanel.Dock="Bottom" Header="Other Parameters">
<Grid x:Name="BindPanel" VerticalAlignment="Stretch" Background="Beige">
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition Height="24"/>
</Grid.RowDefinitions>
<ScrollViewer VerticalScrollBarVisibility="Auto" VerticalAlignment="Top">
...
</ScrollViewer>
<!-- grid wih buttons -->
</Grid>
</GroupBox>

WPF - width issue with IsSharedSizeScope "true" and three columns

Simple code:
<ItemsControl Grid.IsSharedSizeScope="True" >
<ItemsControl.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition SharedSizeGroup="firstColumn" Width="Auto"/>
<ColumnDefinition SharedSizeGroup="splitterColumn" Width="Auto"/>
<ColumnDefinition SharedSizeGroup="lastColumn" Width="*"/>
</Grid.ColumnDefinitions>
<TextBlock Text="{Binding Path=Key}"/>
<GridSplitter Width="5" Grid.Column="1" />
<TextBlock Text="{Binding Path=Value}" Grid.Column="2"/>
</Grid>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
Problem is occured with lastColumn, width of it is not 100%. I try to set HorizontalAlignment="Stretch" for the all grids but it didn't help.
Width of lastColumn must be 100%. How to resolve this issue?
You don't need to include SharedSizeGroup on every column. In this case, if your first and second columns are sharing a size, you should be able to get your desired behaviour by omitting the property on the last column. There should always be the same amount of space for the last column, if the first two columns are sharing sizes:
<Grid Width="300" Height="30" Background="Red">
<Grid Grid.IsSharedSizeScope="True">
<Grid.ColumnDefinitions>
<ColumnDefinition SharedSizeGroup="firstColumn" Width="Auto"/>
<ColumnDefinition SharedSizeGroup="splitterColumn" Width="Auto"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<TextBox Text="1" Grid.Column="0"/>
<GridSplitter Width="5" Grid.Column="1"/>
<TextBox Text="Test" Grid.Column="2" />
</Grid>
</Grid>
Edit: This is essentially the problem encountered here: Grid.IsSharedScopeSize incompatible with * columns in WPF Grid
Further edit: You've changed to an ItemsControl now, but the same should still apply.
