I want to bind to a specific item of my itemsControl (named maskDataBinding). I tried this:
<VisualBrush Visual="{Binding ElementName=maskDataBinding,Path=[0]}"/>
but it doesnt work. Also, could I bind the index as well? I have a slider and would like to update the item it is binded to when I adjust the slider.
Something like this:
<VisualBrush Visual="{Binding ElementName=maskDataBinding,Path=[{Binding ElementName=ScaleXSlider, Path=Value]}"/>
Edit:
Here is maskDataBinding simplified
<!--Outer collection-->
<ItemsControl Name="maskDataBinding">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<Canvas Background="Transparent"/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<!--nested collection-->
<ItemsControl Background="Transparent" ItemsSource="{Binding ImageSource}>
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<Canvas Background="Transparent"</Canvas>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<Image Source="{Binding Name}"</Image>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>

I have a lot of RadioButtons and Checkboxes and I basically want to split them in a second Column, to make it look more user friendly. I found some examples but not really for WPF.
Picture of Buttons
and this is my XAML:
<Grid>
<ItemsControl ItemsSource="{Binding AuswahlOptionenViewModelCollection}" Margin="115,50,0,0">
<ItemsControl.ItemTemplate>
<DataTemplate DataType="antwortmoeglichkeiten:OptionViewModel">
<Viewbox Height="25" HorizontalAlignment="Left" VerticalAlignment="Top">
<CheckBox Style="{DynamicResource MaterialDesignUserForegroundCheckBox}"
CommandParameter="{Binding}"
Command="{Binding SelectedOptionViewModelCommand}"
IsChecked="{Binding Selected}"
Content="{Binding Value}"/>
</Viewbox>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</Grid>
You can change ItemsPanel and use UniformGrid with 2 columns:
<ItemsControl ...>
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<UniformGrid Columns="2"/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
...
</ItemsControl.ItemTemplate>
</ItemsControl>
I have an ItemsControl with materialDesign Chips as a DataTemplate. My goal is to place the items one after the other without a lot of space in between.
There is a pic what is now looks like: https://imgur.com/hicWnGg.png

I tried already the ItemContainerStyle with Margin but this didnt helped me out
My Current Code
<ScrollViewer VerticalScrollBarVisibility="Disabled" HorizontalScrollBarVisibility="Auto">
<ItemsControl x:Name="myItemsControl" Height="40" Margin="0 10 0 0">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<UniformGrid Rows="1"/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<materialDesign:Chip Tag="{Binding Name}" Uid="{Binding SourceName}" Content="{Binding Code}" Width="75" IsDeletable="True" DeleteClick="Chip_DeleteClick"/>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</ScrollViewer>
Change your ItemsPanelTemplate to StackPanel instead of UniformGrid
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal"/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
I have the following datatemplate:
<ItemsControl x:Name="Groups" ItemsSource="{Binding Groups}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<StackPanel x:Name="GroupStackPanel" Orientation="Horizontal">
<GroupBox Header="{Binding Path=GroupName}">
<ItemsControl ItemsSource="{Binding Buttons}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<StackPanel x:Name="BtnStackPanel" Orientation="Horizontal">
<Button Content="{Binding Path=LabelString}"
Command="{Binding Path=ButtonCommand}"/>
</StackPanel>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</GroupBox>
</StackPanel>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
This includes some ButtonGroups and Buttons which are in this Group.
The class Group includes a string-property "GroupName" and an ObservableCollection-property "Buttons". The allocation of buttons and groups is working correctly.
So here is my problem: I want to have this buttongroups in a ribbontab in the dockpanel. But the alignment or the orientation is false, so the buttons are one below the other and not next to each other.
Has anyone an idea what is wrong in my code?
At the moment, you're using a Stackpanel with horizontal orientation, which is the right idea, but the Stackpanel is in the wrong place (the ItemTemplate). The ItemTemplate is applied to every item in an ItemsControl, which means that your XAML represents a collection of buttons where each is surrounded by its very own StackPanel.
To have the desired effect, you instead need to specify the Stackpanel as the ItemsPanelTemplate of the ItemsControl.
Try changing your inner clause to:
<ItemsControl ItemsSource="{Binding Buttons}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Button Content="{Binding Path=LabelString}" Command="{Binding Path=ButtonCommand}"/>
</DataTemplate>
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel x:Name="BtnStackPanel" Orientation="Horizontal">
</ItemsPanelTemplate>
<ItemsControl.ItemsPanel>
</ItemsControl>
Edit
If you want both groups and buttons to display horizontally, you can do the same thing to both:
<ItemsControl x:Name="Groups" ItemsSource="{Binding Groups}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<GroupBox Header="{Binding Path=GroupName}">
<ItemsControl ItemsSource="{Binding Buttons}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Button Content="{Binding Path=LabelString}" Command="{Binding Path=ButtonCommand}"/>
</DataTemplate>
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel x:Name="BtnStackPanel" Orientation="Horizontal"/>
</ItemsPanelTemplate>
<ItemsControl.ItemsPanel>
</ItemsControl>
</GroupBox>
</DataTemplate>
</ItemsControl.ItemTemplate>
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel x:Name="GroupStackPanel" Orientation="Horizontal"/>
</ItemsPanelTemplate>
<ItemsControl.ItemsPanel>
</ItemsControl>
I am using ItemsControl and have several buttons and place them at a specific location on the canvas. However, the Canvas.Left and Canvas.Top always place all buttons at 0,0.
<ItemsControl x:Name="itemsControl" ItemsSource="{Binding Tiles}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<Canvas />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<Button Width="{Binding Side}"
Height="{Binding Side}"
Background="{Binding BgColor}"
Canvas.Left="{Binding Left}" Canvas.Top="{Binding Top}" />
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
The best answer I've found for this is to use a RenderTransform in your datatemplate
<ItemsControl x:Name="itemsControl" ItemsSource="{Binding Tiles}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<Canvas />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<Button Width="{Binding Side}" Height="{Binding Side}" Background="{Binding BgColor}">
<Button.RenderTransform>
<TranslateTransform X={Binding Left} Y ={Binding Top}/>
</Button.RenderTransform>
</Button>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
I was unable to find a solution for this problem:
I am creating my own table with ItemControls. To resize the columns I'd like to bind the Width-property of one cell to the corresponding ActualWidth-property of the column.
I tried the following, but it is not working:
<StackPanel Orientation="Vertical">
<Border BorderBrush="Black" BorderThickness="1">
<ItemsControl ItemsSource="{Binding Data.Columns}" Margin="26,1,1,1">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal"/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<!-- here i set the name of the column (Code) -->
<Border BorderBrush="Black" BorderThickness="1,0,0,0" Width="100" x:Name="{Binding Code}">
<TextBlock Text="{Binding Header}" />
</Border>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</Border>
<ItemsControl ItemsSource="{Binding Data.Rows}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Vertical" />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<Border BorderBrush="Black" BorderThickness="1,0,1,1">
<StackPanel Orientation="Horizontal" Margin="1">
<Grid Width="25">
<General:SeverityIconControl Severity="{Binding Severity}" />
</Grid>
<ItemsControl ItemsSource="{Binding Values}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal"/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<!-- and here i'd like to bind to the ActualWidth of the corresponding column (Code)
but it is not working because ElementName={Binding LocalCode} does not work -->
<Border BorderBrush="Black" BorderThickness="1,0,0,0" Width="{Binding ActualWidth, ElementName={Binding LocalCode}}">
<TextBlock Text="{Binding Value}" />
</Border>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</StackPanel>
</Border>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</StackPanel>
Is there a way to solve this without changing the data source (unfortunately the data source cannot be edited)?
You can't bind x:Name (more info here) since it's only read when you call InitializeComponent() in the constructor.
Easiest way would be to add a DesiredWidth column to your Data object, and bind both widths to that (with a default value of 100).
