WPF - Itemssource in a Button - wpf

everyone,
I would like to add an Itemsource to a button so that I can access the sub-values. If I do the whole thing with ItemsControl, I get a button for each value. However, I only need one button. Can i limit this?
My Output: 30 Buttons -> I need 1.
My WPF Code:
<ItemsControl ItemsSource="{Binding Rechte}" >
<ItemsControl.ItemTemplate>
<DataTemplate>
<StackPanel>
<Button Content="Löschen" Command="{Binding FoerderLoeschen}" FontSize="{Binding SelectedFont, UpdateSourceTrigger=PropertyChanged}" Visibility="{Binding Rechte.CanDelFPFoer, Converter={StaticResource BoolToVis}}" Padding="5 5 5 5" Margin="5 15 5 0"/>
</StackPanel>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>


Wrap the ItemsControl with a button so it becomes the button's content:
<Button>
<ItemsControl ItemsSource="{Binding Rechte}" >
<ItemsControl.ItemTemplate>
<DataTemplate>
<StackPanel>
<Button Content="Löschen" Command="{Binding FoerderLoeschen}" FontSize="{Binding SelectedFont, UpdateSourceTrigger=PropertyChanged}" Visibility="{Binding Rechte.CanDelFPFoer, Converter={StaticResource BoolToVis}}" Padding="5 5 5 5" Margin="5 15 5 0"/>
</StackPanel>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</Button>

How to get value of textblock in mvvm

I have an ItemControl containing a list of elements.
I need to get the value of the TextBlock using MVVM.
This is my XAML code:
<ItemsControl ItemsSource="{Binding IhmtEcosystemFilterList}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Button Margin="5" Height="80" Background="LightBlue" BorderBrush="Black" Command="{Binding CmdStatistiqueEcoSystem, ElementName={Binding Name}}">
<StackPanel Width="150">
<TextBlock Text="{Binding Name}" Foreground="White" FontSize="17" Name="valueTxtBloc" />

</StackPanel>
</Button>

WPF - adding user control to listbox

I am trying to add a usercontrol to a ListBox.
My usercontrol contains a collection of basic elements like textbox and dropdowns, in a fashion so that it creates a row of elements.
The code for ListBox in my main window is as -
<GroupBox FontWeight="SemiBold" Foreground="#FF0CAEF9" Name="gbAddProducts" Style="{x:Null}" Header="ADD PRODUCTS" HorizontalAlignment="Left" Margin="0,256,0,0" VerticalAlignment="Top" Width="990" Height="207">
<ListBox Name="lstboxAddProduct" ItemsSource="{Binding Path=AddNewProductRowViewModelList, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged, ValidatesOnDataErrors=True}" BorderThickness="0" Margin="0,10,-2,23">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Vertical">
<ContentControl Content="{Binding AddNewProductRowViewModel}" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
<Validation.ErrorTemplate>
<ControlTemplate>
<StackPanel>
<AdornedElementPlaceholder x:Name="aepForError"/>
<ItemsControl ItemsSource="{Binding}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding ErrorContent}" Foreground="White" Background="#DC000C" />
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</StackPanel>
</ControlTemplate>
</Validation.ErrorTemplate>
</ListBox>
</GroupBox>
Here AddNewProductRowViewModelList is my user control list containing 5 controls.
The Problem that I see is that when I run the code, the screen has 5 rows, ie I can click on the area to figure out theer are 5 rows as that section gets highlighted. But they are not visible.
Could it be some 'bring to front' sort of issue.
Please advise.
Thanks in advance.

I would do it this way instead:
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Vertical">
<ContentControl>
<local:AddNewProductRowView Datacontext="{Binding AddNewProductRowViewModel}"/>
</ContentControl>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>

How to edit an item in the treeview in wpf

My TreeView ItemTemplate looks like below.
<TreeView.ItemTemplate>
<HierarchicalDataTemplate ItemsSource="{Binding Connections}">
<WrapPanel >
<CheckBox VerticalAlignment="Center" Command="{Binding UpdateConnections}" CommandParameter="{Binding}" IsChecked="{Binding Status, Mode=TwoWay}" Focusable="False" Style="{StaticResource ResourceKey=TreeView_CheckBox_Style}"></CheckBox>
<TextBlock Text="{Binding Name}" Style="{StaticResource ResourceKey=treeTextBoxStyle}" />
</WrapPanel>
</HierarchicalDataTemplate>
</TreeView.ItemTemplate>
I am using MVVM. I would like to edit the TextBox if my tree item starts with "s".
I basically double click my TreeViewItem and I should be able to type in it.
How do i do it ?

Can use a wrappanel with datatemplate for horizontal alignment of items in a listbox

I am trying to horizontally align items in a listbox(items are checkbox items). How can i use a wrap panel with datatemplate?
<ListBox Name="Horizontal" ItemsSource="{Binding Solution}" scrollViewer.HorizontalScrollBarVisibility="Disabled" >
<ListBox.ItemTemplate >
<DataTemplate >
<CheckBox Content="{Binding Name}" IsChecked="{Binding IsChecked}" Margin="5 5 0 0"/>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>

I think you want the ItemsPanel property:
<ListBox Name="Horizontal" ItemsSource="{Binding Solution}" scrollViewer.HorizontalScrollBarVisibility="Disabled">
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel Orientation="Horizontal"/>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemTemplate>
<DataTemplate>
<CheckBox Content="{Binding Name}" IsChecked="{Binding IsChecked}" Margin="5 5 0 0"/>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>

Showing a collection of items inside of a ItemsControl horizontally

Here is the XAML markup:
<ScrollViewer Grid.Column="1" Grid.Row="2" HorizontalScrollBarVisibility="Disabled" Width="990">
<StackPanel Margin="50 0 0 40">
<ItemsControl x:Name="streamList" ItemsSource="{Binding StreamInformations}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<StackPanel Margin="10" Orientation="Horizontal" >
<StackPanel Orientation="Horizontal">
<Image Source="{Binding ImageUrl}" Height="60" />
<StackPanel Margin="10 0 0 0" VerticalAlignment="Center">
<TextBlock Foreground="Black" Text="{Binding ChannelName}" FontSize="12" />
<TextBlock Foreground="#999" Text="{Binding PlayerName}" FontSize="10" />
<TextBlock Foreground="#999" Text="{Binding ViewCount}" FontSize="10" />
</StackPanel>
</StackPanel>
</StackPanel>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</StackPanel>
</ScrollViewer>
And this is how it looks:
I'd like these items to appear horizontally and flow down when it reaches the edge of the StackPanel.
It seems that currently, each item in my DataContext collection is creating it's own StackPanel, so this isn't what I want.
Any suggestions?

If you change the ItemsPanel template to either a WrapPanel or horizontal StackPanel, you can achieve the effect you are after...
<ItemsControl>
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel Orientation="Horizontal"/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<!--other stuff here-->
</ItemsControl.ItemTemplate>
</ItemsControl>
In this snippet, the ItemsPanel is set to a WrapPanel oriented horizontally. The ItemTemplate would include the binding and styling you already have...
