I would like to have TreeViewItems configured inside a SwipeControl; this works but the tree gets spaced really ugly, because I can't find a way to shrink the size of the SwipeItem; any idea where to look next?
Here is my Treeview-XAML
<TreeView ItemsSource="{x:Bind fileViewModel.collection}">
<TreeView.ItemTemplate>
<DataTemplate x:DataType="vm:vTreeItem">
<TreeViewItem ItemsSource="{x:Bind Children}">
<SwipeControl Height="25">
<SwipeControl.RightItems>
<SwipeItems Mode="Execute">
<SwipeItem x:Name="DeleteSwipeItem"
Background="Red"
Command="{Binding Source={StaticResource ViewModel}, Path=deleteCmd}"
CommandParameter="{x:Bind Name}"/>
</SwipeItems>
</SwipeControl.RightItems>
<StackPanel Orientation="Horizontal" Height="25">
<Image Width="20" Height="20" Source="{x:Bind Icon}"/>
<TextBlock Text="{x:Bind Name}" Margin="10,0,0,0"
HorizontalAlignment="Left"
VerticalAlignment="Center"/>
</StackPanel>
</SwipeControl>
</TreeViewItem>
</DataTemplate>
</TreeView.ItemTemplate>
</TreeView>

My list view seems like that. And I want to remove or hide the items which are in top of the list view.

I am using MVVM architectural pattern to achieve this goal. The problem that I am facing is with the arrow head of second level node. It is not aligned at the right position. The arrowhead gets automatically aligned to "Text3" combo box instead of "Payload" node. Following is the image of my tree view
I do not know if there is any other approach to include Combo box, check box, text boxes inside a treeview using MVVM approach. Would appreciate if you let me know your approach of designing this treeview
How would I add an icon to each of these parent nodes
I tried adding under each TreeViewItem but the icon doesn't show and when I bind my collection to the ItemSource, it says it must be empty fist.
<TreeView x:Name="tvMessages" HorizontalAlignment="Left" Height="262" Margin="10,37,0,0" VerticalAlignment="Top" Width="248">
<TreeViewItem x:Name="itemsCritical" Header="Critical">
<TreeViewItem.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding Description}"/>
<TextBlock Text="{Binding ID}" Visibility="Hidden"/>
</StackPanel>
</DataTemplate>
</TreeViewItem.ItemTemplate>
</TreeViewItem>
<TreeViewItem x:Name="itemsAlert" Header="Alert">
<TreeViewItem.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding Description}"/>
<TextBlock Text="{Binding ID}" Visibility="Hidden"/>
</StackPanel>
</DataTemplate>
</TreeViewItem.ItemTemplate>
</TreeViewItem>
<TreeViewItem x:Name="itemsInformational" Header="Informational">
<TreeViewItem.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding Description}"/>
<TextBlock Text="{Binding ID}" Visibility="Hidden"/>
</StackPanel>
</DataTemplate>
</TreeViewItem.ItemTemplate>
</TreeViewItem>
</TreeView>
Take a look at this example:
<TreeViewItem Name="treeViewItem1" IsEnabled="True">
<TreeViewItem.Header>
<StackPanel Orientation="Horizontal">
<Image Height="16" Source="Images/16x16_red_lamp.png" Width="16" />
<TextBlock Margin="5,0" Text="HostA: Disconnected" />
</StackPanel>
</TreeViewItem.Header>
</TreeViewItem>
Just place the Image inside and tell the Source where is your Icon located.
You can also use HeaderTemplate in case you have Bindings against associated item.
<ListBox Height="498" Margin="2,0,0,0" Name="listBox1" Width="879" ItemsSource="{Binding}" >
<ListBoxItem >
<StackPanel Width="418" Orientation="Horizontal">
<TextBlock Name="MedicineName" Text="Alamoxy"
FontWeight="Bold" FontSize="18"
Margin="5" Width="205" >
</TextBlock>
<TextBlock Name="ListBoxLetter" Text="Amoksilin"
FontSize="18" Margin="0" Width="255" Height="23">
</TextBlock>
</StackPanel>
</ListBoxItem>
</ListBox>
I want to bind data to the listbox.
Textblock will show seprate fields. How i can do it?
please Help me about this/
Use an ItemTemplate to make it look something like this.
<ListBox Width="400" Margin="10" ItemsSource="{Binding myItems}">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
<TextBlock Text="{Binding Path=MedicineName}" />
<TextBlock Text="{Binding Path=ListBoxLetter}"/>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
I have a treeview in wpf that is built using the xaml below. It is a well structured data source, and I am having a lot of trouble dragging and dropping. I have tried several methods, all to no avail. Can anyone tell me what the standard procedure is for doing this type of thing?

i use the techniques on this site for a general drag and drop.
tree view can get messy, if you want to know which node you are preivewMouseDown'ing on, to then use as your drag item you can end up walking the visual tree. there is some code to do that here. another way is to subclass treeview, and treeviewitem, then you can override the preview mouse down on each tree view item, and tell your derived parent treeview about it, which could set the tree view item to be the selected item.
