Hello,

When I select a row and press delete the row is removed.
How can I reuse this command whit a button so that the delete options is more obvious for the user?

Thank you

Hello,

I tryied the code below but it seems not to be working. Is it correct to use the RaGrid delete command for the treelistview?
thanks
<telerik:RadButton Content="Delete" Margin="15,0,0,0" Command="telerikGrid:RadGridViewCommands.Delete" CommandTarget="{Binding ElementName=_pagesTreeList}"/>
 
<telerik:RadTreeListView x:Name="_pagesTreeList" CanUserDeleteRows="True" IsDragDropEnabled="True" AllowDrop="True" IsDragTooltipEnabled="False" DragCueItemTemplate="{StaticResource DragCueTreeList}" ItemsSource="{Binding PagesHierarchy, Mode=TwoWay}" AutoGenerateColumns="False" d:LayoutOverrides="Width, Height">

Hi Frederic,

There is no problem to use Delete command with RadTreeListView. Could you verify whether you have the required references added and the uri is correctly defined in your application ?

I have the following uri defined :

xmlns

 

 

:telerik="http://schemas.telerik.com/2008/xaml/presentation"

 

xmlns:telerikGrid="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.GridView"


and the following references:
Telerik.Windows.Controls
Telerik.Windows.Controls.GridView
Telerik.Windows.Controls.Input
Telerik.Windows.Data
Telerik.Windows.Themes.Expression_Dark

The delete key works but not the button

Hi Frederic,

Could you try to initialize the command before InitializeComponent() method:

public MainPage()
       {
           ICommand deleteCommand = RadGridViewCommands.Delete;
  
           InitializeComponent();
  
       }
