I am using RadTreeListView, provided the Xaml below.
I wanted to do validation for the text box column, similar to what is provided for GridView column, 'CellValidating' event where if validation logic fails, text box shows a comment, and the border will become red. Is this supported in RadTreeListView, how can I implement in my code?

 <telerik:RadTreeListView x:Name="MyTree" AutoGenerateColumns="False">
 <telerik:RadTreeListView.Columns>
                    <telerik:GridViewDataColumn x:Name="ObjNameColumn" Header="Name" DataMemberBinding="{Binding Name}" >
                        <telerik:GridViewDataColumn.CellStyle>
                            <Style TargetType="telerik:GridViewCell">
                                <Setter Property="Template">
                                    <Setter.Value>
                                        <ControlTemplate>
                                            <Border BorderBrush="LightGray" BorderThickness="0,0,1,0">
                                                <TextBox x:Name="txtBox_NewInstanceName"                                                   
                                                           HorizontalAlignment="Center" VerticalAlignment="Center"    
                                                            Text="{Binding Path=Name, Mode=TwoWay, UpdateSourceTrigger=LostFocus}">
                                                </TextBox>
                                            </Border>
                                        </ControlTemplate>
                                    </Setter.Value>
                                </Setter>
                            </Style>
                        </telerik:GridViewDataColumn.CellStyle>
                    </telerik:GridViewDataColumn>

Hello Smita,

You can implement validation in RadTreeListView in the same way as in RadGridView. Please refer to our online documentation for a reference.

<telerik:RadTreeListView x:Name="MyTree" AutoGenerateColumns="False" CellValidating="MyTree_CellValidating">

I have tried CellValidating for RadTreeListView but it never gets hit. That's why I was not sure if I am using it the right way or if it's not supported for TreeListView. Could you provide some code snippet for RadTreeListView where this has been implemented.
