[Solved] ValidatesOnDataErrors

[Yonggu Kang]

Hi Telerik team,

I have no luck to display validation error mark whatever setting is.
My xaml is as follows. Pls have a look and let me what is wrong.

<telerik:RadTreeListView x:Name="taskTreeList" Grid.Column="2" ItemsSource="{Binding Path=Model}" Style="{StaticResource treeListStyle}"
                               SelectedItem="{Binding Path=SelectedRow,Mode=TwoWay}"  ValidatesOnDataErrors="InViewMode"
                                      telerik:RadDragAndDropManager.AllowDrop="True" IsDragDropEnabled="True" DragCueItemTemplate="{StaticResource TaskLineTemplate}">
               <telerik:RadTreeListView.ChildTableDefinitions>
                   <telerik:TreeListViewTableDefinition ItemsSource="{Binding Path=ChildTasks}" />
               </telerik:RadTreeListView.ChildTableDefinitions>
               <telerik:RadTreeListView.Columns>
                   <telerik:GridViewDataColumn Header="업무 절차" IsReadOnly="True" DataMemberBinding="{Binding Path=TaskName}" TextAlignment="Left" Width="0.65*" HeaderTextAlignment="Center" ValidatesOnDataErrors="InViewMode"/>
                   <telerik:GridViewCheckBoxColumn Header="최초 시작업무" DataMemberBinding="{Binding Path=InitTask,Mode=TwoWay}"
                                                IsReadOnlyBinding="{Binding Path=IsNotTask}" TextAlignment="Left" Width="0.35*" HeaderTextAlignment="Center" ValidatesOnDataErrors="InViewMode"/>
               </telerik:RadTreeListView.Columns>
           </telerik:RadTreeListView>

My business object is certain there is error, and I tried with 'InView/InEdit/Default' in treelistview only and
both in column as above but no luck.

p.s. I always in radgridview without problem.

Thank you in advance.

Hi Yong-Gu Kang,

I have prepared a sample project for you, which depicts a RadTreeListView validation case. You may test the functionality by editing the child elements. Please, have a look at it and inform us, if this solutions fits into your requirements.
