[Solved] disable optionlist for child items

[Mallikarjun]

Hi,

This is my sample for listing departments as Option list & employees as child items of each department. For departments, the option list is visible. However, i don't the optionlist for the child items. Please let me know how can i achieve this.
PS: I have attached the screen shot of the below code. I want the radio button to be visible only for "RND" and "Sales" items.

<Grid x:Name="LayoutRoot" Background="White">
       <Grid.Resources>
           <local:DepartmentCollection x:Key="departments"></local:DepartmentCollection>
           <DataTemplate x:Key="EmployeeTemplate">
               <TextBlock FontWeight="ExtraBold" Text="{Binding EmployeeName}"></TextBlock>
           </DataTemplate>
           <telerik:HierarchicalDataTemplate x:Key="DepartmentTemplate" ItemsSource="{Binding Employees}" ItemTemplate="{StaticResource EmployeeTemplate}"
                                            >

               <TextBlock Text="{Binding DepartmentName}"></TextBlock>
           </telerik:HierarchicalDataTemplate>

       </Grid.Resources>
       <telerik:RadTreeView IsOptionElementsEnabled="True" ItemsSource="{StaticResource departments}" Name="rdTreeView"
                                     ItemTemplate="{StaticResource DepartmentTemplate}"
                                    ItemsOptionListType="OptionList"
                                    telerik:StyleManager.Theme="Summer"
                                    IsTriStateMode="True">


       </telerik:RadTreeView>
   </Grid>

Hi Mallikarjun,

In your case it would be better to create a RadioButton in the DeoartmentTemplate and not use the CheckBox support of the RadTreeView:

<Grid x:Name="LayoutRoot" Background="White">
       <Grid.Resources>
             <local:DepartmentCollection x:Key="departments"></local:DepartmentCollection>
           <DataTemplate x:Key="EmployeeTemplate">
               <TextBlock FontWeight="ExtraBold" Text="{Binding EmployeeName}" />
           </DataTemplate>
           <telerik:HierarchicalDataTemplate x:Key="DepartmentTemplate"
                                             ItemsSource="{Binding Employees}"
                                             ItemTemplate="{StaticResource EmployeeTemplate}">
               <StackPanel Orientation="Horizontal">
                   <RadioButton Margin="0,0,5,0" GroupName="TreeViewGroup"/>
                   <TextBlock Text="{Binding Header}" />
               </StackPanel>
           </telerik:HierarchicalDataTemplate>

       </Grid.Resources>
       <telerik:RadTreeView Name="rdTreeView"
                            IsOptionElementsEnabled="True"
                            ItemsSource="{StaticResource departments}"
                            ItemTemplate="{StaticResource DepartmentTemplate}"
                            telerik:StyleManager.Theme="Summer" />
   </Grid>

Give this a try and let us know if it helps.

All the best,
