How to disable tooltip for the first node of RadTreeView

[Divya]

Hi,

I have defined a custom tooltip for RadTreeView. Also I have used HierarchicalDataTemplate for my RadTreeView. Code is as shown below.

 <telerik:RadTreeView Margin="8" IsDragDropEnabled="True"  Name="CollExperimentTreeView"  SelectedItem="{Binding ActiveExp, Mode=TwoWay}"
     SelectionMode="Single" IsSingleExpandPath="False" IsLineEnabled="True"   VerticalAlignment="Stretch"
       temTemplate="{StaticResource TreeViewTemplate}"  ItemsSource ="{Binding TreeViewCollection,  Mode=TwoWay}" />

Custom tooltip and  HierarchicalDataTemplate  defined as below:

 <UserControl.Resources>
        <Style TargetType="{x:Type telerik:RadTreeViewItem}">
            <Setter Property="ToolTip" >
                <Setter.Value>
                    <ToolTip>
                        <ToolTip.Content>
                            <StackPanel Orientation="Vertical">
                                <StackPanel Orientation ="Horizontal">
                                    <TextBlock Text="Started:   " />
                                    <TextBlock Text="{Binding StartDate}" />
                                </StackPanel>
                                <StackPanel Orientation ="Horizontal">
                                    <TextBlock Text="Last Changed:   " />
                                    <TextBlock Text="{Binding LastAccess}" />
                                </StackPanel>
                                <TextBlock Text="{Binding Description}" />
                            </StackPanel>
                        </ToolTip.Content>
                    </ToolTip>
                </Setter.Value>
            </Setter>
        </Style>
        <HierarchicalDataTemplate x:Key="TreeViewTemplate" ItemsSource="{Binding Path=Experiments}">
            <TextBlock VerticalAlignment="Stretch" HorizontalAlignment="Stretch"  Text="{Binding Name}" />              
        </HierarchicalDataTemplate>
    </UserControl.Resources>

I do not want to display tooltip for those nodes that shows TextBlock containing Name,( HierarchicalDataTemplate )  

Please help

Thanks

Hi Divya,

You can use ItemContainerStyleSelector which will set Style will ToolTip on certain items and style with no tooltips on the other TreeViewItems. For the normal style you can just return base.SelectStyle in the StyleSelector class. We hope the following help article is a good starting point.

RadTreeView ItemContainerStyleSelector

Please let us know if you need further assistance with this requirement.
