  Hi,
  I is there a way to have custom tool tips for each comboboxitem in the combobox ?
  
  

  <telerik:RadComboBox Name="comboWorkingPlan" Height="20" Width="100"

  DisplayMemberPath="Name"

  SelectionChanged="comboWorkingPlan_SelectionChanged"

  SelectedItem="{Binding Source={StaticResource MainUIDataSource}, Path=Class, Mode=TwoWay}"

  ItemsSource="{Binding Source={StaticResource MainUIDataSource}, Path=PlansDataSource.AllClasses}" Initialized="comboWorkingPlan_Initialized"/>

  
  Lets say I have a property called "Description" for each Class, would I be able to display that as a tooltip ?
  
  Cheers
  Kristján

  Hi,
  
  It is possible using ItemContainerStyle and applying ToolTip in a Setter there bound to a property of your view model. Please refer to the attached project.

  Hi,
  
  In my project, I am facing one problem with the tooltip of the radcomboBox. It's like this -->
  
  I want to show a tooltip which displays the ID of the item when focus is placed on the combobox item.
  And also I am able to achieve this one perfectly. But what the problem I am facing now is -  The ComboBox items are not getting displayed in the container. Please help me out in resolving this.
  
  Regards
  K Siva Prakash.

  This is my code snippet.

<telerik:RadComboBox HorizontalAlignment="Center" 

                                            VerticalAlignment="Center"  

                                            Width="283" 

                                            ItemsSource="{Binding Items}"

                                            DisplayMemberPath="Name" 

                                            SelectedValuePath="Id" 

                                            SelectedValue="{Binding Path=SelectedItem, Mode=TwoWay}" 

                                            Margin="100,100">

              <telerik:RadComboBox.ItemContainerStyle>

                  <Style TargetType="telerik:RadComboBoxItem">

                      <Setter Property="Content" Value="{Binding Name}"/>

                      <Setter Property="ToolTip" Value="{Binding Id}"/>

                  </Style>

              </telerik:RadComboBox.ItemContainerStyle>

          </telerik:RadComboBox>

  Hi Siva Prakash,
  
  Please try the following XAML snippet instead. I believe you have a wrong Binding and a missing SelectionBoxTemplate.
  
  

  <Window.Resources>

          <DataTemplate x:Key="SelectionBoxTemplate">

              <TextBlock Text="{Binding Id}" />

          </DataTemplate>

      </Window.Resources>

      <Grid>

          <telerik:RadComboBox HorizontalAlignment="Center" 

                               VerticalAlignment="Center"  

                               Width="283"

                               ItemsSource="{Binding}" 

                               SelectionBoxTemplate="{StaticResource SelectionBoxTemplate}"

                               Margin="100,100">          

              <telerik:RadComboBox.ItemContainerStyle>

                  <Style TargetType="telerik:RadComboBoxItem">

                      <Setter Property="Content" Value="{Binding Name}"/>

                      <Setter Property="ToolTip" Value="{Binding Id}"/>

                  </Style>

              </telerik:RadComboBox.ItemContainerStyle>           

          </telerik:RadComboBox>

      </Grid>

  
  I hope this will help solve your issue.

  Hi,
  
  Actually I am able to show the seleted value in the comboBox. It's not the problem what I am facing. Please see the attached image.
  I am not able to see the items in the Collection container of RadComboBox. Here Binding of the selectedValue is must for me. I can't remove that one from the xaml.
  Please look at this and provide me a solution. I tried to send a sample code. But I am not knowing how to send. Tell me how to send a sample code. If you require, then I will send it.
  
  
  Thanks & Regards
  K Siva Prakash.

  Hi Siva,
  
  Please, use either the DisplayMemberPath property or the Content property setter in the ItemContainerStyle. Using both results in your items not being shown.
  
  Try the following:
  

  <telerik:RadComboBox HorizontalAlignment="Center" 

                                            VerticalAlignment="Center"  

                                            Width="283" 

                                            ItemsSource="{Binding}"   

                                            DisplayMemberPath="Name"

                                            SelectedValuePath="Id" 

                                            SelectedValue="{Binding Path=SelectedItem, Mode=TwoWay}" 

                                            Margin="100,100">

              <telerik:RadComboBox.ItemContainerStyle>

                  <Style TargetType="telerik:RadComboBoxItem">                    

                      <Setter Property="ToolTip" Value="{Binding Id}"/>

                  </Style>

              </telerik:RadComboBox.ItemContainerStyle>

          </telerik:RadComboBox>

  
  I hope this will be helpful.
