Checking the nth List item

[Purna]

I want to check the nth item of the ComboBox with CheckBox dynamically. How can this be achieved?

I tried the following and an exception is thrown

radCombo.Items(n).IsSelected = True

 

The XAML is as followed:

 <DataTemplate x:Key="CheckBoxItemTemplate">
            <CheckBox Content="{Binding RelativeSource={RelativeSource AncestorType=telerik:RadComboBoxItem}, Path=Content}" 
                      IsChecked="{Binding RelativeSource={RelativeSource AncestorType=telerik:RadComboBoxItem}, Path=IsSelected}" 
                      telerik:TouchManager.ShouldSuspendMousePromotion="True" Click="CheckBox_Click"/>
        </DataTemplate>

 

<telerik:RadComboBox Name="radCombo" Height="30" Canvas.Left="650" Canvas.Top="55" Width=" 200" Background="White" AllowMultipleSelection="True" EmptyText="Select "
                                         MultipleSelectionSeparator=","  IsReadOnly="True" ItemTemplate="{StaticResource CheckBoxItemTemplate}" >
                    </telerik:RadComboBox>

Hello Purna,

When using ItemTemplate you could set the TextSearch.TextPath property in order to indicate which is the searchable property and this property will be displayed as well when an item is selected.

I have created sample project which demonstrates how to implement checkbox in the template of the combo box items in order to select them. You can find the project attached to this reply.
