[Solved] Display all the columns header of a radgridview in a listbox of raddropdownbutton to allow users to choose which columns to display

I tried the following but it doesn't work.

 

<Window x:Class="WpfApplication1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <Grid.ColumnsDefinitions>
            <ColumnsDefinition Height="Auto" />
            <ColumnsDefinition Height="50" />
            <ColumnsDefinition />
        </Grid.ColumnsDefinitions>
<telerik:RadDropDownButton AutoOpenDelay="0:0:0.0" 
                           Content="Choose an Item"> 
    <telerik:RadDropDownButton.DropDownContent> 
        <ListBox ItemsSource="{Binding Columns, ElementName=RadGridView1}" Grid.Column="0">
            <ListBox.ItemTemplate>
                <DataTemplate>
                    <CheckBox Content="{Binding Header}" IsChecked="{Binding IsVisible, Mode=TwoWay}" />
                </DataTemplate>
            </ListBox.ItemTemplate>
        </ListBox>
    </telerik:RadDropDownButton.DropDownContent> 
</telerik:RadDropDownButton> 
        <telerik:RadGridView x:Name="RadGridView1" ItemsSource="{Binding View}" Grid.Column="1" />
    </Grid>
</Window>

Hi, I ran your project but nothing was shown on the mainwindow. Did I miss out something?

I see! Thanks!
