Show/Hide Columns outside of RadGridView

This topic will show you how to choose which columns to be visible from outside of RadGridView.

There are several options available:

ListBox Outside RadGridView

The example will represent a ListBox and RadGridView. The ListBox will list the available columns for RadGridView and each of the items in this list will have a check box for determining the visibility of the column.

Here are the definitions of the controls.

<Grid Background="White"> 
    <Grid.ColumnDefinitions> 
        <ColumnDefinition Width="150"/> 
        <ColumnDefinition Width="*"/> 
    </Grid.ColumnDefinitions> 
    <ListBox /> 
    <telerik:RadGridView Grid.Column="1" 
                 Margin="10,0,0,0" /> 
</Grid> 
Next bind the ListBox.ItemsSource to RadGridView.Columns collection via Element Binding.

<Grid Background="White"> 
    <Grid.ColumnDefinitions> 
        <ColumnDefinition Width="150"/> 
        <ColumnDefinition Width="*"/> 
    </Grid.ColumnDefinitions> 
    <ListBox ItemsSource="{Binding Columns, ElementName=radGridView}" /> 
    <telerik:RadGridView x:Name="radGridView" 
                 Grid.Column="1"  
                 Margin="10,0,0,0" /> 
</Grid> 
After that define DataTemplate for ItemTemplate property of the ListBox. It should include a CheckBox and you can bind its IsChecked property to column.IsVisible property using TwoWay Data Binding.

<Grid Background="White"> 
    <Grid.ColumnDefinitions> 
        <ColumnDefinition Width="150"/> 
        <ColumnDefinition Width="*"/> 
    </Grid.ColumnDefinitions> 
    <ListBox ItemsSource="{Binding Columns, ElementName=radGridView2}"> 
        <ListBox.ItemTemplate> 
            <DataTemplate> 
                <CheckBox Content="{Binding Header}" 
                  IsChecked="{Binding IsVisible, Mode=TwoWay}" /> 
            </DataTemplate> 
        </ListBox.ItemTemplate> 
    </ListBox> 
    <telerik:RadGridView x:Name="radGridView2" 
                 Grid.Column="1"  
                 Margin="10,0,0,0" /> 
</Grid> 
Provide RadGridView with an appropriate data source and run your application. The result should be similar to this snapshot: Rad Grid View radgridview how to column chooser 2

You can download a runnable project of the previous example from our online SDK repository: ColumnChooser.
