Hi Telerik Support,

I need a CheckBox on my column header for select/unselect all gridview items.
My case is, the RadGridView control is created programmatically and I create a  new class named MyCustomer for RadGridView datasource:

public class MyCutomer
{
    public bool Selected{get;set;}
    public string Name{get;set;}
    public string Company{get;set;}
}
Create RadGridView control:
RadGridView grid = new RadGridView()
{
....
};
 
List<MyCustomer> customers = new List<MyCustomer>();
for( int index=0;index<10;index++)
{
    customers.Add(New MyCustomer()
    {
        ....
    });
}
 
grid.ItemsSource = customers;

All cells of the first column (Selected) are created as a CheckBox but the header is not.
How can I create a CheckBox for my header?

Regards,
Aeroth Lin

Hello,

 Why not use GridViewSelectColumn directly similar to this demo?

Hi,

Thanks for the quick response !
I knew that demo but there's no xaml file in my case, I need to insert a GridViewSelectColumn or specify the first column as GridViewSelectColumn dynamically.
All controls on the layout are created dynamically, so I have no xaml files to design my layout at design time.
Any ideas?

Hi,

 You can create the column dynamically and add it to the columns collection.

Hi,
I forgot to set the SelectionMode(without this column header will be empty):

SelectionMode = System.Windows.Controls.SelectionMode.Extended

It works perfectly now, thanks for your kind help.
