Prevent Column Auto-Generation

As you know, if AutoGenerateColumns="True" (which is by default), RadGridView creates a column for each property of the underlying business object. This article shows how to not auto generate a column for a specific property.

There are two ways to accomplish this:

1. Using DataAnnotations.

Apllying this approach you need to add a reference to the System.ComponentModel.DataAnnotations assembly and mark your property with [Display(AutoGenerateField = false)] attribute.

Example 1: Using DataAnnotations.

• C#

private ObservableCollection<Player> players; 
 
[Display(AutoGenerateField = false)] 
public ObservableCollection<Player> Players 
{ 
    get 
    { 
        if (null == this.players) 
        { 
            this.players = new ObservableCollection<Player>(); 
        } 
        return this.players; 
    } 
} 

Now, RadGridView will not generate a column for the Players property.

1. Canceling AutoGeneratingColumn event for a particular column.

Example 2: Canceling adding a column in AutoGeneratingColumn event

• C#

private void clubsGrid_AutoGeneratingColumn(object sender, GridViewAutoGeneratingColumnEventArgs e) 
{ 
    if (e.Column.UniqueName == "Players") 
    { 
        e.Cancel = true; 
    } 
}
