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:
- 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.
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.
- Canceling AutoGeneratingColumn event for a particular column.
Example 2: Canceling adding a column in AutoGeneratingColumn event
private void clubsGrid_AutoGeneratingColumn(object sender, GridViewAutoGeneratingColumnEventArgs e)
{
if (e.Column.UniqueName == "Players")
{
e.Cancel = true;
}
}
