Hi,

I am unable to disable the context menu of the radgrid. I built my own Menu and set the Property

        Me.RadGridView1.ContextMenuStrip = MyOwnContextMenu

Now it shows both, my own menu and the default menu (copy, sort ascending, etc). How can I hide / disable the default ?

Using :
    RadControls for WinForms Q1/2008
    VB.Net

Greetings

RadGridView Load Time, and Filtering with DateTime

Hi,
After migrating all DataGridView to RadGridView, I have other question:

When the form using RadGridView first viewed, the UI freeze quite long (I'm tested in my P4 machine about 3-5 sec) before showed. Is there any method/trick to pre-load RadGridView say when I showing splash screen, so the delay wont happen.
I have field DateTime type, when I enable filtering and enter filter value it's was ok, but how to clear the filter value ?
How to alter Group Text, as far I known it was value of ColumnHeader Caption or Column FieldName.

Best Regards,
Fakhru Rahman

            // set datasource  
        
            cbTest.SuspendLayout();  
        
            cbTest.DataSource = Enum.GetNames(typeof(ExportTypes));  
        
            cbTest.SelectedIndex = 0;
