Hi Jaya,

You can use the CellEditorInitialized event to access the editor and change the default context menu. Here is a complete example of this:
RadContextMenu myMenu = new RadContextMenu();
public RadForm1()
{
    InitializeComponent();
    for (int i = 0; i < 5; i++)
    {
        myMenu.Items.Add(new RadMenuItem("Item" + i));
    }
    radGridView1.DataSource = GetTable();
    radGridView1.CellEditorInitialized += RadGridView1_CellEditorInitialized;
}
 
private void RadGridView1_CellEditorInitialized(object sender, Telerik.WinControls.UI.GridViewCellEventArgs e)
{
    var editor = e.ActiveEditor as RadTextBoxEditor;
    if (editor != null)
    {
        var element = editor.EditorElement as RadTextBoxEditorElement;
        element.TextBoxItem.HostedControl.ContextMenu = new ContextMenu();
        element.TextBoxItem.HostedControl.MouseDown -= TextBoxItem_MouseDown;
        element.TextBoxItem.HostedControl.MouseDown += TextBoxItem_MouseDown;
    }
}
 
private void TextBoxItem_MouseDown(object sender, MouseEventArgs e)
{
    var textbox = sender as Control;
    myMenu.Show(textbox, e.Location);
}

I hope this will be useful. Let me know if you have additional questions.
