Hello,

It is possible to totally customize the default editors.  You'll need to handle the static WebDataGrid event to initialize them.  This will initialize the default editors in the same way for any grid that uses them.  Here is the code you'll need.

protected void Page_Load(object sender, EventArgs e)
    {
        Infragistics.Web.UI.GridControls.WebDataGrid.InitializeDefaultEditors += new InitializeDefaultEditorsEventHandler(WebDataGrid_InitializeDefaultEditors);
    }

    void WebDataGrid_InitializeDefaultEditors(object sender, DefaultEditorsEventArgs e)
    {
        if (e.NumericEditor != null)
        {
            e.NumericEditor.Buttons.SpinOnArrowKeys = false;
        }
        if (e.DateTimeEditor != null)
        {
        }
    }

regards,

David Young
