Hello Kannadasan,

I guess you want to format the SelectedDate shown in RadDatePicker when the grid in edit mode. If so, the following code will help you to achieve this.

C#:

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
    {
        if (e.Item is GridEditFormItem && e.Item.IsInEditMode)
        {
            GridEditFormItem edititem = (GridEditFormItem)e.Item;
            RadDateTimePicker pick = (RadDateTimePicker)edititem["actiondate"].Controls[0];
            pick.DateInput.DisplayDateFormat = "MMM-dd-yyyy h:mm tt";
        }
    }

Thanks,
Princy.
