Hello Hasan,

You can access the UserControl and make changes to the controls inside the usercontrol in the ItemCreated event of the grid as the EditCommand is too early for the UserControl to be created. Check out the code below:
cs:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
    {

       if (e.Item is GridEditableItem && e.Item.IsInEditMode)
        {
            GridEditableItem editedItem = e.Item as GridEditableItem;
            UserControl userControl = (UserControl)e.Item.FindControl(GridEditFormItem.EditFormUserControlID);
            Button btn = (Button)userControl.FindControl("CancelButton");
            btn.Enabled=false;
        }
     }

Thanks
