Hi,

The Edit Command is actually too early an event to access the EditForm controls, since the edit form will not be rendered then. Instead you can try accessing the controls in the ItemDataBound event of the grid as shown:
c#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridEditFormItem && e.Item.IsInEditMode)
        {
            GridEditFormItem item = (GridEditFormItem)e.Item;
            RadGrid grid = (RadGrid)item.FindControl("RadGrid2");

        }
    }

Thanks
Princy.
