GridView SubHeaders

Hi,
I added subheaders to gridview same way as they did in the  below link.
http://www.carlj.ca/2008/04/20/adding-or-inserting-subheader-rows-into-a-gridview/
Please check the above link.
I have two grids on the form.The grids have edit command button.When I click on the edit command in one of the grids the sub headers in the 2nd grid got disappearing.

How can the  subheaders remain stayed in 2nd grid while editing the 1st grid.
Please let me know.

Thanks

The article does not address the issue of editing a GridView that has custom sub-headers, but generally it's a matter of re-binding the GridView in the RowEditing event after handling the edit. This would cause the RowDataBound event to run again, which would restore your sub-headers. Referring to the article, you would need to write this inside the RowEditing event after handling the edit:

        this.gdvRestaurants.DataSource = GetRestaurants();
        this.gdvRestaurants.DataBind();
