Gridview with multiple header rows - extra rows not being rendered


I have just installed the CSS Friendly Control Adapters and now my gridviews are not displaying dynamically added header rows.

Code for adding rows is like so:

Dim headerCell As New TableHeaderCell

headerCell.ColumnSpan = gridview.Columns.Count

headerCell.Text = heading

Dim rowHeader As New GridViewRow(0, -1, DataControlRowType.Header, DataControlRowState.Normal)


CType(gridview.Controls(0), Table).Rows.AddAt(0, rowHeader)


This is typically used for adding a nicely formatted heading row and it is a requirment that i must have this extra row. I sometimes need to add an additional row for sub grouping of columns.

I do this on the RowDataBound event.

Looking at the rendered source I do not see my rows anywhere however when doing an excel export (by passing the grid) I can see my rows however there is nothing in them.

I did try to search this forum for previous posts covering this issue but could not find anything, any help would be greatly appreciated. Thank You.

Just to verify i reflected the GridView class. It appears that only one header row can be rendered. However if you are looking to attach a row as an additional header, you would have to do it after the DataBind event and before the render.

I can whip up a code sample if you need one.

Hi, Thanks for the quick response. I am not sure i follow you though.

What I am asking is "I have been adding rows in the past without any issue but now after installing the adapters it no longer works"

Are you saying you have a solution for adding the extra rows when using the adapters? If so then yes a brief sample would be great.

I'm sorry, through my one blood shot eye, and lack of mountain dew, i missed the CSS adapter part, i apologize. Trying to recreate it, i have the same problem.
