Subheaders in Datagrid?

Hi all,

Is it possible to create subheaders in datagrids? Or rather to add a parent
header row to an existing datagrid? Currently my DG looks like this:

NAME | A - PART1 | A - PART2 | A - PART3 | B - PART1 | B - PART2

whereas id like it to look like:

NAME | A | B |
|PART1 | PART2 | PART3| PART1 | PART2|

or

| A | B
|
NAME |PART1 | PART2 | PART3| PART1 | PART2|

Im trying to intercept the databind event and checking for item type =
header, but am getting a bit stuck after that. IS that the correct approach,
or is there another way?

Thanks!

Something like this will work:

Private Sub GrdName_PreRend er(ByVal sender As Object, ByVal e As
System.EventArg s) Handles GrdName.PreRend er
'Add header to datagrid
Dim dgitem As New DataGridItem(0, 0, ListItemType.He ader)
Dim mycell As New TableCell
mycell.Text = ""
mycell.BackColo r = Color.White
dgitem.Cells.Ad d(mycell)
GrdName.Control s(0).Controls.A ddAt(0, dgitem)
End Sub

john,

that worked great - thanks!

a few things - tablecell.colum nspan allows you to set how "wide" the header
row will be and it may be a better idea to use the tableheadercell rather
than the normal tablecell.

Thanks. I do use columnspan and tableheadercell depending on the situation.
I was just giving a very simple example for demonstration purposes. Glad it
helped!

Hi All I have been trying to add a control to the header cell of a datagrid on my ASP.NET page. These controls are defined in the HTML as ASP.NET web controls. They are being added into the header of the datagrid in the "ItemDataBound" method of the grid. However, once, they are added in the grid, i seem to lose the event handler for the same control. Is there anyone who has tried this before and knows why this is hapenning ??
