Modify Datagrid HeaderTemplate through code

[Dave A.]

I have an editable datagrid with HeaderTemplates that have to be written
through code, with data from the database. I can only find code to add new
columns and modify text. Is there any way to be able to modify existing
HeaderTemplate.Text values?


thanks
Dave A.

You can do it once the row is created. I do this in a sample here (it's using
the 2.0 GridView, but the concept is same for v1.1 DataGrid):

How is this function called - _grid_RowDataBound(), and will I need to loop
through the HeaderTemplate row to modify the text? Instead of looping through
the whole row, can I refer to the column index?

Thanks for the tip. I modified your code for the datagrid. This is what worked.

<aspataGrid id="DGProducts"
runat="server"
Cellpadding="4" Cellspacing="0" Width="800"
BorderStyle="solid" BorderColor="black" BorderWidth="1"
AlternatingItemStyle-BackColor="palegoldenrod"
ItemStyle BackColor="beige"
HeaderStyle-CssClass="productsHead"
Font-Size="10"
AutoGenerateColumns="false"
OnEditCommand="DGProducts_Edit"
OnCancelCommand="DGProducts_Cancel"
OnUpdateCommand="DGProducts_Update"
OnItemDataBound="Item_Bound">


Public Sub Item_Bound(sender As Object, e As DataGridItemEventArgs)

Dim itemType As ListItemType
Dim intCell As TableCell

itemType = CType(e.Item.ItemType, ListItemType)

If (itemType = ListItemType.Header) Then
intCell = CType(e.Item.Controls(4), TableCell)
intCell.Text = "fy text"
End If
End Sub

thanks,
Dave A.

The DataGrid (again in 1.1, which is a bit different than my 2.0 sample)
has a ItemDataBound event. This will get called after each row (including
the the header) is full created and populated with data.
