AutoGenerateColumns

[Guest]

Hi:

I'm using the DataGrid control with its AutoGenerateColumns property set to
"true". However, I want to programatically change the HeaderText of one its
colums. Nothing I've tried including putting the code in ItemDataBound seem
to be working. Here's what I tried:
Datagrid1.Columns(7).HeaderText = "Reward " & Application("ShowPoints")

I get an "index out of range" exception when this code runs. There are more
than 8 columns in DataGrid1.

Please help.

Thanks,

Jibey

Your only chance to catch column headers for autogenerated columns is the
ItemCreated event.

Hi:

That doesn't work either. Here's the code I wrote
Sub DataGrid_ItemCreated(ByVal sender As Object, ByVal e As
DataGridItemEventArgs)
If ddlReport.SelectedValue = "Claim Details" Then
Datagrid1.Columns(7).HeaderText = "Reward " &
Application("ShowPoints")
End If
End Sub

I still get an index out of range error.

The Columns doesn't include autogenerated columns.

The whole point of the event is to catch items while they are created. That
is e.Item. You can tell the header items by looking at e.Item.ItemType
property. You can change the header text as e.Item.Cells.Text =
"meHeader";

That works. However, the sort functionality is disabled. I had set the
AllowSorting property of the grid to true. When I change the names of the
headings this way, they do not have a link button. They just show up as text
that cannot be clicked for sorting. The olther columns where I'm not setting
the headings this way do allow sorting.

Is there a way around this?

Try something like
((LinkButton)e.Item.Cells.Controls[0]).Text = "foo";

If it doesn't work, place breakpoints there and take a look at
e.Item.Cells, I'm quite sure you will find Controls collection there and
then just play with that. Its horrible, its ugly, but it works.
