how can I export ALL datagrid rows to excel?

[The Colonel]

I'm only getting current page. I've tried playing with the
PageSize and AllowPaging = False before exporting, but no luck. Here's
my code:

<snip>
Public Sub btnExport_OnClick(ByVal sender As Object, ByVal e As
EventArgs)
Response.ContentType = "application/vnd.ms-excel"
Response.AddHeader("Content-Disposition", "inline;filename=" &
gstrTableName & ".xls")
Response.Charset = ""
Me.EnableViewState = False
ClearControls(dgParent)
Dim tw As New System.IO.StringWriter
Dim hw As New System.Web.UI.HtmlTextWriter(tw)
' Get the HTML for the control.
dgParent.PageSize =
gobjDataSet.Tables(gstrTableName).Rows.Count
dgParent.RenderControl(hw)
' Write the HTML back to the browser.
Response.Write(tw.ToString())
' End the response.
Response.End()
End Sub
Private Sub ClearControls(ByVal control As Control)
Dim i As Integer
For i = control.Controls.Count - 1 To 0 Step -1
ClearControls(control.Controls(i))
Next
If Not TypeOf control Is TableCell Then
If Not (control.GetType().GetProperty("SelectedItem") Is
Nothing) Then
Dim literal As New LiteralControl
control.Parent.Controls.Add(literal)
Try
literal.Text =
CStr(control.GetType().GetProperty("SelectedItem") .GetValue(control,
Nothing))
Catch
End Try
control.Parent.Controls.Remove(control)
Else
If Not (control.GetType().GetProperty("Text") Is
Nothing) Then
Dim literal As New LiteralControl
control.Parent.Controls.Add(literal)
literal.Text =
CStr(control.GetType().GetProperty("Text").GetValu e(control, Nothing))
control.Parent.Controls.Remove(control)
End If
End If
End If
End Sub
</snip>

I guess Im too tired to really give much here, but the the first question is
why you are not using the object to which the DataGrid is bound to export
from, rather than the grid itself ?

I have an example of this on my website, www.aboutfortunate.com, (your code
is very close). Click on the "Code Library" link at the top of the page and
then click on the datagrid row "Ouput a datagrid as an excel spreadsheet
page".

Thanks Mr N. - what would that look like?

[The Colonel]

Thanks, Justin. It is very close - I guess the only difference is that
I'm displaying the grid with an export button, so the export is
actually taking place in an OnClick sub. I'll probably have to go a
different route.

Got it - I was turning off AllowPaging, but I needed to rebind after
that!
