CurrentPageIndex

[acidrain9]

i have a page set up with a datagrid and two dropdown boxes
the datgrid is set to show 15 records and display paging at the bottom

sometimes (not always) when i select an item in the drop down box it brings me
to a page that says "Invalid CurrentPageIndex value. It must be >= 0 and < the
PageCount"

when i search my source code i don't find anything that states
"currentpageindex"

where is my problem and why does it not work all of the time?

i set up a quick javascript (posted below)

and it seems to work great no more errors

'<script runat="server">
'Sub Page_Load()
'LeadsGrid.CurrentPageIndex="0"
'End Sub
'</script>
