How to reset CurrentPageIndex

I'm writing an asp.net app that allow the user to do a search and displays the
results inside a datagrid.

It gave me the 'Invalid CurrentPageIndex Calue. It must be >=0 and < the page
count' error.

Although I know WHY this error is appearing: the user searches, and then goes
through the pages of the datagrid results to, say, page 30. Then, he do another
search (without leaving the page or returning to page 1 of the datagrid
paging). If the 2nd search has <30 pages, it will generate this error, because
according to the app, the currentpageindex is still at 30.
Does anybody know how to refresh the datagrid so that each time the user
presses the Search button, the currentpageindex is sent back to 0?

Thanks

Ever get a resolution to this??

Anyone have any ideas how to programmatically set CurrentPageIndex using the
Dreamweaver controls on postback?

/*
* Check to see if this page was posted back, and if so was it due to a
dynamic drop down
* or to a page index change in the DataGrid? If it was due to a dynamic
drop down [I wanna see the 'volunteers' of a
* specific 'group'] then set the current page index back to 0, so we are on
the first page.
*/
protected override void OnPreRender(EventArgs e)
{
if(Page.IsPostBack)
{
if(Request.Form["__EVENTTARGET"] == "ddlVolSector")
{
// DOESNT WORK
dsVolunteers.CurrentPageIndex = 0;
// DOESNT WORK
dsVolunteers.CurrentPageIndex--;
// DOESNT WORK
DreamweaverCtrls.DataSet.CurrentPageIndex = 0;
}
}
}
