I'm using a hyperlink on a crystal report within Business Objects to lanuch my ASP.NET 1.1 page with a DataGrid.
The datagrid is using the embedded Edit, Update, Cancel and paging options.

Everything goes fine, ie, paging, editing, update, etc., until they get the following error from the DataGrid_UpdateCommand function: "Invalid CurrentPageIndex value. It must be >= 0 and < the PageCount." I'm unable to reproduce the error, and since we log errors into our database and get emailed when things go wrong, so I know people are receiving this error.

I've disabled the browser Back button, and this has reduced the number of times we get the error, but we still get it.

What would be causing the error?

Should I just direct people to page one of the grid when they get error?

Help.

when u r getting error??? i mean on click of link or on pageload?

I have seen this. It happens when they begin to page through their records and, if i remember correctly, it has to do with when you call the databind on the table you are paging through. Typically in a PageIndexChanged event handler you want to set the page index of the grid and then rebind it.

I use paging extensively on a few enterprise applications and I have never had a problem with that particular porition of the gird.

I will only tell you how to do it, not do it for you.
Unless, of course, you want to hire me to do work for you.

Did you assign your datasource to Session when you initially got your data source that way when you page through you wont have any problems.
ex.
private void prevPolicyDataGrid_PageIndexChanged(object source,System.Web.UI.WebControls.DataGridPageChang edEventArgs e)
{

    DataTable policyDT = (DataTable)Session["policyHistoryDT"];
    prevPolicyDataGrid.DataSource= policyDT;
    prevPolicyDataGrid.CurrentPageIndex = e.NewPageIndex;
    prevPolicyDataGrid.DataBind();
}
