i have a dtagrid that take the source from a stored procedure acording to data in a dropdownlist
now my problem is that i tried to allow paging for the datagrid but when i'm in the third page i can't return to the second page it returns to the first page
my code is
in pageload With dg
            dg.AllowPaging = True
            dg.PagerStyle.Mode = PagerMode.NumericPages
            dg.PagerStyle.PageButtonCount = 2
            dg.PageSize = 2
            dg.DataSource = dsUpcour
            dg.ShowHeader = True
            dg.Visible = True
            dg.DataBind()
        End With
in Private Sub dg_PageIndexChanged(ByVal source As Object, _
 ByVal e As System.Web.UI.WebControls.DataGridPageChangedEvent Args) _
 Handles dg.PageIndexChanged
        dg.CurrentPageIndex = e.NewPageIndex
        dg.DataBind()
        dg.CurrentPageIndex = 0/*to avoid this error Invalid current pageIndex value. It must be >= 0 and < the PageCount. */

    End Sub

You are setting PageIndex = 0 ,that could be the reason.. or Check in store procedure for the start and end values to fetch the records.

thank you, but can you explain more please

You are using dsUpcour stored procedure to bind the Values to the Grid.For each page,you might be fetching only the set of records from the database.Like if you showing 10 records per page,you might have written to fetch 1(start) to 10(end) records for first page and for second page 11 to 20.. I was asking you to check whether you have manipulated correctly for start and end.

If you still didnt find solution check out the samples in this link..

thanks alote but i think that i have to apply the custom paging instead of default becouse the data source is a stored procedure
