i havent use the datagrid but i found this solution check if it work for you .. call the following function before binding records in datagrid Private Sub grid() 'Method to check Current Page Index of Datagrid while Editing and Deleting records from it. If Datagrid1.Items.Count Mod Datagrid1.PageSize = 1 And _ Datagrid1.CurrentPageIndex = Datagrid1.PageCount - 1 And _ Datagrid1.CurrentPageIndex 0 Then Datagrid1.CurrentPageIndex = Datagrid1.CurrentPageIndex - 1 End If End Sub

hi! diya i am already write that code. my problem is when i delete 2nd page or 3rd page... all records. that time error occured in runtime. that error message is  Invalid CurrentPageIndex value. It must be >= 0 and this occur in this line datagrid1.databind(). i think this is enough to explain my problem. please give a proper code. Thanks.

hi.. if you r using code behind then add two events of datagrid this way protected void GridView1_PageIndexChanging(object sender GridViewPageEventArgs e) { GridView1.PageIndex = e.NewPageIndex; GridView1.DataBind(); } protected void GridView1_PageIndexChanged(object sender EventArgs e) { GridView1.DataBind(); }
