绑定数据时Gridview分页中的错误 无法将类型为“ System.EventArgs”的对象转换为类型为“ System.Web.UI.WebControls.GridViewPageEventArgs”

我有一个数据绑定事件来动态添加标头。当页面首次加载时，它加载正常。但是当我尝试单击下一页时，它在数据绑定事件中出错

Protected Sub OnDataBoundlvs(sender As Object, e As EventArgs)
    Dim row As New GridViewRow(0, 0, DataControlRowType.Header, DataControlRowState.Normal)
    Dim cell As New TableHeaderCell()
    cell.Text = "Network"
    cell.ColumnSpan = 1
    cell.CssClass = "FrozenHeader"
    row.Controls.Add(cell)
End Sub

Protected Sub OnPaging3(sender As Object, e As GridViewPageEventArgs) Handles LVSGrid.PageIndexChanging
    LVSGrid.PageIndex = e.NewPageIndex
    LVSGrid.DataBind()
End Sub
