c# - GridView触发了未处理的事件PageIndexChanging

我已经允许分页并添加了下面的代码，但得到了错误。有人知道会有什么问题吗？
代码：

  protected void SubmitAppraisalGrid_SelectedIndexChanging(object sender, GridViewSelectEventArgs e)
    {
        SubmitAppraisalGrid.PageIndex = e.NewSelectedIndex;
        SubmitAppraisalGrid.DataBind();

    }

设计：

<asp:GridView ID="SubmitAppraisalGrid" runat="server"
                AutoGenerateColumns="False" BorderWidth="0px"
                onrowcreated="SubmitAppraisalGrid_RowCreated" ShowHeader="False"
                style="margin-right: 0px" AllowPaging="True" PageSize="1"
                onselectedindexchanging="SubmitAppraisalGrid_SelectedIndexChanging">
               </asp:GridView>

最佳答案

如果已将gridviews allowpaging属性设置为“true”，并且未处理PageIndexChanging事件，则会引发此错误。
要使用分页，请将PageIndexChanging事件处理程序添加到网格中，并将标记和代码更改为：

<asp:GridView ID="SubmitAppraisalGrid" runat="server"
                AutoGenerateColumns="False" BorderWidth="0px"
                onrowcreated="SubmitAppraisalGrid_RowCreated" ShowHeader="False"
                style="margin-right: 0px" AllowPaging="True" PageSize="1"
                onselectedindexchanging="SubmitAppraisalGrid_SelectedIndexChanging"
                OnPageIndexChanging="SubmitAppraisalGrid_PageIndexChanging">
               </asp:GridView>

//

protected void gvList_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
    SubmitAppraisalGrid.PageIndex = e.NewPageIndex;
    SubmitAppraisalGrid.DataBind();

    //bindGrid();
    //SubmitAppraisalGrid.PageIndex = e.NewPageIndex;
    //SubmitAppraisalGrid.DataBind();
}

protected void SubmitAppraisalGrid_SelectedIndexChanging(object sender, GridViewSelectEventArgs e)
{
   /// you selected index related logic here.
}

以编程方式设置PageIndex属性时不会引发此事件。
