我的页面中有一个gridview，它允许分页但是当我点击下一个数字时它会给我这个错误：System.Web.HttpException：GridView'GridView1'触发了未处理的事件PageIndexChanging。 我不知道如何解决它，我必须解决它，直到明天我真的需要帮助

答案 0 :(得分：1)
首先，您需要处理GridView PageIndexChanging事件，然后将新的PageIndex设置为GridView
<asp:GridView ID="GridView1" runat="server" AllowPaging="True" CellPadding="4"
DataKeyNames="idFromUsers" AutoGenerateColumns="False" ForeColor="#333333"
GridLines="None" onrowcommand="GridView1_RowCommand"
OnPageIndexChanging="GridView1_PageIndexChanging">
在Code Behind中添加此事件
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
GridView1.PageIndex = e.NewPageIndex;
GridView1.DataBind();
}
答案 1 :(得分：0)
因为您没有OnPageIndexChanging =“gridView_PageIndexChanging”事件。
protected void gridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
gridView.PageIndex = e.NewPageIndex;
gridView.DataBind();
}
