我有一个启用了分页和排序的 GridView Web 控件。我已将数据源绑定到 SqlDataSource。当我尝试更改页面索引或排序时，出现“GridView 触发事件 [Sorting/PageIndexChanging] 未处理”错误。 SqlDataSource 不是已经具备处理这些事件的能力了吗？

隐藏代码
SqlDataSource sqlData = new SqlDataSource("Hidden for security reasons");
Select(DataSourceSelectArguments.Empty);
dataTbl.DataSource = sqlData;
dataTbl.DataBind();
headerTbl.Rows.Add(new TableRow());
你必须重新绑定
GridViewprivate void BindData()
{
SqlDataSource sqlData = new SqlDataSource("Hidden for security reasons");
Select(DataSourceSelectArguments.Empty);
dataTbl.DataSource = sqlData;
dataTbl.DataBind();
headerTbl.Rows.Add(new TableRow());
}
protected void dataTbl_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
dataTbl.PageIndex = e.NewPageIndex;
BindData();
}
在标记中添加到
GridViewOnPageIndexChanging="dataTbl_PageIndexChanging"
应该可以。
