上面是我的Gridview表的代码。 目前，我的问题是我的排序工作不正常。 但是，将其放置在Updatepanel之外时，它可以工作。
protected void GridView7_Sorting(object sender, GridViewSortEventArgs e)
{
DataTable dtResult = (DataTable)ViewState["dt"];
if (dtResult.Rows.Count > 0)
{
if (Convert.ToString(ViewState["Sort"]) == "Asc")
{
dtResult.DefaultView.Sort = e.SortExpression + " Desc";
//ViewState["sort"] == "Desc";
}
else
{
dtResult.DefaultView.Sort = e.SortExpression + " Asc";
//ViewState["sort"] == "Asc";
}
GridView7.DataSource = dtResult;
GridView7.DataBind();
}
}
这是我进行排序的代码。 任何帮助和建议，将不胜感激。 谢谢！

我相信您的错误将是这条线...
protected void GridView7Data_RowCommand(object sender, GridViewCommandEventArgs e)
{
int index = Convert.ToInt32(e.CommandArgument); // Error Converting
}
根据上面的注释，您提到您的命令参数为“名称”，不能转换为整数。
根据以下代码轻松获取RowIndex的简便方法
protected void gv_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "xxx")
{
// Why LinkButton because your button type is LinkButton...
GridViewRow gvr = ((LinkButton)e.CommandSource).NamingContainer as LinkButton;
int rowIndex = gvr.RowIndex;
}
}
aspx html下方的LinkButton参考
<asp:LinkButton ID="lnkDownload7" runat="server" CommandArgument='<%# Eval("DetailsId") %>'
OnClick="DownloadFile7" Text="Download"></asp:LinkButton>
带有GridView和Progressbar的UpdatePanel无法正常工作
