以上是我的Gridview表的代码。目前我的问题是我的排序没有正常工作。但是当它放在Updatepanel之外时，它正在工作。
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();
}
}
这是我的排序代码。任何帮助和建议将不胜感激。谢谢！

</form>根据上面的评论你提到你的命令参数是“名称”无法转换为整数..
根据以下代码轻松获取RowIndex
protected void GridView7Data_RowCommand(object sender, GridViewCommandEventArgs e)
{
int index = Convert.ToInt32(e.CommandArgument); // Error Converting
}
参考LinkButton，如下面的aspx html
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;
}
}
