     onselectedindexchanged="GridView1_SelectedIndexChanged" 
     GridLines="Vertical" onrowediting="GridView1_RowEditing" 
     onrowcancelingedit="GridView1_RowCancelingEdit"

排序不起作用。我錯過了什麼？

Answer 1

在排序事件處理程序中，您可以更改數據表的排序屬性。

dt.DefaultView.Sort = e.SortExpression + " ASC"; 
    gv.DataSource = dt; 
    gv.DataBind();
