在GridView控件+ Asp.net排序

Question

我应该怎么做以执行在网格视图排序

请帮助

Answer 1

可以实现如以下代码：

protected void GridView1_Sorting(object sender, GridViewSortEventArgs e)
{
     DataTable dataTable = GridView1.DataSource as DataTable;

     if (dataTable != null)
     {
          DataView dataView = new DataView(dataTable);
          dataView.Sort = e.SortExpression + " " + ConvertSortDirectionToSql(e.SortDirection);

          GridView1.DataSource = dataView;
          GridView1.DataBind();
     }
}

private string ConvertSortDirectionToSql(SortDirection sortDirection)
{
     string newSortDirection = String.Empty;

     switch (sortDirection)
     {
          case SortDirection.Ascending:
              newSortDirection = "ASC";
          break;

          case SortDirection.Descending:
              newSortDirection = "DESC";
          break;
     }

     return newSortDirection;
}

使用这个代码，你的GridView定义应为：

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" AllowSorting="true" OnSorting="GridView1_Sorting">
<Columns>
    <asp:BoundField DataField="Name" HeaderText="People Names" SortExpression="Name" />
    <asp:BoundField DataField="Age" HeaderText="People Ages" SortExpression="Age" />
</Columns>
</asp:GridView>

Answer 2

不知道你是否已经添加事件或没有后面的代码。

您必须为GridView AllowSorting="true"集，因此，你需要 具有事件处理程序的事件排序

< asp:GridView AllowSorting=true ID="GridView1" runat="server" 
  OnSorting="GridView1_Sorting" >
    ...
< /asp:GridView >


protected void GridView1_Sorting(object sender, GridViewSortEventArgs e)

{

     //Add your code here for handling

}
