如何让asp：GridView排序？

我有一个asp:GridView控制，我已经设置AllowSorting="True"属性上：如何让asp：GridView排序？

<asp:GridView ID="gridUsers" runat="server" PageSize="100" ShowHeaderWhenEmpty="True" 
    Width="100%" AllowSorting="True" onrowcreated="gridUsers_RowCreated" 
    onsorting="gridUsers_Sorting"> 
</asp:GridView>

在设计时，网格看起来排序：

但在运行时只有中间一列是可分拣：

如何在ASP.NET中对asp:GridView进行排序？

注意：该asp:GridView与AllowSorting需要一个Sorting事件处理程序存在：

protected void gridUsers_Sorting(object sender, GridViewSortEventArgs e) 
{ 
    //asp:GridView will throw an exception if a Sorting event handler isn't present 
}

更新：我意识到什么特别之处说明列。它是显示名称从数据库原样显示的唯一列，原样为。其余列i have to fix the display name to be presentable：

protected void gridUsers_RowCreated(object sender, GridViewRowEventArgs e) 
{ 
    e.Row.Cells[0].Visible = false; //UserGUID 
    e.Row.Cells[1].Text = "User name"; 
    e.Row.Cells[2].Text = "Full name"; 
    //3=Description 
    e.Row.Cells[4].Text = "E-mail"; 
    e.Row.Cells[5].Text = "Active"; 
     e.Row.Cells[5].Visible = false; 
    e.Row.Cells[6].Text = "Account type"; 
}

现在我只需要找出棘手的部分;并使列可以排序。

这个代码一定会帮助你：

在GridView，使属性AllowSorting = “true” 和GridView中的列给出这样

<asp:BoundField DataField="UserName" HeaderText="User Name" SortExpression="UserName" /> 
<asp:BoundField DataField="FullName" HeaderText="Full Name" SortExpression="FullName" />

并且还使用以下编码：

protected void gv_Sorting(object sender, GridViewSortEventArgs e) 
{ 
    try 
    { 
     string sortExpression = e.SortExpression; 
     ViewState["z_sortexpresion"] = e.SortExpression; 
     if (GridViewSortDirection == SortDirection.Ascending) 
     { 
      GridViewSortDirection = SortDirection.Descending; 
      SortGridView(sortExpression, "DESC"); 
     } 
     else 
     { 
      GridViewSortDirection = SortDirection.Ascending; 
      SortGridView(sortExpression, "ASC"); 
     } 
    } 
    catch (Exception ex) 
    { 
     return ex.Message.ToString(); 
    } 
} 
public SortDirection GridViewSortDirection 
{ 
    get 
    { 
     if (ViewState["sortDirection"] == null) 
      ViewState["sortDirection"] = SortDirection.Ascending; 
     return (SortDirection)ViewState["sortDirection"]; 
    } 
    set 
    { 
     ViewState["sortDirection"] = value; 
    } 

} 
private void SortGridView(string sortExpression, string direction) 
{ 
    DTSorting = new DataView(DTSorting, "", sortExpression + " " + direction, DataViewRowState.CurrentRows).ToTable(); 
    gv.DataSource = DTSorting; 
    gv.DataBind(); 
} 
public DataTable DTSorting 
{ 
    get 
    { 
     if (ViewState["Sorting"] != null) 
     { 
      return (DataTable)ViewState["Sorting"]; 
     } 
     else 
      return null; 
    } 
    set 
    { 
     ViewState["Sorting"] = value; 
    } 
}

这里，考虑“DTSorting”是您绑定GridView“gv”的DataTable。

我不得不重新设计所有使用“早期”绑定，而不是“迟到”绑定（因此在答案中使用'asp：BoundField'）。 GridView扼流器如果在运行时绑定它。 –

protected void gridUsers_Sorting(object sender, GridViewSortEventArgs e) 
{ 
    DataTable dt = Session["SortedTable"] as DataTable; 

    if (dt != null) 
    { 

     //Sort the data. 
     dt.DefaultView.Sort = e.SortExpression + " " + GetSortDirection(e.SortExpression); 
     gridUsers.DataSource = Session["SortTable"]; 
     gridUsers.DataBind(); 
    } 
}

从这个msdn example改编：
