在GridView + Asp.net中排序

Question

如何在網格視圖中執行排序？

請幫忙

Answer 1

您可以實現類似下面的代碼：

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; 
} 

有了這個代碼，你的GridView的定義應爲：

<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

不知道你是否已經在你的代碼中添加了事件或不在你身後。

您有爲GridView設置的AllowSorting="true"，因此您需要 爲其排序事件設置了事件處理程序。

< 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 

}
