C# asp.net中gridview列的排序

我有一个从数据库加载数据的gridview。数据第一次按日期时间排序显示在gridview中。在gridview的一列上，我希望允许排序，例如在main_post列上。我已经尝试过了，但是当我单击列的标题时，gridview仍然没有排序

这是我的gridview前端代码：

<asp:DataGrid ID="Datagrid1" runat="server" 
    AllowPaging="True" 
    AllowSorting="True" 
    OnSorting="ComponentGridView_Sorting">
    <Columns>
        <asp:BoundColumn DataField="main_post" HeaderText="Header Post ID" 
            SortExpression="ComponentGridView_Sorting" />
    </Columns>
</asp:DataGrid>

我没有任何错误，我也不知道我的错误在哪里，有人能帮我解决这个问题吗

提前谢谢。

我得到了解决方案。希望这能帮助其他面临类似问题的人。在.aspx页面上，需要更改：

从

OnSorting=“ComponentGridView\u排序”

到

onsortcommand=“ComponentGridView\u排序”

然后将此代码放在aspx.cs上（后端代码）：

简单，将Allowsorting属性设置为true，并在gridview中添加排序事件

不要紧张，这真的太容易了，按照我的步骤去做

步骤1创建GridView

 <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" AllowPaging="true"  class="w3-table-all"
        OnPageIndexChanging="OnPageIndexChanging" PageSize="20" >
        <Columns>
            <asp:BoundField HeaderStyle-CssClass="w3-blue" ItemStyle-CssClass="w3-hover-green" ItemStyle-Width="250px" DataField="sn_no" HeaderText="ID" />
            <asp:BoundField HeaderStyle-CssClass="w3-blue" ItemStyle-CssClass="w3-hover-green" ItemStyle-Width="500px" DataField="name" HeaderText="Name" />
            <asp:BoundField HeaderStyle-CssClass="w3-blue" ItemStyle-CssClass="w3-hover-green" ItemStyle-Width="500px" DataField="mo" HeaderText="Mobile" />
            <asp:BoundField HeaderStyle-CssClass="w3-blue" ItemStyle-CssClass="w3-hover-green" ItemStyle-Width="500px" DataField="email" HeaderText="Email Id" />
            <asp:BoundField HeaderStyle-CssClass="w3-blue" ItemStyle-CssClass="w3-hover-green" ItemStyle-Width="500px" DataField="loc" HeaderText="Location" />
            <asp:BoundField HeaderStyle-CssClass="w3-blue" ItemStyle-CssClass="w3-hover-green" ItemStyle-Width="500px" DataField="date" HeaderText="Date" />
            <asp:BoundField HeaderStyle-CssClass="w3-blue" ItemStyle-CssClass="w3-hover-green" ItemStyle-Width="500px" DataField="day2" HeaderText="Day" />
            <asp:BoundField HeaderStyle-CssClass="w3-blue" ItemStyle-CssClass="w3-hover-green" ItemStyle-Width="500px" DataField="date" HeaderText="Date" />
            <asp:BoundField HeaderStyle-CssClass="w3-blue" ItemStyle-CssClass="w3-hover-green" ItemStyle-Width="500px" DataField="time" HeaderText="Time" />
        </Columns>

  </asp:GridView>

b） 。升序

cmd = new MySqlCommand("SELECT * FROM appointment ORDER BY sn_no DESC", con);

cmd = new MySqlCommand("SELECT * FROM appointment ORDER BY sn_no ASC", con);
