如何在gridview中使动态列标题可点击

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" OnRowDataBound="GridView1_RowDataBound">
    <Columns>
        <asp:TemplateField>
            <ItemTemplate>
                <asp:LinkButton ID="lnkColumnHeader" runat="server" Text='<%# Eval("ColumnName") %>' OnClick="lnkColumnHeader_Click"></asp:LinkButton>
            </ItemTemplate>
        </asp:TemplateField>
        <asp:BoundField DataField="Column1" HeaderText="Column 1" />
        <asp:BoundField DataField="Column2" HeaderText="Column 2" />
        <!-- 添加更多的动态列 -->
    </Columns>
</asp:GridView>

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        // 绑定数据源
        DataTable dt = GetDataSource();
        GridView1.DataSource = dt;
        GridView1.DataBind();
    }
}

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.Header)
    {
        // 设置动态列标题的LinkButton点击事件
        LinkButton lnkColumnHeader = (LinkButton)e.Row.FindControl("lnkColumnHeader");
        lnkColumnHeader.CommandArgument = "ColumnName"; // 设置命令参数，可以根据需要传递不同的参数
        lnkColumnHeader.Command += new CommandEventHandler(lnkColumnHeader_Click);
    }
}

protected void lnkColumnHeader_Click(object sender, CommandEventArgs e)
{
    // 处理动态列标题的点击事件
    string columnName = e.CommandArgument.ToString();
    // 根据需要执行相应的操作，例如对数据进行排序、筛选等
}
