Asp.net 如何使asp:GridView可排序？

我有一个

asp:GridView

控件，我已经在该控件上设置了

AllowSorting=“True”

属性：

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

更新：我意识到了描述栏的特殊之处。它是数据库中唯一显示名称正确的列。其余各栏：

现在，我只需要找出棘手的部分；并使列可排序

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();
    }
}

---

改编自此：

此代码肯定会帮助您：

在GridView中，将属性AllowSorting=“True”设置为，并在GridView列中给出如下内容

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

这里，考虑“DTS排序”是绑定GRIDVIEW“GV”的DATABATE。

我必须重新设计所有的东西来使用“早期”绑定，而不是“迟”绑定（因此在代码中使用<代码> ASP：BoundField < /代码>）。如果在运行时绑定GridView，它将阻塞。

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();
    }
}

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

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;
    }
}
