推荐答案

尝试以下一项:

Try this one:

private const string ASCENDING = " ASC";
private const string DESCENDING = " DESC";

public SortDirection GridViewSortDirection
{
    get
    {
        if (ViewState["sortDirection"] == null)
            ViewState["sortDirection"] = SortDirection.Ascending;

        return (SortDirection) ViewState["sortDirection"];                
    }
    set { ViewState["sortDirection"] = value; } 
}

protected void GridView_Sorting(object sender, GridViewSortEventArgs e)
{
    string sortExpression = e.SortExpression;

    if (GridViewSortDirection == SortDirection.Ascending)
    {
        GridViewSortDirection = SortDirection.Descending;
        SortGridView(sortExpression, DESCENDING);
    }
    else
    {
        GridViewSortDirection = SortDirection.Ascending;
        SortGridView(sortExpression, ASCENDING); 
    }   

}

private void SortGridView(string sortExpression,string direction)
{
    //  You can cache the DataTable for improving performance
    DataTable dt = GetData().Tables[0]; 

    DataView dv = new DataView(dt); 
    dv.Sort = sortExpression + direction;         

    GridView1.DataSource = dv;
    GridView1.DataBind();         
}

另外，添加SortExpression =< value here =">"在客户端脚本中，并且AllowSorting = True到您的gridview属性.

also, add SortExpression="<value here="">" in your client side script and AllowSorting=True to your gridview property.

对自身的查询中的gridview数据进行排序，并在页面加载事件中加载gridview.

希望对我有帮助

sort the gridview data in its query it self and load the gridview in page load event.

Hpoe this helps

我认为Eduard Lu做到了，我们有相同的解决方案，而且效果很好，我想这就是您所需要的，

希望对您有帮助！

谢谢，
