上面的程式碼中關鍵的程式碼是：
protected void GridView1_Sorting(object sender, GridViewSortEventArgs e)
{
string sortExpression = e.SortExpression;
if (GridViewSortDirection == SortDirection.Ascending) //設定排序方向
{
GridViewSortDirection = SortDirection.Descending;
SortGridView(sortExpression, " DESC");
}
else
{
GridViewSortDirection = SortDirection.Ascending;
SortGridView(sortExpression, " ASC");
}
}
private void SortGridView(string sortExpression, string direction)
{
string Orgid = Request["orgid"].ToString();
DataTable dt_BuildingMrShort = BLL_crops.BLL_TQ.p_TQ_MRShort_Building(System.DateTime.Now.Year, int.Parse(Orgid));
DataView dv = new DataView(dt_BuildingMrShort);
dv.Sort = sortExpression + direction;
this.GridView1.DataSource = dv;
this.GridView1.DataBind();
}
public SortDirection GridViewSortDirection
{
get
{
if (ViewState["sortDirection"] == null)
ViewState["sortDirection"] = SortDirection.Ascending;
return (SortDirection)ViewState["sortDirection"];
}
set { ViewState["sortDirection"] = value; }
}
