GridView的功能很强大，可以实现很多的功能，下面我讲下GridView自动排序的实现方法。
/// <summary>
/// GridView排序 /// </summary> /// <param name="sender"></param>
/// <param name="e"></param>
protected void GridView1_Sorting(object sender, GridViewSortEventArgs e) {
if (GridViewSortExpression.Equals(e.SortExpression))
{
GridViewSortExpression = e.SortExpression; if (GridViewSortDirection.Equals("ASC")) { GridViewSortDirection = "DESC"; this.GridView1.DataSource = SortDataTable(数据源, false);
} else if (GridViewSortDirection.Equals("DESC")) { GridViewSortDirection = "ASC"; this.GridView1.DataSource = SortDataTable(数据源, true); } else { GridViewSortDirection = "ASC"; this.GridView1.DataSource = SortDataTable(数据源, true); } } else { GridViewSortDirection = "ASC"; GridViewSortExpression = e.SortExpression; this.GridView1.DataSource = SortDataTable(数据源, true); } this.GridView1.DataBind(); } /// <summary> /// 排序，并保存排序结果 /// </summary> /// <param name="dataTable"></param> /// <param name="isPageIndexChanging"></param> /// <returns></returns> protected DataView SortDataTable(DataTable dataTable, bool isPageIndexChanging) { if (dataTable != null) { DataView dataView = new DataView(dataTable); if (GridViewSortExpression != string.Empty) { if (isPageIndexChanging) { dataView.Sort = string.Format("{0} {1}", GridViewSortExpression, "ASC"); } else { dataView.Sort = string.Format("{0} {1}", GridViewSortExpression, "DESC"); } //if (Session["FileListTable"] != null) // Session["FileListTable"] = GetDataTable(dataView); } return dataView; } else { return new DataView(); } }
