如果你在GridView控件上设置 AllowPaging="true" or AllowSorting="true" 而没有使用使用数据源控件 DataSource (i.e. SqlDataSource, ObjectDataSource),运行则会出现下列错误：
当你在GridView控件上单击下一页时：
The GridView 'GridViewID' fired event PageIndexChanging which wasn't handled.
当你点击排序时，则回出现：
The GridView 'GridViewID' fired event Sorting which wasn't handled.
如果你没有设置GridView的DataSourceID 的属性，你必须添加一个操作才可以排序及分页。。
点这里查看下面的例子
<%@ Page Language="C#" %>
<%@ Import Namespace="System.Data" %>
<%@ Import Namespace="System.Data.OleDb" %>
<script runat="server">
private void PopulatePublishersGridView()
{
string connectionString = AccessConnectionString();
OleDbConnection accessConnection = new OleDbConnection(connectionString);
string sqlQuery = "SELECT [PubID], [Name], [Company Name], [Address], [City], [State], [Zip], [Telephone], [Fax], [Comments] FROM Publishers ORDER BY [Name] ASC;";
OleDbCommand accessCommand = new OleDbCommand(sqlQuery, accessConnection);
OleDbDataAdapter publishersDataAdapter = new OleDbDataAdapter(accessCommand);
DataTable publishersDataTable = new DataTable("Publishers");
publishersDataAdapter.Fill(publishersDataTable);
int dataTableRowCount = publishersDataTable.Rows.Count;
if (dataTableRowCount > 0)
{
gridViewPublishers.DataSource = publishersDataTable;
gridViewPublishers.DataBind();
}
}
private string AccessConnectionString()
{
string accessDatabasePath = Server.MapPath("~/App_Data/biblio.mdb");
return String.Format("Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};", accessDatabasePath);
}
private string GridViewSortDirection
{
get { return ViewState["SortDirection"] as string ?? "ASC"; }
set { ViewState["SortDirection"] = value; }
}
private string GridViewSortExpression
{
get { return ViewState["SortExpression"] as string ?? string.Empty; }
set { ViewState["SortExpression"] = value; }
}
private string GetSortDirection()
{
switch (GridViewSortDirection)
{
case "ASC":
GridViewSortDirection = "DESC";
break;
&nbs
