datagrid分页问题

[sjzwinfor]

大家帮我看看这个代码，为什么分页后点下一页没有反应

string sqlstr="select * from WLKC where KCLB='ZBZS'";


dp=new OleDbDataAdapter(sqlstr,myConnection) ;

bind ();

//保存为Session

this.DataGrid1.DataBind();

}
catch

}

private void DataGrid1_PageIndexChanged(object source, System.Web.UI.WebControls.DataGridPageChangedEventArgs e)

}






}
}

这样试试：
Page_Load事件这样写：
private void Page_Load(object sender, System.EventArgs e)
{
if(!Page.IsPostBack)
{
bind ();
}
}

然后，bind()这样写：
public void bind()
{

try
{
string connstr = ConfigurationSettings.AppSettings ["wlkcdb"].ToString ();
myConnection = new OleDbConnection(ConfigurationSettings.AppSettings ["wlkcdb"].ToString ());

string sqlstr="select * from WLKC where KCLB='ZBZS'";

dp=new OleDbDataAdapter(sqlstr,myConnection) ;
this.myConnection.Open();
dp.Fill(ds,"wlkc");//传递给“网络课程”表
this.DataGrid1.DataSource = ds.Tables[0].DefaultView;
this.DataGrid1.DataBind();
this.myConnection.Close();

}
catch
{
Response.Redirect ("database-error.htm");
}

}

在private void InitializeComponent()里
加入this.DataGrid1.PageIndexChanged += new System.Web.UI.WebControls.DataGridPageChangedEventHandler(this.DataGrid1_PageIndexChanged);

恩,在你的region设计器代码里好象没有看到分页事件的注册啊.
在下面的事件里加上:---------this.DataGrid1.PageIndexChanged += new System.Web.UI.WebControls.DataGridPageChangedEventHandler(this.DataGrid1_PageIndexChanged);
--------------------------------------------------------------------------
private void InitializeComponent()
{
this.ds = new System.Data.DataSet();
((System.ComponentModel.ISupportInitialize)(this.ds)).BeginInit();
//
// ds
//
this.ds.DataSetName = "NewDataSet";
this.ds.Locale = new System.Globalization.CultureInfo("zh-CN");
this.Load += new System.EventHandler(this.Page_Load);
((System.ComponentModel.ISupportInitialize)(this.ds)).EndInit();

}

freexin(小昕)你好，加入后，点下一页会跳到database-error.htm
