有关aspnetpager与datagrid合用的问题

Question

为什么我在点击datagrid的任何按钮时都会触发aspnetpager的PageChanged事件?
想只有翻页时触发此事件

Answer 1

private void InitializeComponent()
{    
this.txtEndDate.TextChanged += new System.EventHandler(this.txtEndDate_TextChanged);
this.btnSearchOrder.Click += new System.EventHandler(this.btnSearchOrder_Click);
this.dgOrders.CancelCommand += new System.Web.UI.WebControls.DataGridCommandEventHandler(this.dgOrders_CancelCommand);
this.dgOrders.EditCommand += new System.Web.UI.WebControls.DataGridCommandEventHandler(this.dgOrders_EditCommand);
this.dgOrders.UpdateCommand += new System.Web.UI.WebControls.DataGridCommandEventHandler(this.dgOrders_UpdateCommand);
this.dgOrders.DeleteCommand += new System.Web.UI.WebControls.DataGridCommandEventHandler(this.dgOrders_DeleteCommand);
this.dgOrders.ItemDataBound += new System.Web.UI.WebControls.DataGridItemEventHandler(this.dgOrders_ItemDataBound);
this.Load += new System.EventHandler(this.Page_Load);
this.thisPager.PageChanged+=new Wuqi.Webdiyer.PageChangedEventHandler(thisPager_PageChanged);
}
private void Page_Load(object sender, System.EventArgs e)
{
if(!this.IsPostBack)
{
BindDate("","OrderId desc",thisPager.CurrentPageIndex,thisPager.PageSize);//
AddCustomText();
}

}private void thisPager_PageChanged(object src, Wuqi.Webdiyer.PageChangedEventArgs e)
{
thisPager.CurrentPageIndex=e.NewPageIndex;

this.BindDate(Session["whereClause"].ToString(),"OrderId desc",thisPager.CurrentPageIndex,thisPager.PageSize);
// ViewState["source"]=orders;
AddCustomText();
}
private void BindDate(string whereClause,string orderBy,int start,int pageLength)
{
int count;
OrdersCollection orders =Data.OrdersProvider.GetPaged(whereClause,orderBy,start,pageLength, out count);
Session["whereClause"]=whereClause;
if(orders!=null)
{
ViewState["source"]=orders;
}
thisPager.RecordCount=count;
//datagrid数据绑定
dgOrders.DataSource=ViewState["source"];
dgOrders.DataKeyField="OrderId";
dgOrders.DataBind();
}
public void AddCustomText()
{
//动态设置用户自定义文本内容
thisPager.CustomInfoText+=" 总页数：<font color=\"blue\"><b>"+thisPager.PageCount.ToString()+"</b></font>&nbsp;";
}

上面倒不是大问题,还有一个问题就是,每次翻页都会执行!ispostback下的语句,谁碰到过类似情况,帮忙解释下,谢谢.
