DataGrid的使用心得且(附大量代码)

    8.为DataGrid控件添加分页事件

  在DataGrid控件标签中加入如下代码
  OnPageIndexChanged="DataGrid1_PageIndexChanged"
  在后台中加入如下代码
  ///<summary>
  ///响应分页事件
  ///</summary>
  ///<paramname="sender"></param>
  ///<paramname="e"></param>
  publicvoidDataGrid1_Page(Objectsender,DataGridPageChangedEventArgse)
  {
   DataGrid1.CurrentPageIndex=e.NewPageIndex;
   DataBind();
  }
 
     9.为DataGrid控件添加绑定事件,即在DataGrid绑定时发生的事件处理

  一般用些事件来,做一些页面上的效果.如更改背景色,文本框大小等.
  OnItemDataBound="DataGrid1_ItemDataBound"
  ///<summary>
  ///响应DataGrid绑定事件
  ///</summary>
  ///<paramname="sender"></param>
  ///<paramname="e"></param>
  publicvoidDataGrid1_ItemDataBound(objectsender,System.Web.UI.WebControls.DataGridItemEventArgse)
  {
   if(e.Item.ItemType==ListItemType.Item)
   {
    e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#c8dafa’");
    e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’white’"); 
   }
   elseif(e.Item.ItemType==ListItemType.AlternatingItem)
   {
    e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#c8dafa’");
    e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’#f6f6f6’");
   }
  }
  
       10.为DataGrid控件添加接钮处理事件程序

  在DataGrid控件标签中加入如下代码
  OnItemCommand="ItemsGrid_Command"
  在后台中加入如下代码
  publicvoidItemsGrid_Command(Objectsender,DataGridCommandEventArgse)
  {
   switch(((LinkButton)e.CommandSource).CommandName)
   { 
    case"Delete":
     intclassID=Int32.Parse((e.Item.Cells[0].Text).ToString());
     ActorClass.DeleteActorClass(classID);
     if(Request.QueryString.Get("classID")!=null)
      Common.BindData(DataGrid1,Common.GetSource("select*fromActorClasswhereparentID="+Request.QueryString.Get("classID")+"orderbydepth,orderIDdesc"));
