1. 打开新的窗口并传送参数: x]gf3Tc58

传送参数: )PU?`yLTr
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") +([

wh\J)pA1
接收参数: os]P6TFFX?
string a = Request.QueryString("id"); luyU!
string b = Request.QueryString("id1"); B!=JRfT

2.为按钮添加对话框 eJB !|

button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") HY,+;tf2r

3.删除表格选定记录 /=zzym~<>
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; Khbkv
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() =U6%Wdth

4.删除表格记录警告 p=Nord

5.点击表格行链接另一页 /YbyMj*

{ 4~Ptn / g
//点击表格打开 a1;P2ikuK
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) B5>1T[T'-

6.表格超连接列传递参数 oVPtA@
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ 2Y~6~*8*~
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> >#}MDwKZD

7.表格点击改变颜色 %vjLw`
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) zGrUl|j
{ !r:X`~\a
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; h+e Oe}

8.关于日期格式 RZm}%6##ZC
}mRus<Ax
日期格式设定 z;:c_y!f
DataFormatString="{0:yyyy-MM-dd}" (are2!Oq
8d9&LPv
我觉得应该在itembound事件中 zk8 o[4
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) M17oAVN7D

9.获取错误信息并到指定页面 ahi lp$v
'P{0K?{H-4
不要使用Response.Redirect,而应该使用Server.Transfer Fy|tKMhnc
ta]B9&c
e.g E"l&<U
// in global.asax uGm~ Oo
protected void Application_Error(Object sender, EventArgs e) { %4#,y(dO
if (Server.GetLastError() is HttpUnhandledException) 5urM,1SQ@
Server.Transfer("MyErrorPage.aspx"); :fI|>I
~
" , c1z\
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) DA)+)PhY7K
} UW7*,B q
1PWs">*(
Redirect会导致post-back的产生从而丢失了错误信息,所以页面导向应该直接在服务器端执行,这样就可以在错误处理页面得到出错信息并进行相应的处理 %M{qr!?uj
