1. 打开新的窗口并传送参数: -tZb\4kh
<h[^&CY{
传送参数: C%"@|01cO
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") ,3u19>2
nr;/:[F
接收参数: me" <+6
string a = Request.QueryString("id"); {S!~pn&^Y
string b = Request.QueryString("id1"); }e)ltp|
q 9^r2OO
2.为按钮添加对话框 \W!<xE
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); 5T`39[Fya
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") 9'M({/7y

3.删除表格选定记录 b-XBs7OAx
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; FliN@RNo
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() "`zw(
9UX-)!
4.删除表格记录警告 j^M@0o

5.点击表格行链接另一页 _G42|lA$/

6.表格超连接列传递参数 /lUb9&yV
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ w% M0Mu
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> DF#Ob( 1

7.表格点击改变颜色 ) ":~`Z*@

e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’’;this.style.color=’’;"); mu*wX'.'

8.关于日期格式 TJCoID7a8
-7lJ
日期格式设定 UrgvG, Lt
DataFormatString="{0:yyyy-MM-dd}" +Q{jV^IT9
]wP)!UZ
我觉得应该在itembound事件中 7eY*Y"GX
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) U*zjEY:A
(FBKP#x)^
9.获取错误信息并到指定页面 7Y_S%B:F
]+oPwp;il
不要使用Response.Redirect,而应该使用Server.Transfer p%n}a%%I
YoXXelO&
e.g 0 {w?u %'
// in global.asax B}:[~R'
protected void Application_Error(Object sender, EventArgs e) { \!-X&ws
if (Server.GetLastError() is HttpUnhandledException) k38Ds_sW6d
Server.Transfer("MyErrorPage.aspx"); mI l_
[
yfq"atj
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) =oSv=xY
} %lvSO/F+
[
%r :V"
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 b-wFnMXk+
