3.删除表格选定记录 /ESmQc:DWB
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; (A.%q1h
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() <"|BuK

6.表格超连接列传递参数 sMh3IL9(*
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ v@bs4E46e
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> Ql-RbM

7.表格点击改变颜色 "T4Z#t
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) S5R Q
{ 3| 5Af
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; ?YR/'Vq97
this.style.color=’buttontext’;this.style.cursor=’default’;"); Bor _Kib

写在DataGrid的_ItemDataBound里 SJhcmx+

e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; #&vP(4p

8.关于日期格式 jdxwS
OZdiM&Zss
日期格式设定 gf6<`+/
DataFormatString="{0:yyyy-MM-dd}" @;m7u
/YYI

我觉得应该在itembound事件中 x6A*vP0nm)
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) SEm3T4dfzf

9.获取错误信息并到指定页面 WTi8
OF^v;4u
不要使用Response.Redirect,而应该使用Server.Transfer F$Q(2:w
F)4Y;;#
e.g (xffU%C^
// in global.asax _uL{@(
protected void Application_Error(Object sender, EventArgs e) { 9W$FX
if (Server.GetLastError() is HttpUnhandledException) \`?l6'!
Server.Transfer("MyErrorPage.aspx"); =\7o@ 38
-~Kw~RX<(
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) X-Y:)UT
} 0sW=;R2
OgjSyzc
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 H3T4v1o6

10.清空Cookie L{xCsJ3d
Cookie.Expires=[DateTime]; }9[E+8L1
Response.Cookies("UserName").Expires = 0 @K`2y'#b
