3.删除表格选定记录 -rcEG!

★特别注意:【?id=】 处不能为 【?id =】 I;JV-jDM
6.表格超连接列传递参数 i;{lY1
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ $`GlXiV
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> *CXc{{

7.表格点击改变颜色 MkMDI)Y|

e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; (]cL5o9
this.style.color=’buttontext’;this.style.cursor=’default’;"); 5B)&;[
} 39O rY

写在DataGrid的_ItemDataBound里 I]d-WTd

{ 'MW%\W;
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; M *w{PjU

8.关于日期格式 |Io:D:
U)f('zD
日期格式设定 j"6|$Ze8
DataFormatString="{0:yyyy-MM-dd}" #b*4v&<
t<fah 3hl
我觉得应该在itembound事件中 [c=P)t7
V
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) :qxWANUa
s?;8h &]=
9.获取错误信息并到指定页面 5FJLDT2Lg
*7H
*epUa
不要使用Response.Redirect,而应该使用Server.Transfer roc DO8f
C~4SPCU
e.g rP]|`*B
// in global.asax _D}3``
protected void Application_Error(Object sender, EventArgs e) { 4o M~
if (Server.GetLastError() is HttpUnhandledException) Lqxhy s
Server.Transfer("MyErrorPage.aspx"); ^BLO}9A{P
1_S]t[?I/
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) xz0t8`NoN
} c=+%][21
;MNUT,U
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 c!
