//点击表格打开 FV>xAU$

★特别注意:【?id=】 处不能为 【?id =】 2apQ4)6#[H
6.表格超连接列传递参数 <#5`%sa '
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ *N?y <U
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> '<KzWxuC

7.表格点击改变颜色 Q=cbHDB
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) a FrVP
{ !Knv/:+
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; n:5*Tg9
this.style.color=’buttontext’;this.style.cursor=’default’;"); hR3Pa'/i
} ?.&?4*u
^_^rI+cTX1
写在DataGrid的_ItemDataBound里 #$(wfb9
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) /DQcM.3
{ vy+9Q5@W
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; )#n>))
this.style.color=’buttontext’;this.style.cursor=’default’;"); dwt<s[k
e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’’;this.style.color=’’;"); u:7=Yy

8.关于日期格式 JI}p{yI
`[J(au$z
日期格式设定 K\GIh8L
DataFormatString="{0:yyyy-MM-dd}" lt&30nf=
hrr ;=q$
我觉得应该在itembound事件中 dLek4q
`l
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd"))

9.获取错误信息并到指定页面 y|+ltA K
AH(O"v`
不要使用Response.Redirect,而应该使用Server.Transfer Eh)VU_D
SEXLi8;/
e.g 7#R&
OQ
// in global.asax {l7@<xZ??M
protected void Application_Error(Object sender, EventArgs e) { (d C<N3
if (Server.GetLastError() is HttpUnhandledException) s=nE'/q1|
Server.Transfer("MyErrorPage.aspx"); db!2nImNu\
u?f3&pA
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) _u :4y4}
} ~;;_POm
:6z0Ep"
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~Dq0 T
