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

3.删除表格选定记录 c:.5@eq^
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; "kFH*I+v
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() r1-MO`6

//点击表格打开 "i#g [x
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) 4y3c=L

6.表格超连接列传递参数 6~0kb_td
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ cKkH*0B5
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> ~L<"]V+B

7.表格点击改变颜色 QObVJg,GD
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) 02[m{a-
{ Q?1.GuF
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; a_}C*+D
this.style.color=’buttontext’;this.style.cursor=’default’;"); \K\eq>@6
} R7(XDX=[s
&PV%=/-J
写在DataGrid的_ItemDataBound里 "$(D7yFO
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) tL;.vRx
{ ;yNY/
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; |%5Aku0`s

e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’’;this.style.color=’’;"); \jk*Nm8;
} l2n`fZL

8.关于日期格式 FNraof @Oy
kBA.N l7
日期格式设定 bi}aVtG~z
DataFormatString="{0:yyyy-MM-dd}" dF51_Kk
~;$QSO\2h
我觉得应该在itembound事件中 L3oL>r'|
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) LqD7SJ}/f
?Ybq]J\q
9.获取错误信息并到指定页面 RYvcuA)
"ADI.
不要使用Response.Redirect,而应该使用Server.Transfer
YC6guy>
T;B FO5G@
e.g L bJf5xdi
// in global.asax 2Cy,#X%j>
protected void Application_Error(Object sender, EventArgs e) { z@e(y@
if (Server.GetLastError() is HttpUnhandledException) +$L}B-F
Server.Transfer("MyErrorPage.aspx"); $t& o(]m
]'%
iR
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) ;Ngk"5
} OHAU@*[lM
}X8P5c!\
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 #J/RI[a
