2.为按钮添加对话框 CxwZ$0
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); +e4o~p
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") S^~GI$

3.删除表格选定记录 +]Ydf^rF
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; NbfV6$jo
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() H{9di\xnEm

4.删除表格记录警告 p"Fj6T2

5.点击表格行链接另一页 0I& !a$:
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) {_l@ws
{ Bo_Ivhe[m
//点击表格打开 9>\s81^
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) b=`h""u
e.Item.Attributes.Add("onclick","window.open(’Default.aspx?id=" + e.Item.Cells[0].Text + "’);"); xR\$2(
} 27G6C`}

双击表格连接到另一页 t%V!SvT8+

在itemDataBind事件中 K`768%q

★特别注意:【?id=】 处不能为 【?id =】 yk,o*g
6.表格超连接列传递参数 g%Sl+gWdJ
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ V*2uW2\}
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> D:/^TEib

7.表格点击改变颜色 aI{Ehbf=
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) oM M`7wJw
{ HSE9-c=
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; g
VplBF7{
this.style.color=’buttontext’;this.style.cursor=’default’;"); m?V4r#t
}

写在DataGrid的_ItemDataBound里 #ih(I7prH
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) T'"aStt6
{ Np$pz
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; odD^xg"L

e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’’;this.style.color=’’;"); /Q8E12

8.关于日期格式 ba^B$$?B o
yIC8Rl
日期格式设定 @7e h/|Y,
DataFormatString="{0:yyyy-MM-dd}" ?suNA
g[!t@K
我觉得应该在itembound事件中 w$MFCJ:p&
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) NTkGLD1e.
4p\<b8(9>
9.获取错误信息并到指定页面 *Fi`o_d9[`
J=JYf_=4bc
不要使用Response.Redirect,而应该使用Server.Transfer 7Ps I'1v
4Z12Z@ A#7
e.g M_<O'Ii3
// in global.asax meA=lg?
protected void Application_Error(Object sender, EventArgs e) { ,]+P#eXgE
if (Server.GetLastError() is HttpUnhandledException) L}T:Y).
Server.Transfer("MyErrorPage.aspx"); f 0A0uU8y
mEyJ
o|
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) ]3uErnI
} c=p`5sN)
a;WRTV
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 $1y8gm

Response.Cookies("UserName").Expires = 0 =ZR9zL=h
