2.为按钮添加对话框 _j}jh[M
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); X@H/"B%u2
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") JbXd9AMh2

3.删除表格选定记录 (u-eL#@
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; v&8s>~i`K
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() =a!_H=+4

4.删除表格记录警告 /SD(g@G,

e.Item.Attributes.Add("onclick","window.open(’Default.aspx?id=" + e.Item.Cells[0].Text + "’);"); D-LQQ{!D5

6.表格超连接列传递参数 $B`ETI9g-N
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ mYbu1542'n
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> e!vWGnY

7.表格点击改变颜色 JA% y{Wb
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) Vi#[kn'
{ =^z*p9ZB
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; +mN8uU~(kx
this.style.color=’buttontext’;this.style.cursor=’default’;"); 5w5"rcV
} `aSbGMz
`>=@Kc
写在DataGrid的_ItemDataBound里 8S5Q{[ !
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) {4*5Z[
{ ~5>TMIDiuR
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; ?

8.关于日期格式 rNICK2Ah
Gn4XVzB`O
日期格式设定 bI8')a
DataFormatString="{0:yyyy-MM-dd}" (a"/cH
7Kpv fyL{
我觉得应该在itembound事件中 %S^:5#9
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) ,+X:#$
h@J3+u<
9.获取错误信息并到指定页面 ?v`24p3PC
ilZQ/hOBH
不要使用Response.Redirect,而应该使用Server.Transfer 9A87vs4[
2b Fr8FUt-
e.g x4,[5N"}YK
// in global.asax OTNI@jQ)
protected void Application_Error(Object sender, EventArgs e) { 'j!n
if (Server.GetLastError() is HttpUnhandledException) ) )t]5Ys%;
Server.Transfer("MyErrorPage.aspx"); ]YOWCFAQot
TaF;PGjVw
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) uMRzUK`QK
} E33WT{H&_'
<9c{Kt.5(
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 jvpv1>KYV
