1. 打开新的窗口并传送参数: FJ*i\Q/D

传送参数: <R%;~) {
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") 2 oa#0`{

接收参数: ZT02"3F
string a = Request.QueryString("id"); 1:NrP'W^
string b = Request.QueryString("id1"); "G-1>:

2.为按钮添加对话框 gH2,\z`[4
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); B63pgPX
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") YY?a>j."a

3.删除表格选定记录 N=:5eAza
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; 0JgL2ayIVI
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() ^mAYBOE

5.点击表格行链接另一页 v+jsC`m
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) KXV[OF&J
{ AtR?J"3E
//点击表格打开 <I}2k
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) t}v2$<!I

双击表格连接到另一页 g}p;\o

在itemDataBind事件中 iK?b~Q

★特别注意:【?id=】 处不能为 【?id =】 pZ#ap<|>I
6.表格超连接列传递参数 v/ *Y#(X
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ 2<mW\$
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> sH[

7.表格点击改变颜色 K[chjp!$l
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) pT?Q#,fh
{ 0A{/B/r
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; *m%]zj0bo
this.style.color=’buttontext’;this.style.cursor=’default’;"); $+}+zZX5
} FgL,k
+n}$pM|NKU
写在DataGrid的_ItemDataBound里 PSawMPw
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) tNVV)C
{ %gnM(pxl
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; gX{loG
this.style.color=’buttontext’;this.style.cursor=’default’;"); TpA\9N#$
e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’’;this.style.color=’’;"); fQLt=Lrp
} ,@m@S^

8.关于日期格式 kY]W
Qu
PpLU
日期格式设定 [sW.CK=3
DataFormatString="{0:yyyy-MM-dd}" +i\&6HGK;-
Sx
我觉得应该在itembound事件中 #d{=\$=
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) G8W#<1LE
RtG}h[k/X
9.获取错误信息并到指定页面 ^IKO2Ft
`IYuz:
不要使用Response.Redirect,而应该使用Server.Transfer p0.|<
KYJjwXT28W
e.g ~)?
// in global.asax fjnT e
protected void Application_Error(Object sender, EventArgs e) { `[zQf
if (Server.GetLastError() is HttpUnhandledException) GRy-+#,b"
Server.Transfer("MyErrorPage.aspx"); =66Nw(E.
E&Qi@Ty
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) pj?XLiM54%
} 0?WcoPU
bslrqUk_`=
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 Y2o6kS{x

10.清空Cookie "uLjIIl
Cookie.Expires=[DateTime]; +!f=jg06
Response.Cookies("UserName").Expires = 0 ( 6(x'ByT

11.自定义异常处理 %LXM+<N8
