1. 打开新的窗口并传送参数: >|uZIcs 6

传送参数: Y/)>\
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") MP0gLi

接收参数: NqlG= pu
string a = Request.QueryString("id"); cKF 8(
string b = Request.QueryString("id1"); tb{l(up/a

2.为按钮添加对话框 lE$X9yIt
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); Dgp"RUP
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") 0alm/or

3.删除表格选定记录 #RZW)Br
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex];
z.P)
:Er
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() o;_v'

4.删除表格记录警告 3%!d&j>v

5.点击表格行链接另一页 ~4`LOROC
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) 7%V2
{ -|"mB"Dc
//点击表格打开 1|q$Wn:*
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) NoV)}fX$X8
e.Item.Attributes.Add("onclick","window.open(’Default.aspx?id=" + e.Item.Cells[0].Text + "’);"); R'u M7,7
} [wj&.I{^s
{%)bxk6
双击表格连接到另一页 &C`t(e
)F8G q,
在itemDataBind事件中 `h+ sSIko
if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) &S>m+m'

string OrderItemID =e.item.cells[1].Text; V{HP8f91

} :aS8%m
O(2)A>}
★特别注意:【?id=】 处不能为 【?id =】 'vq-~y5^#
6.表格超连接列传递参数 (j@3=-%6 G
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ U p=J&^.
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> ae`*0wbv

7.表格点击改变颜色 V^Z"FwWk
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) .bE+dA6:v
{ )kfj+/
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; !B5 }`*1D
this.style.color=’buttontext’;this.style.cursor=’default’;"); &ejJf{id
} Q(=} PF
%C^U?m`
写在DataGrid的_ItemDataBound里 KAVe~j"
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) r%\(5H f
{ -'ePx f
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; 6c>cq\~E

e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’’;this.style.color=’’;"); CT(VV6I\

8.关于日期格式 pxy=edd
d~n|F|`:
日期格式设定 ++=t|ZS
U
DataFormatString="{0:yyyy-MM-dd}" }QrBN:a$(
mux_S2x9m\
我觉得应该在itembound事件中 Qa-]IKOs
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) k@vN_Un
<\40?*2
9.获取错误信息并到指定页面 [\+"<;m$
G>"=Af(t?Y
不要使用Response.Redirect,而应该使用Server.Transfer eFJ .)Z
@)n xX))a
e.g a
k&G=a6^
// in global.asax H5wzzSV!:B
protected void Application_Error(Object sender, EventArgs e) { 2UqLV^ZY
if (Server.GetLastError() is HttpUnhandledException) g+'=#NS}
Server.Transfer("MyErrorPage.aspx"); 3jH-!M5
j8gw]V/B:
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) Y.FqWJP=p
} )> >Tj7
BCUn[4Gp
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 }_,1i3Rip

10.清空Cookie :g@H=W
Cookie.Expires=[DateTime]; Y'n+,g
Response.Cookies("UserName").Expires = 0 9*`(*>S
