1. 打开新的窗口并传送参数: gJ>?<F;
~_SV`io
传送参数: 3_IuK6K2
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") }@V(y9K
N`/6
By
接收参数: W:P4XwR{
string a = Request.QueryString("id"); Cl]E rg
string b = Request.QueryString("id1"); ~?dPF;.6_
im_W0tGvF
2.为按钮添加对话框 S >uzW #
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); EpeTfD
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") "j9,3yJT

3.删除表格选定记录 NrTQ}_3)
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; "7RQrz
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() '?_;s9)

4.删除表格记录警告 r9G<HKl

5.点击表格行链接另一页 xF5q=%n

//点击表格打开 DVRE ;+Jt

★特别注意:【?id=】 处不能为 【?id =】 v$w!hYsQ
6.表格超连接列传递参数
s<xD$K~rM
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ W j/.rG&tE
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> $k V^[
KDuM;
7.表格点击改变颜色 "N"9PTX

{ sE-E\+
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; [(5;jUmF@
this.style.color=’buttontext’;this.style.cursor=’default’;"); !t{3IE
} ]k_@F6 A
//\ORJd
写在DataGrid的_ItemDataBound里 (+38z)f
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) {$ HW_\w
{ &|IY=$-
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; ^{_`jE
this.style.color=’buttontext’;this.style.cursor=’default’;"); <jQ?l%\
e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’’;this.style.color=’’;"); 9@#Z6[=R,
} u} JL*}Q
^LE`Y>&m

8.关于日期格式 $OHY^IE(
#]oVVf_
日期格式设定 YL=?N k/
DataFormatString="{0:yyyy-MM-dd}" AM1 J ^Dp
"6lf~%R"
我觉得应该在itembound事件中 OA_:_%a(
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) LXG,IG
)$I;)`q
9.获取错误信息并到指定页面 /<9VKMR_k
:z56!qU
不要使用Response.Redirect,而应该使用Server.Transfer !%_Z>a
xXE/pIXw
e.g vX]\Jqy
// in global.asax SgHLs
protected void Application_Error(Object sender, EventArgs e) { k+{-iPm{
if (Server.GetLastError() is HttpUnhandledException) >o>r@;
Server.Transfer("MyErrorPage.aspx"); 4WG~7eIgy
s@E"EWp0
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) gXZ.je)NM
} d%\{,
0R>M_|
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 [iwn"e
