传送参数: eHfG;NsV/
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") *RUd!]bh
HXlr
接收参数: ;@h'Mb
string a = Request.QueryString("id"); sYW1T @
string b = Request.QueryString("id1"); 4okHAv8;

2.为按钮添加对话框 fS8XuT
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); _ d(Ks9
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") v ](G?L9b

3.删除表格选定记录 `"^@[1
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; =PeW$q+
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() N7Z(lI|a;

4.删除表格记录警告 Huug_E+

5.点击表格行链接另一页 p0:&7,+a,
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) 4u{E D(
{ Cx1Sh#9
//点击表格打开 z!t3xFN&/
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) Xoa<r9
e.Item.Attributes.Add("onclick","window.open(’Default.aspx?id=" + e.Item.Cells[0].Text + "’);"); $O8EiC!f6

} OB? 79l

★特别注意:【?id=】 处不能为 【?id =】 )uv$tnP*
6.表格超连接列传递参数 (w7cdqe
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ '=G<)z@k
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> ~)\1g0
-fZShOBY`
7.表格点击改变颜色 OHa{!SaL
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) kosJ]q'U
{ Q/9vDv
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; IB]VPj5
this.style.color=’buttontext’;this.style.cursor=’default’;"); &V,-W0T_
} AQBx
k[
`X]2iz
写在DataGrid的_ItemDataBound里 /\Y%DpG$
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) ~ @"Qm;}
"
{ gCBZA;/
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; Uc%`? +Q
this.style.color=’buttontext’;this.style.cursor=’default’;"); }?ac<> u&
e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’’;this.style.color=’’;"); M6 >\R$
} /-<m(72wF
gQzJ2LU(
0_xcrM
8.关于日期格式 bU +eJU_%
J;]@?(
日期格式设定 NB6h/0*v
DataFormatString="{0:yyyy-MM-dd}" #L*@~M^]
%cjGeS6}
我觉得应该在itembound事件中 KL_}:O68
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) /n 3&e
0o'ML""j
9.获取错误信息并到指定页面 y7L4jO9h
p-03V"^&
不要使用Response.Redirect,而应该使用Server.Transfer bJMcI8`
+H^V},dBp!
e.g qFsg&<
// in global.asax o4
OEA)k)=
protected void Application_Error(Object sender, EventArgs e) { kviSQM2
if (Server.GetLastError() is HttpUnhandledException) x[uXD
Server.Transfer("MyErrorPage.aspx"); kk7:A0._
~X(xa
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) w!9W Cl]9M
} k^%ec3l
,8 NEnB
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 l$~bkVNL

10.清空Cookie OU3+SYM
