2.为按钮添加对话框 fgYdKv8
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); '}4LHB;:
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") @V:4tG.<sw

3.删除表格选定记录 c*$&MCh
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex];
bz'V50
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() jdiFb~5R

5.点击表格行链接另一页 S@;>lw,s!
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) #aUe7~
{ 6[>UF!.=
//点击表格打开 zk= 3L} C
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) T<kyxbjR
e.Item.Attributes.Add("onclick","window.open(’Default.aspx?id=" + e.Item.Cells[0].Text + "’);"); JTB_-J-TU

★特别注意:【?id=】 处不能为 【?id =】 Qa~dd{?
6.表格超连接列传递参数 3lYM(DT
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ N}Ozm6Mc
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> NY(c4fzl

7.表格点击改变颜色 e{@TR x
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) H~x,\|l#
{ qYZ\<h^
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; j;@7V4'
this.style.color=’buttontext’;this.style.cursor=’default’;"); l<0BMw S8

e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; (:W=8G,p

8.关于日期格式 :{<( )gfk
W_(
日期格式设定 OLpE0gZ.|`
DataFormatString="{0:yyyy-MM-dd}" v`8dRVN

我觉得应该在itembound事件中 Pda(O;aNU
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) J@'}lG

9.获取错误信息并到指定页面 UV8,SSDTV

RjxO.~U
不要使用Response.Redirect,而应该使用Server.Transfer Z=`\U?,
}wzU<(Rx
e.g Z{nJ\`
// in global.asax ~L
j[xP
protected void Application_Error(Object sender, EventArgs e) { A7@5lHMF
if (Server.GetLastError() is HttpUnhandledException) c`I`@Bed
Server.Transfer("MyErrorPage.aspx"); <EKDP>,~
>!:uVS
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) .hW_P62\#
} /N(L52mz
diN5*CF'~
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 _

Cookie.Expires=[DateTime]; {'P7D4w
Response.Cookies("UserName").Expires = 0 H: q(T
