2.为按钮添加对话框 :JSOj@s
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); <!&&Qd-d6H
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") #zXkg[J6d

3.删除表格选定记录 :?{ **&=
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; `ejE)VL=8h
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() r9G<HKl

4.删除表格记录警告 v\t$. _at

5.点击表格行链接另一页 JMpjiB,A}
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) h{yqNl
{ d> `9!)
//点击表格打开 3*3WO,9
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) ~DVAk|fc
e.Item.Attributes.Add("onclick","window.open(’Default.aspx?id=" + e.Item.Cells[0].Text + "’);"); oKiBnj5J

双击表格连接到另一页 |SZRO,7x

e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; K~5QL/=1

8.关于日期格式 iv2did4
wbshKkUh_*
日期格式设定 SEq_37
DataFormatString="{0:yyyy-MM-dd}" ZMy0iQ@
bX:Y5o49
我觉得应该在itembound事件中 ^]3Y11sI
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) o"->RC
r`pg`ChHv
9.获取错误信息并到指定页面 Zj99]4?9
2--"@@
不要使用Response.Redirect,而应该使用Server.Transfer X(U
CN0#
o;.PZi2k
e.g ~Jrtm7
// in global.asax NOLw119K
protected void Application_Error(Object sender, EventArgs e) { +VkhM;'"C
if (Server.GetLastError() is HttpUnhandledException) "G-}
wt+P
Server.Transfer("MyErrorPage.aspx"); iUJqAi1o
@cA`del
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) $73 7oV<
} BoE;,s>]NW
v*SSc5gFG
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 wN\%b}pp
