2.为按钮添加对话框 S $wx>715
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); N>,`l
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") l=(4o4um

3.删除表格选定记录 ~ Iin|
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; }e}J6[wP
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() H(qDQqJHYy

5.点击表格行链接另一页 $JKR,
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) .~#<>

//点击表格打开 <DG=qP6O

6.表格超连接列传递参数 Y8I*B=7

8.关于日期格式 s53Pw>f
%";bgU2Q
日期格式设定 >"qnuv G
DataFormatString="{0:yyyy-MM-dd}" R
+H0+omj
<uXZ*E
我觉得应该在itembound事件中 cPcp@Dp
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) _97A9wHj

9.获取错误信息并到指定页面 P qFK*^)s
Gni<@;}
不要使用Response.Redirect,而应该使用Server.Transfer #QdBI{2
@y,pfWh`
e.g d_CY=DHF%`
// in global.asax D+Osz
protected void Application_Error(Object sender, EventArgs e) { 7MXi_V;p<
if (Server.GetLastError() is HttpUnhandledException) eR,ePyA;
Server.Transfer("MyErrorPage.aspx"); 5[Sa7Mk
}?zy*yL
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) 0Da9,&D
} }^).Y7{g[
-LAYj:4
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 W0GDn
