1. 打开新的窗口并传送参数: //传送参数:
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="++"’)</script>")
  //接收参数:
string a = Request.QueryString("id");
string b = Request.QueryString("id1");2.为按钮添加对话框
Button1.Attributes.Add("onclick","return confirm(’确认?’)");
button.attributes.add("onclick","if(confirm(’are you sure?’)){return true;}else{return false;}")3.删除表格选定记录
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex];
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString()4.删除表格记录警告
private void DataGrid_ItemCreated(Object sender,DataGridItemEventArgs e)
{
 switch(e.Item.ItemType)
 {
  case ListItemType.Item :
  case ListItemType.AlternatingItem :
  case ListItemType.EditItem:
   TableCell myTableCell;
   myTableCell = e.Item.Cells[14];
   LinkButton myDeleteButton ;
   myDeleteButton = (LinkButton)myTableCell.Controls[0];
   myDeleteButton.Attributes.Add("onclick","return confirm(’您是否确定要删除这条信息’);");
   break;
  default:
   break;
 }
}
5.点击表格行链接另一页
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
 //点击表格打开
 if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
  e.Item.Attributes.Add("onclick","window.open(’Default.aspx?id=" + e.Item.Cells[0].Text + "’);");
}
  //双击表格连接到另一页
  //在itemDataBind事件中
if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
 string OrderItemID =e.item.cells[1].Text;
 
 e.item.Attributes.Add("ondblclick", "location.href=’../ShippedGrid.aspx?id=" + OrderItemID + "’");
}
   //双击表格打开新一页
if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
 string OrderItemID =e.item.cells[1].Text;
 
 e.item.Attributes.Add("ondblclick", "open(’../ShippedGrid.aspx?id=" + OrderItemID + "’)");
}
  ★特别注意:【?id=】 处不能为 【?id =】6.表格超连接列传递参数
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’
 <%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ />7.表格点击改变颜色
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem)
{
 e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’;
    this.style.color=’buttontext’;this.style.cursor=’default’;");
}
  写在DataGrid的_ItemDataBound里
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem)
{
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’;
   this.style.color=’buttontext’;this.style.cursor=’default’;");
e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’’;this.style.color=’’;");
}

8.关于日期格式

日期格式设定
DataFormatString="{0:yyyy-MM-dd}"
  //我觉得应该在itembound事件中
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd"))9.获取错误信息并到指定页面
//不要使用Response.Redirect,而应该使用Server.Transfer
  e.g
// in global.asax
protected void Application_Error(Object sender, EventArgs e) {
if (Server.GetLastError() is HttpUnhandledException)
Server.Transfer("MyErrorPage.aspx");

//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :)
}
  //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 10.清空Cookie Cookie.Expires=[DateTime];
Response.Cookies("UserName").Expires = 0
web窗体状态栏内类似跑马等效果的实现
第一步:定义一个javascript代码段

<script language="javascript">
var strMsg = "          欢迎光临本站点by loveFXN    &n
