我常用的《ASP.NET语句》
1.//弹出对话框.点击转向指定页面Response.Write(" <script>window.alert(’该会员没有提交申请,请重新提交！’)
</script>");
Response.Write(" <script>window.location
=’http://www.51aspx.com/bizpulic/upmeb.aspx’ </script>");
2.//弹出对话框
Response.Write(" <script language=’javascript’>alert(’产品添加成功！’)
</script >");
3.//删除文件
string filename ="20059595157517.jpg";
pub.util.DeleteFile(HttpContext.Current.Server.MapPath("../file/")
+filename);
4.//绑定下拉列表框datalist
System.Data.DataView dv=conn.Exec_ex("select -1 as code,’请选择经营模式’
as content from dealin union select code,content from dealin");
this.dealincode.DataSource=dv;
this.dealincode.DataTextField="content";
this.dealincode.DataValueField="code";
this.dealincode.DataBind();
this.dealincode.Items.FindByValue(dv[0]["dealincode"].ToString
()).Selected=true;
5.//时间去秒显示
<%# System.DateTime.Parse(DataBinder.Eval
(Container.DataItem,"begtime").ToString()).ToShortDateString()%>
6.//标题带链接
<%# " <a class=\"12c\" target=\"_blank\"
href=\"http://www.51aspx/CV/_"+DataBinder.Eval
(Container.DataItem,"procode")+".html\">"+
DataBinder.Eval(Container.DataItem,"proname")+" </a>"%>
7.//修改转向
<%# " <A href=\"editpushpro.aspx?id="+DataBinder.Eval
(Container.DataItem,"code")+"\">"+"修改
"+" </A>"%>
8.//弹出确定按钮
<%# " <A id=\"btnDelete\" onclick=\"return confirm(’你是否
确定删除这条记录吗?’);\" href=\"pushproduct.aspx?
dl="+DataBinder.Eval(Container.DataItem,"code")
+"\">"+"删除"+" </A>"%>
9.//输出数据格式化 "{0:F2}" 是格式 F2表示小数点后剩两位
<%# DataBinder.Eval(Container, "DataItem.PriceMoney","{0:F2}
") %>
10.//提取动态网页内容
Uri uri = new Uri("http://www.51aspx.com/");
WebRequest req = WebRequest.Create(uri);
WebResponse resp = req.GetResponse();
Stream str = resp.GetResponseStream();
StreamReader sr = new StreamReader(str,System.Text.Encoding.Default);
string t = sr.ReadToEnd();
this.Response.Write(t.ToString());
11.//获取" . "后面的字符
i.ToString().Trim().Substring(i.ToString().Trim().LastIndexOf(".")
+1).ToLower().Trim()
12. 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");
12.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;}")

13.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()
14.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;
}
}
15.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)
{

e.item.Attributes.Add("ondblclick", "open
(’../ShippedGrid.aspx?id=" + orderItemID + "’)");
}
