1.//弹出对话框.点击转向指定页面
Response.Write(" <script>window.alrt('该会员没有提交申请,请重新提交!') </script>");
Response.Write(" <script>window.loation='http://www.cnblogs.com/kevin1031" target="_blank">http://www.cnblogs.com/' </script>");
2.//弹出对话框
Response.Write("<script language="javascript">alrt('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
datalistSystem.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
Code<%#"<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.cnblogs.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></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
Codeint 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",";"); }
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 + "’)");
}
16.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")%>’ / >
17.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’;"); }
18.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"))
19.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
20.清空Cookie
Cookie.Expires=[DateTime]; Response.Cookies("UserName").Expires = 0
