1.弹出对话框.点击转向指定页面
Code:
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 ='https://www.itmop.com/'</script>");
2.弹出对话框
Code:
Response.Write("<script language='javascript'>alert('产品添加成功!')</script >");
3.删除文件
Code:
string filename ="20059595157517.jpg";
pub.util.DeleteFile(HttpContext.Current.Server.MapPath("../file/")+filename);
4.绑定下拉列表框datalist
Code:
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
Code:
<%# System.DateTime.Parse(DataBinder.Eval(Container.DataItem,"begtime").ToString()).ToShortDateString()%>
6.标题带链接
Code:
<%# "<a class=\"12c\" target=\"_blank\" href=\"https://www.51aspx/CV/_"+DataBinder.Eval(Container.DataItem,"procode")+".html\">"+ DataBinder.Eval(Container.DataItem,"proname")+"</a>"%>
7.修改转向
Code:
<%# "<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
Code:
<%# DataBinder.Eval(Container, "DataItem.PriceMoney","{0:F2}") %>
10.提取动态网页内容
Code:
Uri uri = new Uri("https://www.itmop.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
Code:
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:
Code:
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>")
接收参数:
Code:
string a = Request.QueryString("id");
string b = Request.QueryString("id1");
12.为按钮添加对话框
Code:
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
Code:
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
Code:
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
Code:
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
Code:
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
Code:
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
Code:
<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
Code:
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
Code:
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=’’;");
}
18.关于日期格式
日期格式设定
Code:
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"))
Code:
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
Code:
// in global.asax
protected void Application_Error(Object sender, EventArgs e) {
if (Server.GetLastError() is HttpUnhandledException)
Server.Tra
