1. Firefox Google is centered
1、要有document的标题
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd" >
<html xmlns="http://www.w3.org/1999/xhtml" >
2、父级容器要定宽度、text-aling、 margin 0 auto
.newsletter_column1{ width:166px; min-height:150px; float:left; margin-right:40px; margin-bottom:20px;text-align:center;}
.newsletter_column1 span {text-align:center;margin:5px auto; font-weight:bold;}
二、Sys.WebForms.PageRequestManagerServerErrorException An unknown error occurred while processing the request on the server. The status code returned from the server was 500
<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="false"/>
在配置文件<system.web>下面添加
<httpRuntime requestValidationMode="2.0" maxRequestLength="8192" />
Three, view the Sql generated by EF
using(var ctx = new TestDBEntities)
{
var query = ctx.Clients.Where(c => c.Status == 1)
.OrderBy(c => c.ComputerName);
//Debug output SQL, note that query cannot be ToList( ), otherwise it is not IQueryable.
Debug.WriteLine((query as ObjectQuery). ToTraceString() );
//Follow-up business logic processing data
foreach(var client in query)
{
//...
}
}
Fourth, HyperLinkField Multi-parameter
<asp:HyperLinkField Text="查看" DataNavigateUrlFormatString="AuditQuestion_Edit.aspx?sid={0}&;staskid={1}&cmd=Look" DataNavigateUrlFields="sid,staskid"></asp:HyperLinkField>
Five, add specific routing rules to an Action
context.MapRoute(
"test", // Route name
"Wap/{controller}/{action}/{uID}/{BarCode}/{id}", // URL with parameters
new {controller = "Home1" , action = "ScanResult"} // parameter default value
);
public ActionResult ScanResult(int uID, string BarCode,int id=22)
6. The GridView data source does not have any attributes or characteristics that can be used to generate columns
The data source bound to the GridView is List<T>
. This error will be reported when the property in T does not have a get set.
Just add get set.
Seven, iis7 httplocalhostiisstart.htm or http127.0.0.1iisstart.htm open is a blank page
Control Panel-Programs and Features-Turn Windows features on or off-Internet Information Services -> World Wide Web Services -> Common HTTP functions. HTTP errors and redirection are less selected.
