Asp.net web form url route usage summary, asp. netroute

Use URL routing in asp.net web form.

I. Foreground controls use RoutingGenerate a url address using an expression. Note that the route parameter is assigned a value to prevent other route expression values from being used.
Method 1:
<Asp: HyperLink ID = "hlSupply" NavigateUrl = '<% $ RouteUrl: routename = TechSupplySearch, areacode =, techfield = %>'
Runat = "server"> technology supply </asp: HyperLink>
Method 2:
<A href = "<% = GetRouteUrl (" MemberSearch ", new {membertype =" commp any ", areacode =" ", industrycode =" ", pageindex = ""}) %> "> Technology Enterprises </a>

Used in data binding on the control interface
<Asp: Repeater ID = "myGrid" ViewStateMode = "Disabled" runat = "server">
<ItemTemplate>
<Li> <a target = "_ blank" href = '<% # this. getRouteUrl ("TechSupplyView", new {id = Eval ("SupplyId")}) %> '> <% # Eval ("SupplyName ") %> </a> <span> <% # string. isNullOrEmpty (Eval ("cityname "). toString ())? "& Nbsp": Eval ("cityname") %> </span> <% # Eval ("hightech") %> </span> </li>
</ItemTemplate>
</Asp: Repeater>

Url routing pagination control: urlpager

Ii. Use routing in the server background code

1. Global. asax file:
Void Application_Start (object sender, EventArgs e)
{
// Code that runs when the application starts
RegisterRoutes (RouteTable. Routes );
}
// Register url Routing
Void RegisterRoutes (RouteCollection routes)
{
Routes. routeExistingFiles = false; // by default, URLs that are not routed to the same physical path, such as http: // localhost/MyFolder/MyPage. the advantage of aspx is that static resource files are not routed. Otherwise, static files such as js and css may trigger Page_Load events multiple times.

// Routes. Ignore ("{resource}. axd/{* pathinfo}"); // the routing of static resource files is not valid in this way.
// Routes. Ignore ("{path}/{name).jpg"); // the routing of static resource files is not valid in this way.


// Register a route
Routes. MapPageRoute ("TechNewsSearch", "TechNews/{pageindex }","~ /NewsInfo/TechNewsSearch. aspx ", true, new RouteValueDictionary {" pageindex "," 1 "}}, new RouteValueDictionary {" pageindex ", @" \ d {1 ,}"}});

Routes. MapPageRoute ("TechSupplySearch", "Supply/{areacode}/{techfield}/{pageindex }","~ /TechSupply/TechSupplySearch. aspx ", true, new RouteValueDictionary {" areacode "," 0 "},{" techfield "," 0 "},{" pageindex "," 1 "}}, new RouteValueDictionary {"pageindex", @ "\ d {1 ,}"}});

Routes. MapPageRoute ("MemberSearch", "Members/{membertype}/{areacode}/{industrycode}/{pageindex }","~ /Member/MemberSearch. aspx ", true, new RouteValueDictionary {" membertype "," 0 "},{" areacode "," 0 "},{" industrycode "," 0 "}, {"pageindex", "1" }}, new RouteValueDictionary {"pageindex", @ "\ d {1 ,}"}});
}

2. Use WebForm in background code

Obtain and change route parameter values
RouteValue = Page. RouteData. Values ["techfield"] = null? String. Empty: Page. RouteData. Values ["techfield"]. ToString (); // obtain route Parameters

Page. RouteData. Values ["areacode"] = selOrgan. SelectedValue; // modify route Parameters

Page. RouteData. Values. Remove ("Over"); // Remove route Parameters

Generate a route address in the background code
NewUrl = this. GetRouteUrl ("MemberSearch", Page. RouteData. Values );

Implementation of webpage client jump Routing
Response. RedirectToRoute ("TechSupplySearch", Page. RouteData. Values );
Response. RedirectToRoutePermanent ("TechSupplySearch", Page. RouteData. Values );
