I recently encountered many unsolved problems in the RIA + siverlight project. It's really a headache. I have to think about it over and over again, and I'll write an article to record it. If anyone from other countries can pass this place, I would be more grateful if I could give some advice .. Let's talk less about the problem .. Problem description: the server customizes an entity class that is not associated with the data and returns the object c

1. Add business logic to intermediate code In the RIA service, some business logic usually involves no client calls, but the middle layer is indispensable, that is, only access in the middle layer, the client does not need to access, you do not need to expose this method as a service and use the IgnoreAttribute feature to mark this method. This method is invisible on the client. The following example adds a new application (if the application name is

First, introduce background to old habits: When developing HTML5 music to play Ria, miss Ben found a strange problem in IOS Safari: 1 //CodeThe premise is that zepto. JS is referenced.2 VaRAudio = $ ("audio") [0];3Audio. src = "testaudio";4Audio. BIND ("tap ",Function(E ){5 Audio. Play ();6}) The zepto tap is invalid !!! What's going on? After a lot of breakpoints are added, it is found that the TAP event is not invalid, but the audio in the call

that WebService is still required or Asp.net can be used through dataset XML, and no attempt has been made. Finally, e is invisible on the interface.I suddenly found that my layer tree can only display the layer name, but this can't be done. How can I say that layer control and menu are still required? How can I implement TOC, see the ArcIMS WebGIS path of flex RIA in the next phase -- flex custom control implementation layer TOC PS: in fact, this is

Data cannot be retrieved from the database when the code, compilation result, and database are determined to be normal. Error prompt: sysyem. net. webexception: the remote server returns the error notfound. The Listener finds that the requested Database Service is abnormal and the access address http404 is incorrect. An error occurred while initiating a request to the database. Error message after access to SVC address After confirming that the other aspects are normal and the VS is fixed, t

Generally, you can set the Timeout attribute value in the configuration file to customize the service Timeout time. However, the WCF Service does not have a configuration file, and the default Timeout value is 60 s. But sometimes, if our query time exceeds 60 s, can we define the time-out by ourselves. The answer is yes. The proxy class generated by RIA Services is just partial. We can use this to set timeout. First, create a class WcfTimeoutUtility i

In. in the development of net Ria Serivce, we often see that when operating data, some controls will often jump to a client's data verification exception breakpoint, and these breakpoints are often not what we want to see, this makes development debugging unnecessary. Here I will describe how to make this exception no longer appear when debugging Silverlight. I set debugging parameters in vs to achieve the goal. Exception: Solution: 1) menu> deb

The Silverlight + WCF Ria service is still lacking in enterprise business systems such as ERP, and there is a lot of trouble for clients to call synchronously. The server automatically generates client entities and proxy services.CodeYes, it looks beautiful, but it is not very useful, and it is not conducive to splitting. There are several databases. It is very difficult to maintain the public entities together because the common entity is generated a

[dbo].[Department] AS[Extent1] As you can see, EF only queries two fields for us. Also, EF does not automatically correlate data for course tables for us.Note that in this code, we first select New with an anonymous type, bypassing the dbsetThen, we will find that we cannot get the data, trace the error, and we will find:{"The Entity or complex type ' schooldata.department ' cannot is constructed in a LINQ to Entities query."} system.systemexception {System.NotSupportedException}The

loaded to the client. This is suitable for most application scenarios. In other cases, we can solve the problem through DomainCollectionView. DomainCollectionView In many enterprise applications, tens of thousands or even millions of data records are sorted, filtered, and grouped. ICollectionView is no longer applicable to such scenarios. The reason is described above. We need a set that allows the server to sort, filter, group, and more important paging operations. This is the responsibility

Deploying WCF Ria services in IIS6 is simple, but some problems may also occur. Our application is Silverlight 4 business application, which applies the WCF Ria service and. NET Framework 4 environment, so we encountered some problems. The main environment involved is Windows Server 2003 R2/Enterprise Edition, which is deployed when Visual Studio 2010 is not installed. After installing. NET Framework

Silverlight is a heavyweight product of Microsoft in the RIA development field.

That is, its login function, which has been written before, can also run normally. But ..

Ria is short for rich Internet applications.Program(Macromedia Chinese website translation for rich Internet applications) Traditional network programs are developed based on pages and server-side data transmission modes. The presentation layer of network programs is built on HTML pages, while HTML is suitable for text, the traditional page-based system has gradually become unable to meet the higher and all-round experience requirements of network v

This error is often returned when you use Silverlight to call remote WCF Ria service across domains: the remote server returned an error: notfound. This error cannot be debugged. What should I do? You can enable the tracing function of the WCF Ria service, record the trace file, and view it using Microsoft Service trace viewer. Add the following content to the Web. config of the WCF

Address: http://www.cnblogs.com/Realh/archive/2011/06/30/2094019.html Wcf ria is an interesting technology that allows clients to directly access the database on the server without creating a new WCF project (of course, its underlying layer is implemented through WCF ), just like operating a local database. However, WCF Ria can only be used for Silverlight. The related installation packages are in
