Error while passing large data from RIA service to Silverlight

Question

Hello All,

 

When passing large data from RIA service to Silverlight , the load operation failed with an exception.

Can anyone tell me how to

1.  Increase the  reader quota  values

2.  Custom binding binary message encoding  for RIA service in the configuration file at server side(web.config) and  Silverlight application( there is no .clientconfig file for RIA)

3. Change binding configuration to pass more records

4. Increase idle timeout of RIA service which is deployed in cloud with authentication="none" & ADFS integrated.

 

I think answers to these questions will help solve my problem.

 

Thanks,

Deepthi

Answer 1

I have very same problem with RIA services.

I need to retrieve big chunk of data and I can not increase buffer and message size limit in client side.

Appreciate any help.

Thanks.

Answer 2

something like this in your web.config ?

    <behaviors>
      <serviceBehaviors>
        <behavior name="Project-Web-MyDomainServiceBehaviour">
          <serviceMetadata httpGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="true"/>
          <dataContractSerializer maxItemsInObjectGraph="2147483647"/>
        </behavior>
      </serviceBehaviors>
    </behaviors> 

change the name of the behaviour to your projects domain service behaviour name

Answer 3

I tried it but it didn't help.

The problem, I think, that I need to configure receiving data in ServiceReference.ServiceConfig file (client side) as well as sending data in Web.config like you show above in service side but I can not create ServiceReference along with ServiceReference.ServiceConfig file since I use RIA service.

Thanks.

Hello all,

Now it works for me.

Code from the last post didn't work until I configure behaviors section like this:

     <behaviors> 

         <serviceBehaviors> 

             <behavior> 

                 <serviceMetadata httpGetEnabled="true"/> 

                 <serviceDebug includeExceptionDetailInFaults="true"/> 

                 <dataContractSerializer maxItemsInObjectGraph="2147483647"/>  <!--this is important-->
  

             </behavior> 

         </serviceBehaviors> 

     </behaviors>

 

Thank everybody.

Answer 9

Irina,

While the solution above by itself did not work for me (pulling 3400+ records into my Silverlight app via WCF RIA), setting the maxItemsInObjectGraph for dataContractSerializer did work just fine.  Thank you for the solution!
