Convert Dynamic Entity to Entity (kbarticle)

(0) ShareShare
ReportReport
Posted on by 615

 Hi All,

 I have a plugin that is set up on the kbarticle entity and is triggered by the update event.  I am able to get the Dynamic Entity from the  context using the following

 

Dim de As DynamicEntity = CType(context.InputParameters.Properties("Target"), DynamicEntity)

 

Now what I need to do is  convert or cast this Dynamic Entity to the business entity type kbarticle.  Can I do something to convert it or do I have to use the guid and then use retreive via the crmservice?

 

Thanks,

 

Russ

    Hi Russ, you can do it this way http://msdn.microsoft.com/en-us/library/cc151177.aspx

     I think the general concept is to deal with dynamic entity when using the dll's as opposed to the web service and as the plugins utilise the sdk dll's I would recommend staying with dynamic entity if you can. Is there a specific reason beside having a nicely typed class that you are trying to convert to a core entity? I also think the sdk dll crm core types are depreciated in CRM 4 but I'd have to double check that.

     Hi Rhett,

     For some reason when I tried to get the properties of the dynamic entity there were only 2 of the many that the entity has.  I was bale to get the GUID and then use the code below to retrieve the kbarticle and get the rest.   Thanks for the help.

     

    Dim de As DynamicEntity = CType(context.InputParameters.Properties("Target"), DynamicEntity)

                    'get the kbarticles guid from the property bag
                    Dim kbGuid As Guid = Nothing
                    For Each p As KeyProperty In de.Properties
                        kbGuid = p.Value.Value
                        Exit For
                    Next

                    'lookup the article using the service and the kbarticles guid
                    Dim service As ICrmService = CType(context.CreateCrmService(False), ICrmService)
                    Dim kba As kbarticle = CType(service.Retrieve(EntityName.kbarticle.ToString(), kbGuid, New AllColumns()), kbarticle)

    The input parameters will only pass through the values that changed on the form. You can register a Post Image for the plugin step and select the attributes you want from there.

     Instead of using context.InputParameters.Properties("Target"), you will use context.PostEntityImages.Properties("PostImage") when you register a post image against the plugin step. You can call the post plugin step what ever you want but I have named it PostImage here,

    I will give this a shot and let you know how it goes.  Thanks Rhett!
