Question

I have an MS ReportViewer report that is bound to a datasource, that is requesting a property that it shouldnt. I have checked all of the fields on the report and I cant find anywhere its used.

Putting a break point on the property shows its definately being called, but I cant find out from where as its the ReportViewer is making the call.

****Is there a way to find out where this property is being called from?**

Here is what I have checked so far:

Stack Trace: shows managed code, checked the disassembly but couldn’t see anything obvious.

Call hierarchy shows all the places that property is called from – none of which are on the report.

Update:

Tried n8wrl’s suggestion of throwing an exception, but the stack is still on unmanaged code.

Update 2

I have also tried adding Xml and Script ignore tags in case the object as being serialized somewhere but that didn’t work (unless they are not the correct tags to ignore serialization?)

Answer 1

Ok, I have come up with a solution. I assumed this had something to do with serialization so I passed the datasource in to a System.Web.Script.Serialization.JavaScriptSerializer.

When serializing the object I found all of the properties that were causing the code to bomb out. I added [ScriptIgnore] tags to these properties to stop them begin serialized as they were not used.

System.Web.Script.Serialization.JavaScriptSerializer serializer = new System.Web.Script.Serialization.JavaScriptSerializer();

serializer.RecursionLimit = int.MaxValue;

object o = serializer.Serialize(base.CurrentOrder);
