Hi,
I'm working with VB.NET Visual studio 2012 Ultimate.
I designed a report via the ReportViewer. When I Initially setup the report, I entered as the Data Source, a Class Name from an Object that I developed in a DLL. I was able to select the Property Names of the data from my Object in designing the Form.
However, at run time, I want to change the data source to the instantiated object from my DLL.
Example: This is the Class in my DLL (only used as an example - not my actual code)
I built the class into a DLL called MyClass. From my VB.NET Windows Forms App, I can instantiate the object and successfully access the properties.
This code in my client module returns "George Washington"
dim objA = New MyClass
msgbox objA.MyName
Next, I setup the ReportView with a logo and I entered "MyClass" as the Datasource to my report. On the report I dragged the MyName property to the report designer.
However, when I run my module, "MyClass" is not instantiated and does not appear on the report. I tried this to reset the datasource at run time:
But apparently I can't set the datasource to an object that is not a table????? Is it possible to set the datasource of my report to an object that I instantiate in my program at run time?
Thanks for any help ....
