exception has been thrown by the target of an invocation report in telerik when add datasource

[Tejas]

I am trying to my first telerik report and when trying to add datasource on report I am getting error says "Exception has been thrown by the target of an invocation "

I am using entity data source.
I chanaged procedure 10 times with diffrent conditions and finllay I return dummy row but still same error. It works for other procedure ...

I do not undestand what is the issue.

Hi Tejas,

Currently when EntityDataSource component is used the EF Model should be located in a separate class library in order for the report designer and the report wizards to work properly. Additionally you will have to copy the connection string to the App.config file of the report class library, so that Entity Framework can find your database at design-time.

This limitation is caused by Visual Studio Type.GetType and we have to further investigate the issue and undertake appropriate actions.

Please excuse us for the temporary inconvenience.

Kind regards,
Peter
