Error with Telerik Reporting objectdatasource with MVC

[nikky]

When trying to use Telerik Report Wizard to connect to an objectdatasource, I get the error "An error occurred while invoking data retrieval method"  Try restarting VisualStudio."

Please can someone help me troubleshoot this. I am using version Q3_2012_v6_2_12_1017.

Thanks.

Hi NIkky,

We will need some additional information about your issue since we are not able to reproduce it at our end. For example you can provide us with a step-by-step guide on how to reproduce it.

Other than that you can try actually restarting Visual Studio, since this is the actual problem in most cases and doing so will resolve your issue.

Thanks IvanY  for the reply.

Here are detailed steps of what I am trying to accomplish.

I am working on Windows Server 2003 R2 and Visual Studio 2010. I have an MVC web application on the machine. I installed "Telerik_Reporting_Trial_Installer_Q3_2012_v6_2_12_1017.exe" on the server and the following references:

1. Telerik.Reporting
2. Telerik.ReportViewer.WebForms

I then added a new "Telerik Report Q3 2012" report to the solution. When the Telerik Report gets created, I get a Telerik Report Wizard Screen. I hot "Nest" on the screen. For next screen, I select "New Report" and click on "Next". Then on the 3rd screen when I try to add a new DataSource, I select Object Data Source and access the function from one of my DataAccess classs file. As soon as I select the business object and the data member and click on "Finish", I get the above error. The data member has a simple function to access the database and retrieve information from a table.

I have already tried the following with no success:

• Restarting Visual Studio
• Restarting machine
• Re-installing the software
• adding connection string to the data member function "Data Source=MACHINE1;Initial Catalog=TEST;Integrated Security=True"

Please let me know if you need any other information.

Hi Nikky,

Since we were not able to reproduce your issue following the steps you have provided it will be best if you can open a support ticket and attach a sample report that reproduces it so that we are able to view/debug it at our end - this will help us identify the culprit faster and advise you more accordingly.

Hi,

 

I have the same error.

I have add a new datasourceobject to the report and then I can not use the preview anymore.

Please see the attached file.

Perhaps the solution is simple.

Hello Simon,

You might check the answer from Stef on the same topic here. Alternatively, you can try restarting Visual Studio, since this is the actual problem in most cases and doing so will resolve your issue. 
If the issue still persist, please open new support ticket and send us a sample report that reproduces it so we can check its settings.
