Visual Studio Report Designer is Blank

Environment

Description

On opening a CS/VB report in the VS Designer, the report is blank. If the VS Report Designer is blank, this indicates that the report's InitializeComponent method cannot be accessed and read.

Possible Causes

1. The created class inheriting Telerik.Reporting.Report does not have a default parameterless constructor in which the InitializeComponent method is called.
2. In rare cases, usually when working under source control, the report's files are disassociated - Visual Studio does not recognize the Report's CS|VB, Designer.CS|VB and RESX files as a whole. This condition can be recognized by testing to navigate to the definition of the InitializeComponent method from the report's constructor.
   

Solution

1. Check whether the report class has a default parameterless constructor and add such, if needed. Verify that the InitializeComponent method is called in that constructor.
2. Verify thatTelerik Reporting is installed on the machine, and the Telerik Reporting* assemblies are referenced in the project. Then exclude the report files from the project and re-add only the report's CS|VB* file. Visual Studio should auto-detect the related Designer.CS|VB and RESX files.
   

Notes

You may exclude many reports at once, but re-adding reports must happen adding one by one separate reports' CS|Vb files.
