I tried uninstalling and re-installing the Telerik Reporting module, but still have the same issue. See attached screenshot from the application. I also verified that my Application.xaml has the Resource Dictionaries:īoth the VS designer and my application show the control as completely blank and transparent. I dragged and dropped the report control to let it create the references. I've verified that I have references to both Telerik.Reporting and, and I verified that the References are set to copy local. However the Visual Studio designer shows the ReportViewer control as a completely blank and transparent object. I've made it extremely simple just to test things. To display the report I have a custom control that hosts the Telerik ReportViewer and passes the ReportSource via DataBinding with a DependencyProperty. RsTelerik.ReportDocument = rPack.UnpackageDocument(New MemoryStream(MyByteArray)) My application handles the uploading of the report document and pulls it from the database and generates a before showing it.ĭim rsTelerik As New ĭim rPack As New Later on I plan on adding data sources and binding those to internal system objects. To test, I copied the sample Invoice report, and removed all data sources and everything except a simple line of text and image to make sure it renders.

My application stores the reports as a byte array/varbinary in an MSSQL database. I'm trying to use Telerik Reporting to do this, much like other applications use embedded Crystal Reports. The user creates the Purchase Order, then needs to print it. In my application, I need to allow users to generate printed documents from system objects.

I'm using Visual Studio 2017 v15.9.38 along with Telerik UI for WPF and Telerik Reporting v 15.2.21.915 (latest version). I'm having a problem using the Telerik Reporting WPF ReportViewer control.
