Hi have a requirement to generate a grid of photos.  

I have managed to get the data in the shape where this can be grouped in a cross-tab.  The photos I need to bind to have a filename of {id}.jpg in a known folder.  I have created a user function that accepts the Fields.Id, retrieves this photo and returns an image (this is a technique I've used before successfully).

I have added a picturebox into the detail of the crosstab, but whenever I go to bind the "value" of the picturebox to the user function, Visual Studio crashes.  Stack trace below.  I suspect as this is in the detail it's trying to apply some aggregate to it.  Are there any workarounds to do this binding at runtime to get around this designer bug?

 

Application: devenv.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.ArgumentNullException

Please close this, it only falls over in the expression builder, typing the binding in manually works fine.

Hello Graham,

If you are using Telerik Reporting R1 2017 or newer, please test to upgrade to the latest available internal build v11.0.17.323 . The MSI can be downloaded from your Telerik account - Downloads - Reporting (version:11.0.17.222) - Latest Internal Build.

Regards,
Stef
