Using custom parameters for rendering extension

[Charles]

I've successfully put together a custom extension by using IRenderingExtension and I'm able to choose the option from the dropdown, select export, and get results in a format that I need. I've added parameters to the new extension in the web config, but I can't find them when I debug. They don't seem to be within the report, renderingcontext, or deviceinfo variables. I even just tested out with simple names and values such as "test". Is there something I'm missing?

 

Thanks,

Chuck

Hello Charles,

Have you added the appropriate ExtensionParameter attribute to your renderer class that implements IRenderingExtension.

Here is an example:

[ExtensionParameter(ImageReport.OutputFormat, typeof(string), "TIFF")] // Values: BMP, EMF, EMFPLUS, GIF, JPEG, PNG, TIFF, PDF

[ExtensionParameter(ImageReport.TiffCompression, typeof(string), "")]
public class MyRender : IRenderingExtension
{
.....

We will appreciate if you elaborate on your scenario and what kind rendering extension you had to implement.

Thanks for getting back to me, Peter. I'm going to be customizing the output into a CSV format. What ​is the namespace for the ImageReport class that you're referring to?

Hello Charles,

The fully-qualified name of the class is Telerik.Reporting.ImageRendering.ImageReport.

I hope this helps.
