I have enabled the parameter area in the report (HTML5) and was able to render custom controls, but it is not wide enough. I want to increase the width from 15em to 22em.
I have tried to update the css of the telerikviewer to 22em, but then the report area slides under the parameter area. I haven't found what is calculating the width of the report viewer itself. Is that done in javascript, or described in css.
Can you help me how to increase the width of the parameter area?
