    Telerik Product and Version

    Telerik Reporting 2018 R2

    Supported Browsers and Platforms

    Components/Widgets used (JS frameworks, etc.)

    (I first posted this as a regular thread under Reporting and after a few inquiries I decided maybe it needed to be in the code library. Original post is here: ) I looked for  a long time for this information. I watched YouTube videos, went to blogs, and contacted Telerik support. I decided when I figured this out I was going to post the code so that someone else would not have to struggle with figuring this out like I did. Support helped and pointed me in the right direction to put this together but no easy example to go by. Below is the code for the HTML5 Report Viewer that I use and seems to work exactly like I wanted. It is javascript that parses the URL string and then is fed to the parameters of your report. The only part of this that you should have to change is the the section that is called "reportSource:" the parameters section. In the example below change the first part "TransMonth: " to the name of the parameter you used in your report and change the name at the end to what your URL parameter is called " getParameterByName('TransMonth') " Mine were named the same for simplicity. See the entire code below. Also some of the js and css files have custom paths in the example below. Adjust yours accordingly. I'm far from an expert at this but I know it took me a while to get this working and I thought if I could save someone else this headache I would. Also there are some attached images of setting your parameters on your datasource and your report. They must all be set for this to work.
