I have the free Audacity audio file editor program. When you load in an audio file, the program displays a waveform of the audio. You can mark an area on the waveform by clicking on the wave form with the cursor and draging the cursor horizontally. This causes the area you selected to have a darker background. It looks like a selected block. (See attached screenshot.)
Once you've done that, you can also position the cursor on either end of the block to drag that edge of the selected portion back and forth to resize the area.
I need to implement a similar feature in my own application, with the added requirement of being able to select more than one area on the waveform at one time.
Anyone have any ideas on how I might go about this using Telerik .NET forms controls? Maybe positioning some kind of partially transparent object over the waveform?
Thanks for any suggestions.

Hello Mark K.,
You can achieve the desired behavior with the help of RadPanels. I am attaching a sample project which demonstrates the how you can implement semi-transparent RadPanels. However, the rest of the scenario is custom and it will require some implementation from your side.
If you have additional questions, feel free to contact me.
Kind regards,
