You can find the source code for the entire online Telerik Examples app on your machine. Locate the Visual Studio solution at:
C:\Program Files (x86)\Telerik\RadControls for Silverlight Q2 2013\Demos
Open it in visual Studio and in the Solution Explorer drill down to the Docking folder. You'll find the different examples there, including the "First Look" demo.
If you don't see that file path on your machine, that means you chose not to download the "Local Demos" on your PC when installing the Silverlight controls. Simply do the following:
- launch the Telerik Control Panel
- choose RadControls for Silverlight
- check off the "Local Demos" checkbox
- continue with the steps to finish up
Once that is complete, you'll find the solution where I mentioned earlier. You can also use those steps for other product demo source code.
