Question : Get the values of a cell in a selected row of a RadGrid on client Side

Hey there everyone, I'm hoping there is a simple fix for this, but I would accept a complicated one after messing around with it for the last day and a half!

I am putting together a module that will drop into a DotNetNuke portal and I'm populating a Telerik RadGrid with data. I have followed every tutorial and example I can find, but the result keeps coming back with "object Object", "null", or "undefined".

I need to:
1) get the value of the "BookingID'" column for each row that is selected
2) pass the value into a url string that opens up in a RadWindow.

I'm trying to do all of this using javascript, but if you know a better way, I'm down for anything at this point.
Here are some of the tutorials and examples I have followed to no avail:

Here is my current JavaScript and a stripped down radGrid:

		alert('window.radopen("/Default.aspx?tabid=" + tab + "&ctl=multiEdit&mid=" + mid + "&BIDs="' + id + ', "RadWindow3");');
		//if(id.length>0) {

		//}
