RowSelectorColumn of MetaBuilders

I was revising a page where a user selects an item from a grid and does a very intensive processing.  User can select a number of items from the grid, since it uses a checkbox column and since it performs a very intensive processing i decided to switch it to a single select grid using radiobutton.  Another issue was it was kind of difficult what to present in the UI if an error occurred in one of the items, do i halt the processing of all the other items, do i rollback the previously processed items, etc.  In other words, keeping things simple.

As I was revising it to a radiobutton, I discovered that there was an issue on the gridcolumn as radiobutton not performing a singleselect and you have to do your own scripting to handle that.  I remembered my teammates discussing an issue before with radiobutton and this was it, he could not restrict the user to select just a single item.  I bumped into a set of free controls of metabuilders (www.metabuilders.com) and decided to use RowSelectorColumn instead since it is free.

I really wanted to develop ASP.NET controls like this and before I can do that, I really have to buy this MS Press Developing ASP.NET Server Controls and Components.  DataBlitz Megamall has a copy but it is still on P3,000, in amazon.com, it is currently at P2,000.  Maybe I should talk to manager to lower the price, hahaha.
