Executing unit test methods Visual studio after selection from test runner

I have created a UI where i shows all test methods (list1) user can select multiple test methods on execution list (list2)

[ASK]

I need some pointer on how to call multiple test methods based on user selection at list-2. Test methods are available under three diffrent classes. On click on "Execute" button, selected test methods should get called. Also i wanted to show test result/log messages on screen (on a label)
