How to check if a grid row (any row) is selected??

Not which row is selected, but if any row in general is selected. I have a delete button on grid tbar which uses SelectionModel(). But in the event user launches grid and clicks delete button, this will throw an error since no record(row) is selected. So maybe I can check to see if a row is selected and only then enable the delete button or something. Normally would be no biggie but this will be going in to testing phase soon.



Need a quick response, thanks!
