Usage example

Let's take as an example the EventDay sample KB and see how different values of the Selection Type property changes the behavior of a row when it is selected. For instance in the Sessions Grid at the List level of the WWSD Session:

Using the Auto Deselect value the Highlighted Background color is shown only when the user presses the row, after that the row is deselected automatically:

Using the Keep Selection While Executing value the Highlighted Background color is shown until the Default Action ends:
