Hi Sharath,

Easiest (and best practise) is simply to put the code for what to do on Button click into a seperate method (say OnOkClicked), then call this method from the Button Click event handler, as well as at the end of the ListBox DoubleClick event handler.

I nice pattern to implement is to implement an ICommand (like Josh Smith's RelayCommand - google it) on your modelview class, bind the button's Command property to it, and then in the list box's DoubleClick handler, invoke the Executed method of the command. This strucutre simplifies maintaining the logic of:

1. If nothing is selected in the list box, disable the OK button (Command.CanExecute would return false)
2. If something is selected in the list box, enable the OK button
3. If the list box is double clicked, select an item and invoke the OK command.

Hope this helps.

you can make your own control and implement ICommandSource which will give you the same properties
