Discussion

The onKeyDown event fires when the user presses down a key on the keyboard when a control has focus. It is the first keyboard event to fire when the user presses a key. This event can be used to execute an Action Javascript, custom JavaScript, or server-side Xbasic to perform an action. For example, when filling out a text control, you may want to automatically save the Grid row when the user presses the Enter key:

// Submit the Grid Row if the Enter Key has been pressed
if (event.keyCode == 13) {
   // Enter key has been pressed

   // Simulate clicking the SAVE button for the row:
   {grid.object}.submitGridPartRow({grid.rownumber});
}
