Using the Space Bar

The space bar allows you to toggle selected items check state with a single hit. Pressing space bar selects current item if it is not selected. When current item is selected and the space bar key is pressed there are two cases:

  • Toggle selected items, if all items CheckStates are equal.

  • Check selected items, if at least one item has different CheckState. checkedlistbox-features 001

  4. Toggles selected items CheckState.
