Question

Is there any way to force a listview control to treat all clicks as though they were done through the Control key?

I need to replicate the functionality of using the control key (selecting an item sets and unsets its selection status) in order to allow the user to easily select multiple items at the same time.

Thank you in advance.

It’s not the standard behaviour of the ListView control, even when MultiSelect is set to true.

If you wanted to create your own custom control you would need to do the following:

1. Derive a control from ListView
2. add a handler to the ‘Selected’ event.
3. In the ‘OnSelected’, maintain your own list of selected items.
4. If the newly selected item is not in your list, add it. If it is, remove it.
5. In code, select all of the items in your list.

Should be simple enough to implement and feel like multi-select without using the control key!
