Hi - I've created a UltraListView that in the Group Headers a CheckBox is displayed and when this checkbox is selected then all the items in that group are selected automatically. Works fine. I use the IUIElementCreationFilter to create the checkboxes.
What I would like to do is allow the user to double on the Group Header and then automatically check all the items.
The double clicking on the group header allows for a bigger target than the small checkbox that is available. I have no problem with itemDoubleClick and I would like the Group Header to function the same way. I'm using VB.NET Basic if you have any code that you can pass on.
Thank you for your time and look forward to your help.

Thank you for contacting Infragistics. UIElements don't appear to have double click events so I think you are going to have to track that manually.

I attached a sample based on your requirement using a single click.
