ClearSelectionButton event?

[Dave]

I've got a few RadComboBoxes on a search form that utilizes the ClearSelectionButon quite nicely.

I've now been requested to make those ComboBoxes be multi-select.

I've test-driven all 3 examples I found and am partial to this one:

However, the next obvious question then becomes how to use the ClearSelectionButton in this scheme.

I tried adding it in, just to see if somehow, magically, it would work, and while the button shows up just fine, it doesn't do any clearing.

So then I searched to see if I could find an event I could grab to do the clearing myself... and have not been successful.

I'm running Q1 2012 SP1 right now.

Any help would be wonderful, thanks!

Hello Dave,

This is not supported out of the box. Nevertheless you need to edit the ComboBox template so you can gain access to the Clear Button. You can find a simple implementation as an attached file, also I have attached another project which uses a check box to select or unselect  all. It might be worth considering implementing your own Button.

All the best,
