ButtonGroup, I would like to have a third SelectionMode for the ToggleButtons in the group

Currently we have 2 SelectionMode to select from in the ButtonGroup. I would like to have a third option that is a mix betwen Single and Multiple.

This third option should work like the Multiple mode but don't allow the user to deselect all ToggleButtons, like in the Single mode at least one button is allways selected. If the user clicks on the last selected Togglebutton he will not be able to deselect it.

Hi Thomas,

Thank you for getting back to us with feedback.

You can reduce the repeating SelectedChangedHandler code by extracting it in a separate method. If you want to make things even more compact, you can extract the whole TelerikButtonGroup into a separate reusable component.

Currently, the desired behavior is easily achievable, and a built-in feature does not seem needed. That said, at this stage, I confirm that both selection modes remain - "Multiple" and "Single".

Hi,

Yes it is possible by doing it like that. But the whole point of using a component instead of doing it all by my self is to reduce the code I need to write. I would like to use the ToogleButtonGroup in MANY places with 4-5 button each time and I don't want to repeet that code every time I use the Toogle Button.

 

So yes, it is possible but then it will instead create my of ToggleButtonGroup instead of use yours. That is why I whanted this feature.

Hi Thomas,

I confirm that the desired functionality (mixed selection mode) is already possible by using the SelectedChanged event of the component.

Here is an example I have prepared - REPL link. You can run and test the REPL sample to see the result.

In short, the idea is every time you deselect a button, check if it's the last selected in the SelectedChanged event handler.
