    Hello.

    I wonder if Telerik have some controls which can play the role as TreeView with checkboxes for Xamarin Forms ?

    Hi Yor,

    At this time, UI for Xamarin Cross-Platform does not have a TreeView component, although we have approved the development of such a component in a future release (you can add your vote to it here).

    The ListView does support MultipleSelection mode, which will render checkboxes on some platforms, but it doesn't support nested tree data with selection for the nested items. If the nesting isn't critical, you can flatten the data by Grouping it and using the DelegateGroupDescriptor.

    Please let us know if you have any further questions.

    Hi Vaibhav,

    My response to Yor (below) was approximately a week ago and the status has not changed. You can always check in on the status of the feature request by going to this "Add TreeView to UI for Xamarin" feedback item in our feedback portal.

    Note: You can "like" it to increase the priority of the item.

    Currently the feature is in the green "Approved" stage, you will see it change to an orange "Under Development" stage when we've begin working on it. When it has been completed and has added to the suite, you'll see it change to a blue "Completed" stage.

    How are we able to prevent the rendering on the checkboxes on some platforms for the radlistview?

    Hi Eric,

    At this time, removing the multiple selection checkboxes is not an option available on the RadListView. We've designed the control to meet the platform guidelines, where on iOS such guidance is to show a checkbox (or similar toggle-able indicator) when in multiple selection mode.

    I recommend opening a support ticket here and ask the dev team if there is a way to access the cell's CheckView from a custom ListViewRenderer so that you can hide it. You also want be able to still show the user that row is selected, so you'll need to update the BackgroundView's coloring when an item is selected and deseletced
