How to auto-select with checkbox tapped item?

[Seznam]

Hi,
there is difference between the native Windows Phone implementation of checkboxes in list and Telerik DataBoundListBox.
When I click in the WP Email app the empty area on the left next to an email, the checkboxes shows up and the tapped email is selected.
In DataBoundListBox only the checkboxes shows up and I have to tap again to select the item.
Also if I deselect the last item in Email app, the checkboxes disappear again, in DataBoundListBox the checkboxes stay there.

Is there a way how automatically select the tapped item when showing the checkboxes and also how to simply deactivate the checkboxes when deselecting the last item?
Thanks

Hello Martin,

Thank you for the question.

You can use the IsCheckModeActiveChanged event to detect when the checkboxes are being displayed and add the tapped item to the CheckedItems collection. With the ItemCheckedStateChanged event, you can see when an item has changed its checked state and if the the CheckedItems collection is empty, you can hide the checkboxes. I have attached a sample project for demonstration.

I hope this helps. Please, let us know if you have further questions.

Hi,
thanks for the reply. I've implemented it this way and it works fine.
It will be probabaly useful to add this hint to RadDataBoundListBox web documentation as well?
