Would it be possible to add to RadSlideView property "SelectedIndex", that could be databound to SelectedIndex in our viewmodel using TwoWay binding? Just like this property works in ItemsControl. Right now we cannot use for twoway binding the SelectedItem property.
Thanks.
Thanks.

Hello Mirko,

Thank you for contacting us.
What prevents you from implementing a SelectedItem dependency property in your view model?
An approach that comes to mind would be to bind the RadSlideView's SelectedItem property to your view model's SelectedIndex and use a converter. All you have to do is make sure you have a reference to your collection in the converter.
Let me know how I can be of further assistance.

In our viewmodel we use as reference collection of items for OneWay binding, and SelectedIndex property for TwoWay binding + read only SelectedItem property. I guess we can work around this issue, although having the possibility to use twoWay databinding either using SelectedItem or SelectedInex will be easier for us.

Thank you for the follow-up. I've added your request to our backlog. We'll consider implementing a SelectedIndex property for future versions of RadSlideView.

Hi, are there any news about the implementation of databindable SelectedItem property on RadSlideView? It would allow us to remove some workarounds from our code, that we use right now.
Note that both SelectedItem and SelectedIndex supports two-way binding on built-in controls like ItemsControl, ListBox and others as well.

Hi Mirko,
The SelectedItem property supports binding expressions. Could you please share with us what types of workarounds are you using regarding this functionality so that we make sure no issues are present currently?
There is no SelectedIndex property exposed by RadSlideView that can be used in binding expressions.
Looking forward to your response.

Sorry, I meant support for SelectedIndex databinding in Telerik controls.
Most of our view models uses SelectedIndex as the main property for two-way bindings, so in case of Telerik controls we have to use manual SelectedIndex propagation in SelectionChanged event handlers which is less convenient than just using two-way databinding.
To be more precise, it would be great if RadSlideView (and any other control with list of items and selected item) was a child of the Selector base class, just like similar native controls (ComboBox, ListBox, FlipView, GridView, ListView), rather than just based on Control.
