Question

I have a weird situation.
I have a longlistselector with MVVM databinding. When one item get’s selected, I change the colour of the text to the phone accent colour. But the item doesn’t change its colour on the screen. ( even not when I scroll in the list )
If I then just switch to another page and come back, the item colour is changed if I scroll to it if it is not visible. If it is visible, it still hasn’t changed colour until I scroll it out of view and back into view, then the colour will also change.

Anyone the same experience?

If you’re changing a bound value but it’s not being reflected in the UI then this will typically indicate that you’re not correctly notifying of the change. Make sure you’re implementing INotifyPropertyChanegd on the viewmodel and calling RaisePropertyChanged appropriately.
