Hi Nathalie,
Thank you for contacting Syncfusion Support.
We have prepared the sample with updated code example and tried to reproduce the reported issue "Syncfusion TileViewControl is not shown" but we were not able to reproduce this issue. In this sample, we have bound the StaticResource key to DataContext instead of AdapterBinding. Please download the sample from the below link.
Sample:
TileView_HiddenYou have used AdapterBinding to bind the DataContext in your sample. So, could you please share your application with AdapterBinding and more details regarding this. It would help to proceed further.
Regards,
Marimuthu S.
