I am doing GIS development using ArcGIS Runtime SDK for .NET. Version 10.2.5. It is a WPF application, which have multiple tabs and each tab contains Map control. Map control is embedded as a WPF user control and data source is set using MVVM binding. When I switch from one tab to another the Map disappear.
While debugging I notice the data source (model) has all the data (layers and graphics) , but the map doesn't show the basemap and layers.
I have tried options/ solutions provider by various blogs and Esri help but nothing is working.
See attached screen shots.
I will appreciate your help if you could provide me few pointers to solve this problem.
