❔ Need help on UI Design and tips for implementation - .Net Maui

three questions: 1. How can I edit the blue bar on the top? I'm not sure where its coming from, I only know that Home is the Route of one of the FlyoutItems, But I want other things in that blue bar, not the FlyoutItem's Route. Ideally I would like to have an image there from our Company. How can I define my own DataTemplate if necessary for that blue bar wherever its coming from? 2. It's very likely that certain dataGrids of the ones you see here will not contain any data. What to do in that case on the UI? One way would be to display a message in the DataGrid that there was no data. But I would prefer to just not display the DataGrid at all in that case and have the others fill out the respective size instead. I'm not sure how to achieve that other than dynamically instantiating or not instantiating Grid Rows in code-behind based of whether there is data , which I want to avoid. I would much rather just use my xaml without much code-behind if possible 3. We are using a WebView on the Window. In the App I am migrating from WPF to Maui currently - we had a toggle switch at top left corner which would switch between two URLs for the WebView - one specific ticketsystem of a certain customer and the other is a Shared Service Desk that is being used for all other customers. I'm not happy with that approach but have no idea how to do it better. Any guidance? The reason why I don't like it is because its not expandable. There might be more customers in the future with other Ticketsystems, and now we got more than just two urls to switch between for the webview and its hard to add any.
