The solution what I'm looking for shouldn't require to instantiate Class object. 回答1: It won't be a proper binding (which is not necessary for static data anyway) but you can easily create a MarkupExtension to retrieve it, just pass the type and the property name

问题 So I have a problem where I want to pass data around my application in what I thought would have been a very standard way, but I'm unable to find any samples or examples that are similar to what I want to do.

问题 Quick question, In Xamarin Forms, when using a Tabbed Page, is there any way for there to be content that remains static between the tabs (other than the tabbar itself)? For example, if I have a TabbedPage with 3 children (say Page1 , Page2 and Page3 ), can I add other children to TabbedPage that are not a part of the tab itself, but elsewhere, and stay there between tabs? My use for this is I have 3 tabs in my TabbedPage , which is are at the bottom of the page. I would like a settings

问题 I'm trying to get the dialog in DialogHost to be horizontally stretched as much as possible, without hardcoding the size of the control that I'm displaying.

Is there some standard

问题 I have a window that will be a variable size , currently it is 300 x 400 as shown below. In the top part I have an expandable tree view In the bottom part I have a long horizontal panel with a button in it. I want the top area (treeview) to be about 95% of the height, with the button tool area a constant 50 high. I want these proportions to stay constant as the user expands and collapses the tree view (and as it expands below the button toolbar, I want the viewscroller to pop in with a
