The Button usually displays a short text string indicating a command, but it can also display a bitmap image, or a combination of text and an image.

The user presses the Button with a finger or clicks it with a mouse to initiate that command. Most of the topics discussed below correspond to pages in the ButtonDemos sample. Button defines a Clicked event that is fired when the user taps the Button with a finger or mouse pointer. The event is fired when the finger or mouse button is released from the surface of the Button.

The Button must have its IsEnabled property set to true for it to respond to taps. The BasicButtonClickPage. The Button tends to occupy all the space that's allowed for it. For example, if you don't set the HorizontalOptions property of Button to something other than Fillthe Button will occupy the full width of its parent.

By default, the Button is rectangular, but you can give it rounded corners by using the CornerRadius property, as described below in the section Button appearance.

The Text property specifies the text that appears in the Button. The Clicked event is set to an event handler named OnButtonClicked. This handler is located in the code-behind file, BasicButtonClickPage. When the Button is tapped, the OnButtonClicked method executes. The sender argument is the Button object responsible for this event. You can use this to access the Button object, or to distinguish between multiple Button objects sharing the same Clicked event.

This particular Clicked handler calls an animation function that rotates the Label degrees in milliseconds.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

I wanted it to stay 'Modal' until I call Navigation. If you do a normal push the pushed page will go onto the navigation pages stack. The navigation page will remain visible this means the top bar that comes with a navigation page remains visible. In essence a modal push replaces the full screens contents, a normal push replaces the NavigationPage's contents.

Except on WinPhone which only supports global nav. There its a full page replace no matter what. I don't care about WinPhone because my WinPhone app is now 8. Your info about modal pushes sounds like my solution might be to initialize my NavigationPage to my ordinary Main page, and then immediately do a PushModal for my first intro screen when that's appropriate.

When the intro screen flow is complete, I can PopModal and the user is then in the right state for the main experience. Am I piecing this together right? As for 8. We unfortunately had no time to forward port after MS made their release. Thanks, Jason.

This is a pretty massive problem, and I haven't found a proper solution using xamarin forms. I was using the method Andrew outlined, but this does not work properly on android, where a modal the log in page can be removed with the hardware back button. Is there currently any way to present a page modally or notwhich the user cannot navigate back from? Or is there at least something in the works?

Its a bit of an issue when displaying a log in screen which most apps need is such a problem.In my application I have many buttons that when clicked will navigate to other pages. There should be one click only per button, however, I can click these buttons more than once, in rapid succession - like a double click, for example - in the short interval before the next page is shown, and the result is that there are multiple instances of the next page created, one per button click.
