To show a pop-up page you can use:

When you provide a view to be opened in a pop-up, Zebble will wrap your view in an instance of Popup class which is a page with some default style to make it look like a pop-up on top of an existing page.

NOTE: Many of the existing Zebble features such as Alert, ItemPicker, etc, internally use the Popup API.

Sending parameters:

You can use an anonymous object to send parameters:

wait Nav.ShowPopup<TargetPage>(new {Param1="...", Param2=...});await Nav.ShowPopup(anyView, new {Param1="...", Param2=...});

Closing a pop-up

On the target pop-up page you will normally have a button to close the pop-up. That button should call the following to close itself:

wait Nav.HidePopup();

Receiving a result back from the pop-up

There are cases where the parent host page needs to open a pop-up page, which in turn gets some input from the user, which should be then passed back to the host page. Zebble provides you with other overloads of the Nav pop-up methods to help you achieve that.

Host page:

ar result = await Nav.ShowPopup<TargetPage, SomeType>();
// Now you can use "result".Pop-up page's close button:

..
await Nav.HidePopup(someResultValue);
Notes:

• SomeType can be a simple type such as boolean or string, or it can be a complex class.
• The type of the object returned by the pop-up must match the one expected by the host parent page.
