Visual Get Size Request(Double, Double) Element.
Get Size Request(Double, Double)
This API is now obsolete.
Returns the SizeRequest of the element. Calling this method begins the measure pass of a layout cycle.
[System.Obsolete("OnSizeRequest is obsolete as of version 2.2.0. Please use OnMeasure instead.")] public virtual Xamarin.Forms.SizeRequest GetSizeRequest (double widthConstraint, double heightConstraint);
abstract member GetSizeRequest : double * double -> Xamarin.Forms.SizeRequest override this.GetSizeRequest : double * double -> Xamarin.Forms.SizeRequest
The available width that a parent element can allocated to a child. Value will be between 0 and double.PositiveInfinity.
The available height that a parent element can allocated to a child. Value will be between 0 and double.PositiveInfinity.
Calling GetSizeRequest causes a measure pass to occur for the subtree of elements it is called on. It is ideal to only call GetSizeRequest when needed as excessive calls can negatively impact the performance of your app. Overriding GetSizeRequest should only be done if you want to ignore Width/HeightRequest. More likely a subclass would wish to override Xamarin.Forms.VisualElement.OnSizeRequest.
