UIElement.IsMeasureValid Property

  • Article

Gets a value indicating whether the current size returned by layout measure is valid.

Namespace: Microsoft.SPOT.Presentation
Assembly: Microsoft.SPOT.TinyCore (in microsoft.spot.tinycore.dll)

Syntax

public bool IsMeasureValid { get; }

Property Value

true if the measure pass of layout returned a valid and current value; otherwise, false.

Remarks

You can force measurement and arrangement to be invalidated by calling InvalidateMeasure on this element (or its parents). This flags the layout for recomposition at such time as the layout system determines. Alternatively, an immediate call to UpdateLayout could be made, but this should only be done if it is certain that no further invalidations are pending (a large number of unnecessarily forced updates has performance consequences).

If IsMeasureValid is false, IsArrangeValid must also be false (by the enforced logic of the layout process, arrangement cannot be valid without measurement first being valid).

Version Information

Available in the .NET Micro Framework versions 2.0, 2.5, 3.0, 4.0, and 4.1.
