UIElement.InvalidateArrange Method

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Invalidates the arrange state (layout) for a UIElement. After the invalidation, the UIElement will have its layout updated, which will occur asynchronously.

Namespace:  System.Windows
Assembly:  System.Windows (in System.Windows.dll)

Syntax

'Declaration
Public Sub InvalidateArrange

public void InvalidateArrange()

Remarks

Frequent calls to InvalidateArrange or in particular to UpdateLayout have significant performance consequences. Therefore, avoid calling this method unless you absolutely require precise layout state for subsequent calls to other APIs in your code.

This method is typically only used within layout method override implementations.
