Gets or sets a graphics transformation that should apply to this element when layout is performed. This is a dependency property.
Assembly: PresentationFramework (in PresentationFramework.dll)
'Declaration Public Property LayoutTransform As Transform 'Usage Dim instance As FrameworkElement Dim value As Transform value = instance.LayoutTransform instance.LayoutTransform = value
In contrast to RenderTransform, will affect results of layout.
Setting a transform provides powerful capabilities of scaling and rotating. However, ignores TranslateTransform operations. This is because the layout system behavior for child elements of a FrameworkElement auto-corrects any offsets to the position of a scaled or rotated element into the layout and coordinate system of the parent element.
Example scenarios where would be useful include: rotating elements such as menu components from horizontal to vertical or vice versa, scaling elements (zooming in) on focus, providing editing behavior, etc.
Performance Note: Before using , be sure that you understand how this property can affect performance.
can lead to poor application performance if you invoke it in a scenario that does not require a full pass by the layout system. When you apply a to the Children collection of the Panel, it triggers a new pass by the layout system and forces all on-screen objects to be remeasured and rearranged. If you are updating the complete application user interface (UI), this functionality might be exactly what you need. However, if you do not need a full layout pass, use the RenderTransform property, which does not invoke the layout system, and therefore, is typically a better choice for this scenario.
Dim btn2 As New Button() btn2.Background = Brushes.LightCoral btn2.Content = "RotateTransform" btn2.LayoutTransform = New RotateTransform(45, 25, 25) Grid.SetRow(btn2, 0) Grid.SetColumn(btn2, 1) grid1.Children.Add(btn2)
