Panel.SetZIndex Method

.NET Framework 4.5

[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]

Sets the value of the ZIndex attached property for a given element.

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

Syntax

C++

public static void SetZIndex(
	UIElement element,
	int value
)

Parameters

element: Type: System.Windows.UIElement
The element on which to apply the property value.

value: Type: System.Int32
The order on the z-plane in which this element appears.

Exceptions

Exception	Condition
ArgumentNullException	The element is null.

Remarks

The greater the value of a given element, the more likely the element is to appear in the foreground. Likewise, if an element has a relatively low value, the element will likely appear in the background. For example, an element that has a value of 5 will appear above an element that has a value of 4, which in turn will appear above an element that has a value of 3, and so on. Negative values are allowed, and they continue this precedence pattern.

Members of a Children collection that have equal ZIndex values are rendered in the order in which they appear in the visual tree. You can determine the index position of a child by iterating the members of the Children collection.

Examples

The following example demonstrates in code how to set the value of the ZIndex property (by using the SetZIndex method).

C++


Canvas.SetTop(myRectangle2, 150);
Canvas.SetLeft(myRectangle2, 150);
Canvas.SetZIndex(myRectangle2, 1);
myRectangle2.Fill = Brushes.Yellow;
myRectangle2.Width = 100;
myRectangle2.Height = 100;
