Describes the thickness of a frame around a rectangle.
Alignment, Margins, and Padding Overview
Four Double values describe the LeftTopRightand Bottom sides of the rectangle, respectively. You can specify Thickness values in three ways. If you pass four Double values to the structure, they represent the LeftTopRight and Bottom sides, respectively, of the bounding rectangle.
You can also supply two Double values, the first value represents the Left and Right sides of the bounding rectangle and the second value represents the Top and Bottom sides of the bounding rectangle. You can also supply a single Double value, which applies a uniform value to all four sides of the bounding rectangle.
If only a single measure is specified, that measure is applied to ALL of the left,top,right,bottom values of a Thickness. If only a pair of left,top measures are specified, these measures are applied symmetrically to a Thickness : the left value is used for right; the top value is used for bottom. If left unspecified, will use the left value.
Values need not include the decimal point explicitly when specified as a string. The string "1" provided in XAML evaluates to a value of 1. Initializes a new instance of the Thickness structure that has the specified uniform length on each side.
Initializes a new instance of the Thickness structure that has specific lengths supplied as a Double applied to each side of the rectangle. Compares this Thickness structure to another Object for equality. Compares this Thickness structure to another Thickness structure for equality. Returns the string representation of the Thickness structure. Compares the value of two Thickness structures for equality.

Windows Assembly: PresentationFramework.The Margin and Padding properties control layout behavior when an element is rendered in the user interface. This article demonstrates the difference between the two properties, and how to set them. Note that Margin values are additive.
Therefore, if two adjacent elements specify a margin of 20 pixels, the distance between the elements will be 40 pixels. In addition, margin and padding are additive when both are applied, in that the distance between an element and any content will be the margin plus padding.
The Margin and Padding properties are both of type Thickness. There are three possibilities when creating a Thickness structure:. This article demonstrated the difference between the Margin and Padding properties, and how to set them.

Overview Margin and padding are related layout concepts: The Margin property represents the distance between an element and its adjacent elements, and is used to control the element's rendering position, and the rendering position of its neighbors. Margin values can be specified on layout and view classes. The Padding property represents the distance between an element and its child elements, and is used to separate the control from its own content.
Padding values can be specified on layout classes. The following diagram illustrates the two concepts: Note that Margin values are additive. There are three possibilities when creating a Thickness structure: Create a Thickness structure defined by a single uniform value. The single value is applied to the left, top, right, and bottom sides of the element. Create a Thickness structure defined by horizontal and vertical values.Margins are another vital piece of the layout system.

This series of articles explains the layout process in WPF. The series began with an understanding of the WPF layout process. The next part of this series will cover the basics of layout and positioning such as size, margin, padding and alignment of elements. Later in this series, I will cover various panels and related parent controls available in WPF.
Margin The margin is the space between an element and the parent element or other adjacent element on the same parent element. The margin adds extra space around the outside edges of an element.
The Margin property of FrameworkElement represents the margin of an element. It is a type of Thickness structure. You can either pass a single double value or four double values. When a single double value is passed to a Thickness, it applies to all four properties of the Thickness structure. If all four values of Thickness are passed, they apply to the Left, Top, Right and Bottom properties respectively.
The code snippet in Listing 1 creates two rectangles and sets the margin of the first rectangle by passing only one value 20 that sets the margin for all the four directions left, top, bottom and right to 20 each.
The margin for the second rectangle is set to 50,50,0,0. Listing 1 The output of Listing 1 looks as in Figure 1. In Figure 1, you see two rectangles. The Blue rectangle has the margin set to 20,10,10, That shows that this extra space is added between the starting point left corner of the parent control and the rectangle. View All. Mahesh Chand Updated date, Apr 13 Table of Contents.
Figure 1 Similar to the Width and Height, the units of the Margin value can be set using px, in, cm and pt. The code snippet in Listing 2 sets the Margin properties at runtime by creating a Thickness object. The next article of this series explains Alignment of WPF elements.

Getting Started With. NET 5. Getting Started with ML. NET Core.The FrameworkElement class exposes several properties that are used to precisely position child elements. This topic discusses four of the most important properties: HorizontalAlignmentMarginPaddingand VerticalAlignment. The effects of these properties are important to understand, because they provide the basis for controlling the position of elements in Windows Presentation Foundation WPF applications.
There are numerous ways to position elements using WPF. However, achieving ideal layout goes beyond simply choosing the right Panel element. Fine control of positioning requires an understanding of the HorizontalAlignmentMarginPaddingand VerticalAlignment properties.
At first glance, the Button elements in this illustration may appear to be placed randomly. However, their positions are actually precisely controlled by using a combination of margins, alignments, and padding.
The following example describes how to create the layout in the preceding illustration. A Border element encapsulates a parent StackPanelwith a Padding value of 15 device independent pixels. This accounts for the narrow LightBlue band that surrounds the child StackPanel. Child elements of the StackPanel are used to illustrate each of the various positioning properties that are detailed in this topic.
Three Button elements are used to demonstrate both the Margin and HorizontalAlignment properties. The following diagram provides a close-up view of the various positioning properties that are used in the preceding sample. Subsequent sections in this topic describe in greater detail how to use each positioning property. The HorizontalAlignment and VerticalAlignment properties describe how a child element should be positioned within a parent element's allocated layout space.
By using these properties together, you can position child elements precisely. For example, child elements of a DockPanel can specify four different horizontal alignments: LeftRightor Centeror to Stretch to fill available space. Similar values are available for vertical positioning. Explicitly-set Height and Width properties on an element take precedence over the Stretch property value. Attempting to set HeightWidthand a HorizontalAlignment value of Stretch results in the Stretch request being ignored.
The HorizontalAlignment property declares the horizontal alignment characteristics to apply to child elements. The following table shows each of the possible values of the HorizontalAlignment property. The following example shows how to apply the HorizontalAlignment property to Button elements.
Each attribute value is shown, to better illustrate the various rendering behaviors.

The preceding code yields a layout similar to the following image. The positioning effects of each HorizontalAlignment value are visible in the illustration. The VerticalAlignment property describes the vertical alignment characteristics to apply to child elements.Provides margin values for the element. The default value is a Thickness with all properties equal to 0 zero.
The margin is the space between this element and other elements that will be adjacent when layout creates the user interface UI. Shared elements might be peer elements such as other elements in the collection of a common parent controlor might also be this element's parent.Buy smm panel
Margin is set as a Thickness structure rather than as a number so that the margin can be set asymmetrically. The Thickness structure itself supports string type conversion so that you can specify an asymmetric Margin in XAML attribute syntax also. A non-zero margin applies space outside the element layout's ActualWidth and ActualHeight. Margins are additive for sibling elements in a layout; for example, two adjacent elements both with a margin of 30 set on the adjoining edge would have 60 units of space between them.
Elements that have margins set will not typically constrain the size of the specified Margin if the allotted rectangle space is not large enough for the margin plus the element content area. The element content area will be constrained instead when layout is calculated.

The only case where margins would be constrained also is if the content is already constrained all the way to zero. The attribute usage will also accept abbreviated values that apply in the order provided, symmetrically and logically. You can also specify other units by appending the unit type strings cminor pt to any measure. Number values provided as XAML attributes need not specify decimal points 0 is acceptable, does not have to be provided as 0. Skip to main content.

Is this page helpful? Yes No. Any additional feedback? Skip Submit.I finally decided to spend some time to learn WPF. One of the thing I learned today is Margin property. Every control that derives from FrameworkElement class has this property. However, I want to share with you how I memorized the sequence of margin.
It goes like this: Left, Top, Right, Bottom. The easiest way for me to remember is to start from Left and then go clock wise: Top, Right, Bottom. The second reason is that people who read my blog comment and correct any mistakes I make and that helps me to learn too.
I have a question for WPF gurus. The XAML you create can be quite different from the actual object structure the compiler builds for you. Rune has it right. Some properties of WPF objects have implicit converters attached to them based on type.
This allows the input string to take several different forms without having to specify a converter in XAML for each use.
The converter at work here is a ThicknessConverter which parses the input string and attempts to map the values given in the string to one of the Thickness object constructor overloads.
Thanks a lot for you help. It has internal method FromString that include the code bellow:. Actually the Windows standards predate css, and are more consistent with mathematics. The css folks blew it. Typographically, however, I think imho the most important margin is the top one — major movement being down the page, then the left for insetting, the others just give the area bounds … Top, Left, Bottom, Right.
I think this is more closer how you work with math rectangles, lines, polygons, shapes etc …. Just came across this page while looking for an explanation of WPF margins — love the little diagram, it was exactly what I needed to see in order to quickly understand.
