Property Value
A bitwise combination of the AnchorStyles values. The default is Top and Left.Use the Anchor property to define how a control is automatically resized as its parent control is resized. Anchoring a control to its parent control ensures that the anchored edges remain in the same position relative to the edges of the parent control when the parent control is resized.
You can anchor a control to one or more edges of its container. For example, if you have a Form with a Button whose Anchor property value is set to Top and Bottom, the Button is stretched to maintain the anchored distance to the top and bottom edges of the Form as the Height of the Form is increased.

|---|
| The Anchor and Dock properties are mutually exclusive. Only one can be set at a time, and the last one set takes precedence. |
The following code example adds a Button to a form and sets some of its common properties. The example anchors the button to the bottom-right corner of the form so it keeps its relative position as the form is resized. Next it sets the BackgroundImage and resizes the button to the same size as the Image. The example then sets the TabStop to true and sets the TabIndex property. Lastly, it adds an event handler to handle the Click event of the button. This example requires that you have an ImageList named imageList1.
