Date de publication : novembre 2016

Obtient ou définit les bords du conteneur auquel un contrôle est lié et détermine comment un contrôle est redimensionné avec son parent.

Espace de noms:   System.Windows.Forms
Assembly:  System.Windows.Forms (dans System.Windows.Forms.dll)

public virtual AnchorStyles Anchor { get; set; }

Valeur de propriété

Type: System.Windows.Forms.AnchorStyles

Combinaison d'opérations de bits des valeurs AnchorStyles. La valeur par défaut est Top et Left.

Use the P:System.Windows.Forms.Control.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 T:System.Windows.Forms.Form with a T:System.Windows.Forms.Button whose P:System.Windows.Forms.Control.Anchor property value is set to Top and Bottom, the T:System.Windows.Forms.Button is stretched to maintain the anchored distance to the top and bottom edges of the T:System.Windows.Forms.Form as the P:System.Windows.Forms.Control.Height of the T:System.Windows.Forms.Form is increased.

System_CAPS_noteRemarque

The P:System.Windows.Forms.Control.Anchor and P:System.Windows.Forms.Control.Dock properties are mutually exclusive. Only one can be set at a time, and the last one set takes precedence.

Remarques à l’attention des héritiers :

When overriding the P:System.Windows.Forms.Control.Anchor property in a derived class, use the base class's P:System.Windows.Forms.Control.Anchor property to extend the base implementation. Otherwise, you must provide all the implementation. You are not required to override both the get and setaccessors of the P:System.Windows.Forms.Control.Anchor property; you can override only one if needed.

The following code example adds a T:System.Windows.Forms.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 P:System.Windows.Forms.Control.BackgroundImage and resizes the button to the same size as the T:System.Drawing.Image. The example then sets the P:System.Windows.Forms.Control.TabStop to true and sets the P:System.Windows.Forms.Control.TabIndex property. Lastly, it adds an event handler to handle the E:System.Windows.Forms.Control.Click event of the button. This example requires that you have an T:System.Windows.Forms.ImageList named imageList1.

// Add a button to a form and set some of its common properties.
private void AddMyButton()
{
   // Create a button and add it to the form.
   Button button1 = new Button();

   // Anchor the button to the bottom right corner of the form
   button1.Anchor = (AnchorStyles.Bottom | AnchorStyles.Right);

   // Assign a background image.
   button1.BackgroundImage = imageList1.Images[0];

   // Specify the layout style of the background image. Tile is the default.
   button1.BackgroundImageLayout = ImageLayout.Center;

   // Make the button the same size as the image.
   button1.Size = button1.BackgroundImage.Size;

   // Set the button's TabIndex and TabStop properties.
   button1.TabIndex = 1;
   button1.TabStop = true;

   // Add a delegate to handle the Click event.
   button1.Click += new System.EventHandler(this.button1_Click);

   // Add the button to the form.
   this.Controls.Add(button1);
}
