ToolStrip.Anchor Property


Gets or sets the edges of the container to which a ToolStrip is bound and determines how a ToolStrip is resized with its parent.

Namespace:   System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public override AnchorStyles Anchor { get; set; }

Property Value

Type: System.Windows.Forms.AnchorStyles

One of the AnchorStyles values.

Use the Anchor property to define how a ToolStrip 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.


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 demonstrates the syntax for setting common ToolStrip properties, including the Anchor property.

// This is an example of some common ToolStrip property settings.
toolStrip1.AllowDrop = false;
toolStrip1.AllowItemReorder = true;
toolStrip1.AllowMerge = false;
toolStrip1.Anchor = ((System.Windows.Forms.AnchorStyles)(((System.Windows.Forms.AnchorStyles.Top | System.Windows.Forms.AnchorStyles.Left)
            | System.Windows.Forms.AnchorStyles.Right)));
toolStrip1.AutoSize = false;
toolStrip1.CanOverflow = false;
toolStrip1.Cursor = System.Windows.Forms.Cursors.Cross;
toolStrip1.DefaultDropDownDirection = System.Windows.Forms.ToolStripDropDownDirection.BelowRight;
toolStrip1.Dock = System.Windows.Forms.DockStyle.None;
toolStrip1.GripMargin = new System.Windows.Forms.Padding(3);
toolStrip1.Items.AddRange(new System.Windows.Forms.ToolStripItem[] {
toolStrip1.ImageScalingSize = new System.Drawing.Size(20, 20);
toolStrip1.LayoutStyle = System.Windows.Forms.ToolStripLayoutStyle.HorizontalStackWithOverflow;
toolStrip1.Location = new System.Drawing.Point(0, 0);
toolStrip1.Margin = new System.Windows.Forms.Padding(1);
toolStrip1.Name = "toolStrip1";
toolStrip1.Padding = new System.Windows.Forms.Padding(0, 0, 2, 0);
toolStrip1.RenderMode = System.Windows.Forms.ToolStripRenderMode.System;
toolStrip1.ShowItemToolTips = false;
toolStrip1.Size = new System.Drawing.Size(109, 273);
toolStrip1.Stretch = true;
toolStrip1.TabIndex = 0;
toolStrip1.TabStop = true;
toolStrip1.Text = "toolStrip1";
toolStrip1.TextDirection = System.Windows.Forms.ToolStripTextDirection.Vertical90;
