Examples

The following code example demonstrates the syntax for setting common ToolStrip properties, including the AutoSize 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[] {
toolStripButton1});
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;

' This is an example of some common ToolStrip property settings.
' 
toolStrip1.AllowDrop = False
toolStrip1.AllowItemReorder = True
toolStrip1.AllowMerge = False
toolStrip1.Anchor = CType(System.Windows.Forms.AnchorStyles.Top Or System.Windows.Forms.AnchorStyles.Left Or System.Windows.Forms.AnchorStyles.Right, System.Windows.Forms.AnchorStyles)
toolStrip1.AutoSize = False
toolStrip1.CanOverflow = False
toolStrip1.Cursor = Cursors.Cross
toolStrip1.Dock = System.Windows.Forms.DockStyle.None
toolStrip1.DefaultDropDownDirection = ToolStripDropDownDirection.BelowRight
toolStrip1.GripMargin = New System.Windows.Forms.Padding(3)
toolStrip1.ImageScalingSize = New System.Drawing.Size(20, 20)
toolStrip1.Items.AddRange(New System.Windows.Forms.ToolStripItem() {toolStripButton1})
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

Remarks

If you set AutoSize to false and the ToolStrip is embedded in a ToolStripContainer panel, the bounds of the ToolStrip are not translated when you move the ToolStrip to a different panel of the ToolStripContainer. To translate the bounds properly, synchronize the LayoutStyleChanged event, check the value of the Orientation property, and resize the ToolStrip.

The Image, ImageAlign, ImageIndex, ImageKey, and ImageScaling properties pertain to various aspects of image handling. Use images in ToolStrip controls by setting these properties directly or by setting the run-time-only ImageList property.

Image scaling is determined by the interaction of properties in both ToolStrip and ToolStripItem, as follows:

• ImageScalingSize is the scale of the final image as determined by the combination of the image's ImageScaling setting and the container's AutoSize setting.

  • If AutoSize is true (the default) and ToolStripItemImageScaling is SizeToFit, no image scaling occurs, and the ToolStrip size is that of the largest item, or a prescribed minimum size.

  • If AutoSize is false and ToolStripItemImageScaling is None, neither image nor ToolStrip scaling occurs.
