ToolStrip.AllowItemReorder Property

Gets or sets a value indicating whether drag-and-drop and item reordering are handled privately by the ToolStrip class.

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

public bool AllowItemReorder { get; set; }

Property Value

Type: System.Boolean
true to cause the ToolStrip class to handle drag-and-drop and item reordering automatically; otherwise, false. The default value is false.


AllowDrop and AllowItemReorder are both set to true.

Set the AllowDrop property to true and set the AllowItemReorder property to false to respond to drag-and-drop behavior you have defined in the Control.DragEnter, Control.DragLeave, and Control.DragDrop events.

Set AllowDrop to false and set AllowItemReorder to true to cause the ToolStrip class to handle drag-and-drop and item reordering automatically. Set AllowItemReorder to true for two ToolStrip objects to allow dragging of items from one ToolStrip to the other. To enable the default drag-and-drop, the ALT key must be pressed during the drag operation.

Setting both AllowDrop and AllowItemReorder to true throws an exception.

The following code example demonstrates the syntax for setting common ToolStrip properties, including the AllowItemReorder 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;
