示例

下面的代码示例演示如何设置常见的语法ToolStrip属性,包括AllowDrop属性。The following code example demonstrates the syntax for setting common ToolStrip properties, including the AllowDrop 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

注解

设置AllowDrop属性设置为true并设置AllowItemReorder属性设置为false响应中定义的拖放行为Control.DragEnterControl.DragLeave,和Control.DragDrop事件。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.

设置AllowDropfalse并设置AllowItemReordertrue导致ToolStrip类来处理拖放和项会自动重新排序。Set AllowDrop to false and set AllowItemReorder to true to cause the ToolStrip class to handle drag-and-drop and item reordering automatically. 设置AllowItemReordertrue两个ToolStrip对象以允许拖动的项从一台ToolStrip到其他。Set AllowItemReorder to true for two ToolStrip objects to allow dragging of items from one ToolStrip to the other. 若要启用默认拖放,必须在拖动操作过程中按 ALT 键。To enable the default drag-and-drop, the ALT key must be pressed during the drag operation.

将两者都设置AllowDropAllowItemReordertrue将引发异常。Setting both AllowDrop and AllowItemReorder to true throws an exception.
