範例

下列程式碼範例示範設定通用 ToolStrip 屬性的語法，包括 AllowDrop 屬性。

// 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

備註

將 AllowDrop 屬性設定為 true ，並將 屬性設定 AllowItemReorder 為 false ，以回應您在 、 Control.DragLeave 和 Control.DragDrop 事件中 Control.DragEnter 定義的拖放行為。

設定為 false ，並將 設定 trueAllowDropAllowItemReorder 為 ，讓 ToolStrip 類別自動處理拖放和專案重新排序。 true針對兩 ToolStrip 個 物件設定 AllowItemReorder 為 ，以允許將專案從一個拖曳到另一個 ToolStrip 物件。 若要啟用預設拖放功能，必須在拖曳作業期間按下 ALT 鍵。

AllowDrop將 和 AllowItemReorder 設定為 true 會擲回例外狀況。
