ToolStrip.AllowDrop Property
Assembly: System.Windows.Forms (in system.windows.forms.dll)
/** @property */ public boolean get_AllowDrop () /** @property */ public void set_AllowDrop (boolean value)
public override function get AllowDrop () : boolean public override function set AllowDrop (value : boolean)
Property Value
true to control drag-and-drop and item reordering through events that you implement; otherwise, false.| Exception type | Condition |
|---|---|
| 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 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;
