AutoClose Property

ToolStripDropDown::AutoClose Property

Gets or sets a value indicating whether the ToolStripDropDown control should automatically close when it has lost activation.

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

public:
property bool AutoClose {
	bool get ();
	void set (bool value);
}

Property Value

Type: System::Boolean
true if the ToolStripDropDown control automatically closes; otherwise, false. The default is true.

If you want a ToolStripDropDown that always stays open, set AutoClose to false.

NoteNote

Consider handling the Closing event instead of setting the AutoClose property. Inspect the CloseReason field in your Closing handler to specify custom closing logic.

The following code example demonstrates how to toggle the value of the AutoClose property in response to a check box selection.
