ToolStripDropDown.AutoClose Property

Note: This property is new in the .NET Framework version 2.0.

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)

'Declaration
Public Property AutoClose As Boolean
'Usage
Dim instance As ToolStripDropDown
Dim value As Boolean

value = instance.AutoClose

instance.AutoClose = value
/** @property */
public boolean get_AutoClose ()

/** @property */
public void set_AutoClose (boolean value)

public function get AutoClose () : boolean

public function set AutoClose (value : boolean)

Property Value

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.

' This method toggles the value of the ToolStripDropDown 
' control's AutoClose property.
Private Sub autoCloseCheckBox_CheckedChanged(sender As Object, e As EventArgs) Handles autoCloseCheckBox.CheckedChanged
   Me.contextMenuStrip1.AutoClose ^= True
 End Sub
