Gets or sets a value indicating whether the control has captured the mouse.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
When a control has captured the mouse, it receives mouse input whether or not the cursor is within its borders. The mouse is typically only captured during drag operations.
Only the foreground window can capture the mouse. When a background window attempts to do so, the window receives messages only for mouse events that occur when the mouse cursor is within the visible portion of the window. Also, even if the foreground window has captured the mouse, the user can still click another window, bringing it to the foreground.
When the mouse is captured, shortcut keys should not work.
The following code example demonstrates the property. To run this example paste the following code in a form containing a Label named label1 and two ListBox controls named listbox1 and listbox2. Ensure the form and controls' MouseDown event is associated with the method in this example.
'This method handles the mouse down event for all the controls on the form. When a control has 'captured the mouse, the control's name will be output on label1. Private Sub Control_MouseDown(ByVal sender As System.Object, _ ByVal e As System.Windows.Forms.MouseEventArgs) Handles MyBase.MouseDown, _ label1.MouseDown, listbox1.MouseDown, listbox2.MouseDown Dim control As Control = CType(sender, Control) If (control.Capture) Then label1.Text = control.Name & " has captured the mouse" End If End Sub
