在VB中通过鼠标拖动来移动控件

Question

In the final answer in this post , Paweł Wojda posts a general way to move controls with a mouse. However, I'm working in VB and have been unable to translate his approach because there are no equivalents to control.location and control.update. How can this same functionality be ported to VB.

Answer 1

The question you linked is using a Windows Forms project, however based on your most used tags I guess you're using WPF.

The equivalent to WinForms's Control.Location property is Control.Margin in WPF (top and left, specifically).

The, somewhat, equivalent to Control.Update is Control.InvalidateVisual . Although, in this case there is no need to call either, so you can just ignore it.

Answer 2

dim down as new boolean On mouse down event:

Down = true

On mouse up event:

Down =false

On mouse move event:

If down = true Then
      Me.location = cursor.position
 End if
