刷新winform上的滚动条 [英] Refresh scroll bars on winform

问题描述

我在 VB.Net 中有一个主表单，我在其中添加了一个子表单.子表单的 TopLevel 属性为 false.我激活了主窗体上的滚动条(AutoScroll = true).

I have a main-form in VB.Net in which I add a sub-form. The sub-form has the property TopLevel to false. I activated the scroll bars on the main-form (AutoScroll = true).

现在，在运行时，当我在主窗体内移动子窗体时，滚动条不会立即出现.我应该稍微调整一下主窗体的大小，以便将子窗体的位置考虑在内.

Now, at run-time, when I move the sub-form inside the main-form, the scroll bars don't appear immediatly. I should resize the main-form little bit in order to take the position of the sub-form into consideration.

我在子表单中添加了以下代码以在移动时刷新主表单但它不起作用.

I added the following code in the sub-form to refresh the main one in case of move but it's not working.

Private Sub Form2_Move(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Move
    Me.Parent.Refresh()
End Sub

我也试过

Me.ParentForm.AdjustFormScrollbars(True)

但我遇到了编译错误，重载解析失败，因为无法访问AdjustFormScrollbars".

but I'm having a compilation error, Overload resolution failed because no 'AdjustFormScrollbars' is accessible.

有谁知道如何刷新"主窗体上的滚动条?

Does anyone know how to "refresh" the scroll bars on the main-form ?

谢谢.

推荐答案

得到答案:

Private Sub Form2_Move(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Move

End Sub
