一键调用2个用户控件，在Winforms中单击 [英] calling 2 user controls with one button click in winforms

问题描述

我试图一键调用2个用户控件.我可以使它与一个用户控件一起使用，但是当我尝试添加第二个用户控件时，它给了我一些问题.

我正在使用:

I am trying to call 2 user controls with one button click. I can get it to work with one user control, but when I try adding the second user control it gives me issues.

I am using:

Dim obj1 As New UserControl1
obj1.AutoSize = True
obj1.AutoScroll = True
frmMain.pnlUser.Controls.Add(obj1)

当我尝试调用第二个时，我只是在同一按钮下使用相同的编码，但是将obj1更改为obj2，将usercontol1更改为usercontol2，并告诉它什么面板. 我是新来的，所以VB编码对您有什么帮助.

When I try to call the second one I just use the same coding under the same button but change the obj1 to obj2 and the usercontol1 to usercontol2 and tell it what panel.
I am new to this so any help would be great with the VB coding.

推荐答案

您是说要通过一次单击创建两个用户控件吗? br/> 我使用您的代码创建了自己的示例，并且效果很好.我使用了两个面板，两个用户控件和一个按钮.通过代码的外观，我假定frmMain是对传递给按钮单击处理程序所在的第二个窗体的主窗体的引用，因此我也这样做.这是我的代码，如果对您不起作用，它对我来说就很好，我认为您只是忽略了一些小细节.

Are you saying that you want to create two users controls using one button click?
I create my own example using your code and it worked fine. I used two panels, two user controls, and a button. By the look of your code I assumed frmMain to be a reference to your main form passed to a second form where the button click handler was located so I did this as well. Here is my code and it worked just fine for me if it is not working for you I assume you are just overlooking some small detail.

Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
    Dim obj1 As New UserControl1
    obj1.AutoSize = True
    obj1.AutoScroll = True
    frmMain.Panel1.Controls.Add(obj1)

    Dim obj2 As New UserControl2
    obj2.AutoSize = True
    obj2.AutoScroll = True
    frmMain.Panel2.Controls.Add(obj2)
End Sub

让我知道.

另外，如果您遇到任何错误，请将其发布.

Let me know.
