在VB.net中动态添加用户控件 [英] Dynamically add a usercontrol in VB.net

问题描述

我已经制作了一个自定义的UserControl i Vb.net（Windows应用程序）。

I have made a custom UserControl i Vb.net (windows application).

如何将其动态添加到表单中？

How can I add this dynamically to a form?

推荐答案

UserControl本质上只是另一个类。它继承自Control，因此您可以使用控件执行各种操作，但除此之外，它只是一类。因此，要将用户控件动态添加到表单中，请执行以下操作：

A UserControl is essentially just another class. It inherits from Control, so you can do all kinds of things you do with controls, but otherwise it's just a class. Thus, to add the usercontrol dynamically to your form you'd do the following:

1. 创建控件的新实例。像 Dim X As New MyControl（）


2. 将控件作为子对象添加到窗体中，并将​​其添加到所需的任何容器中。就像 Me.MyGreatTabPage.Controls.Add（X）。您也可以直接将其添加到表单中，因为表单也是容器。


3. 设置控件在容器中的位置。那将设置 X.Location 和 X.Size 。

1. Create a new instance of your control. Like Dim X As New MyControl()
2. Add the control to your form as a child object to whatever container you want it. Like Me.MyGreatTabPage.Controls.Add(X). You can also add it directly to your form too, because a form is also a container.
3. Set the controls position within the container. That would be setting X.Location and X.Size.

请记住，使用 New MyControl（）创建的每个实例将是一个单独的MyControl。不要犯重复创建新控件并将它们以某种方式彼此放置的错误。创建并放置一次控件。将其分配给表单的成员变量，并在需要使用它时使用此变量。

Remember that each instance you create with New MyControl() will be a separate MyControl. Don't make the mistake of repeatedly creating new controls and placing them over each other somehow. Create and place the control once. Assign it to a member variable to your form, and when you need to work with it, use this variable.
