如何引用动态创建的控件 [英] how to refer a dynamically created control

问题描述

我动态创建了一组单选按钮.代码如下:

I have dynamically created a set of radiobuttons.The code is as below:

Dim y As Integer = 10
       Dim sName As String = "test"


       For x As Integer = 1 To y

           myRB = New RadioButton()

           myRB.Location = New Point(10, y)

           myRB.Text = "Candy " & x
           myRB.Name = x

           Panel1.Controls.Add(myRB)
           y += 20
       Next

我想记录用户选择的内容，但是我应该如何引用这些控件?

请帮助

推荐答案

然后在您在RadioButtons列表或数组中创建它们(推荐)时使用它们，也可以通过Panel1.Controls数组找到它们并进行迭代:

Either store then when you create them in a list or array of RadioButtons (recommended) or you can find them via the Panel1.Controls array and iterate through:

For Each c As Control In panel1.Controls
    Dim rb As RadioButton = TryCast(c, RadioButton)
    If rb IsNot Nothing Then
        If rb.Checked Then
            ' Handle checked button
            Exit For
        End If
    End If
Next

如果选择第二个选项，则将一个独特的值添加到Tag属性中，否则您将不得不检查Text以确定它是哪个.

If you chose the second option, I would put a distinctive value into the Tag property, or you will have to check the Text to tell which one it is.
