Question

我的申请需要一系列问题，范围从1到1000 问题由用户设置，我需要groupbox来包含 2个单选按钮如下所示。该代码确实创建了包含2个单选按钮的多个组框。

此代码处于一个循环中，该循环由需要多少问题确定。

问题是当在任何一个组框中单击一个单选按钮时，它删除了之前点击过groupbox的点击。

如何解决此问题？

Answer 1

我认为这是因为pnlQ11是另一个UserControl（我猜您正在使用Windows窗体），并且根据MSDN，控件只能分配给一个Control.ControlCollection （http://msdn.microsoft.com/en-us/library/system.windows.forms.control.controlcollection.add%28v=vs.100%29.aspx）。

因此，您的RadioButton已从GroupBox移除，并添加到pnlQ11，这是所有其他RadioButton所属的控件。然后，解决方案是避免将RadioButton添加到其他控件并仅将其保留在GroupBox

中

在任何组框中单击单选按钮，它将删除之前单击过组框的单击
