在后面的代码中创建单选按钮时如何获取IsChecked?

问题描述

我是Silverlight&的新手. C#，我需要以下帮助:

从XML数据中，我将根据需要创建尽可能多的RadioButton(与root.nodes一样多)，如下所示:

I''m very new to Silverlight & C# and I need help with following:

From XML data I''m creating as many RadioButtons as needed (as many as there are root.nodes) as following:

foreach (var vItem in vXDocument.Descendants("kaart"))
            {
                vItemsCount++;

                // MC1
                RadioButton vRadioButton_MC1 = new RadioButton();
                vRadioButton_MC1.Content = vItem.Element("MC1").Value;
                vRadioButton_MC1.Name = vItemsCount + "-MC1";
                vListBox.Items.Add(vRadioButton_MC1);
 
                // MC2
                RadioButton vRadioButton_MC2 = new RadioButton();
                vRadioButton_MC2.Content = vItem.Element("MC2").Value;
                vRadioButton_MC2.Name = vItemsCount + "-MC2";
                vListBox.Items.Add(vRadioButton_MC2);
            };

现在，我要检查是否已选中RadioButtons，而没有选中.每个对象都有自己的指定名称(vRadioButton_MC1.Name = vItemsCount +"-MC1").我可以向每个RadioButton询问此属性吗?
感谢您的关注.


[edit] OP的其他解决方案中的其他信息已移至此处[/edit]
在xaml中添加了一个用户控件，这使得在选中或不选中单选按钮时都可以轻松设置变量.该变量已发送至我的代码以供使用.

Now I want to check with RadioButtons are checked and with aren''t. Every object has his own specified name (vRadioButton_MC1.Name = vItemsCount + "-MC1"). Can I ask this property for each RadioButtons?
Thanks for paying attention.


[edit]Additional information by OP in a non-solution moved here [/edit]
made an user control in xaml, wich made it easy to set a variable when a radiobutton is checked or not. That variable i''ve send to my code behind to work with.

推荐答案

private void OnChecked(object sender, RoutedEventArgs e)
{
    var control = (RadioButton)sender;
}

要使用此功能，您需要将事件添加到控件中:

To use this you need to add the event to the control:

vRadioButton_MC1.Checked += OnChecked;

更好的方法是使用MVVM模式，但这将更加复杂，因为您必须在代码中创建ICommand 绑定.将使用CommandParameter 确定激活了哪个RadioButton.

The better way to do this is to use the MVVM pattern, but that will be much more complex since you have to create a ICommand binding in code. The CommandParameter would be u8sed to determine which RadioButton was activated.

vRadioButton.IsChecked

请参见 http中的IsChecked属性. ://msdn.microsoft.com/zh-cn/library/system.windows.controls.primitives.togglebutton.ischecked%28v=VS.95%29.aspx [ ^ ]
