目前我有两个xaml文件C# 如何动态生成必须放置在动态生成的GroupBox中的切换按钮 我是C++开发人员，最近搬到C。我正在开发WPF应用程序，它处理GroupBox的动态生成。各个groupbox中存在的RadioButton、togglebutton等UI组件必须动态生成,c#,.net,wpf,mvvm,toggle,C#,.net,Wpf,Mvvm,Toggle,目前我有两个xaml文件CodecView.xaml和CodecWidgetView.xaml，这两个xaml文件都有一个单独的viewmodel类。这个充满活力的一代人很有趣，但对我来说肯定是个棘手的问题。让我向您展示动态生成一组GroupBox的代码 CodecView.xaml: <UserControl.Resources> <DataTemplate x:Key="CWDataTemplate"> <StackPanel>

}
}
codewidgetview.xamlGrid.Row=216位、20位、24位和32位
一旦发生这种情况，此按钮上必须只有一个单击事件，它设置togglestate并执行一些语句
这就是我在C++中所做的：
//In Constructor
for(int jj = 0; jj < 4; jj++)
{
m_codecBitLengthButton[jj] = new ToggleButton(bitLengthes[jj]); //Here bitlength consists of 16Bit, 20Bit, 24Bit and 32Bit
m_codecBitLengthButton[jj]->setRadioGroupId(55); // make a custom group ID
addAndMakeVisible(m_codecBitLengthButton[jj]);
m_codecBitLengthButton[jj]->addButtonListener(this);
m_codecBitLengthButton[jj]->setToggleState(false, false);
}
// check which button should be pressed
cmd = (0x9400 | (m_slot & 0xFF));
m_msp430->ReadInternalCommand(cmd, 1, readBuf); //This returns some value in readBuf
m_bitLength = readBuf[0];
m_codecBitLengthButton[readBuf[0]]->setToggleState(true, false); //Togglestate set to true on startup based on readBuf[0]
//Gets called when any of the toggle button is clicked
while(jj < 4)
{
if(button == m_codecBitLengthButton[jj])
{
// add code for bit length support
cmd = ((CODEC_LENGTH_CMD & 0x7F00) | (m_slot & 0xFF));
sendBuf[numBytes++] = jj; // this should represent the proper number of bits
m_bitLength = jj;
break;
}
jj++;
}
//在构造函数中
对于（intjj=0；jj<4；jj++）
{
m_codecBitLengthButton[jj]=new ToggleButton（bitLengthes[jj]）；//此处位长由16位、20位、24位和32位组成
m_codeBitLengthButton[jj]->setRadioGroupId（55）；//创建自定义组ID
addAndMakeVisible（m_codecBitLength按钮[jj]）；
m_codecBitLengthButton[jj]->addButtonListener（此）；
m_codecBitLengthButton[jj]->setToggleState（假，假）；
}
//检查应按下哪个按钮
cmd=（0x9400 |（m|U插槽和0xFF））；
m_msp430->ReadInternalCommand（cmd，1，readBuf）//这将在readBuf中返回一些值
m_bitLength=readBuf[0]；
m_codeCBitLength按钮[readBuf[0]]->setToggleState（真、假）//基于readBuf[0]启动时将Togglestate设置为true
//在单击任何切换按钮时调用
而（jj<4）
{
if（button==m_codecBitLengthButton[jj]）
{
//为位长度支持添加代码
cmd=（（编解码器长度cmd&0x7F00）；（m_插槽&0xFF））；
sendBuf[numBytes++]=jj；//这应该表示正确的位数
m_bitLength=jj；
打破
}
jj++；
}

希望这有帮助
编辑：
要定义随时检查哪个按钮，请绑定ViewModel中的ToogleButtons IsChecked属性和ToogleButton值的属性
private bool _isCheckedToogle1;
public bool IsCheckedToogle1
{
get { return _isCheckedToogle1; }
set
{
_isCheckedToogle1 = value;
OnPropertyChanged("IsCheckedToogle1");
}
}
private int _toogleButton1Value = 16;
public int ToogleButton1Value
{
get { return _toogleButton1Value; }
set
{
_toogleButton1Value = value;
OnPropertyChanged("ToogleButton1Value");
}
}
XAML：
还有你的新CommandLogik
public void DoSomethingExecute(object param)
{
ToggleValue result = param as ToggleValue;
if (result.Value == 16)
{
result.View.IsCheckedToogle1 = true;
result.View.IsCheckedToogle2 = false;
result.View.IsCheckedToogle3 = false;
result.View.IsCheckedToogle4 = false;
}
}
这些按钮上的内容是动态的吗？或者你所说的动态生成是什么意思？如果始终有4个按钮，只需将它们添加到xaml@Mark：You's back mate:）只有4个按钮，所有按钮都执行几乎相同的一组语句，只是做了一些小改动。请注意，这些按钮的内容必须动态生成。我的意思是Btn1的名称是16位，Btn2的名称是20位，依此类推。基于for循环，我只想以这样一种方式生成它们，我可以使用一个单击方法来处理切换状态等等，而不是重复4次。好吧，兄弟，你的代码总是工作得很好：）现在，我希望所有4个按钮都像单选按钮一样工作，即一次只检查一个按钮。其次，如果您检查代码：cmd=（0x9400 |（m_slot&0xFF））；m_msp430->ReadInternalCommand（cmd，1，readBuf）//这将返回readBuf m_bitLength=readBuf[0]中的某个值；m_codeCBitLength按钮[readBuf[0]]->setToggleState（真、假）
在我的示例中，您会发现`readBuf[0]在启动时将一个按钮设置为选中状态，因为此代码存在于构造函数中。我如何在您的方法中实现它？有一些可能性可以做到这一点，请给我几分钟时间，我将在
更新行异常，因为在“System.Windows.StaticResourceExtension”上提供值时引发了异常。
是的，当然。。。您必须将转换器添加到资源中。例如，虽然它现在运行，但如果（result.Value==16）处引发异常。
