如何将可用的SerialPort名称添加到RibbonComboBox或RibbonGallery [英] How to add available SerialPort names to RibbonComboBox or RibbonGallery

问题描述

使用以下代码，我将可用的串行端口名称添加到RibbonGallery对象:
xaml:

With following code I add available serial port names to the RibbonGallery object:
xaml:

<ribbon:RibbonComboBox Name="cmbBoxComPortName" SelectionBoxWidth="40" Label="Port name:">
    <ribbon:RibbonGallery Name="galleryComPortName" SelectionChanged="galleryComPortName_SelectionChanged" />
</ribbon:RibbonComboBox>

C#背后的代码:

code-behind c#:

galleryComPortName.ItemsSource = SerialPortAdapter.GetAvailablePortList();

SerialPortAdapter代码:

SerialPortAdapter code:

class SerialPortAdapter
{
    public static List<string> GetAvailablePortList()
    {
        var portList = SerialPort.GetPortNames().ToList();
        portList.Sort();
        return portList;
    }
}

现在的问题是，端口名称出现在组合框中，但无法选择.

The problem is now, that the port names are present in the combobox but they are not selectable.

How can I select them and treat the event to set my port name?

推荐答案

我对Ribbon:RibbonComboBox控制器有相同的问题.您的专案是.Net 3.5吗?那可能是造成我的问题.

我的解决方法是使用原始的ComboBox控制器而不是Ribbon:RibbonComboBox.

I had the same problem with Ribbon:RibbonComboBox controller. Is your project .Net 3.5? That might be causing my problems.

My workaround was to use the original ComboBox controller instead of Ribbon:RibbonComboBox.

抱歉，这不是解决方案.在前面的答案之后，不知道添加更多代码的方法.

现在，我尝试执行以下操作，但不幸的是得到了相同的结果.

SerialPortAdapter中的代码:

Sorry this, isn''t a solution. Don''t know a way to add more code after the previous answers.

Now I tried following, but unfortunatelly with the the same result.

Code in SerialPortAdapter:

public static ObservableCollection<RibbonGalleryItem> GetAvailablePortList()
{
    var portList = SerialPort.GetPortNames().ToList();
    portList.Sort();

    var portObsCol = new ObservableCollection<RibbonGalleryItem>();
    foreach (var rgi in portList.Select(port => new RibbonGalleryItem() { Content = port, Name = port }))
    {
        portObsCol.Add(rgi);
    }

    return portObsCol;
}

以这种方式发现了，这是可行的.

xaml:

Found out this way, which is working.

xaml:

<ribbon:RibbonComboBox Name="cmbBoxComPortNameRibbon" SelectionBoxWidth="40" Label="Port name:">
    <ribbon:RibbonGallery Name="galleryComPortName" SelectionChanged="GalleryComPortNameSelectionChanged" SelectedValuePath="Content">
        <ribbon:RibbonGalleryCategory Name="galleryCategoryComPortName"/>
    </ribbon:RibbonGallery>
</ribbon:RibbonComboBox>

C#背后的代码:

code-behind C#:

galleryCategoryComPortName.ItemsSource = SerialPortAdapter.GetAvailablePortList();

SerialPortAdapter代码:

SerialPortAdapter code:

public static ObservableCollection<RibbonGalleryItem> GetAvailablePortList()
{
    var portList = SerialPort.GetPortNames().ToList();
    portList.Sort();

    var portObsCol = new ObservableCollection<RibbonGalleryItem>();
    foreach (var rgi in portList.Select(port => new RibbonGalleryItem() { Content = port, Name = port }))
    {
        portObsCol.Add(rgi);
    }

    return portObsCol;
}
