wpf - 组合框可见列绑定

Question

我正在编写一个创建代码的工具（例如：代码生成器）。但是，有以下方法删除Combobox 中的 Visible Column 绑定。(WPF) 方法：

 public static string ConvertControlToString<T>(T orig)
    {
        StringBuilder outstr = new StringBuilder();
        //this code need for right XML fomating 
        XmlWriterSettings settings = new XmlWriterSettings();
        settings.Indent = true;
        settings.OmitXmlDeclaration = true;
        settings.ConformanceLevel = ConformanceLevel.Fragment;
        settings.NamespaceHandling = NamespaceHandling.OmitDuplicates;
        XamlDesignerSerializationManager dsm = new XamlDesignerSerializationManager(XmlWriter.Create(outstr, settings));
        //this string need for turning on expression saving mode 
        dsm.XamlWriterMode = XamlWriterMode.Expression;
        XamlWriter.Save(orig, dsm);
        return outstr.ToString();
    }

在这种方法中，我得出以下表达式。

panel.ContentXamlString = EditorHelper.ConvertControlToString(c.Content);

谢谢你。
