WPF：数据绑定和显示成员路径

发布于 2024-09-17 16:43:33 字数 792 浏览 8 评论 0原文

我创建了一个 RibbonGallery/ComboBox 来显示已安装字体的列表。

alt text

但有时输入后说“V”，这就是我得到的

alt text

查看菜单中的文本。

[Font Family: Name=...

为什么会发生这种情况。

代码

// xaml
<ribbon:RibbonComboBox Label="Gallery">
    <ribbon:RibbonGallery SelectedValue="ABC" SelectedValuePath="Content" MaxColumnCount="1">
        <ribbon:RibbonGalleryCategory x:Name="fontsMenu" />
    </ribbon:RibbonGallery>
</ribbon:RibbonComboBox>

// code behind
InstalledFontCollection col = new InstalledFontCollection();
fontsMenu.ItemsSource = col.Families;
fontsMenu.DisplayMemberPath = "Name";

原文

alt text

look at the text in the menu.

[Font Family: Name=...

<ribbon:RibbonComboBox Label="Gallery">
    <ribbon:RibbonGallery SelectedValue="ABC" SelectedValuePath="Content" MaxColumnCount="1">

这就是 FontFamily.ToString() 的实现方式，这正是我们所显示的：

  public override string ToString()
   {
      return string.Format(CultureInfo.CurrentCulture, "[{0}: Name={1}]", new object[] {  base.GetType().Name, this.Name });
    }

您肯定需要将一些 DisplayMemberPath 设置为“Name”，并且您已经在 RibbonGalleryCategory 上设置了一个，但现在我很好奇 - 不应该在 RibbonGallery 甚至 RibbonComboBox 上设置它？坦率地说，我还没有使用过 wpf 功能区控件 - 我所能建议的只是假设。

希望这会有所帮助:)

That's how FontFamily.ToString() implemented and thats exactly what we have displayed:

  public override string ToString()
   {
      return string.Format(CultureInfo.CurrentCulture, "[{0}: Name={1}]", new object[] {  base.GetType().Name, this.Name });
    }

You definitely need to set some DisplayMemberPath to "Name" and you already have one on RibbonGalleryCategory but now i'm curious - shouldnt it be set on RibbonGallery or even RibbonComboBox? Frankly speaking i haven't used wpf ribbon controls yet - all i can suggest is just assumption.

Hope this'll help :)
