从 WPF 中的资源文件绑定占位符 [英] Binding placeholder from resource file in WPF

问题描述

在我的资源文件中

LOCKER NO. {0} IS OPEN

我需要将资源文件绑定到一个文本框，并希望在前景为红色的palce holder中动态设置值.

I need to bind the resource file to a text box and want to dynamically set value in palce holder with foreground as red.

下面是我的代码

   <TextBlock x:Name="Title" Margin="0,70,0,0"
               HorizontalAlignment="Center"
               VerticalAlignment="Top"
               FontSize="42"
               FontWeight="SemiBold"
               Foreground="#888888"
     >
        <TextBlock.Text>
            <MultiBinding  StringFormat="{x:Static prop:Resources.LockerNumberIsOpen}">
                <Binding  Path="PrefixWithNumber"/>

            </MultiBinding>
        </TextBlock.Text>
    </TextBlock>

如何将 {0} 中的值显示为红色?

how to show a value inside {0} as red?

从背后的代码我们可以做到

From code behind we can do

Title.Text = string.Format(Properties.Resources.LockerNumberIsOpen, (this.DataContext as OpenParcelViewModel).PrefixWithNumber);
            var tr = this.Find((this.DataContext as OpenParcelViewModel).PrefixWithNumber);
            tr.ApplyPropertyValue(TextElement.ForegroundProperty, "#9ebb2b");

 private TextRange Find(string w)
        {
            var si = Title.Text.IndexOf(w);
            var sp = Title.ContentStart.GetPositionAtOffset(si + 1);
            var ep = Title.ContentStart.GetPositionAtOffset(si + w.Length + 1);
            return new TextRange(sp, ep);
        }

如何在 XAML 中做到这一点

推荐答案

您需要使用 RichTextBox.这将允许您为块内的文本设置不同的颜色，但我不知道如何绑定它.或许可以使用某种方法以所需格式使用资源创建对象，然后将其绑定到该对象.

You need to use a richTextBox. that will allow you to set different colour for text within the block but I don't know how to bind it. Perhaps use a method to create an object with the resource in the format needed then bind it to that object.

在 RichtextBox 中设置单独的颜色 这个问题有详细说明.

In terms of setting seperate colours in a RichtextBox this question has it in detail.
