我怎样才能让一个RichTextBox滚动到最后当我添加一个新行？ [英] How can I make a RichTextBox scroll to the end when I add a new line?

问题描述

我有几个只读的RichTextBox的是用于登录输出。因为他们是只读他们似乎并不文本时更新自动滚动。我的可以的使用TextChanged事件，迫使滚动结束，但有不只是使滚动发生像正常？

I have several read only RichTextBox's that are used for logging output. Since they're read only they don't seem to automatically scroll when the text is updated. I can use the TextChanged event to force a scroll to end, but is there not simply a way to set a property or something in the XAML so that scrolling happens like normal?

请检查并让我知道，如果是的任何使用。

我试图重现你的问题，并用以下解决方案

I tried to reproduce your problem and came up with the following solution

    <Window x:Class="CheckRichTextBox.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="170" Width="300">
    <StackPanel>
        <RichTextBox Height="100" Name="richTextBox1" IsReadOnly="True" VerticalScrollBarVisibility="Visible"/>
        <Button Name="btnAdd" Content="Click me to add text" VerticalAlignment="Bottom" Click="BtnAddClick" />
    </StackPanel>
</Window>

对于同一背后的代码如下：

The code behind for the same is as below:

using System.Windows;

namespace CheckRichTextBox
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        private void BtnAddClick(object sender, RoutedEventArgs e)
        {
            richTextBox1.AppendText("You had Clicked the button for adding text\n");
            richTextBox1.ScrollToEnd();
        }
    }
}

这解决了自动滚屏的问题，请检查一下，让我知道，如果它是任何帮助。
