问题描述
我找不到那个功能.基本上我有一个多行文本框,当我执行搜索时,我会突出显示结果.但如果结果不在视图中,我将不得不手动向下滚动,直到找到突出显示的结果,这超出了查找"功能的目的.
I'm unable to find that function. Basically I have a multiline text box and when I perform a search, I highlight the result. But if the result is not within view, I would have to manually scroll down until I find the highlighted result, which beats the purpose of the "Find" functionality.
我不想使用 RichTextBox,因为我遇到了一些性能问题.
I don't want to use RichTextBox because I've encountered some performance issues with it.
推荐答案你可以使用 GetLineIndexFromCharacterIndex 结合 ScrollToLine:
You could use GetLineIndexFromCharacterIndex in combination with ScrollToLine:
var selectionStart = x; var selectionLength = y; textBox.Select(selectionStart, selectionLength); textBox.ScrollToLine(textBox.GetLineIndexFromCharacterIndex(textBox.SelectionStart));更多推荐
