问题描述

我有一个包含以下(重要)属性的文本框:

I have a textbox with the following (important) properties:

this.license.Multiline = true;
this.license.ReadOnly = true;
this.license.ScrollBars = System.Windows.Forms.ScrollBars.Vertical;
this.license.ShortcutsEnabled = false;

看起来像这样:

如何禁止用户突出显示此文本框中的文本(我不想完全禁用该文本框)?

How can I disable the user to highlight text in this textbox (I do not want to disable the textbox completely)?

推荐答案

附加到 SelectionChanged 事件,并在事件内部设置 e.Handled = true;SelectionLength = 0; 这将阻止选择发生.这类似于防止按键发生.

Attach to the SelectionChanged event, and inside the event set e.Handled = true; and the SelectionLength = 0; and that will stop the selection from occuring. This is similar to what it takes to keep a key press from happening.
