仅用于用户输入的 TextBox 事件

TextBox event for only user input(仅用于用户输入的 TextBox 事件)

问题描述

我有一个文本框控件，它有时以编程方式更新，也可以由用户更新.我如何区分这两个事件?我想要一个Dirty"标志设置为真"；当用户更改文本时.

I have a Textbox control which sometimes updated programmatically and also can be update by the user. How can I distinct between those two event? I'd like to have a "Dirty" flag set to "True" when the user changes the text.

推荐答案

可以使用文本框的Key Down事件.

You can use the Key Down event of the text box.

  private void textBox1_KeyDown(object sender, KeyEventArgs e)
  {
      // Insert the code you want to run when the text changes here!
  }
