toolStripTextBox中的Keypress事件 [英] Keypress Event in toolStripTextBox

问题描述

我有这段代码：

I have this code:

private void toolStripTextBox7_KeyPress(object sender, KeyPressEventArgs e)
        {
            if (toolStripTextBox7.Text != "one" && toolStripTextBox7.Text != "two")
            {
                pictureBox21.BringToFront();
            }
            else
            {
                pictureBox20.BringToFront();
            }
        }

当用户插入一个或两个时我希望它改变图片，但这不是做到这一点。在这种情况下，我必须写入一个或两个，然后再单击该框中的一次以刷新它，然后它可以工作。如何解决这个问题？

I want it to change the picture that moment, when user inserts "one" or "two", but this does not do it. In this case i have to write in "one" or "two" and click one more time in that box to refresh it, then it works. How to fix this?

推荐答案

这不是问题 - 它与事情发生的顺序有关：KeyPress发生之前 文本按设计更改，因此如果您不想要非数字值，则可以删除按键。



尝试将代码移动到TextChanged事件中，这会在文本更改后发生。

This isn''t a problem - it has to do with the order in which things happen: KeyPress occurs before the text is changed by design, so you can remove key presses if you don''t want non-numeric values for example.

Try moving your code into the TextChanged event instead, which occurs after the text is changed.
