为什么我的文本框 TextChanged 事件在我输入“only"后被触发?我的文本框中的一个字符? [英] Why my textbox TextChanged event gets fired after I enter "only" one character in my text box?

问题描述

private void NameVal_TextChanged(object sender, EventArgs e)
    {
        String text = NameVal.Text;

    }

只要我输入我名字的第一个字母，这个程序就会被执行.如何让程序等到我完成输入字段的整个字符串(例如 Name ex: James).

As soon as I enter the first letter of my Name this program gets executed . How do I make the program wait until I finish entering the whole string for the field (such as Name ex: James) is entered.

推荐答案

如果您想确定用户何时完成输入，您可以捕获 leave 事件 - 当焦点在该文本框上丢失时触发 -即用户在文本框外点击:

If you want to determine when the user has finished typing, you can catch the leave event instead - this is fired when the focus is lost on that text box - ie the user clicks outside of the textbox:

private void NameVal_Leave(object sender, EventArgs e)
{
    //Do your stuff
    String text = NameVal.Text;
}
