不触发vb.net中的文本框更改事件 [英] Not fire the textbox change event in vb.net

问题描述

我在winform应用程序(VB.Net2003)中有多个文本框，并进行了一些计算，例如1 * 10 = 10.当我在文本框中输入数字值的速度非常快时(即12,16任意)，但是我只得到值1的第一位(正确的输出是20，但我只有10).值2不能计算因此，如何纠正此问题.

要使用Textchanged事件....

预先感谢.

i have multiple textbox in winform application(VB.Net2003) with some calculation like 1 * 10 =10. when i enter the numberic values in text box as very fast (ie 12,16 any), But i getting only first digit of value 1 (correct output is 20 but i''m getting only 10). The value 2 is not calculate So, how to rectify this problem.

Textchanged event to be used....

Thanks in advance.

推荐答案

原因是在控件中的每次更改后都会触发Textchanged事件.

干杯

Hi,
The reason is that Textchanged event will be fired after every change in the control.

Cheers

代替TextChange事件，请尝试LostFocus事件.因为此事件将在光标或控件离开文本框后触发，所以您不会丢失任何数字.

希望它能起作用.

Hi,
Instead of TextChange Event, Try LostFocus Event. because this event will fire after the cursor or control came out of the textbox, so that you may not lose any digits.
