在sum文本框中添加两个文本框 [英] Adding two text box to sum text box

问题描述

您好，



有人可以帮我添加两个文本框而无需点击按钮。

例如：

Hello,

Can someone help me adding two text box without clicking a button.
example:

textbox1 = (1)
textbox2 =(50)
textboxsum = (51) <--- automated sum from textbox1 and textbox2

i已经在textbox1和textbox2上有值，我想在textboxsum上自动计算文本框的两个值。



textbox1和text2值来自我的数据库。







提前谢谢



我尝试了什么：



注意：

textchange事件有效但我需要手动输入文本框上的值以获得总和。

i have already values on textbox1 and textbox2, I want the two values of textbox automatically computed on textboxsum.

textbox1 and text2 values came from my database.



thanks in advance

What I have tried:

Note:
textchange event works but i need to manually input the values on text box in order to get the sum.

推荐答案

I would implement the TextChange-Event on the both of the textbox1 and textbox2 like this:

Try
  textboxsum.Text = Convert.toInt32(textbox1.Text) + Convert.toInt32(textbox2.Text)
Catch ...
