TextBox中的约束 [英] Constraints in TextBox

问题描述

大家好，

有没有一种方法可以限制用户在TextBox控件中仅输入数字?

我可以使用TextChanged事件处理程序并删除数字以外的任何字符，但是有更简单的方法吗?

非常感谢您的帮助.

谢谢，

Hello Guys,

Is there a way to restrict users to input only numbers in TextBox control?

I can use the TextChanged Event handler and remove any character other than numbers but is there an easier way to do it?

Your help is highly appreciated.

Thanks,

推荐答案

如果您使用多个数字文本框，则可以构建自己的控件 ^ ].

If you are using multiple numeric text boxes you can build your own control[^].

我前一阵子可能有用- ^ ].

它是一个数字文本框，而不是一个 Number 文本框，因为它仍将输入视为字符串，不带小数点且不带符号.

I made one a while ago that may be of use - here[^].

It is a NumericTextBox rather than a NumberTextBox as it still treats the input as a string, no decimal point and no - sign.

尝试使用NumericUpDown代替.也许它将为您完成工作.

Try using a NumericUpDown instead. Maybe it will do the job for you.
