textbox control

[kidzero]

Hello,

i have text box control in from(windows form). Now i want that this textbox
could accept only numeric values. In MFC editbox had special option (number)
and everything was well, but in C# i can't find anything like that.

Programming language C#

Thank you.

Hi,

This issue has been discussed before in this NG, take a look at the history
in google:

http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&oe=UTF-8&q=TextBox+numeric+validation

This is a method that I have used:

Re: textbox control

If you're interested, check out the article at:

http://www.codeproject.com/cs/miscctrl/ValidatingTextBoxControls.asp

This article includes the C# source code for 9 different text box controls
including: Alphanumeric TextBox, Currency TextBox, Date TextBox, DateTime
TextBox, Integer TextBox, Masked TextBox, Multi-Masked TextBox, Numeric
TestBox, and Time TextBox.

It's a well-written article and nice example of C# code.

- FWIW, Jeff

Re: textbox control

take a look at the following article. basically you have two choices:

1. let the user write whatever he/she wants, then show an error message and
focus the textbox using validating and validated events

2. you can detect the characters entered into the textbox using the keydown
or some other event and simply ignore that character (in your case which are
not numeric)
