Re: text box validataion

hi,

To validate the numeric in the TextBox use

RegularExpressionValidator control
In Properties

Specify the control which control to validate in ControlToValidate Property.

In Text Property Specify any Error Message.

Re: text box validataion

hi,

Its a server side validation control, this control can be used in VB or C# and one more thing u have to mainly specify the Validation Expression in the control property.

Numeric Validation : \d {3,5} -----> d -Numeric Checking, {} - Size
Character Validation : \D {5,10} -----> D - Character Validation, {} - Size.

Regards
Shailu.

Re: text box validataion

If the intention is only to make the textbox accept only numeric values, just very simply use the Isnumeric function.

that is

ASP.NET Syntax (Toggle Plain Text)
 
if not Isnumeric(textbox.text) then
 'do stuff like forcing retyping of content
end if
 
 
if not Isnumeric(textbox.text) then
 'do stuff like forcing retyping of content
end if

Hope this helps.

Hi,
First of all you need validation for textbox and you want user to enter only numeric values. So rather than allowing user to enter something and check it whether it is numeric or not is not good approach. I believe prevention is better than cure.

So you can Use FilterTextboxExtender that comes with AjaxToolkit. Please have a look at this demo

I hope this will solve your problem. You can use other tools also, they are very useful.

Happy Programming!!
