My textbox is bound to Typed Dataset, with a Numeric Field, I want the user
should not type anything in textbox except Numeric, how can I ?
The data type is : Sql Server Decimal(5,2)

Currently, VB.Net automatically raise error on lost focus of textbox, but I
don't want user to type anything else except Numeric, any property to be set
in Textbox?

Best Regards,

Luqman,

Isnumeric(textbox.text) test on numeric,

Be aware that it takes every item that can be numeric in the
culture/language setting of a client.

For version 2005 is instead of the textbox for this the masked textbox,
however

http://msdn2.microsoft.com/en-us/library/system.windows.forms.maskedtextbox(VS.80).aspx

I hope this helps,

Cor
