I'm looking to accept digits and the decimal point for forms, using WPF application.
I am new to WPF
I want a textbox that takes only numeric values, in the format
12.3456
that is, 2 places before decimal point and 4 places after it.

better use specialized controls, like [DoubleUpDown](https://wpftoolkit.codeplex.com/wikipage?title=DoubleUpDown&referringTitle=Home) from wpf toolkit – ASh Oct 25 '16 at 13:08

how to use Regex for getting format of this particular type 12.3456 @croxy – Mayur95 Oct 25 '16 at 13:24

@Mayur95 I'm not a regex pro, but this should do the trick `^[\d]{2}([.][\d]{4})$` – croxy Oct 25 '16 at 13:33

no it's not working showing error for d saying unrecognized escape sequence @croxy – Mayur95 Oct 25 '16 at 13:44

Pass the regex string like this: `new Regex(@"^[\d]{2}([.][\d]{4})$");` – croxy Oct 25 '16 at 13:46

Its not getting displayed in the above format, also it is taking strings as well. @croxy – Mayur95 Oct 25 '16 at 13:49

Too bad TextBox has no Property to set the DataType of the field and the amount of Decimal Places it can hold, had to make a UserControl that does exactly what you want.
Offtopic aside, use Regex, I usually use this website to build them.
