exclude 0 as first character

[Reine]

I have a five digit postal code and want to exclude zero as first character and only allow numeric values.

Html.Kendo().MaskedTextBoxFor(a => a.Postnummer)
                    .Rules(rules => { rules.Add('0', "/[1-9]/"); })
                    .Mask("00000"))

 

not working, cant type in 0 at all.

Hello Reine,

To achieve your goal you need to use a custom mask rule. Learn more about these here:

http://docs.telerik.com/kendo-ui/aspnet-mvc/helpers/maskedtextbox/overview#define-custom-mask-rules

The code for not allowing zero as the first digit will look similar to the following:

Html.Kendo().MaskedTextBoxFor(a => a.Postnummer)
                    .Rules(rules => { rules.Add('~', "/[1-9]/"); })
                    .Mask("~0000"))

This allows only digits 1-9 for the first character and 0-9 for the rest. The 0 is a predefined mask rule. You can see a list at the following URL:

I hope this helps.
