Regular Expression for variable Mask

created 10 years ago

Dear all,

I know this is a bit much asked but please help me define a regex for a phone number mask. I just don't know how to do this.

I have a texteditor which should be able to support two different phone masks, with the user being able to fill in whatever applies

042 342 10 76
12423 342 10 76

Each number consists of 4 parts, as follows:

part1: 3-5 digits, if not all 5 digits are used no placeholder should be shown once the text edit looses focus (the displayed value should be just like 1)
part 2: always 3 digits
part 3 + 4: each always 2 digits

The best i was able to achieve was using a simple editor, but that resulted in 1) looking like: __042 342 10 76 or 042__ 342 10 76 when not edited, instead of 042 342 10 76.

Thank you so much for your help!

Hi Marc,

Try the following expression:

(\d{3})|(\d{4}) \d{3} \d{2} \d{2}

C#
this.textEdit1.Properties.Mask.EditMask = "(\\d{3})|(\\d{4}) \\d{3} \\d{2} \\d{2}";  
this.textEdit1.Properties.Mask.MaskType = DevExpress.XtraEditors.Mask.MaskType.RegEx;  
this.textEdit1.Properties.Mask.ShowPlaceHolders = false;

Let me know of your results.

Dear Alisher,
Thanks so much for your fast response. That helped a lot. I had to make a small adjustment as it didn't allow me to only provide 3 digits. It appears two brackets were unneccessary. This is my result which works:
(\d{3}|\d{5}) \d{3} \d{2} \d{2}
Thank you Alisher!!
