Textbox validation for IP Address in WPF

问题:

I'm making a WPF Application using C#. I want to put validations on integers (0123456789 and ".") only.. The textbox is supposed to contain an IP address... So need to ensure that user key in their correct "IP Address" before they click on the "Submit" button... How can I achieve it?

Thanks.

Sounds like you're trying to implement a masked textbox, which is a textbox that auto-format data as the user types according to a specified pattern. Check this tutorial on how to implement this, since is not featured in WPF out-of-the-box: Masked TextBox in WPF

The following question link on StackOverflow contains a lot of pointers to MaskedTextBox implementation in WPF. You can use it to get IP Address input from user.

Where can I find a free masked TextBox in WPF?
