I want to perform validations for TextBoxes in WPF.
Validations are like,
1) Checking Emptiness of a Control
2) validating Email Address
3) validating Mobile Number
I know How to handling all kind of validations in Asp.Net.
But Don't know in WPF.
Till now I am handling from code behind but I think that is not correct way.
I want to perform validations after Click Event just like in our Asp.Net.
Please give me your valuable suggestions.
