Hi! I have a windows forms application.
I want to validate the text boxes data based on the data type in the database. Like for example i want to make sure that for the field zipcode, the data should only be integers and only be 5 digits. And also provide example for the validation of Nvarchar
data fields, so that it contains atleast one character.
Please show me the 2 examples that i mentioned using C#.
