Question

I have an WPF form with 3 textbox named FirstName LastName and GPA, and i want to check their content before inserting into the database. But i am trying to do this in another class. How can i make to access the textbox control from my class? the WPF window is named AddStudent and the class i want to make the check is named Consiste. I made Consiste static so i can use it on my AddStudent without creating an instance.

In you Util class, you must just have method with input parameter

public static bool Validate(string firstName, string lastName,string gPA)
{
   if(firstName.Length < 1)  
   .....

   return true;
}

And call this static class Util

Util.Validate(FirstName.Content, LastName.Content, GPA.Content);
