Using the code

Just make a overload constructor which takes parameters of the window in which you want to retrieve value.

Example:

Suppose we want a user to login from our MainWindow( i.e Login Window ) and

we want to pass an int ID / string Email to our second form to retrieve data of logging user.

Than We have to first overload our second wpf form constructor.

You can either make default constructor to do this or make an overload constructor for this work.

SecondForm:

Hide   Copy Code

public secondForm()
 {

    //Your Default Constructor Logic 

 } 

public secondForm(string email_ ) 

 {    
   //Your Overload Constructor Logic
 }

Now in MainWindow from where we are logging and passing our EMail

MainWindow:

Hide   Copy Code

public void btnLogin()
 { 

     //On Success

     SecondWindow sw = new SecondWindow(txtBoxEMail.Content); 
     sw.Show(); 

  }
