Pass Value One Form to Another in WPF

Here i am showing how to pass value one form to another in WPF.

Just Open your App.xaml file and nevigate on App.xaml.cs file.

Here is you define the variable like this:

public partial class App : Application
{
     public string Id { get; set; }
     public string Roll { get; set; }
     public string Center { get; set; }
     //...what ever which you want in property

 }

Then after defining property in App.xaml.cs just access and set the value in property in another page like this.

public void Setvalue()// under the any function like this
{
   (App.Current as App).Id="Somevalue";
   (App.Current as App).Roll="Somevalue";
   (App.Current as App).Center="Somevalue";
}

Then after setting the value of property access on another page like this.

public void Getvalue()// under the any function like this
{
   string id=(App.Current as App).Id;
   string id=(App.Current as App).Roll;
   string id=(App.Current as App).Center;
}
