C# :: Get Item From List In Another Class

How can I get the items from a list into textboxes. I am doing an windows form application in visual studio.

I have the first form with a couple of textboxes.

I want the inputs be saved in a list. And then displayed in another form. How to move on. The class with the list looks like this:

public class Casecs {
public List<caseInformation> fallInformation = new List<caseInformation>();
public class caseInformation {
public string caseId { get; set; }
public string phoneNumber { get; set; }
public string description { get; set; }
}

Then the form with the inputs in textboxes looks like this:

Casecs Casecs = new Casecs();
Casecs.fallInformation.Add(new ERIS.Casecs.caseInformation {
caseId = txtCaseId.Text,
phoneNumber = txtPhonenumber.Text,
message = txtMessage.Text
});

Then where I am stuck a form with some textboxes where I want the list items to be displayed:

public partial class btnDispatch : Form {
public btnDispatch() { }
public btnDispatch(List<Casecs.caseInformation> fallInformation) {
InitializeComponent();
