k I have this 2 forms
reminderform.cs and List.cs
I have this button in the reminderform.cs
| Code: | private void Add_Click(object sender, EventArgs e){
List form2 = new List();
form2.ShowDialog();
string remindme = this.Reminder.Text;
form2.listBoxList.Items.Add(remindme) ;
this.Reminder.Text = "";
}
|
which does everything but add the new entry to the list in the other form
whats wrong ? X_x?
___________
forget it, I just discovered it was all about changing the button protection from private to public

| This is a terrible way to architect your program, perhaps you should consider designing your class structure.

This is how I do it:
| Code: |
public partial class List : Form
{
public void UpdateList (List<string> items)
{
foreach(string item in items)
listBoxList.Add(item);
}
}
public partial class form1 : Form
{
List form2 = new List();
List listToShow = new List<string>();
private void Add_Click(object sender, EventArgs e){
if(form2.IsDisposed)
form2.Show();
listToShow.Add(this.reminder.Text);
form2.UpdateList(listToShow);
this.Reminder.Text = "";
}
}
|
Edit:Fixed an error in the code.
