Listbox items with ToString override, display problem

[jespermohl]

My listbox displays an empty string when I add an form to it.
I tried to override ToString and set listbox.DisplayMember to a property.
It works when i use lbxHeader1.Items[1].ToString();

Does anybody have a clue what could be wrong?


This is my definitions:

public partial class TextDisplay : Form​

{​

public override string ToString() {...}​

}​

partial class Form1​

{​

this.lbxHeader1 = new System.Windows.Forms.ListBox();​

}​

public partial class Form1 : Form​

{​

private void lbxHeader1_MouseDoubleClick(object sender, MouseEventArgs e)​

{​

TextDisplay TextDispDialog = new TextDisplay();​

lbxHeader1.Items.Add(TextDispDialog);​

}​

}​

What does the actual code for the public override string ToString() {...} method look like?
