Hi thabiso007,

Can I suggest you consider researching about some OOP concepts because from reading your code it seems evident you're unsure of the notion of "objects". This is a crucial and fundamental part of any OOP language like C# and without it you will find yourself making these same mistakes over and over just with different classes. :)

Solution 3

This code should do the trick:

lstDataList.Items.Add(txtData.Text);

However, you should really be careful about duplicate entries, as this code does not check for duplicate entries.
Hence,

if(lstDataList.Items.Contains(txtData.Text)==false)
{
   lstDataList.Items.Add(txtData.Text);
}
