How to prevent duplicate data from TextBox in C#?

-------------Problems Reply------------

The ListView class provides a few different methods to determine if an item exists:

Using Contains on the Items collection Using one of the FindItemWithText methods They can be used in the following manner:

// assuming you had a pre-existing item
ListViewItem item = ListView1.FindItemWithText("test");
if (!ListView1.Items.Contains(item))
// doesn't exist, add it

// or you could find it by the item's text value
ListViewItem item = ListView1.FindItemWithText("test");
if (item != null)
// it exists
// doesn't exist

// you can also use the overloaded method to match sub items
ListViewItem item = ListView1.FindItemWithText("world", true, 0);
