Copying listview row without duplication

[walidm38]

Hi,

Trying to copy a ListView row to another listView control and to prevent having duplicates I'm checking if the item already exists first.
If the row doesn't exist then copy it if not don't do anything.
My code doesn't seem to work and thinks the row does't exist all the time.
could someone tell me where I am going wrong?
Thanks and advance.

private void CopyChecked ( ListView sourceListView, ListView destListView )
{
foreach ( ListViewItem item in sourceListView.Items )
if (item.Checked)
{
if (CheckIfListViewItemExistsInListView(item,destListView)==false)
{
destListView.Items.Add(item.Clone() as ListViewItem);
}
}
}



------------------------
private bool CheckIfListViewItemExistsInListView(ListViewItem itemToAdd, ListView destListView)
{
bool exists = false;
foreach (ListViewItem item in destListView.Items)
{
if(item == itemToAdd)
{
exists=true;
break; // Break the loop if the item found.
}
}
return exists;

}
