View 12 RepliesI am filling a listview control with a big number of items but i came across an problem, the repeated values.

I have been trying to use the items.find() with no luck since it looks like to search for keys, which i don't really have. Every item has different .Tag values but it can happens that they have the same .Text Is there any way to remove or just not add items based on a .Text search in the ListView?

Ok, so I have a listview on one form, and when a button is pressed it opens up a new form with the contents of the selected listview item and it's subitems in a series of textboxes. The user can then change the data in the textboxes and either press save to make the changes or cancel to close the window. What command would I use to change the selected listview item and subitems to whatever is in the boxes?
this is the code that populates the boxes:

Dim appeditcontents As String = main.passlist.SelectedItems(0).ToString

I have a media browser program I am building. I am trying to use drag/drop so a user can drag media tracks from one listview to another listview and then use the second list view as a playlist in windows media player com object. Reading at MSDN I have found out that there is no built in support for item re-ordering with the listview control. I have listview1 working correctly but when I try to reorder items in listview2, the dragged item ends up at the end of the list. So basically I need to get the item insertion index corrected. I have tried more than 10 times to get this code right.
Here is my code which includes a form with two listview's.
