How to copy one listview to another. Hopefully this can help someone ;-)

[ltnats]

Hi guys,
I stuffed around with this for a whole day, searching the groups
and trying different methods. So when I finally came up with a solution
I thought I would share it, as it could save someone all the stuffing
round I had to do. Now I don't know if this will solve everyone's
listview copy situation, but it worked for me.

Here is the code:

ListViewItems[] LVIARRY_CopiedL istViewItems = new
ListViewItems[LV_FirstListVie w.Items.Count];

for (int INT_Count=0; INT_Count < LVIARRY_CopiedL istViewItems.Le ngth;
INT_Count++)
{
LVIARRY_CopiedL istViewItems[INT_Count] =
(ListViewItem)L V_FirstListView .Items[INT_Count].Clone();
}

LV_SecondListVi ew.Items.AddRan ge(LVIARRY_Copi edListViewItems );

did you try the Array.Copy() method work on this? Or does this create
a new instance of an array with references to the original ListItems?

James,
I did try that method, but I had the same problem as the poster
called "CaffeineRu sh" in this post:
---------------------------------------------------
http://groups.google.com/group/micro...294ffc72f62442

I go the same:
---------------------------------------------------
System.Argument Exception error in system.windows. forms.dll:

Additional information: Cannot add or insert the item 'filename.jpg' in
more than one place. You must first remove it from its current location
or clone it.
---------------------------------------------------
After a bit more research I then found this thread:
---------------------------------------------------
http://groups.google.com/group/micro...otnet.*&rnum=2

See where the poster "laurmo" says:
---------------------------------------------------
Basically it then turns out that the ListViewItemCol lection is then
just a reference to the ListView.Items data and any operation done on
one is
reflected on the other.
---------------------------------------------------

I am open to new ideas however?

Scott.
