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

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 );

Scott.

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.

Hi, I'm trying to populate a TreeView from an existing and filled in ListView (lvwBuild). lvwBuild is a basic two column listview which can have any number of rows. I would like the first column of lvwBuild to be a node and the second column to be a branch on the TreeView (hopefully I have the syntax correct). I've been researching how to do this but have come up empty. I'm guessing that you would fill an array from lvwBuild and...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
