if it's

Code Snippet

foreach (ListViewItem item in listview2.Items)

 

 

 

 

when ever this code runs, it should add items from listview2 to listview3.

 

what do you mean by 'it wont work'?

 

nothing added? have you debugged into the code to see if the code is executed, if listview2 contains item?

Answer 2

 

You can't add a ListViewItem to a ListView with it is already a part of another ListView.

 

You need to Remove the item from the source list before sending it to the target list.

 

foreach (ListViewItem item in listView1.Items)

{

listView1.Items.Remove(item);

listView2.Items.Add(item);

}

Answer 3

way do i have to remove the item from listview1?

or do u have a better solution?

 

//thanks best reggards!!

 

Answer 4

If you want to copy the item, rather than removing it, create a new instanse of the ListViewItem, set its properties to the source item and add it to the target list.

Hi Dani,

Yes, like Gazit said, you need a new instance of ListViewItem. And the ListViewItem has a method named ‘Clone’ which allows you to create an identical copy of the item. Try something like the following:

Code Snippet

            foreach (ListViewItem item in this.listView2.Items)

            {

                this.listView3.Items.Add((ListViewItem)item.Clone());

            }

 

I assume your listView2 and listView3 have the same columns.
