For moving the items from one list view to another try this below..

private static void MoveSelectedItems(ListView source, ListView target) 
{   
  while (source.SelectedItems.Count > 0) 
  { 
    ListViewItem temp = source.SelectedItems[0]; 
    source.Items.Remove(temp); 
    target.Items.Add(temp); 
  }       
}

There are a couple of different ways.

If you want to copy the items from a to b:

private static void CopySelectedItems(ListView source, ListView target)
{
  foreach (ListViewItem item in source.SelectedItems)
  {
    target.Items.Add((ListViewItem)item.Clone());
  }
}

If you want to move the items from a to b:

private static void MoveSelectedItems(ListView source, ListView target)
{   
  while (source.SelectedItems.Count > 0)
  {
    ListViewItem temp = source.SelectedItems[0];
    source.Items.Remove(temp);
    target.Items.Add(temp);
  }       
}

hope this might help you

where i call this method and how pass source and destination
Ravi Maurya replied to msakt on 04-Jun-12 09:21 AM
you can call these methods on any event say click event of Button 

and pass the source control id with target control id 

for eg. CopySelectedItems(lvsource, lvtarget);
Try this and let me know

Hi..

You can also drag & drop item from one listview to another listview & another to one.

show below code sample
------------------

private void listView1_DragDrop(object sender,System.Windows.Forms.DragEventArgs e)
{
string textBox1 = e.Data.GetData(DataFormats.Text).ToString();
string[] items = textBox1.Split(',');
listView1.Items.Add(new ListViewItem(items,0));
lv1_mdown = false ;
lv2_mdown = false ;
}

private void listView2_DragDrop(object sender,System.Windows.Forms.DragEventArgs e)
{
string textBox1 = e.Data.GetData(DataFormats.Text).ToString();
string[] items = textBox1.Split(',');
listView2.Items.Add(new ListViewItem(items,0));
lv2_mdown = false ;
lv1_mdown = false ;
}

hi,

Try below code:

protected void ListView1_OnPreRender(object sender, EventArgs e)
{
    if (ListView1.EditIndex > -1)
      {
      // for avoid error
        }
      else
      {
        TextBox tb = null;


        foreach (ListViewDataItem item in ListView1.Items) {
            tb = (TextBox)item.FindControl("txtInsideId");

            if (tb.Text != null) {
                txtOutsideId.Text = tb.Text.ToString;
            }
        }

    }

}

Regards,
