Answer 1

There will be conflicts for every deleted row, so go with the below code:

>>

     for (int intCount = ListBox1.SelectedItems.Count - 1; intCount >= 0; intCount--) 
     {
        ListBox2.Items.Add(ListBox1.SelectedItems[intCount]);
        ListBox1.Items.Remove(ListBox1.SelectedItems[intCount]);
     } 

<<

     for (int intCount = ListBox2.SelectedItems.Count - 1; intCount >= 0; intCount--)
     {
        ListBox1.Items.Add(ListBox2.SelectedItems[intCount]);
        ListBox2.Items.Remove(ListBox2.SelectedItems[intCount]);
     }     

If the above one doesn't work then try this:

while (ListBox1.SelectedItems.Count > 0) 
{ 
    ListBox2.Items.Add(ListBox1.SelectedItems[0].Text);  
    ListBox1.SelectedItems[0].Remove(); 
}
