My bad 

.
Attached is a sample of these items. In short:
Child Form Dialog Parameters
You simply pass a comma seperated list of values in the ShowDialog method, and format the constructor of the child dialog to match the values you pass.
So, on the parent:
childFormDialog1.ShowDialog("test",1);
Which means the constructor of the child should look like:
public MyDialog(string MyFirstParameter, int MySecondParameter)
{
    InitializeComponent();
    
    //-- Do something with the parameters
    this.Text = MyFirstParameter;
    cboMyCombo.SelectedIndex = MySecondParameter;
}
StrataListView Enhancements
Both of these are simply properties of the StrataListViewSubItem and StrataListViewItem respectively.  Here is a block of code from the attached sample app that demonstrates this:
  _Item = new StrataListViewItem("Green", "");
  _Item.AdditionalItemHeight = 20; //-- Here is the additional height
  _SubItem = new StrataListViewSubItem();
  _SubItem.BackgroundColor = Color.DarkGreen;  //-- Here is the background color
  _SubItem.TextColor = Color.White;
  _SubItem.Text = "Value 3 - Additional height to show               Two rows of text.";
  _Item.SubItems.Add(_SubItem);
  slvMyListview.Items.Add(_Item);
Hope it helps!
