ListViewCombobox ItemDropDownWith

How can I set the width of the DroppedDownItems in the property editor?

I have solved this problem by the following code:

private void listViewComboBox1_DropDown(object sender, EventArgs e)
{
ListViewComboBox listViewComboBox = sender as ListViewComboBox;
listViewComboBox.ListView.Width = 500;
listViewComboBox.ListView.Invalidate();
}
