Creating an item(Under the key) is easy,but how to add subitems(Value)?
listView1.Columns.Add(\"Key\"); listView1.Columns.Add(\"Value\"); listView1.Items.Add
add:
.SubItems.Add("asdasdasd");
to the last line of your code so it will look like this in the end.
listView1.Items.Add("sdasdasdasd").SubItems.Add("asdasdasd");
