C# :: Using ListView To Show Content (selected Item) In ComboBox?

I'm using listView to show content (selected item) in ComboBox, TextBox, Labels..

I was using

DropDownStyle = DropDown

and actually i use DropDownStyle = DropDownList.

With this change,

comboB.Text = Name;

stopped working correctly (onload), only work after first click any item. Why?

I tried too

private void comboB_KeyPress(object sender, KeyPressEventArgs e)
{
e.Handled = true;
}

but with copy/paste with mouse i can add text in ComboBox.

PS: My objective is combobox no editable.
