c# - combox box error -

- 

private void combobox1_selectedindexchanged(object sender, eventargs e)     {         combobox combo_design = new combobox();         combo_quality.items.add("best");         combo_quality.items.add("normal");         combo_quality.items.add("draft");          combo_quality.text = "best";          messagebox.show(combo_quality.text);          string selecteditem = combo_quality.items[combo_quality.selectedindex].tostring();           combo_quality.text = "normal";          messagebox.show(combo_quality.text);          string selecteditem2 = combo_quality.items[combo_quality.selectedindex].tostring();           combo_quality.text = "draft";          messagebox.show(combo_quality.text);          string selecteditem3 = combo_quality.items[combo_quality.selectedindex].tostring();         }

this relates combo box, have 3 items select want when choose best message box pops out , let me select ok , same goes normal , draf

if want alert selected text, could:

messagebox.show(combo_quality.selecteditem.tostring());

if want confirm , allow user cancel selection question: how prevent/cancel combobox's value change in c#?
