In autocomplete mode(combobox) suggested items is not complete

Question

I am using ComboBox to show email-Id list. I have used the Dropdown style. For suggestion I have used AutoComplete mode.

Problem : All results will showing at the time of suggesting items(type some starting keys).

Here code snippet :

  'AutoCompleteStringCollection combData = new  AutoCompleteStringCollection();
    combData.AddRange(ComboItems);

    combo.AutoCompleteCustomSource = combData;
    combo.Sorted = true;

    combo.AutoCompleteSource = AutoCompleteSource.CustomSource;
    combo.AutoCompleteMode = AutoCompleteMode.SuggestAppend;

   m_cmbNode.DropDown += (sender, e) => m_cmbNode.AutoCompleteMode = AutoCompleteMode.None; m_cmbNode.DropDownClosed += (sender, e) =>         m_cmbNode.AutoCompleteMode = AutoCompleteMode.SuggestAppend;'

我在列表项中使用了一些特殊字符，我无法识别确切的字符，因此错过了列表中的最后一项。
