I have a combobox in that I want to display different string on selecting an item in Combo.

My combo box is a dropdown combobox.

For eg: I have following in my combobox.

Alex - Manager

Rain - Project Lead

Shiney - Engineer

Meera - Senior Engineer

OnSelecting an item in combobox I want to diaply only name i.e. Alex.

I am able to achieve my requirement OnComboSelChange() and Arrow Keys event but on pressing enter key after using arrow keys in combo box, it is not showing formatted text in combo box.

What I have tried:

struct details{
CString name;
CString des;
};

BOOL CComboTestDlg::OnInitDialog()
{
CDialog::OnInitDialog();

details d1;
d1.name = _T("alex");
d1.des =_T("manager");
m_vec.push_back(d1);

details d2;
d2.name = _T("Rain");
d2.des =_T("Engineer");
m_vec.push_back(d2);

// TODO: Add extra initialization here
for(int i=0;i<m_vec.size();i++)
{
m_ctrlCombo.AddString(m_vec[i].name+m_vec[i].des);
m_ctrlCombo.SetItemData(i,(DWORD_PTR)&m_vec[i]);
}
m_ctrlCombo.SelectString(-1,m_vec[0].name);
m_ctrlCombo.SetWindowText(m_vec[0].name);

return TRUE;  // return TRUE  unless you set the focus to a control
}

void CComboTestDlg::OnCbnSelchangeCombo1()
{
int nItem = m_ctrlCombo.GetCurSel();
details* det = (details*)m_ctrlCombo.GetItemData(nItem);
PostMessage(SETCOMBOTEXT,IDC_COMBO1,(LPARAM)(LPCTSTR)det->name);
}

BOOL CComboTestDlg::PreTranslateMessage(MSG* pMsg) 
{
MSG msg1=*pMsg;//I am loosing the value after  checking ..so storing temp.
MSG msg;
CopyMemory(&msg, pMsg, sizeof(MSG));
HWND hWndParent = ::GetParent(msg.hwnd);
while (hWndParent && hWndParent != this->m_hWnd)
{
msg.hwnd = hWndParent;
hWndParent = ::GetParent(hWndParent);
}
if (pMsg->message==SETCOMBOTEXT && (pMsg->wParam == IDC_COMBO1))
SetDlgItemText(IDC_COMBO1, (LPCTSTR)pMsg->lParam);
if(pMsg->message==WM_KEYDOWN)
{
if(pMsg->wParam==VK_RETURN && msg.hwnd ==m_ctrlCombo.m_hWnd )
{
OnCbnSelchangeCombo1();
}
} 
return CDialog::PreTranslateMessage(pMsg);
}
