我有一个组合框，我想在选择组合中的项目时显示不同的字符串.

我的组合框是一个下拉组合框.

例如:我的组合框中有以下内容.

亚历克斯-经理

雨-项目负责人

Shiney-工程师

Meera-高级工程师

在选择组合框中的项目时，我只想显示名称，即Alex.

我能够实现我的要求OnComboSelChange()和Arrow Keys事件，但是在组合框中使用箭头键后按Enter键时，它不会在组合框中显示格式化的文本.

我尝试过的事情:

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);
}
