We are using the CExtPropertyGridCtrl for displaying the proprties
We have used the edit box type cell creation as below
CExtGridCellString *pValue =

STATIC_DOWNCAST(

CExtGridCellString,

ValueActiveGetByRTC( RUNTIME_CLASS(CExtGridCellString) )

);

pValue->TextSet(_T("Edit text"));

pValue->ModifyStyle( iStyle );



When user attempt to enter a decimal point while using the grid it does not accept that as input.

It accepts digits and alphabets but not the decimal point as input from the user.

However the grid allows setting the value to something like aˆ? 0.01aˆ? by using the TextSet method in the code.

We did modify the code and build it still the problem is there. Surprisingly it is working fine with sample application even without above changes. Identical code we added in our application and it is not accepting dot (.) character. It accepts all other special characters. Is there any method by which we can set property to enable this?

Please help.

The bug is fixed. Please open the CExtGridWnd::OnGbwBeginEdit() method and find the following code snippet at the end of the method:

if(    (!bCtrl) && (!bShift) && int(msg.wParam) == VK_DELETE )
{
    ::PeekMessage(&msg,NULL,msg.message,msg.message,PM_REMOVE);
    if( msg.message == WM_KEYDOWN )
    {
        LPTSTR strEmpty = _T(""); 
        INT nSelStart = 0, nSelEnd = 0;
        ::SendMessage( msg.hwnd, EM_GETSEL, reinterpret_cast < WPARAM > ( &nSelStart ), 
                 reinterpret_cast < LPARAM > ( &nSelEnd ) );
        if( nSelStart == nSelEnd )
            ::SendMessage( msg.hwnd, EM_SETSEL, WPARAM( nSelStart ), LPARAM( nSelStart + 1 ) );
        ::SendMessage( msg.hwnd, EM_REPLACESEL, 1, reinterpret_cast < LPARAM > ( strEmpty ) );
    }
    continue;
}

Please replace it with this

if(    (!bCtrl) && (!bShift) && int(msg.wParam) == VK_DELETE )
{
    if( msg.message != WM_CHAR )
    {
        ::PeekMessage(&msg,NULL,msg.message,msg.message,PM_REMOVE);
        if( msg.message == WM_KEYDOWN )
        {
            LPTSTR strEmpty = _T(""); 
            INT nSelStart = 0, nSelEnd = 0;
            ::SendMessage( msg.hwnd, EM_GETSEL, reinterpret_cast < WPARAM > ( &nSelStart ), 
                 reinterpret_cast < LPARAM > ( &nSelEnd ) );
            if( nSelStart == nSelEnd )
                ::SendMessage( msg.hwnd, EM_SETSEL, WPARAM( nSelStart ), LPARAM( nSelStart + 1 ) );
            ::SendMessage( msg.hwnd, EM_REPLACESEL, 1, reinterpret_cast < LPARAM > ( strEmpty ) );
        }
        continue;
    }
}

This bug is already fixed. Please open the CExtGridWnd::OnGbwBeginEdit() method and find the following code snippet

if(    (!bCtrl) && (!bShift) && int(msg.wParam) == VK_DELETE )
{
    ::PeekMessage(&msg,NULL,msg.message,msg.message,PM_REMOVE);
    if( msg.message == WM_KEYDOWN )
    {
        LPTSTR strEmpty = _T(""); 
        INT nSelStart = 0, nSelEnd = 0;
        ::SendMessage( msg.hwnd, EM_GETSEL, reinterpret_cast < WPARAM > ( &nSelStart ), reinterpret_cast < LPARAM > ( &nSelEnd ) );
        if( nSelStart == nSelEnd )
            ::SendMessage( msg.hwnd, EM_SETSEL, WPARAM( nSelStart ), LPARAM( nSelStart + 1 ) );
        ::SendMessage( msg.hwnd, EM_REPLACESEL, 1, reinterpret_cast < LPARAM > ( strEmpty ) );
    }
    continue;
}

Replace it with the following code

if(    (!bCtrl) && (!bShift) && int(msg.wParam) == VK_DELETE )
{
    if( msg.message != WM_CHAR )
    {
        ::PeekMessage(&msg,NULL,msg.message,msg.message,PM_REMOVE);
        if( msg.message == WM_KEYDOWN )
        {
            LPTSTR strEmpty = _T(""); 
            INT nSelStart = 0, nSelEnd = 0;
            ::SendMessage( msg.hwnd, EM_GETSEL, reinterpret_cast < WPARAM > ( &nSelStart ), reinterpret_cast < LPARAM > ( &nSelEnd ) );
            if( nSelStart == nSelEnd )
                ::SendMessage( msg.hwnd, EM_SETSEL, WPARAM( nSelStart ), LPARAM( nSelStart + 1 ) );
            ::SendMessage( msg.hwnd, EM_REPLACESEL, 1, reinterpret_cast < LPARAM > ( strEmpty ) );
        }
        continue;
    }
}

First of all, would you show what’s value of iStyle?
