I met a strange problem with XTP 11.2.1. I inserted a propertygrid on a pane, and I also created a CXTListCtrl on that pane. I could catch the notification message through OnGridNotify() when I clicked the standard grid items. Then I inserted some custom button as grid item into the propertygrid(same as GridSample) , but I couldn't catch the notification message through OnGridNotify() when I clicked custom button.

 

What's the problem...?

 

some of my code:

 

BEGIN_MESSAGE_MAP(CPropertiesPane, CWnd)
     ......

     ON_MESSAGE(XTPWM_PROPERTYGRID_NOTIFY, OnGirdNotify)

END_MESSAGE_MAP()

 

LRESULT CPropertiesPane::OnGirdNotify(WPARAM wParam, LPARAM lParam)
{
     int nGridAction = (int)wParam;

     .....

}

 

int CPropertiesPane::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
    if (CWnd::OnCreate(lpCreateStruct) == -1)
       return -1;

  

    ......

    if (m_wndPropertyGridPart.GetSafeHwnd() == 0)
    {
        m_wndPropertyGridPart.Create(CRect(0, 0, 0, 0), this, 0xf0);
        m_wndPropertyGridPart.SetOwner(this);
        m_wndPropertyGridPart.SetTheme(xtpGridThemeDefault);
        m_wndPropertyGridPart.ShowHelp(FALSE);

    .....
}

Why standard buttons have to send messages to OnGridNotify??? They send them to its parent.

 

Thank you for your reply. Actually, they are not standard buttons. These custom buttons are propertygrid items derived from CTXPropertyGridItem. I copied this class from GridSample shipped with XTP. This class is defined as below:

 

class CCustomItemButton : public CXTPPropertyGridItem
{
protected:

public:
 CCustomItemButton(CString strCaption, BOOL bFullRowButton, BOOL bValue);

 BOOL GetBool();
 void SetBool(BOOL bValue);

protected:
 virtual BOOL IsValueChanged();
 virtual void SetVisible(BOOL bVisible);
 BOOL OnDrawItemValue(CDC& dc, CRect rcValue);
 virtual void OnIndexChanged();
 void CreateButton();

private:
 CInplaceButton m_wndButton;
 BOOL m_bValue;
 CFont m_wndFont;
 CString m_strButtonText;
 BOOL m_bFullRowButton;

 friend class CInplaceButton;
};

 

I created this grid items as following code:

 

CXTPPropertyGridItem* pCustomItem = m_wndPropertyGridPart.AddCategory(_T("Test Button"));
   pCustomItem->AddChildItem(new CCustomItemButton(_T("Update"), TRUE, TRUE));

 

But GridSample hasn't this kind of problem, it can catch notify message when the button grid item is clicked through OnGirdNotify(). I do the same as GridSample, but I can get the same result.

 

By the way, I update these grid items dynamically. This mean I will remove or add some items according to some rules. I use a function UpdateGrid() located in CMainFarme to do this (update grid items).

BEGIN_MESSAGE_MAP(CInplaceButton, CXTButton)
 ON_CONTROL_REFLECT(BN_CLICKED, OnClicked)
 ON_WM_SETCURSOR()
END_MESSAGE_MAP()

void CInplaceButton::OnClicked()
{
 m_pItem->m_bValue = !m_pItem->m_bValue;
 m_pItem->OnValueChanged(m_pItem->GetValue());
 
 SetChecked(m_pItem->m_bValue);
}

check that you have same.

 

Hi, Oleg,
