No notification message from custom button

 

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);

    .....
}

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,
