Hello!

Is there a possibility to add own text ( instead of automaticly generated ) to this kinf of grid cell? Or I’ll have to create my own class derived from CExtGridCell?

I’m currently trying to implement such class:



class  CExtGridCellTextColor : public CExtGridCellColor

{

    DECLARE_SERIAL( CExtGridCellTextColor );

    IMPLEMENT_ExtGridCell_Clone( CExtGridCellTextColor, CExtGridCellColor);



    CExtGridCellTextColor( CExtGridDataProvider * pDP = NULL);

   



public:

    ~CExtGridCellTextColor(void);

    virtual void OnFormatCellText( CExtSafeString &strText, COLORREF clr );

   

};

 

#include "StdAfx.h"

#include ".\extgridcelltextcolor.h"



IMPLEMENT_SERIAL( CExtGridCellTextColor, CExtGridCellColor, VERSIONABLE_SCHEMA|1 );



CExtGridCellTextColor::CExtGridCellTextColor( CExtGridDataProvider * pDP /* = NULL */ )

    : CExtGridCellColor( pDP )

   

{

   

}



CExtGridCellTextColor::~CExtGridCellTextColor(void)

{

}



void CExtGridCellTextColor::OnFormatCellText( CExtSafeString &strText, COLORREF clr )

{

   

    if( clr == RGB( 100, 100, 100 ) )

    {

        strText = L"SomeText";

    }

   

}

but function "OnFormatCellText" is never beeing called ( constructor is ).

 

Here is the declaration of OnFormatCellText:

virtual void OnFormatCellText(
            CExtSafeString & strText,
            COLORREF clr
            ) const;

As you can see the signature of your overridden method is different. You missed the const attribute. That is why you method is not invoked.

Thanks!

The color cell’s text is generated in the CExtGridCellColor::OnFormatCellText virtual method. You can create your own CExtGridCellColor-derived class and override this method there.
