I would like change the color for the current selection (cell, row, ... )

and highlighted row / column.

You should create a class derived from CExtGridWnd and override the OnSiwGetSysColor virtual method like this:

COLORREF CMyGridWnd::OnSiwGetSysColor( int nIndex ) const
{
    if( nIndex == COLOR_HIGHLIGHTTEXT )
        return RGB(255,255,255); // selected text
    if( nIndex == COLOR_HIGHLIGHT )
        return RGB(255,0,0); // selected background
    return CExtGridWnd::OnSiwGetSysColor( nIndex );
}

The grid control uses the system color indexes to get all colors. But it calls the OnSiwGetSysColor virtual method instead of ::GetSysColor() (Win32 API). So, this code changes the selected text and background colors to white and red.

Another way to change cell colors is to completely repaint the cell in your custom-defined cell class.

Thank you for your help,

I can not found the value for the parameter ’nIndex’ to manipulate the color for the row / column, which  highlight is enabled with the following flags:

__EGBS_EX_SI_HIGHLIGHT_COLUMNS
__EGBS_EX_SO_HIGHLIGHT_COLUMNS
__EGBS_EX_SI_HIGHLIGHT_ROWS
__EGBS_EX_SO_HIGHLIGHT_ROWS

__EGBS_EX_FI_HIGHLIGHT_COLUMNS
__EGBS_EX_FO_HIGHLIGHT_COLUMNS
__EGBS_EX_FI_HIGHLIGHT_ROWS
__EGBS_EX_FO_HIGHLIGHT_ROWS

 

 

The styles listed in your message are affected all rows and/or columns. If you want some particular row/column to be constantly (not depending on mouse hover, selected and focused cells), you need to override the grid/cell background painting code.
