Dear Support,

I have a grid derived class which i initialize to have one header row on the left side, and one at the top.
I would like to access the top-left cell for writing something in it.

How do I do it?

Thanks,
Ron.

Support’s answer to this one from a previous post:
The grid control does not display cell objects in corners but you can repaint them if you need to display some information there. You should override the CExtGridBaseWnd::OnGbwEraseArea() virtual method like as follows:

void C_YOUR_GridWnd::OnGbwEraseArea(CDC & dc, const RECT & rcArea, DWORD dwAreaFlags) const
{
	ASSERT_VALID( this );
	ASSERT( dc.GetSafeHdc() != NULL );
COLORREF clrDebugFill = COLORREF( -1L );
	switch( dwAreaFlags )
	{
		case __EGBWA_OUTER_CELLS|__EGBWA_OUTER_TOP: clrDebugFill = RGB( 255, 128, 128 ); break;
		case __EGBWA_OUTER_CELLS|__EGBWA_OUTER_BOTTOM: clrDebugFill = RGB( 128, 255, 128 ); break;
		case __EGBWA_OUTER_CELLS|__EGBWA_OUTER_LEFT: clrDebugFill = RGB( 128, 128, 255 ); break;
		case __EGBWA_OUTER_CELLS|__EGBWA_OUTER_RIGHT: clrDebugFill = RGB( 128, 255, 255 ); break;
		case __EGBWA_OUTER_CELLS|__EGBWA_OUTER_LEFT|__EGBWA_OUTER_TOP: clrDebugFill = RGB( 255, 128, 255 ); break;
		case __EGBWA_OUTER_CELLS|__EGBWA_OUTER_LEFT|__EGBWA_OUTER_BOTTOM: clrDebugFill = RGB( 255, 255, 128 ); break;
		case __EGBWA_OUTER_CELLS|__EGBWA_OUTER_RIGHT|__EGBWA_OUTER_TOP: clrDebugFill = RGB( 255, 255, 128 ); break;
		case __EGBWA_OUTER_CELLS|__EGBWA_OUTER_RIGHT|__EGBWA_OUTER_BOTTOM: clrDebugFill = RGB( 128, 128, 128 ); break;
		case __EGBWA_INNER_CELLS: clrDebugFill = RGB( 255, 255, 224 ); break;
	}
	if( clrDebugFill != COLORREF( -1L ) )
		dc.FillSolidRect( &rcArea, clrDebugFill );
}
