In the standard MFC CListCtrl class, there’s a method called SetItemData that allows the programmer to assign any application-specific value to a particular row. Is there something like this in the CExtGridWnd class?

The CExtGridWnd control works with a number of CExtGridCell objects organized into a two dimensional matrix of columns and rows. If you need to assign custom data to a row, create a cell class that contains application-specific data and use it in grid columns that can be either data columns or header columns. It is handy to use a zero-width header column in your case:

wndGrid.OuterColumnCountLeftSet( 1L, false );
wndGrid.OuterColumnWidthSet( true, 0L, 0 );

CExtGridCell * pCellHeaderAtLeft =
   wndGrid.GridCellGetOuterAtLeft(
      0L,
      nRowNo,
      RUNTIME_CLASS(
         C_YOUR_GridCellHeader
   )
);
ASSERT_VALID( pCellHeaderAtLeft );

Thanks, that was very helpful, and should work out well!

On another note, how do you format your code blocks in posts with the courier font and the gray background? I’d like to do that in the future to make my posts more readable.

Thanks again!

You can easily post code blocks using these HTML tags:
<code><pre>
Your code (courier, gray background)
</pre></code>
