I have a CExtGridCellPicture in a CReportGridWnd and I want the set the row height for each row to the actual size of the picture?

The row height for each row could be different depending on the image.

I do not allow the row height to be resized through drop and drag.

You should invoke the BestFitRow() method after all its cells, including pictures, were initialized.

BestFitRow takes the row number and I have the CExtReportGridItem.

How can I get the RowNumber?

When is the best time to call BestFitRow? Should I just call it every time I update and item in the grid?

I have and UpdateItem Function that roughly follows

Update the item from ReportGridItem

ReportSortOrderUpdate

Actually the question is how to convert a CExtReportGridItem object into the row number so it can be used in the BestFitRow() method. If so, you can do this using the CExtTreeGridWnd::ItemGetVisibleIndexOf() method:

LONG nRowNo = ItemGetVisibleIndexOf( *pRGI );
