I have a summary row in my ultragrid, how do i hide the sum glyph displaying in the column header. I don't want my user to clik and change the sum to count or something else. Thanks...
Ensure that the AllowRowSummaries property is set to false. This can be set in a few different places: off the column directly, off the Override object for the band to which the column belongs, and off the grid's DisplayLayout.Override object.
This property controls only whether the sigma symbol (the glyph you've described) is shown, which provides the UI for an end user to summarize columns how they want. You can still apply summaries to the grid without exposing this UI.
