You can use this property to specify the height that the summary rows for this band or the grid controlled by this override will use. If the value of this property is lower than the MinSummaryRowHeight, it will be disregarded. Setting this property to 0 will cause the control to use the largest font size and image specified for the summary row to determine the its height.
Setting DefaultSummaryRowHeight to a value of -1 will cause it to use the value from the next highest object in the override hierarchy.
