We have the same situation come up here today. We have rowdetailstemplates that may have any number of rows. We don’t want to display 200px when there is just one row and at the same time display only what fits in 200px when there are 100 rows and have the user have to scroll. Autosize would be a big help.
I’m thinking we could get the nested grid height if it is set to be autosize : ‘true’ and then change the container height to be the same or slightly larger using jquery. Do you think this wil work?
