The trouble with modigying the datagrid behavior itself is that you have to do that everytime you install a new version! It used to be you could copy the code in the script of the behavior button, paste it into a new button in your app then set the dg behavior to the new button ID, but that does not work anymore, on account of the way they are using script only stacks now.
I have inserted a custom behavior before the default behavior, but I have to make a couple mods in the script only behaviors to get them to work. This was discussed a while back, and someone figured out a way to get nested behaviors to work. I think they said that the hotfix will be bundled into 9.1, so then I won't have to customize the behaviors after that.
There is no "best practice" when it comes to these things. At best they are hacks, but the benifit outweighs the hazards, so we go for it.
As far as your dg not refreshing, if you already set the dgNumberOfRecords/lines, then the auto refresh of the datagrid will be turned off, and it won't refresh on it's own. (Someone may correct me on this).
Redraws row associated with pIndexes using latest data. Use this command in conjunction with SetDataOfIndex. pIndexes can be a comma delimited list of indexes.
Redraws row using latest data. Use this command in conjunction with SetDataOfLine. pLines can be a comma delimited list of lines.
