how to trigger subgrid load without opening subgrid


Is it possible from parent grid to trigger loading a subgrid without opening it?



You can open sub grid and then immediately close it:


It opens the subgrid for the last row only. and other rows shows empty. anything wrong i do?

Pleas,e make sure that you call open() method for the correct row ids.
Also please, note, that if you a re trying to open all the rows with a script it will be not available due to the callback absence of the open() method, as you are loading the data for the row from the external file.
