I am Created a grid and subgrid with jqgrid

but facing 2 issues

1, insert first row to the empty grid insertion successful but not highlight it.

2, after insert the first row. I am insert the second row inserted successfully. but

   id column is empty. why..?

I will check the column id. get result row count. not a row id. it change automatically row id to row count..?  

insert a row to the subgrid not valid because master grid id column is empty and id is row count instead of row id

anybody can help me
