jQuery Grid Plugin - jqGrid

Hi

I am using jqgrid inline with validation in grid using editrules . i want to add highlight error class (eg: ui-state-error) for the input which fails in validation .

i can able to set error highlight  class  like this

jQuery('#'+grid_id).jqGrid('setCell',row_id,errfields[a],'','ui-state-error',{color: 'blue'});

But this is not able to set when jqgrid trigger the info_dialog when validation fails .

how i add highlight the cell input  in grid validation .
