Is there any lookup
option in the grid, if yes what is the API for that? Should be something like,
I give string to search in specified column and it should return me row number
/ row id.


There
is next method:


           
findCell(value,c_ind)

which finds cell in grid by value in column  with index = c_ind. It
returns array of the results (row id and column index).
