I have tried a lot and i think that there is problem with control .
in My form i have Matrix
I have found that valid value are getting assign to column not cell because my requirement is to fill the valid value dynamically .
example in employee valid value
but if designation is manager then only (Mr.x and Mr.y should come ) and worker then (Mr.Z)
so i have set first row
srno Designation Employee
1 manager Mr.X
now when i set Mr Z in Second row then Mr. X Id is showing
2 Worker Mr.Z
please Check image
