I have a gridview which consists of 3 columns of dropdownlist, which these 3 dropdownlist are inter-related, means the 2nd dropdownlist will depends on the 1st dropdown value, where the 3rd dropdownlist will depends on the 2nd dropwdown value.
My problem is when editing the row, I am not able to list the 2nd dropdownlist (drp Responsibility) according to the selected drp Application dropdown and the same for 3rd dropdownlist (drp Function) which only listed value according to the selected value in drp Responsibility.
