Hi
Sir Good morning
I am using string builder class to store the dropdown selected values ..
I am doing this on the selected index change event
the problem is the previous value does not retain
sb.Append(degreedropdown.SelectedValue+"-");
string nums = sb.ToString();
string pattern = "-";
string[] substrings = Regex.Split(nums, pattern);
arraylength = substrings.Length;
