How far did you look until you came to that conclusion?
I have spend two days four days before posting this topic and an other two day after posting it just trying to find out this first part.
"Drop down box 1 will be filled from Table 1 (subject)
Drop down box 2 is filled from Table 2 based on what subject is selected in Drop down box 1"
Note: I am trying to do this first part on one page.
I have already found a way I can do this with ASPX using updatepanel but I have not coded it yet, as I am now trying to work out now to connect ASPX using C# to a database. This is proving to be harder in C# and ASPX.
