Dear All,
Currently I am doing a debugging task on ASP.Net page which was developed by someone else. I am using VS-2008 in Windows XP environtment. There is some peculiar (at least for me) which happens in the code. Let me explain here below.
There are, say for example, three ASP Dropdownlist box on the form. Value of the first DDList was with fixed data (hard coded), value of the second DDlist was fetched from database depends on selected value of the first, similar with the third which depends on selected value of the second. All the three are AutoPostBack=true. What happens here is that, after populating the second DDlist when i change the value of the second DDlist it triggers the "SelectedIndexChanged" event of the first DDlist and the third also triggers the same.I am not sure how this could happen.
Please have a look at the source code and code behind below: I badly need your help my friends.
