Re: Asp.net Dropdownlist selected index in changed

hi,
first it would be useful to describe what you are trying to do. code is
helpful but it's no good unless you describe what you are trying to do with
it!

you say that the selected index of the first two dropdownlists are not
changed, are they supposed to change? in response to the user? or your
code?
you have this line of code in each bind method:
//reportCategoty_DropDownList.SelectedIndex=-1;
is it supposed to be uncommented?

happy to help if you can provide more info
