I tried but It didnt worked.  

I think I didnt explained it properly. Let me try again. I have a page, where I have 4 databound dropdownlist control and at the bottom I have detailsview form which displays only one value (parm_value). I want to use detailsview form so that I can easily edit the value without writting much of a code.

The select parameter for detailview has two parameter, i.e. the previous 2 dropdownlist.

But the update command (store procedure) has  5 parameters.  i.e the 4 selected value in the dropdownlist and the edited value in the form view.

I need help with writting the update parameters. My Selectcommand works fine.

Any help will be greatly appreciated.

Thanks
