How to add together the selectedvalues from 2 radiobuttonlist controls and show the result in a textbox?
Posted on 2006-06-19
If I have these radiobuttonlist controls on my form:
radNumber1 (options are 0, 1, 2, 3, 4, 5)
radNumber2 (options are 0, 1, 2, 3, 4, 5)
and this textbox on my form:
how can I add together whatever was selected for radNumber1 and radNumber2, and show the result in txtAnswer?
A couple things in particular:
- I need to only show the result when they have picked something for BOTH radNumber1 and radNumber2 (meaning, neither can have no selection)
- If they picked something first, and the sum showed up in the textbox already, but then they change their mind and pick something else for either one or both of the radiobuttonlists, I need to txtAnswer sum to automatically recalculate and show the correct sum for the new selections.
