I have a survey page. basically there are like 40 questions, each question can be answered with a numerical value of 1 through 6. We are using sliders to let people choose the answer to each question.
I would like to use something like an <asp:RequiredFieldValidator /> to make sure the user chooses a value between 1 and 6.
What we have actually done is set the minvalue on the slider to 0 and max value to 6, but we are considering a selection of 0 as a question that hasn't been answered. So basically I need to use a validation control to validate that the slider value is not 0. I need it to work like the builtin validation controls work, with a validation group, and client and server side validation support.
I know that I could set the slider range to 1 - 6, and then I could guarantee that I won't get any 0 values. But that is not an acceptable solution, we don't want people to select the default value, we want them to explicilty choose a value.
Is there anyway to do what I am asking for? The slider doesnt even have the standard ValidationGroup property.

Hello viscious,
Having a validation for RadSlider is in our ToDo list for one of the following versions of the control. For the time being, we can suggest to use a custom validator that would make the check on the server. For convenience I attached a small sample that shows this approach in action.
