Ajax UpdatePanel with Wizard

Hi, I have a Wizard that have about 5 steps and in every step (page) I do have some tables, checkboxes, gridview...etc and I'm trying to Cut and Paste this wizard into Ajax for Ajax enabling, but it's giving me this error: "The ActiveStepIndex must be less than WizardSteps.Count and at least -1. For dynamically added steps, make sure they are added before or in Page_PreInit event" and when I took out the step(page) that have my gridview in it every thing worked fine!!!? So, Why is that? Thanks

Thanks

Hi,

It's hard to tell why without knowing your code, since it may be caused by some logic problems in your code.

Can you post a sample without relying on a particular database and class ?

I'm getting this error in Design time not run time, meaning once I cut and past my wizard into an Updatepanel the error comes up!!?

Thanks
