problems using page.databind when outputting values from an object

[mit99mh]

I'm using a page with several panels - I instantiate an object and using Page.DataBind(); in the subroutine in the codebehind and <%# Object.Value %> in the apsx page - so far so good.

I then change the value in the object and use the same approach as above Page.DataBind(); in the subroutine in the codebehind and <%# Object.Value %> in a different panel the apsx page and I get System.NullReferenceException: and the error points to the line where I call Page.DataBind(); the second time.

I've worked around this now but I'm curious why I should get the error in the first place.

Any help much appreciated

Did you check for IsPostBack on the Page load event?

Hope everyone is having a great day!

Thanks - Jennifer
