Problems with FileUpload Inside Customized CreateUserWizard

[IamAmit]

Hello friends, I am using a FileUpload Control inside Customized CreateUserwizard Control. I am accessing textboxes inside the CreateUserWizard as ((TextBox)BusinessDetWizardStep.FindControl("txtfirmsname")).Text.Trim(). I also put a fileupload inside this wizard. But while catching the file in code using this code if(((FileUpload)BusinessDetWizardStep.FindControl("fileupload1")).HasFile) { } The Fileupload control does not get any file to upload...Why this is happening? What could be the cause and solution for this? Thanks...

Are you using the fileupload within an updatepanel by any chance?

Thanks for the reply.. I am not using fileupload within UpdatePanel. The FileUpload is contained within WizardStep directly..
