Hello Reena,

The only reason we can think of is if you have changed the report viewer template and it is corrupted. If that is the case, please use the default template or re-edit it in Blend, making sure it is correct.
Also please review the following articles that elaborate on proper deployment:

Hello Reena,

Container items (sections and Panel report item) cannot shrink automatically. That is why, you can manually set the Height of the section/item to a very small value in the report constructor right after the InitializeComponent() method. This would make sure that the report grows only as much as necessary whenever you hide items.

Kind regards,
