InitialToggleState in multi groups, reportviewer

Question

Hi Guys,

I am facing a bit issue with toggling result in ReportViewer. I have a multi groups in display result table [ 1). Date 2). Business Type 3).Business Category ]. In all cases, result always display expanded. I have set correct value at IntialToggleState = false and Hidden = false inside visibility Group. In case when I ask to collapse the toggle, report displays expanded result in first place. However, when I click on image, it works fine except displaying wrong image (+ -) .

Can you please guide me so result will be display as collapse when result load first time.
