TypeError: Cannot read property 'setVisible' of null
at showhide (hungerstation-sandbox.crm4.dynamics.com/.../new_showhidtabsoncase)

//parent.Xrm.Page.ui.tabs.get("ContentUpload").setVisible(true);
parent.Xrm.Page.ui.tabs.get("general").sections.get("ContentUpload").setVisible(true);

Hi,

why you add parent every time ?

try this code please

function showtab()

{

if(Xrm.Page.getAttribute("field").getValue()!=null)

{Xrm.Page.ui.tabs.get("tabname").sections.get("tabname_section_name").setVisible(true);}

else

{Xrm.Page.ui.tabs.get("tab_2").sections.get("tab_2_section_3").setVisible(false);}

}

Hi Ahmad,

On which event you are adding code. Because first write console.log(parent.Xrm.Page.ui.tabs.get("general")) and check any of your object should not listed as null. It looks like when you are assessing tab object it was null.

so make sure at time when you access object should has value.

Mark as verified if helps !!

Thanks,

Sandeep

Hi Ahmed ,

Not sure why its not working ,ideally this should work. I found some additional brackets in previous posted code try with this -

function showhide() { if(Xrm.Page.getAttribute("subjectid").getValue() == "ContentUpload") { Xrm.Page.ui.tabs.get("TabName").sections.get("SectionName").setVisible(true); // Make sure you are providing correct sectionname , tab name } else { Xrm.Page.ui.tabs.get("TabName").sections.get("SectionName").setVisible(false); // Make sure you are providing correct sectionname , tab name } }
