Hi All,

Thank you in advance for your help on this. I have been combing through the forums and found several answers related to my situation but they weren't helpful. Below is the code in question and I don't see why this error should be coming up. I am using CRM 2013 Online and while I changed and deleted a couple of fields, as well as re-purpose an existing sub-grid, I did not change the name of any of the tabs?

function hideTab (tabName, visible)
{
Xrm.Page.ui.tabs.get(tabName).setVisible(visible);
}

check whether tab exists or not before setting the visibility

Something like below should work

function hideTab (tabName, visible)

{

if(Xrm.Page.ui.tabs.get(tabName) != null && Xrm.Page.ui.tabs.get(tabName) != 'undefined')

Xrm.Page.ui.tabs.get(tabName).setVisible(visible);

}

Hi David,

To hide tab, you need to use tab Name

also, javascript is case sensitive, so if your tab name is agent and you specified Agent, then also it will throw error.

One more thing always check for object before changing property..

function hideTab (tabName, visible)
{

var tab = Xrm.Page.ui.tabs.get(TabName);

if(tab ! =null)

{
tab.setVisible(visible);

}
}

Hope this will help..

Thank you so much Chitra, I tried your code first to see if that would work and it did!
