Removing the ‘Add Existing [Entity] to this record’ button

This content comes from here: http://blog.davehawes.com/post/2008/04/23/MSCRM-4-Remove-Add-Existing-xxxxx-button.aspx. I have reproduced it here because it is really handy and I don’t want to loose it.

Take note: Strictly speaking this is unsupported (and the previous method for doing this broke when upgrading ver 3 to ver 4). Apparently they are going to provide a supported way for doing this in the future. Use knowingly…

Thanks Dave Hawes!

HideAssociatedViewButtons =  function(loadAreaId, buttonTitles){
//--------------------------------------------------------------------------------------------------

    var navElement = document.getElementById('nav_' + loadAreaId);

    if (navElement != null)    {

        navElement.onclick = function LoadAreaOverride() {

              // Call the original CRM method to launch the navigation link and create area iFrame     

              loadArea(loadAreaId);           

              HideViewButtons(document.getElementById(loadAreaId + 'Frame'), buttonTitles);

        }

    }

};

//--------------------------------------------------------------------------------------------------
HideViewButtons=function(Iframe, buttonTitles) {
//--------------------------------------------------------------------------------------------------

    if (Iframe != null ) {

        Iframe.onreadystatechange = function HideTitledButtons() {

            if (Iframe.readyState == 'complete') {

                var iFrame = frames[window.event.srcElement.id];

                var liElements = iFrame.document.getElementsByTagName('li');

                for (var j = 0; j < buttonTitles.length; j++) {

                    for (var i = 0; i < liElements.length; i++) {

                        if (liElements[i].getAttribute('title') == buttonTitles[j]) {

                            liElements[i].style.display = 'none';

                            break;

                        }

                    }

                }

            }

        }

    }

} ;

To hide just the add existing btton the call is this:
HideAssociatedViewButtons('lwb_contact_lwb_service', ['Add existing Program to this record']);

To hide both buttons the call is this:
HideAssociatedViewButtons('lwb_contact_lwb_service', ['Add existing Program to this record', 'Add a new Program to this record']);

replace the bold bits with:
[Customisation Prefiix] + “_” + [Entity Schema Name] + “_” + [Customisation Prefiix] + [Entity Schema Name]

and Program with the Entity Display name
