Hiding Buttons in MSCRM 4.0

This weeks post comes from one of my co-workers. We've set up a number of solutions for clients where we hide a custom button or even the "Convert Lead" button.

If you have hidden buttons in CRM 3.0 you know that the getElementById method is used to find the Id of the button you want to hide and then you use DHTML to hide the button.

In CRM 4.0 there is some auto-incremented number or randomly generated number that gets placed at the end of all of the ElementId's on a page. Which means that the code used for CRM 3.0 will break.

The solution we found for this is to use the "title" tag, which is linked to the tooltip of your buttons. Here's the code we used to hide a custom button we wrote to map out driving directions to a client:

//Get all of the List Elements
var lis = document.getElementsByTagName('LI');

var i = 0;
//Loop through the list items
while (i < lis.length) {
//Don't worry about any list item that doesn't have the title you are looking for.
if (lis[i].getAttribute('title') == 'View directions to this account.')
{
//Replace the DHTML with blank tags to hide the button
lis[i].outerHTML='<SPAN></SPAN>'
}
i = i + 1;
}

And you're all set. Happy scripting!


If you want to hide the "Add Existing" button you can use the following script (posted by Dave Hawes):

HideAssociatedViewButtons('Account_New_Project', ['Add existing Project to this record']);

function HideAssociatedViewButtons(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);
}
}
}

function HideViewButtons(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;
}
}
}
}
}
}
}
