So it seems that you can’t access BCS list data via REST, according to this article. But it seems that you can access the list data through SOAP. I used the code below to query a BCS list that points to a MSCRM 2011 backend (I know I could go right to CRM via REST, but then I would have XSS issues). I then take the results and use them for a jQuery autocomplete for an input box. Obviously in the code below, Contacts is a BCS “external List”

$('#ContactSearchTextbox').autocomplete({
source: function( request, response ) {
	$().SPServices({
	operation: "GetListItems",
	async: false,
	listName: "Contacts",
	CAMLViewFields: "<ViewFields><FieldRef Name='FullName' /><FieldRef Name='ContactId' /><FieldRef Name='ParentCustomerIdName' /></ViewFields>",
	CAMLQuery: "<Query><Where><Contains><FieldRef Name='FullName' /><Value Type='Text'>"+request.term+"</Value></Contains></Where></Query>",
	completefunc: function (xData, Status) {
	$('#SearchResults').html(xData.responseText);
	response($.map( $(xData.responseXML).SPFilterNode("z:row"), function( item ) {
	return {
	label: $(item).attr('ows_FullName') + "(" + $(item).attr('ows_ParentCustomerIdName') +")",
	value: $(item).attr('ows_ContactId')
		}
	}));
	}
	});	    
},
minLength: 4
});

I wanted to have a form that a person would submit (for an example a request of some type) and then it would be approved by the appropriate people. I find the built in workflow functionality too limiting and too difficult for users, so this is what I came up with:

I would have one list that contained fields for both the user to enter data and for each approver to approve or disapprove. In addition, there would be a “Final Approval” field that cold only be set once everyone approved or disapproved and an “I agree” to terms checkbox.

First up, I hid all the fileds on the NewForm.aspx that were related to the approval process. Just the data that was to be collected was shown. I did this with jquery and a CEWP:

<script type="text/javascript">
$(document).ready(function(){
$('tr:has(select[title="User 1"])').not('tr:has(tr)').hide();
$('tr:has(select[title="User 2"])').not('tr:has(tr)').hide();
$('tr:has(select[title="User 3"])').not('tr:has(tr)').hide();
$('tr:has(select[title="User 4"])').not('tr:has(tr)').hide();
$('tr:has(select[title="User 5"])').not('tr:has(tr)').hide();
$('tr:has(select[title="Final Status"])').not('tr:has(tr)').hide();
$('nobr:contains("User 1 Comments")').closest('tr').hide();
$('nobr:contains("User 2 Comments")').closest('tr').hide();
$('nobr:contains("User 3 Comments")').closest('tr').hide();
$('nobr:contains("User 4 Comments")').closest('tr').hide();
$('nobr:contains("User 5 Comments")').closest('tr').hide();
});
</script>

Once this is submitted by the user, and email is sent by a SharePoint workflow (I still don’t like them) telling the approvers to look at the request and approve it (link to the edit page in the email)

Then on the edit page, I used the jquery below to hide the “I agree” so the user could not go back and change it. Also I hid the final approval until all drop downs (Approvals) have changed from “Pending” to Approved or Declined. Obviously there would be security issues, but this is a small use case and we weren’t worried about malicious users (famous last words) – people were on their honor.

<script type="text/javascript">
$(document).ready(function(){
$('tr:has(select[title=IAgree])').not('tr:has(tr)').hide();
$('tr:has(select[title=IAgree])').not('tr:has(tr)').append('<tr><td nowrap="true" valign="top" width="190px" class="ms-formlabel"><H3 class="ms-standardheader">I Agree</H3></TD><td valign="top" class="ms-formbody" width="400px">'+$('select[title=IAgree] :selected').text()+'</td></tr>');

$('select :selected').each(function(){
if($(this).text() == "Pending") {
$('tr:has(select[title=Final Status])').not('tr:has(tr)').hide();
}
});

});
</script

Long title, but I wanted to get across what I was trying to do. If I had and XML file in a document library (you could mail enable the doc lib, and send XML from a query in SQL server using the “FOR XML” statement!), could I use jquery to add Autocomplete values to an input field in a newform.aspx? Ended up being not that difficult.

1. Once the ajax call sucessfully retrievs the xml file, the parseXml routine is called.
2. Seems there is an issue that IE will not think the file is XML, but rather as txt, so there some quick code to load the file as XML
3. Then I just look in the file and grab the values I want, and append them to an array
4. Then just set the array to be used as the autocomplete source

<script type="text/javascript">
$(document).ready(function() {
$.ajax({ 	
	type: "GET",
	url: "http://URL/To/xmlfile.xml",
	dataType: ($.browser.msie) ? "text" : "xml",
	success: parseXml
});
});
function parseXml(data)
{
    var xml;
     if (typeof data == "string") {
       xml = new ActiveXObject("Microsoft.XMLDOM");
       xml.async = false;
       xml.loadXML(data);
     } else {
       xml = data;
     };
 	var results = []; 
	$(xml).find("ID").each(function(){  
		var ClientName = $.trim($(this).find('Name').text());
		var ClientCode = $.trim($(this).find('ZipCode').text());
		results[results.length] = ClientName + "(" + ClientCode + ")"
	});

	$('input[title=Title]').autocomplete({
	source: results,
	delay:10,
	minLength: 3
	});
};
</script>

	

We have a form (list) that we want to have everyone edit and give comments. Once everyone has edited the item, we want an “overall status” field to trigger a workflow (send extended email). Be we did not want the overall status to be changed until everyone has chimed in. To achieve this, we created a list and there was a dropdown with everyone’s name to Approve the item. The default of the dropdown was “Pending”. I used the jquery below to hide the “overall status” until there were no dropdowns that said “Pending”

$('select :selected').each(function(){
if($(this).text() == "Pending") {
$('tr:has(input[title=Overall Status])').not('tr:has(tr)').hide();
};
});

The hide code is code that Paul Galvin published here.
jquery is cool.

Paul Galvin showed how to hide a field in a SharePoint. I wanted to use this code to make a field “read only” once a from has been submitted. Forgetting about DataSheet view (for now), we can put a Content Editor Webpart on the top of the EditFrom.aspx page (to add a CEWP to the top of the edit from, append the URL to this -> EditForm.aspx?ToolPaneView=2) and include his code:

$('tr:has(input[title=Disclaimer])').not('tr:has(tr)').hide();

This will hide the filed based on the Column Name (Disclaimer). Taking this a step further, we can get the selected value (a drop down box in this case), and append a column after the hidden column with some formatting, a column name and the selected value. Effectively making the column readonly.

<script type="text/javascript">
$(document).ready(function(){
$('tr:has(select[title=Disclaimer])').not('tr:has(tr)').hide();
$('tr:has(select[title=Disclaimer])').not('tr:has(tr)').append( '<tr><td nowrap="true" valign="top" width="190px" class="ms-formlabel"><H3 class="ms-standardheader">Disclaimer Accepted:</H3></TD><td valign="top" class="ms-formbody" width="400px">'+$('select[title=Disclaimer] :selected').text()+'</td></tr>');
});
</script>
