SharePoint Designer 2013 – Working round some problems

UPDATE: Really Big Hint, if you are in SPDesigner messing with forms then you’re likely doing it wrong. Seriously, Im not kidding, DON’T crack open SPD and mess with DVWP’s look at Display Templates / JS Link every single time. If you have too then this is still a handy article.

Designer is Buggy. So here are some hints when doing DVWP or DFWP including filtering lookups, where to put the cursor + others.

How to get the SiteCollection Url in XSLT

I found this way to get the root site collection url into a DVWP

There are Global parameters available but you have to mess about with the bindings to use them.

 

So for this one you need

<ParameterBinding Name="RootSiteUrl" Location="WPProperty[RootSiteUrl]"/>

 

Then at the top of the XSL (make it global to all templates)

<xsl:param name="RootSiteUrl"></xsl:param>

 

Then in your XSL you can use it

<xsl:value-of select="$RootSiteUrl" />

 

That’s it. Well it worked for me, but SP2013 and designers is so damn flakey it might not work for you, this was done on a WPPage not a wiki page that causes all manner of hell using webpatrs in those things.

Set Fiddlers Icon based on Connected or Not

Thanks to @ericlaw for the info on this, since version 2.4.7.2 of fiddler you can set the Tray Icon to whatever you want.

I like to know at a glance whether fiddler is connected or not, I leave mine running al the time, I have various issues with proxy servers and virtuals, sometimes it’s just easier to manage the hosts file in fiddler perhaps cos I?’m too lazy to go into admin mode and edit the real one.

fiddlerOff fiddlerOn

I used a simple red / green system you can guess which is which 🙂

To do this copy the images to your system somewhere.

Then in Fiddler open the Rules Editor (CTRL-R) and make these changes, just point at your path not mine.

static function OnAttach() {
// MessageBox.Show("Fiddler is now the system proxy");
FiddlerApplication.UI.SetTrayIcon("D:\dev\fiddlerOn.png")
}

static function OnDetach() {
// MessageBox.Show("Fiddler is no longer the system proxy");
FiddlerApplication.UI.SetTrayIcon("D:\dev\fiddlerOff.png")
}

Save it and that’s it.

If they would just give me the option now so a left click on the tray toggles between connected or not and a dbl click open fiddler. Because for me its more than just a debugger now.

Whilst I’m talking changes some more tray options (right mouse menu) that I would love, hope your listening 🙂

  •     Toggle Https decryption
  • Select Gateway option (something I have to do all the time, stupid pac file wont work in fiddler)
  • Autoresponder toggle

God Ted, I love fiddler – or using fiddler to address individual servers on a HNSC)

This tool just gets better for me with every little bit more I learn about it. I use it as a proxy server for my VM’s to keep them of the main network, but have internet access. I use it for speed tests, I use it for dynamic debugging of javascript of sites I have no access too.  It’s wonders do not cease.

Yesterday I had an problem with a Host Named Site Collection, or rather it appears that one of the servers appeared to be slow.  But being a HNSC no AAM’s were created for it and with four front ends to test how the hell do you hit each one sseperately.

Chap running the servers was kind enough to give me the IP addresses and of course I can then edit the hosts file and test each one from the main address.

Well that sucks.

Enter Fiddler, did I say how much I love fiddler ?

In fiddler is a rules file,   CTRL-R will get you there. In that we can do marvelous things, in this case I wanted to handle my HNSC problem by having 4 separate urls I could hit and test each server in a load test script.

My host was something like

http://hnsc.binaryjam.com

and I wanted to hit

http://hnsc1.binaryjam.com

http://hnsc2.binaryjam.com

http://hnsc3.binaryjam.com

http://hnsc4.binaryjam.com

 

Here’s how to do it in fiddler.  Edit the rules file and find the function OnBeforeRequest, its all javascript dontcha know.

Add this bit of code at the bottom of the function

if (oSession.hostname == "hnsc1.binaryjam.com") {
	oSession.hostname = "hnsc.binaryjam.com";
	oSession["x-overrideHost"] = "192.168.1.10"; // <– Server IP here!
}
if (oSession.hostname == "hnsc2.binaryjam.com") {
	oSession.hostname = "hnsc.binaryjam.com";
	oSession["x-overrideHost"] = "192.168.1.11"; // <– Server IP here!
} 
if (oSession.hostname == "hnsc3.binaryjam.com") {
	oSession.hostname = "hnsc.binaryjam.com";
	oSession["x-overrideHost"] = "192.168.1.12"; // <– Server IP here!
} 
if (oSession.hostname == "hnsc4.binaryjam.com") {
	oSession.hostname = "hnsc.binaryjam.com";
	oSession["x-overrideHost"] = "192.168.1.13"; // <– Server IP here!
}

Save it and do a test.

I even ran WireShark to see what was actually happening on the network stack, and it works, it was routing requests for specific servers to each individual server, and because we set the hostname to what it should be any code JS or server using the server name works fine too.

Makes me really want to crack open the fiddler manual and find out what other voodoo I can do.

SharePoint Apps and AngularJS – SP.WebProxy Invocation using promises

Recently I’ve been trying to create a SharePoint 2013 app using AngularJS and angularui-bootstrap.

It’s been going well thanks to Jeremy Thake’s (@jthake) original demo.

But I wanted more! More than just access to the local site, I wanted access to the web, but I wanted to do it in the right AngularJs way, using the service so later when I figure out how to do DI testing I can, using promises too, which of course SharePoint doesn’t return in a way we can use in AngularJS.

So this code snippet (not complete app) will give you a clue on a way of doing it, there may be a better way to do this in AngularJS Im no expert, I see references to module.Factory calls in other examples, but I’m sticking to Jeremy’s starter code for now.

This example uses UK police data, details of the license are here http://www.nationalarchives.gov.uk/doc/open-government-licence/version/2

'use strict';
var myApp = angular.module("myApp", []);

function myAppCtrl($scope, $myDataService) {
	$scope.getPoliceClick = function () {

		//Whoops, edited this line as it was wrong from original post
		var promise = $myDataService.getPolice($scope);
		promise.then(
			//Success callback, check the status = 200 and go mad
			function (response) {
				//...
			},
			//Epic Fail callback
			function (response) {
				//..
			}
		);
	};
};

//this method signature is same as Jeremy"s thats why the $http is there, I use it for lists as well
//just not in this code sample
myApp.service("$myDataService) ", function ($q, $http) {
	this.getPolice = function ($scope) {
		var deferred = $q.defer();
		var context = SP.ClientContext.get_current();
		var request = new SP.WebRequestInfo();
		request.set_url("http://data.police.uk/api/bedfordshire/57");
			request.set_method("GET");
		// We need the response formatted as JSON.
		request.set_headers({
			"Accept": "application/json;odata=verbose"
		});
		var response = SP.WebProxy.invoke(context, request);
		context.executeQueryAsync(
			function () {
				//Notice the scope apply, because the async call is made from outside of angular
				//just resolving will not work
				$scope.$apply(deferred.resolve(response));
			},
			function () {
				$scope.$apply(deferred.reject(response));
			}
		);
		return deferred.promise;
	};
});

Angular Google Maps Example

I’m trying to get my head around angular and using it for writing SharePoint Apps, but one of the first things I wanted to write used google maps.

Luckily (or not depending on how much pain you want to know this caused me) there is a directive library for google maps.

After far too many save and refresh and crash cycles I have a simple example working that has markers and info windows.

Here it is

         </div>
     </div>
     <script>
        var BinaryJamApp = angular.module('BinaryJamApp', ['google-maps']);

        function MappingController($scope) {
			$scope.sites=[];

			$scope.map = {

					panControl: false,
					maxZoom: 20,
					minZoom: 3

					latitude: 52,
					longitude: 0

				zoom: 6
			};

			var onMarkerClicked = function (marker) {
				marker.showWindow = true;
				$scope.$apply();
			}; 

			$scope.sites.push({latitude:52, longitude:0, options: { title: "Southerners" } });

SharePoint 2010/2013 Open a Form on the browse tab

This is something I regularly search for and more and more often I’m finding people posting code versions when all I really want is the URL parameter to force it. So luckily I stumbled across SharePoint Den page that posts the following

http://site/List1/Forms/DispForm.aspx/&InitialTabID=Ribbon.Read

 

So cheers chap, the more places this version is shown I hope helps someone else find the way correct for them

SharePoint 2010/13 Getting the Default Disp Page in JSOM

Being pretty new to JSOM, thought I might write this down so I don?t forget again.

JSOM is just quite a bit different to REST or SPServices or just ferreting around the old server API, so it’s going to take some time.  Give me REST any day, but today I find myself altering some one else’s code.

I needed to find the default display page Url

Well it’s pretty simple, but web examples are gathering all list information the code I had was getting a specific list, not sure that they are still not getting all lists, but hey.

Adding the paramter “Include(DefaultDisplayFormUrl)” into the getByTitle function, instructs CSM that you want this bit of info.

 

   

   <script>


 targetList = clientContext.get_web().get_lists().getByTitle("Glossary", "Include(DefaultDisplayFormUrl)");  


</script> 

 

But you can’t access it immediately.

No you have to wait until after the executeQueryAsync only then can you call the function on the targetList variable, so watch those scopes,

   <script>

 
  targetList = clientContext.get_web().get_lists().getByTitle("Glossary", "Include(DefaultDisplayFormUrl)");  
 
  
  clientContext.executeQueryAsync(
      Function.createDelegate(this, function() { alert( targetList.get_defaultDisplayFormUrl();) } ),
      Function.createDelegate(this, function() {alert("failed")})
  );	

</script>

Using jQuery Queue with SPServices

One of the problems I came across the other day is I had several hundred items in a list to process.  To make life easy I use javascript on a web part page to make an app to process the items I wanted to do. 

However when its hundreds, do them all at once and you’re in trouble.  You block the UI thread, you cant update any status values, I dare not think what would happen if you called a couple of hundred async ajax queries all at once, it might just handle them – you can try it if you want 😉

To get round this I thought I’d try to use jQuery queues.  So in this example I have a custom list which I get data from, I’m using promises to get the data but there was no need, I just used some code from the last example.  Once I have the data I inject it onto the screen an lose the original data array (now this is the point where I should use knockout and let the screen adjust to the observed data, but this is a demo).  Then on a click event, a big process this now button, I iterate thru each item on the page, gets its details and add a function to the queue that calls another function (just for being tidy I could embed) which makes a call to SPServices async update, phew.

Then I tell the queue to start executing the functions in it, one at a time.  At the end of each async success, it calls the next function, you might spot the mistake here, what if it doesn’t succeed (well I forgot to code it, but you need to do something with the item and the queue when you do it).

Hint: When calling functions and sub functions, make sure you “var” every variable, I forgot and it only updated the last item.
