Knockout

Knockout Click Binding:

<td>
<a data-bind="text:title,click:$parent.openRecord"/>
</td>

if you use href in "a" tag, the function wont be called.

Inside your view model,

var self = this;
self.openRecord = function (record) { // Write your code here for click operation };


Knockout Dirty flag:


Create new ko object :
ko.dirtyFlag = function (root, isInitiallyDirty) { var result = function () { }, _initialState = ko.observable(ko.toJSON(root)), _isInitiallyDirty = ko.observable(isInitiallyDirty); result.isDirty = ko.computed(function () { return _isInitiallyDirty() || _initialState() !== ko.toJSON(root); }); result.reset = function () { _initialState(ko.toJSON(root)); _isInitiallyDirty(false); }; return result; };


In your view model, you can use the flag like this:
var isDirty = false; //set to true to load your item as Dirty.
  self.dirtyFlag = new ko.dirtyFlag(this, isDirty);

To check for a specific item in your Model as dirty or not,
        self.quantitydirtyFlag = new ko.dirtyFlag(self.quantity, isDirty);

        self.dirtyItems = ko.computed(function () {
        self.isDirty = ko.computed(function () {

            return ko.utils.arrayFilter(self.items(), function (item) {

                return item.dirtyFlag.isDirty();

            });

        }, self);

            return self.dirtyItems().length > 0;

        }, self);

you can check for whether the item is dirty or not by,

record.dirtyFlag.isDirty()
for the specific item,
record.quantitydirtyFlag.isDirty()

Parse Json Date to Date Object

Parse jsondate in JavaScript to a Date Object:
Below are two methods I use  
Method 1:
var jsonDate = "/Date(1224043200000)/"
var value = new Date(parseInt(jsonDate.substr(6)));


Method 2:
var jsonDate = "/Date(1224043200000)/"
var value = new Date(parseInt(jsonDate.replace(/(^.*\()|([+-].*$)/g, '')));

if you want in "mm/dd/yyyy" format, use this along with the above script
var dat = value.getMonth()+ 1 + "/" + value.getDate()+ "/" +value.getFullYear();

Site works in chrome but not in IE/Unable to browse CRM in IE

For a long time, i had trouble browsing my CRM running in Hyper-V in my machine's IE. But it works fine with Chrome/firefox. Then i tried this:

IE is using Kerberos and not falling back on NTLM like Chrome and Firefox. You must force NTLM authentication in IIS7.5 by following these steps: 1. Select your site. 2. Double click authentication. 3. Select "Windows Authentication" (ensuring that it is enabled). 4. Click "Providers..." in the right hand column. 5. Select NTLM and click "Move Up".

Unable to see any forms or grids in CRM

If a user  is unable to see the forms or grids even with proper privilege to the entity, then you probably need to set another privilege as below:

Open the security role. 

Under Customizations tab--> Select Read Privilege for System Form.

System dashboard throws error. ConfigSettings Modify CRM.

Sometimes, I've faced scenarios where even clicking on Dashboards, threw CRM error. especially, when the VM is cloned.

In such cases, the solution was to verify HelpServerUrl in the config settings and modify the same. 

select * from configsettings
---HelpServerUrl value would be' http://<originalservername>'


update ConfigSettings
set Helpserverurl ='http://<servername>/'
where Id='43E2CF02-D524-4E0E-955-6211701D462D'

Business Rules not firing CRM2013

Recently,  i was facing a bizarre issue of Business Rules not firing for Customer Records even though the rule was active for the entity. This was because one of the fields being validated, was not present on the form. Once i added that, the business rule started working again :)

Create Feeds for Custom Entities

Many a times we will come across the scenario where in the clientwould like to see the feeds for custom entities.

Unfortunately, MS prevents us from creating an Activity Feed rule for custom entities. So we cannot configure this directly.

But, there is a perfectly safe workaround for this.

1.       Create a Workflow. i.e. if you want the feeds for creation of a custom entity then create a workflow to fire on create of the record.

2.       The workflow should create a post. Set the attributes as desired.

 

That is all there is to creating a post for a custom entity :)
