MS Dynamics CRM - Display Unique/Auto Number on the form before save.

My client requirement is display the unique reg number for new contact before the save record.
My Previous blog <a href="http://makdns.blogspot.com/2016/03/ms-dynamics-crm-generate-uniqueauto.html">MS Dynamics CRM - Generate Unique/Auto Number</a> will show the reg number on form after save the new contact. if the user clicks save and close, they can't see the number.

So i come up with the web service concept to generate unique number for new contact and display on the contact screen.
Also i am using SQL Server sys.sequences for generating new number.

Web Service Code

MS Dynamics CRM - Generate Unique/Auto Number

MS Dynamics CRM doesn't contain auto increment number attribute. My client was assigned each unique registration number for contact entity.
There is lot options available in the market, but i used very easy code to achieve this task. I used pre create plugin operation to create new registration unique/auto number. Number will be create on while saving the record.

i created one custom entity (dns_global), it will keep last reg number.

Dynamics CRM - Update Contact Fullname

My client want the fullname with the suffix and custom order like LastName, FirstName Middle Name Suffix. Dynamics CRM System Settings doesn't have the option to set the custom order fullname. Contact entity fullname is readonly attribute, it won't allow to update the fullname directly.

You can update through only pre create or update operation plugin.

MS Dynamics CRM - Login user's security role using javascript

I have one situation, login user has multiple security roles, if the login user has permission for particular role, show some buttons/fields otherwise the hide buttons/fields.

It is not stright forward to find out the security role, So i wrote one javascript to find out the security role.

Here i am checking the user has "Content Manager" security role or not.

var CMRole = CheckUserRole("Content Manager");
if (CMRole) {
    //true to show buttons
} else {
    //false to hide buttons
}


This function will get all the user's security role Id, passing security role id to get the security role name. If it match, it is true otherwise false.
function CheckUserRole(roleName) {
    var currentUserRoles = Xrm.Page.context.getUserRoles();
    for (var i = 0; i < currentUserRoles.length; i++) {
        var userRoleId = currentUserRoles[i];
         var userRoleName = GetRoleName(userRoleId);
         if (userRoleName == roleName) {
            return true;
         }
    }
    return false;
}


This function calling odata web service and get the each security role name.
 function GetRoleName(userRoleId) {
     var selectQuery = "RoleSet?$top=1&$filter=RoleId eq guid'" + userRoleId + "'&$select=Name";
     var odataSelect = GetServerUrl() + selectQuery;
     //alert(odataSelect);
     var roleName = null;
     $.ajax({
         type: "GET",
         async: false,
         contentType: "application/json; charset=utf-8",
         datatype: "json",
         url: odataSelect,
         beforeSend: function (XMLHttpRequest) { XMLHttpRequest.setRequestHeader("Accept", "application/json"); },
         success: function (data, textStatus, XmlHttpRequest) {
             var result = data.d;
             if (!!result) {
                 roleName = result.results[0].Name;
             }
         },
         error: function (XmlHttpRequest, textStatus, errorThrown) {
             //alert('OData Select Failed: ' + odataSelect);
         }
     });
     return roleName;
 }
