Counting Total number of records retrived by Fetch Xml using Custom workflow


We have done a custom workflow by using fetchxml to get the count of total opened tasks in CRM instance.

Script: 
protected override void Execute(CodeActivityContext context)
{
ITracingService tracingService = context.GetExtension<ITracingService>();
IWorkflowContext workflowContext = context.GetExtension<IWorkflowContext>();
IOrganizationServiceFactory serviceFactory =       context.GetExtension<IOrganizationServiceFactory>();
IOrganizationService service = serviceFactory.CreateOrganizationService(workflowContext.UserId);

String query = @"<fetch version='1.0' mapping='logical' distinct='false' >
<entity name='task'>
<attribute name='subject' />
<attribute name='createdby' alias='countAlias' />
<order attribute='subject' descending='false' />
<filter type='and'>
<condition attribute='statecode' operator='eq' value='0' />
</filter>
</entity>
</fetch>";

FetchExpression fetch = new FetchExpression(query);
EntityCollection results = service.RetrieveMultiple(fetch);
int count = results.Entities.Count; //show this in your message box;
this.count.Set(context, count);

var countname = ((AliasedValue)count.["createdby"]).Value;
systemuser.Set(context, countname);
}
       [Output("Count")]
public OutArgument<int> count { get; set; }

}

}





JavaScript in OData portals

We have done odata services in CRM Portals to achieve through java script.


Step 1: Enable the portal entity list(Contact,Account,etc)
Go to Portal > Entity List. Create a new Entity List for Case Entity.

Step2: Enable Odata feed with entity type and views also in entity list


Step3: Now, To retrieve the data, Hit the URL in browser.
URL : Portal_URL/_odata  
      URL : Portal_URL/_odata/Entity_Set_Name : To retrieve the data
Here we can see the <atom:title type=”text”>Cases</atom:title>

Step4: Upload your JavaScript in your respective “entity form”.
Below script :
if (window.jQuery) {
   (function ($) {
      $(document).ready(function () {
         if (typeof (Page_Validators) == 'undefined') return;
         // Create new validator
         var newValidator = document.createElement('span');
         newValidator.style.display = "none";
         newValidator.id = "titleValidator";
         newValidator.controltovalidate = "title";
         newValidator.errormessage = "<a href='#title_label'>This Case has been already generated.</a>";
         newValidator.validationGroup = ""; // Set this if you have set ValidationGroup on the form
         newValidator.initialvalue = "";
         newValidator.evaluationfunction = function () {
       var count =   GetCase();
               if (count > 0 )
              return false;   // Return false mean apply validation.
             else
              return true;   // Return true mean successful.        
         };
         // Add the new validator to the page validators array:
         Page_Validators.push(newValidator);
         // Wire-up the click event handler of the validation summary link
         $("a[href='#title_label']").on("click", function () { scrollToAndFocus('title_label','title'); });
      });
   }(window.jQuery));
}
function GetCase(){
  var count = 0;
  var title=$("#title").val();
$.ajax({
    type: "GET",
    contentType: "application/json; charset=utf-8",
    datatype: "json",
    url: "~/_odata/Cases?$filter=title eq '"+title+"'",
    beforeSend: function(XMLHttpRequest) {
        XMLHttpRequest.setRequestHeader("Accept", "application/json");
    },
    async: false,
    success: function(data, textStatus, xhr) {
     count = data.value.length;       
    },
    error: function(xhr, textStatus, errorThrown) {
        Xrm.Utility.alertDialog(textStatus + " " + errorThrown);
    }
});
return count;
}


Step5: If duplicate case is created then it will show you like “This Case has been already generated.” Please refer to below screenshot.


To get the Dialog Popup box through html on entity form in Dynamics 365 CRM

We have requirement in Dynamics CRM to get dialog popup box through html.
To get the html

<html><head>
<title> Account Type</title>
<script src="ClientGlobalContext.js.aspx"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script language="javascript" type="text/javascript">
//To get parent form data on popup write logic
function GetAllAccountsRecords()
{
//custom logic
}
function btnSubmit()
{
           //on submit button perform action
  var crmWindow = parent.Alert.getCrmWindow();
     
          //write here to perform action on submit button

parent.$("#alertJs-wrapper").hide();
}

</script>
</head><body onload="GetAllAccountsRecords()">
<br><p>Please, select data.</p><br>
 <br>
<input onclick="btnSubmit();" value="Submit" style="height: 24px;font-family: Segoe UI,Tahoma,Arial;border: 1px solid #C6C6C6;   background-image: none;margin-top: 10px; width: auto !important; min-width: 80px;white-space: nowrap; color: #444444; background-color: #FFFFFF" type="Button">
</body>
</html>

To get lookup details through Plugin in Dynamics Crm

We did a plugin to get lookup reference and set the data in current form. Plugin on post operation,
Update method.

        // Obtain the target entity from the input parameters.
Entity entity = (Entity)context.InputParameters["Target"];
try
{
// Refer to the lead entity .
if (entity.LogicalName == "lead")
{
if (entity.Attributes.Contains("parentcontactid"))

//to get data of lookup we used entityrefernce
var currency = ((EntityReference)(entity.Attributes["parentcontactid"]));
var actualCurrency = service.Retrieve(currency.LogicalName, currency.Id, new ColumnSet(true));
var currencyName = actualCurrency["firstname"].ToString();
var last = actualCurrency["lastname"].ToString();
//throw new InvalidPluginExecutionException("The contact123" + last);
entity.Attributes["firstname"] = currencyName;
//throw new InvalidPluginExecutionException("The contact" + entity["firstname"]);
entity.Attributes["lastname"] = last;
}
}
// Obtain the organization service reference.
service.Update(entity);
}
catch (FaultException<OrganizationServiceFault> ex)
    {
throw new InvalidPluginExecutionException("Howdy! error occurred" +ex.Message);
}
}

To get more than 50 records through ODATA Services

In Dynamics CRM, There is a page limit of 50 records through Odata services. To increase that we should use paging to get more than 50+ records.

//To get account records through Odata services

relatedAccounts = [];

function GetAllAccountsRecords() {
debugger;
    var serverUrl = Xrm.Page.context.getClientUrl();
    var oDataUri = serverUrl + "/xrmservices/2011/OrganizationData.svc/AccountSet?$select=AccountId,Name";
    GetRecords(oDataUri);
    var totalRecords = relatedAccounts.length;
   //alert("Total records :" +totalRecords);


}
 //Calling Odata
function GetRecords(url) {
    $.ajax({
        type: "GET",
        contentType: "application/json; charset=utf-8",
        datatype: "json",
        url: url,
        async: false,
        beforeSend: function (XMLHttpRequest) {
            XMLHttpRequest.setRequestHeader("Accept", "application/json");
        },
        success: function (data, textStatus, XmlHttpRequest) {
            if (data && data.d != null && data.d.results != null) {
                AddRecordsToArray(data.d.results);
                FetchRecordsCallBack(data.d);
}
        },
        error: function (XmlHttpRequest, textStatus, errorThrown) {
            alert("Error :  has occured during retrieval of the records ");
        }
    });
}
//To get more records through Odata services
function AddRecordsToArray(records) {
    for (var i = 0; i < records.length; i++) {
        relatedAccounts.push(records[i]);
  }
}
//To get next page records through Odata services
function FetchRecordsCallBack(records) {
    if (records._next != null) {
        var url = records._next;
        GetRecords(url);
    }
}
//end of Odata services
