Dynamcis 365 - Override Lookup view using Java script


I have encountered some scenarios  in which I needed to override lookup view columns or apply some filters on the results depending on dynamics conditions at run time on CRM form.

In order to do that , add the following piece of code in the on load event

The following example filters results set no a specific case type


var viewId = "{00000000-0000-0000-0000-000000000001}";

//add the entity name
var entityName = "incident";

// add the view display name
var viewDisplayName = "Problem Cases";

var fetchXml = "<fetch version='1.0' output-format='xml-platform' mapping='logical' distinct='false'>" +
"<entity name='incident'>" +
" <attribute name='title' />" +
"<attribute name='customerid' />" +
"<attribute name='incidentid' />" +
"<order attribute='title' descending='false' />" +
"<filter type='and'>" +
"<condition attribute='bps_type' operator='eq' value='200000005' />" +
" </filter>" +
" </entity>" +

var layoutXml = "<grid name='resultset' object='1' jump='productid' select='1' icon='1' preview='1'>" +
"<row name='result' id='incidentid'>" +
"<cell name='title' width='150' />" +
"<cell name='customerid' width='150' />" +
"</row>" +

Xrm.Page.getControl("parentcaseid").addCustomView(viewId, entityName, viewDisplayName, fetchXml, layoutXml, true);

Quick View Form and sub grid Issue in Dynamics 365


Intro :

I encountered a problem while working with quick view forms having sub grids.

The quick view form is meant to display the account details upon selecting an account on lookup in custom entity form.


Quick view form has sub grid displaying related record to account such as cases and opportunities , the problem occurs whenever you change the select account , all the details are updated to reflect the new selected account except the sub grids .

 They keep displaying the related records to the old one.

Fix :

  1. Add on change event handler on the account lookup
  2. Include the following piece of code in your java script function

var quickViewControl = Xrm.Page.ui.quickForms.get("your quick view form name");
if (quickViewControl != undefined) {
if (quickViewControl.isLoaded()) {

MS CRM - What is the "IsDirty" Method ?


The "IsDirty()" Method returns a Boolean value indicating if there are unsaved changes to  attributes values.


//To Check if the entity is dirty

//To Get Dirty Fields
var attributes = ;
for (var i in attributes)
var attribute = attributes[i];
if (attribute.getIsDirty())
alert("attribute dirty: " + attribute.getName());
