    Does any one came across this situation or is it possible to find whether any fields are read-only or not from Plugin code??

    I mean field is read-only from JavaScript or form level events. But from Plugin, is there a way to validate fields  in

    (Entity)context.InputParameters["UpdateContent"]  read-only or not??

    Hi,

    The fact that a field is read only or mandatory is managed in the application level. So, if you were to make a field mandatory, it'll prevent you from saving that record from form level, but you can easily save a record having no value on that field using C# code.

    This explains why you cannot get whether a field is read only or not from your Plugin.

    Using metadata surely you can get Requirement level but I don't think you can get if field is readonly or not, because there could be Js code which can make field readonly.

    Hi Mahender,

    Sorry about that! :(

    I mixed read-only with requirement level. :O There's no way to fetch if a field is read-only or not using C#.

    thanks Mahender and Dynamotion for your quick answers and explanation.

    In CRM 4.0, i remember i use to follow below code in Plugin to identify that:-

      var formXmlRequest = new RetrieveFormXmlRequest { EntityName = entityToLookUp.Name };
                var formXmlResponse = (RetrieveFormXmlResponse)crmService.Execute(formXmlRequest);
                var formXml = formXmlResponse.FormXml;               

                var formXmlDocument = new XmlDocument();
                formXmlDocument.LoadXml(formXml);
                var disabledAttributes = formXmlDocument.SelectNodes("//control[@disabled='true']/@id");

                foreach (XmlNode disabledAttribute in disabledAttributes)
                {

                    if (entityToLookUp.Properties.Contains(disabledAttribute.Value))
                    {
                        throw new InvalidPluginExecutionException(disabledAttribute.Value + " field is ReadOnly. Please do not select Any ReadOnly fields while Merge.");
                    }
                }

    Does this give any hint for CRM 2013?? i tried this approach, but it doesn't work. in CRM 2013 the DOM structure is way different. but who knows, there must be a way for it.

    Hi,

    Did some digging around with this thing. The following code should work for you, just tested it. :)

    RetrieveRequest _formRequest= new RetrieveRequest()
{
	ColumnSet = new ColumnSet("formxml"),
	Target = new EntityReference("systemform", new Guid("YOURFORMGUID")) 
};

Entity _systemForm = (Entity)((RetrieveResponse)orgService.Execute(_formRequest)).Entity;

if (_systemForm.Attributes.ContainsKey("formxml"))
{
	XDocument _xDoc = XDocument.Parse(_systemForm.Attributes["formxml"].ToString());
	string _disabled = _xDoc.Descendants("control")
	                   .Single(c => c.Attribute("id").Value == "YOURFIELDNAME")
					   .Attribute("disabled").Value;
}

    Replace YOURFORMGUID with the Form Id from Customizations and YOURFIELDNAME with the fieldname whose enabled status you want to fetch.

    Dynamotion thanks for the update here. 

    I am running this code. I am trying to go through each control and verifying whether it is read only and it is included into UpdateContent or not. 

    but i am getting error on the linq query saying object reference not set to an instance of an object.

    Any idea??

     RetrieveRequest _formRequest = new RetrieveRequest()
                {
                    ColumnSet = new ColumnSet("formxml"),
                    Target = new EntityReference("systemform", new Guid("xxxxxxxx-xxxx-xxxx-xxxxxxxxxxxx"))
                };

                Entity _systemForm = (Entity)((RetrieveResponse)service.Execute(_formRequest)).Entity;

                if (_systemForm.Attributes.ContainsKey("formxml"))
                {
                    foreach (KeyValuePair<String, Object> attr in entityToLookUp.Attributes)
                    {
                        XDocument _xDoc = XDocument.Parse(_systemForm.Attributes["formxml"].ToString());
                        string _disabled = _xDoc.Descendants("control")
                                           .Single(c => c.Attribute("id").Value == attr.Key.ToString())
                                            .Attribute("disabled").Value;
                        trace.Trace("disable attribute : " + _disabled);
                        if (entityToLookUp.Attributes.Contains(_disabled))
                        {
                            throw new InvalidPluginExecutionException(_disabled + " field is ReadOnly. Please do not select Any ReadOnly fields.");

    Yes, Formxml could be your point where you can dig into to search field property, actually I also tried to see formxml first if there is any property that we can use, but I think the only way will be to traverse DOM structure.
