    LINQ and QueryExpression will only return attributes that have a value; if an attribute is null, then it won't be included in the Entity record.

    Refer this:

    msdn.microsoft.com/.../microsoft.xrm.sdk.messages.retrieveentityrequest.aspx

    Hi,

    Could you provide some more details what you are doing, how and where you are tying to read field data ??

    to get value from entities field if you have entity object it should be like below

    entity.GetAttributeValue<data type>("field name")

    Please download CRM SDK it has sample code or share full details here so that we can help you.

    Try this

    In java script u can get the value of the field like this

    var a=Xrm.Page.getAttribute("schema name of the field").getValue();

    in c# try this

    entity.GetAttributeValue<String>("schemaname of the field");

    If u find the answer  as useful mark it as verified

    Thanks

                    number = entity.GetAttributeValue<string>("new_number");
                if (entity.Attributes.Contains("new_text"))
                    text = entity.GetAttributeValue<string>("new_text");
                if (entity.Attributes.Contains("new_sms_parameters_smsid"))
                    parameters = entity.GetAttributeValue<string>("new_sms_parameters_smsid");

    Unless you won't tell some details, we won't be able to help you

    "Entity entity = new Entity("new_sms");

                   string number = "";

                   string text = "";

                   string parameters = "";

                   if (entity.Attributes.Contains("new_number"))

                       number = entity.GetAttributeValue<string>("new_number");

                   if (entity.Attributes.Contains("new_text"))

                       text = entity.GetAttributeValue<string>("new_text");

                   if (entity.Attributes.Contains("new_sms_parameters_smsid"))

                       parameters = entity.GetAttributeValue<string>("new_sms_parameters_smsid");

    "

    In order to get field value from the entity object first you need to get it from CRM using CRM service ?? Where are you writing this code ?? what are you trying to do ?? I don't see any code where you retrieve this information from CRM ??
