Hi I'm using this code and its giving me an error: entity id must be specified for update,

Any help?

private void button3_Click(object sender, EventArgs e)
{
// Update the fetched record
Entity new_Child = new Entity("new_child");

//new_Child.Attributes["new_fullname"] = "joy";

new_Child.Attributes["new_age"] = 6; 

new_Child.Attributes["new_weight"] = (decimal)15; //

new_Child.Attributes["new_height"] = (double)25;


_service = GetService();


Guid g = _service.Create(new_Child);


var cols = new ColumnSet(new[] { "new_age", "new_weight", "new_height" });

_service.Update(new_Child);


}

    It worked, but I wasn't clicking on the create button when I build and start running the code.

    Thank you for replying and your time..

    I used this line columnSet to verify what are the fields that I need to update

    Yes, Only one argument, which is newChild. But in the newChild you need to have Id to identify the correct record.

    After you create the record you have the UniqueIdentifier of the record which is "g".

    You can update teh record like this;

    new_Child.Attributes["new_age"] = 10;

    new_Child.Attributes["id"] = g;

    _service.Update(new_Child);

    hi,

    you need to add id to new_child object

    like:

    new_Child.Id= g;

    _service.Update(new_Child);

    Can you explain this line why are using this:

    var cols = new ColumnSet(new[] { "new_age", "new_weight", "new_height" });

    Yes ..Update takes one argument and in your case ,it is new_Child,but new_Child should contain id attribute.

    Like var new_Child = new Entity("LogicalName");

    new_Child.Id = "Guid of record",

    new_Child["dsadsd"] = "dsadff" ; etc

    and then _service.Update(new_Child); but new_Child.Id = "Guid of record" is most.

    But update I can't put inside the parameter of update more than 1 arg.

    you mean to change this line:

    _service.Update(new_Child);

    into:

    _service.Update(new_Child,g,cols); ??

    if yes, its not working !! I don't know if I get you right. Thanks for your time and your answer

    When you are Updating any record, you need to specify the UniqueIdentifier. Otherwise how does CRM (or any other system) know the record that you are targeting?

    //You get the Service Here;

    _service = GetService();

    //Create the new record using "new_Child" Object.= get the ID to "g"
    Guid g = _service.Create(new_Child);

    //Still "new_Child" has only, "new_age", "new_weight", "new_height"

    // You get col object but never using
    var cols = new ColumnSet(new[] { "new_age", "new_weight", "new_height" });

    // You update the the same "new_Child" object with no Id. It has only "new_age", "new_weight", "new_height".

    _service.Update(new_Child);

    // You should add the "Id" to "new_Child" object with the value in "g". And then update.
