How to add a row to the grid

How to add a row to the grid was created by Orren
In the add row example it shows that there is some id field that is auto generated. How can you add a row in the grid if there is no id field? We get an error saying a particular field must have a value and theData provider is invalid.

How do we add a row for editing?

Thanks!

You can't add row to the grid directly. You have to add row to the DataSet via DataSet.Add; DataSet.Post; sequence. Other way is to get TFireModelAbstract reference from the grid view VIew.GetModel: TFireModelAbstract; and then use this routine:
TFireModelAbstract.InsertRow(Row: Integer; const Parent: TModelIndex): Boolean; //It will invoke the right features in the dataset.

The idea is that we would have a blank row to enter into. If I do :
dataset.append;
the row doesnt appear

If I do
dataset.append;
<fill the row>
dataset.post;

The row does appear - but we do not know at this point what to fill it with.

If I do
dataset.append;
dataset.post;
it violates the field constraints of the dataset - certain fields require data.

How is the component designed to handle new empty rows to be entered?

Thanks!
