Hi, Simple question. I'm Using Ver 2.0, Adapter, VB.

My form has some text boxes and is used for entry of new data only, so nothing is fetched on Form load. When the Save button is clicked I need to validate the contents of the Form and if valid Save the data.

But as tableEntity does not yet contain the data sitting in the text boxes, how do I populate the underlying tableEntity, prior to my validation?

Do I do this manually, i.e. for each control or have I missed something

Thanks

Hi Markiemac,

You could auto-fill the tableEntity by databinding or by create the tableEntity at Save button click. Then call adapter.Save(tableEntity) and let the validator do its work, using LLBLGenPro ValidatorClasses.

Hi daelmo,

create the tableEntity at Save button click.

1. Do you mean manually as I would do in:

        Dim tEntity As New TableEntity
        tEntity.RCode = Me.txtRCode.Text
        tEntity.RName = Me.txtRName.Text
        ..etc

As the above could be quite tedious, especially if checking for Null entries, I was interested in any auto methods.

You could auto-fill the tableEntity by databinding

1. As the controls were bound to tableEntity via the BindingSource at design time, I am not clear what you mean here. Could you explain?

Thanks

You may bind a property of a control to a property of the entity as follows:

countryTextBox.DataBindings.Add("Text", _customer, "Country");
