Frank,

This is what I have done for a similar situation. This was advised to me by Kevin a couple of years ago and since it continues to work I haven't changed it. It may been done better using the Entity object but like I said it works for me now:

        this.cboControl.BindingType = mmBindingType.None;
        dsClient.Tables[0].Rows[0]["colName"] = this.cboControl.SelectedValue;

This turns off the binding on the combo box (which you could also do on the properties of the combo box) and sets the value of the column directly into the dataset which was established at the top of the click method. "colName" is the name of the column in your table.

>Thanks. I've got a problem when adding records. My editing works fine, but when I save from an Add, I am getting back a Concurrency violation. I've tracked it down to a combobox on my form that maintains a list of options that are hard code, not pulled from a table, for example: Male or Female.

>In my Save, I was setting the value of the Sex field to the SelectedValue of the combo, but that seems to trigger something in MM.NET to make it think it should run an Update rather than an Insert. So, I think the problem is how to configure the combo so that it uses a hard coded list, but gets bound to the datafield.

>>As far as unbound combos/dropdownlists, I am not sure what you mean. If these controls exist and they are not bound, what is their purpose? If they are bound to the business object then they will be part of the save process.

>>>Hi Bob,

>>>that's pretty much exactly what I have. Can I see the code for saving? Also how do you handle unbound combos/dropdownlists?
