Have you registered the phones biz object as a child of the client biz object (e.g., oClient.RegisterChildBizObj(oPhones))?
I think that will take care of all that.
If that won't work for your form, then you will just need to refresh your child dataset any time you move to a new client record.

The buttons for the child grid should be separate from the grid, I would think.

To show the drop down list in the grid, you will need to write a little code. Here's what it is for Windows Forms. It should be pretty similar for a web app.

            DataGridViewComboBoxColumn dgvccColName = (DataGridViewComboBoxColumn)grdGridName.Columns["colColumnName"];
            dgvccColName.DataSource = oPhoneType.GetCurrentDataSet().Tables[oPhoneType.TableName];
            dgvccColName.ValueMember = "PhoneTypePK";
            dgvccColName.DisplayMember = "PhoneType";

I hope that helps.

>Hi,

>I am struggling with trying to set up a web form using a GridView to display and edit the many side of the relationship between Clients and Phones. That is, I am editing a Client record and want to display the many phones that the client can have in a grid. My table structure is like this:
>
>Client:
>ClientPK (primary key)
>Name, etc
>
>Phones:
>PhonePK (primary key)
>PhoneTypeFK (foreign key to phone type lookup)
>PhoneNumber
>ClientFK (foreign key to Client)
>
>PhoneTypes:
>PhoneTypePK (primary key)
>PhoneType (description like "Home", "Mobile", "Work", etc)
>
>I have my Client Business Object (oClient) set up and working, along with my Phone Business Object (oPhone) and my PhoneType BO (oPhoneType).
>
>On my grdPhones I have set up columns for the Edit button, the Delete button, the PhoneTypeFK (which I want to be a dropdownlist showing the Phone Type) and the phone number. I also have an Add Phone button elsewhere on the form. It currently displays OK (except that it displays the PhoneTypeFK rather than the Phone Type description).
