Nikifor,

Thank you for your reply. I have seen the examples that you suggested and still don’t get how to create the TemplatedDataField for each columns on the child band when it’s dynamically loaded and the columns of the data source are dynamically created as well.

But, I was able to create the TemplatedDataField but not sure if it’s the correct way. I added an InitializeRow event to the ContainerGrid in the RowIsIandsPopulating event and then in the InitializeRow event I created a new Template and assigned it to the e.Row.Items Template. The buttons show on the child band for each column but I cannot click on any of them. They are acting as if they were ReadOnly.

void whdg1_RowIslandsPopulating(object sender, ContainerRowCancelEventArgs e)

    {

        e.Cancel = true; 

        Supplier sp = (((Infragistics.Web.UI.Framework.Data.ListNode)e.Row.DataItem)).Item as Supplier;

        sp.Products = new List<Products>(NWindClient.GetProducts(Convert.ToInt32(sp.SupplierID))); 

        ContainerGrid child = new ContainerGrid(); 

        child.Enabled = true;

        child.Level = 1;

        child.InitializeRow += new InitializeRowEventHandler(child_InitializeRow); 

        e.Row.RowIslands.Add(child);

        child.DataSource = sp.Products; 

    }

    void child_InitializeRow(object sender, RowEventArgs e)

    {

        for (int i = 0; i < e.Row.Items.Count; i++)

        {

            e.Row.Items[i].Template = new PlaceHolderTemplate(e.Row.Items[i].Text);

        }

    }

Thanks
