Hi All. I am using a webservice to return a business object which I bind to my webgrid.

Is there a way to use grouping with that business object as the grids datasource?

I have been unable to find documentation on it.

I did see that to sort you have to use a dataview. Is that still true.

I really don't want to create a wrapper to populate a dataset or data table every time I want to sort or group.

Tx,

Roger

Hi,

>Is there a way to use grouping with that business object as the grids datasource?

Grouping is done on the grid level, not the datasource one.
For example:

aspx:
        <c1g:C1WebGrid runat="server" ID="C1WebGrid1" AutoGenerateColumns="false">
            <Columns>
                <c1g:C1BoundColumn DataField="ID" HeaderText="ID">
                    <GroupInfo Position="Header"></GroupInfo>
                </c1g:C1BoundColumn>
                <c1g:C1BoundColumn DataField="NAME" HeaderText="NAME"/>
            </Columns>
        </c1g:C1WebGrid>

cs:
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            LoadData();
        }
    }

    private void LoadData()
    {
        C1WebGrid1.DataSource = GetBO();
        C1WebGrid1.DataBind();
    }

    private object GetBO()
    {
        List<Client> clients = new List<Client>();

        clients.Add(new Client(0, "Client0"));
        clients.Add(new Client(1, "Client1"));
        clients.Add(new Client(2, "Client2"));
        clients.Add(new Client(3, "Client3"));
        clients.Add(new Client(4, "Client4"));

return clients;
}

    public class Client
    {
        private int _id;
        private string _name;

        public Client()
        {
        }

        public Client(int id, string name)
        {
            _id = id;
            _name = name;
        }

        public int ID
        {
            get { return _id; }
            set { _id = value; }
        }

        public string Name
        {
            get { return _name; }
            set { _name = value; }
        }
    }

DataView is used for automatic sorting, if you want to manually sort data, there should not be a problem.
