[oscar_nadie]

hi,

i have a question, how can i create a groupcommand dynamically with code in c#?

i have this code but doesn't work:

        ImageCommandColumn.Config commcol = new ImageCommandColumn.Config();
        commcol.Hidden = true;
        commcol.GroupCommands.Add(new GroupImageCommand { CommandName = "Gráfica", Icon = Icon.ChartBar });
        commcol.PrepareCommand.Fn = "prepareCommand";
        commcol.PrepareCommand.Fn = "prepareGroupCommand";
        //commcol.GroupCommands.Add(new CommandFill { });
        grd1.ColumnModel.Columns.Add(new ImageCommandColumn(commcol));

please help me!
pardonme for the english, i know that is bad.

thanks

i found the way to do this, and show you how i did.

private GridPanel crearGridPanel() {

        string conn = @"Data Source=OSCAR\SQLEXPRESS; Initial Catalog = Banco; Integrated Security=true";
        SqlConnection objconn = new SqlConnection(conn);
        objconn.Open();
        string strconsulta = "SELECT [cl_cedula],[cl_nombre],[cl_edad],[cl_ingresosmes],[cl_tipo] FROM [CLIENTE]";
        SqlCommand objcomm = new SqlCommand(strconsulta, objconn);
        SqlDataReader objreader = objcomm.ExecuteReader();

        GridPanel grd1 = new GridPanel
        {
            ID = "grd1",
            Border = false,
            StripeRows = true,
            TrackMouseOver = true,
            AutoExpandColumn = "cl_cedula",
            Width = Unit.Parse("700"),
            Height = Unit.Parse("330"),
            Collapsible = true
        };
        grd1.Store.Add(crearStore(objreader));
        grd1.SelectionModel.Add(new RowSelectionModel { SingleSelect = true });
        crearColumn(objreader, grd1);
        grd1.View.Add(new GroupingView{ForceFit = true, MarkDirty = false, ShowGroupName = false,
                      HideGroupedColumn = true, StartCollapsed = true
        });
        objconn.Close();
        return grd1;
    }

    private void crearColumn(SqlDataReader objreader, GridPanel grd1)
    {
        for (int x = 0; x < objreader.FieldCount; x++)
        {
            Column.Config col = new Column.Config();
            col.ColumnID = objreader.GetName(x).ToString();
            col.Header = objreader.GetName(x).ToString().Substring(3);
            col.DataIndex = objreader.GetName(x).ToString();
            grd1.ColumnModel.Columns.Add(new Column(col));
        }
        CommandColumn commcol = new CommandColumn();
        commcol.Hidden = true;
        GridCommand grdcomm = new GridCommand();
        grdcomm.CommandName = "SelectGroup";
        grdcomm.Icon = Icon.TableRow;
        grdcomm.Text = "Grafica";
        CommandFill comf = new CommandFill();
        commcol.Commands.Add(comf);
        commcol.GroupCommands.Add(grdcomm);
        grd1.ColumnModel.Columns.Add( commcol);
    }

    private Store crearStore(SqlDataReader objreader)
    {
        Store store = new Store { ID = "store1", GroupField = "cl_tipo" };
        JsonReader reader = new JsonReader();
        reader.IDProperty = "ID";
        for (int z = 0; z < objreader.FieldCount; z++) {
            reader.Fields.Add(objreader.GetName(z).ToString());
        }
        store.Reader.Add(reader);
        store.DataSource = objreader;
        store.DataBind();
        store.Render();
        return store;
    }

i hope this code help someone.

Suerte!
