Failed to populate a gridView

Navigation
2

I'm having problems displaying a gridview, it's not displaying the right data, it looks like it's trying to display vertically, I've already changed the Gridline property to horizontal, both and now this Name, same as another gridView I've been running. This my gridview is being populated with information coming from the database. My gridView is this: 

     <asp:GridView ID="gridacao" runat="server" AutoGenerateColumns="False" BackColor="White" BorderColor="#999999" BorderStyle="None" BorderWidth="1px" CellPadding="3" ForeColor="#333333" GridLines="None" ToolTip="Valores Atualizados das ações" Width="344px">
         <AlternatingRowStyle BackColor="Gainsboro" />
         <FooterStyle BackColor="#CCCCCC" ForeColor="Black" />
         <HeaderStyle BackColor="#000084" Font-Bold="True" ForeColor="White" />
         <PagerStyle BackColor="#999999" ForeColor="Black" HorizontalAlign="Center" />
         <RowStyle BackColor="#EEEEEE" ForeColor="Black" />
         <SelectedRowStyle BackColor="#008A8C" Font-Bold="True" ForeColor="White" />
         <SortedAscendingCellStyle BackColor="#F1F1F1" />
         <SortedAscendingHeaderStyle BackColor="#0000A9" />
         <SortedDescendingCellStyle BackColor="#CAC9C9" />
         <SortedDescendingHeaderStyle BackColor="#000065" />
     </asp:GridView>

in part .cs is like this: 

public partial class ExibeAcao : System.Web.UI.Page
{
    string cd;
    protected void Page_Load(object sender, EventArgs e)
    {
        try
        {
            if (!Page.IsPostBack)
            {
                exibirAcao();

            }
        }
        catch (Exception ce1)
        {

            throw new Exception(ce1.Message.ToString());
        }
    }
    private void exibirAcao()
    {
        try
        {
            cd = "PETR4";
            Trataformes tf = new Trataformes();
            this.gridacao = tf.mostraAcao(cd, ref gridacao);
        }
        catch (Exception e2)
        {

            throw new Exception(e2.Message.ToString());
        }
    }
    protected void gridacao_SelectedIndexChanged(object sender, EventArgs e)
    {

    }
}

}

The show () method is this: 

public GridView mostraAcao(string cd, ref GridView gv)
    {
        try
        {
            ManipulaBanco mp = new ManipulaBanco();
            return mp.exibeAcao(cd, ref gv);
        }
        catch (Exception e)
        {

            throw new Exception(e.Message.ToString());
        }
    }

and the method pulls out of the database is this: 

 public GridView exibeAcao(string cod, ref GridView tb)
    {
        try
        {
            bancotccEntities bc = new bancotccEntities();
            var pa = from ac in bc.acao
                     where ac.codigo == cod
                     select new
                     {
                         Ação = ac.codigo,
                         Empresa = ac.empresa,
                         Tipo = ac.tipo,
                         Data = ac.data,
                         Hora = ac.hora,
                         Abertura = ac.abertura,
                         Maxima = ac.maxima,
                         Minima = ac.minima,
                         Média = ac.medio,
                         Valor = ac.fechamento,
                         fechamento_Ontem = ac.f_anterior,
                         Volume_de_Ações = ac.volume,
                         Valor_Negociado = ac.v_financeiro,
                         Variação = ac.variacao,
                         Fase = ac.fase
                     };
            tb.DataSource = pa.ToString();
            tb.DataBind();
            return tb;
        }
        catch (Exception e)
        {

            throw new Exception(e.Message.ToString());
        }
    }

I'm getting the result below:

I would like it to appear horizontally, does anyone know how?

Modify to the following: 

          var pa = from ac in bc.acao
                 where ac.codigo == cod
                 select new
                 {
                     Ação = ac.codigo,
                     Empresa = ac.empresa,
                     Tipo = ac.tipo,
                     Data = ac.data,
                     Hora = ac.hora,
                     Abertura = ac.abertura,
                     Maxima = ac.maxima,
                     Minima = ac.minima,
                     Média = ac.medio,
                     Valor = ac.fechamento,
                     fechamento_Ontem = ac.f_anterior,
                     Volume_de_Ações = ac.volume,
                     Valor_Negociado = ac.v_financeiro,
                     Variação = ac.variacao,
                     Fase = ac.fase
                 };
        tb.DataSource = pa.ToList();
        tb.DataBind();

As the columns did not appear, you may need to implement an automatic column generator for your GridView

1. Declare a class DynamicTemplate 

public class DynamicTemplate : System.Web.UI.ITemplate

2. Declare a constructor where you set the item type 

public DynamicTemplate(System.Web.UI.WebControls.ListItemType type)
{
    templateType = type;
}

3. Create a method in your common class that populates the GridView 

public void AddControl(WebControl wbControl, 
            String BindPropertyName, String BindExpression)
{
    htControls.Add(htControls.Count, wbControl);
    htBindPropertiesNames.Add(htBindPropertiesNames.Count, BindPropertyName);
    htBindExpression.Add(htBindExpression.Count, BindExpression);
}

5. Define another method that sets the container 

public void InstantiateIn(System.Web.UI.Control container)
{
    PlaceHolder ph = new PlaceHolder();
    for (int i = 0; i < htControls.Count; i++)
    {
        //clone control 
        Control cntrl = CloneControl((Control)htControls[i]);
        switch (templateType)
        {
            case ListItemType.Header:
                break;
            case ListItemType.Item:
                ph.Controls.Add(cntrl);
                break;
            case ListItemType.AlternatingItem:
                ph.Controls.Add(cntrl);
                ph.DataBinding += new EventHandler(Item_DataBinding);
                break;
            case ListItemType.Footer:
                break;
        }
    }
    ph.DataBinding += new EventHandler(Item_DataBinding);
    container.Controls.Add(ph);
}

6. Use as follows 

foreach (var propriedade in pa.GetType().GetProperties()) {
    TemplateField t = new TemplateField();
    DynamicTemplate mt = new DynamicTemplate(ListItemType.Item);
    TextBox t1 = new TextBox();
    t1.ID = propriedade.GetName();
    t1.Visible = true;
    t1.Text = propriedade.GetName();
    mt.AddControl(t1, "Text", propriedade.GetName());

    BoundField bf = new BoundField();

    bf.DataField = propriedade.GetName();
    bf.HeaderText = propriedade.GetName();

    tb.Columns.Add(mt);
    tb.Columns.Add(bf);
}
