Hiding Additional Attributes in a list of objects to be binded to a gridview

I have a list of objects of type user site load that has many attributes , i want to hide some of these attributes because i do not want My grid view to show all of these.

How can i do it? I use GridView.DataSource=MyListOfUserSiteLoadObjects;

public partial class Create : System.Web.UI.Page
{
    public List<Entity.UserSiteLoad> MyTempList = new List<Entity.UserSiteLoad>();
    public Entity.UserSiteLoad usl = new Entity.UserSiteLoad();
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            Session["MyApplianceList"] = MyTempList;  
        }


    }

    protected void BtnAddNext_Click(object sender, EventArgs e)
    {
        List<Entity.UserSiteLoad> LstUsl = (List<Entity.UserSiteLoad>)Session["MyApplianceList"];
        usl.Applianc = new Entity.Appliance();
        usl.Applianc.Name = DDLAppName.Text;
        usl.Quantity = Convert.ToInt32(QtyTB.Text);
        usl.DayTime = Convert.ToInt32(DayTymTB.Text);
        usl.BackUpTime = Convert.ToInt32(BackUpTymTB.Text);
        if (LstUsl.Count != 0)
        {
            for (int rowIndex = 0; rowIndex < LstUsl.Count; rowIndex++)
            {
                string AppName = LstUsl[rowIndex].Applianc.Name;
                if (AppName == DDLAppName.Text)
                {
                    LstUsl.Remove(LstUsl[rowIndex]);
                }

            }
        }
        if (LstUsl.Count == 0 || LstUsl.Count > 0)
        {
            LstUsl.Add(usl);
        }



        AllItems.DataSource = LstUsl;
        AllItems.DataBind();
        AllItems.Visible = true;
        Response.Write("It has: " + AllItems.Attributes.Count);


    }
}

2nd problem: I want to add a column to my GridView named "Appliance name" and set its value to usl.Applianc.Name , Applianc is an aggregated object inside user site load object.

How is it possible?

You should configure the AutoGenerateColumns property of the <asp:GridView /> element to false and configure/bind the columns manually.

The following stack will give you an idea of how to do that:

Manually binding data to Gridview

Obviously you should and can bind your own collections to the DataSource property.

I think your code-behind can stay as is and you only have to change some markup:

<asp:GridView ID="AllItems" runat="server" AutoGenerateColumns="false">
    <Columns>
        <asp:BoundField DataField="PropA" HeaderText="Property A" />
        <asp:BoundField DataField="PropB" HeaderText="Property B" />
        <!-- ... -->
    </Columns>
</asp:GridView>
