<asp:GridView ID="GV" runat="server" AutoGenerateColumns ="false" >

                        <Columns >
                            <asp:BoundField HeaderText ="ID" DataField ="id"/>
                            <asp:TemplateField HeaderText ="IMAGE">
                                <ItemTemplate>

                                    <asp:Image ID="Img" runat="server" ImageUrl="image" Width="50" Height="50"/> <br />
                                    <asp:Button ID="BtnAdd" runat="server" Text="Add To Cart"  CommandName="add" CommandArgument ='<%#Eval("id") %>' />
                                    <asp:Button ID="btnremove" runat="server" Text="Remove From Cart"   CommandName="remove"  />

                                </ItemTemplate>
                            </asp:TemplateField>

                        </Columns>
                    </asp:GridView>
    </div>

in the business logic i give the storedprocedure name, the sp is

create proc procname
as begin
select id, image from tablename
end

id is id of the image, and image is path of the image. i want to bind all of the images from folder using this path.

protected void Page_Load(object sender, EventArgs e)
    {
        DataSet ds = new DataSet();
        ds = BusinessLogic.DisplayImage();
        GV.DataSource = ds;
        GV.DataBind();

    }
