public class TemplateGenerator : ITemplate // Class inheriting ITemplate
    {
        ListItemType type;
        string columnName;    
        public TemplateGenerator(ListItemType t, string cN)
        {           
           type = t;    
           columnName= cN;    
        }
        // Override InstantiateIn() method
        void ITemplate.InstantiateIn(System.Web.UI.Control container)
        {    
            switch (type)
            {
                case ListItemType.Item:    
                   HyperLink hyprLnk = new HyperLink();
                   hyprLnk.Target = "_blank"; //Optional.
                   hyprLnk.DataBinding+=new EventHandler(hyprLnk_DataBinding);
                   container.Controls.Add(hyprLnk);
                break;      
            }
        }    
 // The DataBinding event of your controls
 void hyprLnk_DataBinding(object sender, EventArgs e)
      {    
        HyperLink hyprlnk = (HyperLink)sender;
        GridViewRow container = (GridViewRow)hyprlnk.NamingContainer;
        object bindValue = DataBinder.Eval(container.DataItem,columnName);
      // Adding check in case Column allows null values
        if (bindValue != DBNull.Value) 
        {
            hyprlnk.Text = bindValue.ToString();
            hyprlnk.NavigateUrl = "http://www.google.com";
        }
     }

protected void GenerateGridViewColumnsDynamically()
        {
            // Create the TemplateField 
            TemplateField firstName = new TemplateField();
            firstName.HeaderText = "First_Name"; 
            firstName.ItemTemplate = new TemplateGenerator(ListItemType.Item,
                                                          "FirstName");
            // Showing boundField example just for more context
            BoundField lastName = new BoundField();
            lastName.DataField = "LastName";
            lastName.HeaderText = "Last_Name";
           // Add the Columns now
            MyGridView.Columns.Add(firstName);
            MyGridView.Columns.Add(lastName);
        }
