That's okay, It's done..

Here's what I code.
I don't know if I could optimize this..

public class gTemplate : ITemplate
{
   public gTemplate(){}
   public InstantiateIn(System.Web.Ui.Control.container)
   {
       Literal myLnk= new Literal();
       myLnk.DataBinding+=new EventHandler(this.Id_DataBinding);
      container.Controls.Add(myLnk);
   }
   private void Id_DataBinding(Object sender, EventArgs e)
   {
      Literal myLiteral = (myLiteral) sender;
      GridViewRow myRow (GridViewRow) myLiteral.NaminContainer;
       myLiteral="<a href=\"#\" onclick="myFunction('"+
DataBinder.Eval(myRow.DataItem,"Id").ToString()+"')\">Delete</a>";
   }
}

And I add to the gridview

TemplateField myTemplate=newTemplateField();
myTemplate.ItemStyle.Width=100;
myTemplate.ItemTemplate=new gTemplate();
myGridView.Columns.Add(myTemplate);
