With TemplateFields you have to use FindControl on the GridViewRow not the cell:

TextBox txtPin= (TextBox)gr.FindControl("txtPin");

You always have to use FindControl on the NamingContainer of the control you want to find. If the control is in a GridViewRow then that is it's NamingContainer.

You need to use RowDataBound event

if(e.Row.RowType == DataControlRowType.DataRow)
    {
  // find and edit your control here
 // example 
  Label date = (Label)e.Row.FindControl("ControlID");
    }
