Answer 1

Try this ...

    private void grid()
   {
      if(!string.IsNullOrEmpty(yourSearchTextBox.Text)
      {
      // Then call search method. Make sure you bind the Grid in that method.
      }
      else
      {
      // Normally Bind the Grid as you are already doing in this method.
      }
   }

you have to check whether there is any search Text or not in that grid() method like...
