Instead of asp:ButtonField use asp:TemplateField and an asp:Button inside that. Set a CommandName say, MyCommand. Now inside the RowCommand event, do this

var clickedRow = (GridViewRow)((Button)sender).NamingContainer;
var clickedIndex = clickedRow.RowIndex;

You can try with this code - based on CommandArgument

void GridView_RowCommand(Object sender, GridViewCommandEventArgs e)
  {
    if(e.CommandName=="Test")
    {
      int index = Convert.ToInt32(e.CommandArgument);
      GridViewRow row = CustomersGridView.Rows[index];
    }
  }

I've just checked the docs here http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.gridview.rowcommand.aspx

If you look at the "Note" section (below for convenience) you should be able to get the RowIndex from the CommandArguement property:

Note To determine the index of the row that raised the event, use the CommandArgument property of the event argument that is passed to the event. The ButtonField class automatically populates the CommandArgument property with the appropriate index value. For other command buttons, you must manually set the CommandArgument property of the command button. For example, you can set the CommandArgument to <%# Container.DataItemIndex %> when the GridView control has no paging enabled.
