Here is Microsoft Suggestion for this http   msdn microsoft com en-us library bb907626 aspx Y800  On the gridview add a command button and convert it into a template  then give it a commandname in this case  AddToCart  and also add CommandArgument   lt      GridViewRow  Container  RowIndex       lt asp TemplateField gt     lt ItemTemplate gt       lt asp Button ID  AddButton  runat  server         CommandName  AddToCart         CommandArgument   lt      GridViewRow  Container  RowIndex   gt         Text  Add to Cart    gt     lt  ItemTemplate gt    lt  asp TemplateField gt    Then for create on the RowCommand event of the gridview identify when the  AddToCart  command is triggered  and do whatever you want from there  protected void GridView1 RowCommand object sender  GridViewCommandEventArgs e      if  e CommandName     AddToCart              Retrieve the row index stored in the         CommandArgument property      int index   Convert ToInt32 e CommandArgument           Retrieve the row that contains the button         from the Rows collection      GridViewRow row   GridView1 Rows index           Add code here to add the item to the shopping cart            One mistake I was making is that I wanted to add the actions on my template button instead of doing it directly on the RowCommand Event

MSDN says that      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  lt    Container DataItemIndex    when the GridView control has no paging enabled    So you shouldn t need to set it manually  A row command with GridViewCommandEventArgs would then make it accessible  e g   protected void Whatever RowCommand  object sender  GridViewCommandEventArgs e         int rowIndex   Convert ToInt32  e CommandArgument
