how to read the values of the clicked buttons tow?

I have a grid-view and in one column, I added buttons with every row that it is creating a button. What I need now is, if someone clicks on that button I need to get the field of that corresponding row. I have searched for the solution but i can't find out how to do it ?

<asp:GridView ID="GridView1" runat="server" AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False" DataKeyNames="Id" DataSourceID="SqlDataSource1" OnSelectedIndexChanged="GridView1_SelectedIndexChanged">
                    <Columns>

                        <asp:BoundField DataField="brandname" HeaderText="brandname" SortExpression="brandname" />
                        <asp:BoundField DataField="info" HeaderText="info" SortExpression="info" />

                    </Columns>

protected void gView_RowDataBound(object sender, GridViewRowEventArgs  e)
{
DataRowView rowView= (DataRowView)e.Row.DataItem;


    if (rowView["ColumnId"] != DBNull.Value)
    {
        var val =rowView["ColumnId"];

    }

}

// you can also do like this

void GridView_RowCommand(Object sender, GridViewCommandEventArgs e)
{
   //Check if it's the right CommandName... 
  if(e.CommandName=="Add")
   {
     // do code
   }
}
