Modify ItemTempalate to following.Note: i have used CommandArgument to pass selected row_index.

<asp:TemplateField>
    <ItemTemplate>
        <asp:Button ID="btn_add" runat="server" CommandName="Add" CommandArgument="<%# ((GridViewRow) Container).RowIndex %>"
            Text="Add" CssClass="btn btn-align btn-primary" />
        <asp:Button ID="btn_cancel" runat="server" CommandName="Cancel" CommandArgument="<%# ((GridViewRow) Container).RowIndex %>" Text="Delete" CssClass="btn btn-align btn-danger" />
    </ItemTemplate>
</asp:TemplateField>

And add row_command event, and use following server side code , i have handled for "Add" operation only.

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
    if(e.CommandName == "Add")
    {
        // Handling for add
        string arg = e.CommandArgument.ToString();
        int rowidx = int.Parse(arg);
        // arg = selected index, as we are using that in cmd arg.
        GridViewRow SelectedRow = GridView1.Rows[rowidx];
    }
}
