вы можете увидеть результат в этом изображении он не отображается должным образом выход и выход я нужен 1 до 10 Нумерация и после этого [...] как это так ответить, как только то, что это решение моего вопроса.

        <asp:DataList ID="dtlpaging" runat="server" RepeatDirection="Horizontal" OnItemDataBound="dtlpaging_ItemDataBound" > 
             <ItemTemplate> 

                 <asp:LinkButton ID="lnkbtnPaging" runat="server" OnClick="lnkbtnPaging_Click" Text='<%# Eval("pagetext") %>' 
                  ValidationGroup='<%# Eval("pageindex") %>' CommandArgument='<%# Eval("pageindex") %>' 
                  CommandName="Paging" CssClass="btn btn-info" style="padding:1px 7px;"></asp:LinkButton> 

             </ItemTemplate> 
            </asp:DataList>
