如何使AspNetPager的宽度固定

Question

页面设计代码如下，AspNetPager宽度定为280px，但运行时，依次点击第2、3、4、5页时，AspNetPager的宽度总是有变化，而不是固定不变。现在我要AspNetPager的宽度不变，如何设计？<asp:UpdatePanel ID="resultPanel" runat="server" UpdateMode="Conditional">
                <ContentTemplate> 
                    <webdiyer:aspnetpager id="netPager"  runat="server" horizontalalign="Center" PagingButtonSpacing="8px" 
                        onpagechanged="netPager_PageChanged" ShowPageIndexBox="Always" SubmitButtonImageUrl="image/go.jpg" 
                        ShowCustomInfoSection="Left" CustomInfoHTML="共%PageCount%页 %RecordCount%条记录"
                        SubmitButtonStyle="width:32px;height:22px;vertical-align:bottom" CustomInfoTextAlign="Left" 
                        urlpaging="false" width="280px" LayoutType="Table" 
                        ShowNavigationToolTip="true" UrlPageIndexName="pageindex" PageSize="12" ></webdiyer:aspnetpager>
                    <br />
                </ContentTemplate>
            </asp:UpdatePanel></div>
