C# Gridview 居中显示，显示在屏幕中间

只需要加上这段代码：
style="margin: 0px auto;" 

例：
 <cimesui:cimesgridview id="gvshow" runat="server" autogeneratecolumns="false"
                           style="margin: 0px auto;"        allowpaging="true" pagesize="15" oncellcontentclick="gvshow_CellContentClick" onrowcommand="gvshow_RowCommand" onrowediting="gvshow_RowEditing"
                                onrowdatabound="gvshow_RowDataBound">
