  1.   

    大牛们<dx:GridViewDataTextColumn Width="40" HeaderStyle-Wrap="True" VisibleIndex="1" Caption="编辑">
                                        <HeaderStyle HorizontalAlign="Center" />
                                        <CellStyle HorizontalAlign="Center">
                                        </CellStyle>
                                        <DataItemTemplate>
                                            <dx:ASPxButton ID="btnView" runat="server" Text="M" OnInit="btnshow"></dx:ASPxButton>
                                        </DataItemTemplate>
                                    </dx:GridViewDataTextColumn>
    这部分为什么 OnInit="btnshow" OnInit方法才能调用后台 添加CLICK或者<%(后台方法）%> 都不好用？
    还有下面图的属性栏 怎么没有事件呢？
      

  2.   

     KeyFieldName="SalesOrderID" 还有ASPXGRIDVIEW的这个属性为什么要设置？何用？新手求助
