Devexpress 中 aspxGridView GridViewDataHyperLinkColumn Eval绑定连接参数的问题

                      <dxwgv:ASPxGridView ID="GridDiscard" Width="95%" runat="server" AutoGenerateColumns="False">
                <Columns>
                    <dxwgv:GridViewDataTextColumn Caption="申请部门" FieldName="APPLY_DEPARTMENT" VisibleIndex="0">
                    </dxwgv:GridViewDataTextColumn>
                    <dxwgv:GridViewDataTextColumn Caption="申请日期" FieldName="APPLY_DATE" VisibleIndex="1">
                    </dxwgv:GridViewDataTextColumn>
                    <dxwgv:GridViewDataTextColumn Caption="设备编号" FieldName="EQUIPMENT_CODE" VisibleIndex="2">
                    </dxwgv:GridViewDataTextColumn>
                    <dxwgv:GridViewDataHyperLinkColumn Caption="设备名称" FieldName="EQUIPMENT_NAME" VisibleIndex="3">
                        <PropertiesHyperLinkEdit NavigateUrlFormatString='DiscardApplyDetail.aspx?BillCode=<%# Eval("Bill_Code")%>'>
                        </PropertiesHyperLinkEdit>
                       
                    </dxwgv:GridViewDataHyperLinkColumn>
                    <dxwgv:GridViewDataTextColumn Caption=" 资产原值" FieldName="OLD_VALUE" VisibleIndex="4">
                    </dxwgv:GridViewDataTextColumn>
                    <dxwgv:GridViewDataTextColumn Caption="资产近值" FieldName="LATEST_VALUE" VisibleIndex="5">
                    </dxwgv:GridViewDataTextColumn>
                    <dxwgv:GridViewDataHyperLinkColumn Caption="操作" VisibleIndex="6">
                       
                    </dxwgv:GridViewDataHyperLinkColumn>
                </Columns>
            </dxwgv:ASPxGridView>本人在设备名称处绑定老是无法显示绑定数据
代码如下
<dxwgv:GridViewDataHyperLinkColumn Caption="设备名称" FieldName="EQUIPMENT_NAME" VisibleIndex="3">
                        <PropertiesHyperLinkEdit NavigateUrlFormatString='DiscardApplyDetail.aspx?BillCode=<%# Eval("Bill_Code")%>'>
