合并Templatefield与Boundfield

Question

我有这个行字段，它包含与前一行相同的值。我可以使用boundField合并它，但是当我将它更改为templateField时，代码中的最后一行并不像我想的那样工作。因此，我使用绑定字段(将最后一行更改为边界字段)对其进行了比较，它起了作用。我之所以使用templatefield，是因为我想使用链接按钮commandArgument，这样它就可以使用会话将选定的数据传递到另一个页面。所以我的问题是，为什么合并与模板字段不能很好地结合呢？但是它在束缚场中工作得很好吗？我仍然想使用模板字段，因为链接按钮。但是，如果有人可以给我一个例子来使用绑定字段与链接，我是开放的使用它。

这是我的aspx代码。

<asp:GridView ID="GridViewApproval" AutoGenerateColumns="false" runat="server" CssClass="Grid" AllowPaging="true"       
    Width="100%" OnDataBound="OnDataBound" ShowHeaderWhenEmpty="true" EmptyDataText="No Data Found">

     <Columns>

        <asp:TemplateField HeaderText="No.">
            <ItemTemplate>
                <asp:Label ID="lblNo" runat="server"
                    Text = '<%# Container.DataItemIndex + 1 %>'> </asp:Label>
            </ItemTemplate>
        </asp:TemplateField>

         <asp:BoundField DataField="EMPLOYEE_ID" HeaderText="Emp ID"/>
         <asp:BoundField DataField="EMPLOYEE_NAME" HeaderText="Emp Name"/>
         <asp:BoundField DataField="POSITION_DESCRIPTION" HeaderText="Position"/>
         <asp:BoundField DataField="SECTION_DESCRIPTION" HeaderText="Section"/>
         <asp:BoundField DataField="PROPOSED_TOPIC" HeaderText="Topic"/>
         <asp:BoundField DataField="METHOD_DEV_NAME" HeaderText="Method of Development"/>
         <asp:BoundField DataField="ESTIMATE_COST" HeaderText="Cost Estimation(USD)" />
         <asp:BoundField DataField="ROD_DESC" HeaderText="Reason of Dev"/>
         <asp:BoundField DataField="SCHEDULE_PLAN" HeaderText="Schedule Plan"/>
         <asp:BoundField DataField="ILP_CODE" HeaderText = "CODE" />

         <asp:TemplateField HeaderText="CODE">
            <ItemTemplate>
            <asp:LinkButton ID="linkAction" runat="server"
                CommandArgument = '<%# Eval("ILP_CODE")%>'                   
                Text = '<%# Bind("ILP_CODE")%>' OnClick = "ActionApproval"></asp:LinkButton>
            </ItemTemplate>
        </asp:TemplateField>

         </Columns>

    </asp:GridView>

这是我的aspx.cs代码

                }

        }

        string ilpCode = null, ilpCodeSave = null;

        for (int count = 0; count < GridViewApproval.Rows.Count; count++)

            ilpCode = GridViewApproval.Rows[count].Cells[10].Text;
            if (!ilpCode.Equals(ilpCodeSave))
            {
                //GridViewApproval.Rows[count].Cells[10].Text = "Details";
            }
            ilpCodeSave = GridViewApproval.Rows[count].Cells[10].Text;

        }
    }

    for (int i = GridViewApproval.Rows.Count - 1; i > 0; i--)
