在asp.net中的gridview中合并具有相同值的单元格时，无法获得Cell的值

问题描述

This code is to merge cells with equal values in a GridView
but here i ma getting problem while going through this loop
<pre lang="c#"> for (int i =0; i < row.Cells.Count; i++)

                {

if (row.Cells[i].Text == previousRow.Cells[i].Text)

                {

                    row.Cells[i].RowSpan = previousRow.Cells[i].RowSpan < 2 ? 2 :

                                           previousRow.Cells[i].RowSpan + 1;

                    previousRow.Cells[i].Visible = false;

                }

}

自row.Cells [i] .Text以来，所有单元格都适用此条件=和previousRow.Cells [i] .Text =

帮助我获取网格单元格的真实文本值。

这是我的Gridview设计。

This condition is going to be true for all cells since row.Cells[i].Text="" and previousRow.Cells[i].Text=""
so help me to get real Text values of my grid cells.
here is my Gridview design.

<asp:GridView ID="grdOverallAvg" runat="server" AutoGenerateColumns="false" DataKeyNames=""
                   AllowPaging="True" PageSize="10" Width="100%"
                   OnPageIndexChanging="grdSuggestion_PageIndexChanging"
                    önprerender="grdOverallAvg_PreRender">
                   <HeaderStyle HorizontalAlign="Center" CssClass="GridHeaderClass" />
                   <PagerStyle BackColor="#3B5998" ForeColor="White" HorizontalAlign="Center" />
                   <RowStyle HorizontalAlign="Left" CssClass="GridRowClass" />
                   <EditRowStyle BackColor="#999999" />
                   <AlternatingRowStyle CssClass="GridalternetRowClass" ForeColor="#284775" />
                   <FooterStyle CssClass="GridFooterClass" />
                  <Columns>
                       <asp:TemplateField HeaderText="Faculty" ItemStyle-Width="10%">
                           <ItemTemplate>
                               <asp:Label ID="lblfaculty" runat="server" Text='<%# Eval("faculty") %>'></asp:Label>
                           </ItemTemplate>
                       </asp:TemplateField>
                       <asp:TemplateField HeaderText="Time" ItemStyle-Width="15%">
                           <ItemTemplate>
                               <asp:Label ID="lbltime" runat="server" Text='<%# Eval("time") %>'></asp:Label>
                           </ItemTemplate>
                       </asp:TemplateField>
                       <asp:TemplateField HeaderText="Course" ItemStyle-Width="15%">
                           <ItemTemplate>
                               <asp:Label ID="lblcourse" runat="server" Text='<%# Eval("coursename") %>'></asp:Label>
                           </ItemTemplate>
                       </asp:TemplateField>
                       <asp:TemplateField HeaderText="Start Date" ItemStyle-Width="15%">
                           <ItemTemplate>
                               <asp:Label ID="lblStudname" runat="server" Text='<%# Eval("actualstdate") %>'></asp:Label>
                           </ItemTemplate>
                       </asp:TemplateField>
 </Columns>
                </asp:GridView>
