GridView、Repeater合并单元格

GridView、Repeater合并单元格

    对于GridView、Repeater生成的表格一般都比较固定，但是有时候我们为了报表统计方便常把列名一样的单元格合并以达到易观察统计的效果，这样我们就需要对控件做必要的合并操作了，具体操作方法如下：

一、           GridView

前台代码：

   一般格式……

后台代码：

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

{

    if (gridInfo.Rows[i].RowType == DataControlRowType.DataRow)

    {

        TableCell tCell = gridInfo.Rows[i].Cells[0];

        TableCell tCell_previous = gridInfo.Rows[i - 1].Cells[0];

        tCell.RowSpan = (tCell.RowSpan == 0) ? 1 : tCell.RowSpan;

 

        tCell_previous.RowSpan = (tCell_previous.RowSpan == 0) ? 1 : tCell_previous.RowSpan;

 

        if (tCell.Text == tCell_previous.Text)

        {

            tCell.Visible = false;

            tCell_previous.RowSpan += tCell.RowSpan;

        }

    }

}

二、Repeater

前台代码：

 

      <asp:Repeater ID="rptAssetUsedPlan" runat="server">
                        <HeaderTemplate>
                            <table style=" 98%; padding-top: 0px;" cellspacing="0px" cellpadding="0px"
                                align="center" class="gridtable">
                                <tr class="thbg" style="padding: 0 0 0 0">
                                    <th align="left" style=" 20%">
                                        系统
                                    </th>
                                    <th align="left" style=" 40%">
                                        设备
                                    </th>
                                    <th align="left" style=" 20%">
                                        计划数量
                                    </th>
                                </tr>
                        </HeaderTemplate>
                        <ItemTemplate>
                            <tr>
                                <td style=" 20%" align="left" runat="server" id="tdAssetparentcategoryname">
                                    <%#Eval("Assetparentcategoryname")%>
                                </td>
                                <td align="left" style=" 40%">
                                    <%#Eval("Assetsubcategoryname")%>
                                </td>
                                <td align="left" style=" 20%">
                                    <asp:TextBox Width="100px" ID="txtPlanCount" runat="server" Text='<%#Eval("AssetCount") %>'></asp:TextBox>
                                </td>
                            </tr>
                        </ItemTemplate>
                        <AlternatingItemTemplate>
                            <tr>
                                <td style=" 20%" align="left" runat="server" id="tdAssetparentcategoryname">
                                    <%#Eval("Assetparentcategoryname")%>
                                </td>
                                <td style=" 40%" align="left">
                                    <%#Eval("Assetsubcategoryname")%>
                                </td>
                                <td align="left" style=" 20%">
                                    <asp:TextBox Width="100px" ID="txtPlanCount" runat="server" Text='<%#Eval("AssetCount") %>'></asp:TextBox>
                                </td>
                            </tr>
                        </AlternatingItemTemplate>
                        <FooterTemplate>
                            </table>
                        </FooterTemplate>
                    </asp:Repeater>

 

后台代码：

数据绑定之后添加如下代码：

  // 合并单元格
            for (int i = rptAssetUsedPlan.Items.Count - 1; i > 0; i--)
            {
                HtmlTableCell oCell_previous = rptAssetUsedPlan.Items[i - 1].FindControl("tdAssetparentcategoryname") as HtmlTableCell;
                HtmlTableCell oCell = rptAssetUsedPlan.Items[i].FindControl("tdAssetparentcategoryname") as HtmlTableCell;

                oCell.RowSpan = (oCell.RowSpan == -1) ? 1 : oCell.RowSpan;
                oCell_previous.RowSpan = (oCell_previous.RowSpan == -1) ? 1 : oCell_previous.RowSpan;

                if (oCell.InnerText == oCell_previous.InnerText)
                {
                    oCell.Visible = false;
                    oCell_previous.RowSpan += oCell.RowSpan;
                }
            }
