Question

我正在尝试合并gridview的单元格，这样如果单元格（0）的文本相同，则合并行。问题是我的合并单元格并排显示而不是另一个

请在下面找到我的html和vb代码

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="WebForm1.aspx.vb" Inherits="WebApplication1.WebForm1" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>

    </div>
        <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" OnDataBound="GridView1_DataBound">
            <Columns>
                <asp:BoundField DataField="This" HeaderText="This" />
                <asp:BoundField DataField="Is" HeaderText="Is" />
                <asp:BoundField DataField="A" HeaderText="A" />
                <asp:BoundField DataField="Test" HeaderText="Test" />
            </Columns>
        </asp:GridView>
    </form>
</body>
</html>

Answer 1

您需要做的事实上是删除您正在跨越的单元格。当你给出一个单元格RowSpan = 2时，你所进入的单元格仍在那里 - 它只会被碰到。

GridViewRow.Cells.RemoveAt(index);

合并的gridview行并排显示
