Question

使用SQL Server，我创建了一个组详细信息表＆amp;事件表。向表中添加事件时，它与特定组关联。

下面，我可以使用转发器显示所有组详细信息。但是，我还想显示与每个组相关联的事件。

以下是我的群组详细信息中继器：

<div class="panel-group" id="accordion">
                            <asp:Repeater ID="rptAccordian" runat="server">
                                <ItemTemplate>
                                    <div class="panel panel-default">
                                        <div class="panel-heading">
                                            <h3 class="panel-title">
                                                <a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion" href="#collapse<%= getIndex() %>">
                                                    <%# Eval("Group_Name") %>
                                                </a>
                                            </h3>
                                        </div>
                                        <!-- Get the current index-->
                                        <div id="collapse<%=getIndex()%>" class="panel-collapse collapse">
                                            <div class="panel-body">
                                                <%# Eval("Group_Desc") %>
                                            </div>
                                        </div>
                                    </div>
                                    <!--then increment it for the next repeater element-->
                                    <% incrementIndex(); %>
                                </ItemTemplate>
                            </asp:Repeater>
                        </div>

代码背后：

cmd.CommandText = "select * from Groups News ORDER BY Group_Id DESC";
            cmd.Connection = con;
            con.Open();
            rptAccordian.DataSource = cmd.ExecuteReader();
            rptAccordian.DataBind();
            con.Close();

以下代码显示事件，但不显示每组：

<div class="panel-body" style="height: 400px; overflow-y: scroll;">
                        <asp:Repeater ID="Repeater1" runat="server" OnItemCommand="Repeater1_ItemCommand" EnableViewState="false">
                            <ItemTemplate>
                                <div>

                                    <table class="table table-striped">

                                        <tr>

                                        </tr>

                                        <tr>
                                            <td>Time</td>
                                            <td><%#Eval("Event_Start_Time")  %></td>
                                            <td></td>

                                        <br />
                                    </table>
                                </div>
                            </ItemTemplate>
                        </asp:Repeater>
                    </div>

代码背后：

connR = new SqlConnection(connectionStringR);
    SqlDataAdapter sda = new SqlDataAdapter("SELECT * FROM Events", connR);
    DataTable dt = new DataTable();
    sda.Fill(dt);
    Repeater1.DataSource = dt;
    Repeater1.DataBind();

这是我的桌面结构：

组表：

活动表：

DDL：

CREATE TABLE [dbo].[Group_Events] (
[Id]               INT           IDENTITY (1, 1) NOT NULL,
[Group_Event_ID]   INT           NULL,
[Event_Type]       NVARCHAR (50) NULL,
[Event_Title]      NVARCHAR (50) NULL,
[Event_Cost]       FLOAT (53)    NULL,
[Event_Desc]       NVARCHAR (50) NULL,
[Event_Organiser]  NVARCHAR (50) NULL,
[Event_Date]       DATE          NULL,
[Event_Location]   NVARCHAR (50) NULL,
[Event_Start_Time] DATETIME      NULL,
PRIMARY KEY CLUSTERED ([Id] ASC));

CREATE TABLE [dbo].[Groups] (
[Group_Id]   INT             IDENTITY (1, 1) NOT NULL,
[Group_Name] NVARCHAR (50)   NULL,
[Group_Desc] NVARCHAR (1000) NULL,
PRIMARY KEY CLUSTERED ([Group_Id] ASC));

Group_Id（PK）是Events表中的FK Group_Event_ID。

我不确定如何将我在上面创建的Events表嵌套到我的rptAccordian for Groups中。

我已尝试使用以下代码：

<asp:Repeater ID="rptAccordian" runat="server" OnItemDataBound="Repeater1_ItemDataBound">
                                <ItemTemplate>
                                    <div class="panel panel-default">
                                        <div class="panel-heading">
                                            <h3 class="panel-title">
                                                <a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion" href="#collapse<%= getIndex() %>">
                                                    <%# Eval("Group_Name") %>
                                                </a>
                                            </h3>
                                        </div>
                                        <!-- Get the current index-->
                                        <div id="collapse<%=getIndex()%>" class="panel-collapse collapse">
                                            <div class="panel-body">
                                                <p>
                                                    <%# Eval("Group_Desc") %>
                                                </p>

                                                <table id="tblGroupEvents" class="table table-bordered">
                                                    <tr>
                                                        <th><%# Eval("Event_Title") %></th>
                                                        <td></td>
                                                        <td></td>
                                                    </tr>
                                                </table>
                                            </div>
                                        </div>
                                    </div>
                                    <!--then increment it for the next repeater element-->
                                    <% incrementIndex(); %>
                                </ItemTemplate>
                            </asp:Repeater>

代码背后：

 private void BindRepeater()
{
    string constr = ConfigurationManager.ConnectionStrings["BallinoraDBConnectionString1"].ConnectionString;
    using (SqlConnection con = new SqlConnection(constr))
    {
        using (SqlCommand cmd = new SqlCommand())
        {
            //ORDER BY DATE
            cmd.CommandText = "select * from Groups News ORDER BY Group_Id DESC";
            cmd.Connection = con;
            con.Open();
            rptAccordian.DataSource = cmd.ExecuteReader();
            rptAccordian.DataBind();
            con.Close();
        }
    }
}

protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
    Table table = e.Item.FindControl("tblGroupEvents") as Table;

    string Group_Id = DataBinder.Eval(e.Item.DataItem, "Group_Id").ToString();
    SqlDataAdapter sda = new SqlDataAdapter("SELECT * FROM Group_Events WHERE (Group_Event_ID = '" + Group_Id + "'", con);
    DataTable dt = new DataTable();
     sda.Fill(dt);

    table.DataBind();
}

但是我收到了这个错误：

其他信息：DataBinding：＆＃39; System.Data.Common.DataRecordInternal＆＃39;不包含名称为＆＃39; Event_Title＆＃39;。
的媒体资源

有什么想法吗？
