Question

我有一个嵌套的gridview，如下所示。我从DAL / BLL层中的存储过程和方法填充gridview。这很好，数据会像我期望的那样返回到嵌套的gridview。

我想做的是将嵌套网格视图中的boundfield（VisitTypeId）作为超链接，因此用户可以点击它并重定向到患者的相关“访问”（换句话说），'其中ID = {0}和VisitTypeId = {0}'）。

我确信这一定是可能的，但无法找到办法。有人可以帮忙吗？

<asp:GridView ID="gvPatients" runat="server" AutoGenerateColumns="False" DataSourceID="odsPatients" OnRowDataBound="gvVisits_RowDataBound"  
    DataKeyNames="ID" AllowPaging="True" CssClass="interactTable" CellPadding="4" 
    AllowSorting="True" meta:resourcekey="gvPersonsResource1">
     <HeaderStyle CssClass="header" />
        <RowStyle CssClass="row"/>
        <Columns>
         <asp:TemplateField Visible="False">
            <ItemTemplate>
            <asp:Label ID="lblID" runat="server" Text='<%# Eval("ID")%>'></asp:Label>
            </ItemTemplate>
        </asp:TemplateField>
        <asp:Boundfield DataField="ID" HeaderText="ID" />
        <asp:Boundfield DataField="Forename" HeaderText="Forename" />
        <asp:Boundfield DataField="Surname" HeaderText="Surname" />
        <asp:Boundfield DataField="DoB" HeaderText="DoB" DataFormatString="{0:dd/MM/yyyy}" />
        <asp:TemplateField HeaderText="Visits">
            <ItemTemplate>
                <asp:GridView ID="gvVisits" runat="server" AutoGenerateColumns="false" BorderWidth="0" ShowHeader="false" >
                    <Columns>
                    <%-- <asp:BoundField DataField="PatientID" Visible="false" /> --%>
                    <asp:BoundField DataField="VisitTypeID" />
                    </Columns>
                </asp:GridView>
            </ItemTemplate>
        </asp:TemplateField>
        <asp:HyperLinkField DataNavigateUrlFields="ID" DataNavigateUrlFormatString="~/AddEditPatient.aspx?ID={0}" HeaderText="Edit" Text="Edit"  />
        </Columns>
    </asp:GridView>

DAL：

Public Shared Function GetVisitType(PatientId As Integer) As DataSet
Using myConnection As New SqlConnection(AppConfiguration.ConnectionString)
        Using myCommand As New SqlCommand("SPGetVisitType", myConnection)
            myCommand.CommandType = CommandType.StoredProcedure
            myCommand.Parameters.AddWithValue("PatientID", PatientId)

            myConnection.Open()
            Dim ds As New DataSet()
            Using myAdapter As New SqlDataAdapter(myCommand)
                myAdapter.Fill(ds)
                Return ds
            End Using
            myConnection.Close()
        End Using
    End Using

End Function

BLL：

Public Shared Function GetVisitType(ByVal PatientId As Integer) As DataSet
Dim ds As DataSet = ScreeningTestDAL.Visit.GetVisitType(PatientId)
Return ds
End Function

代码隐藏：

    Protected Sub gvVisits_RowDataBound(ByVal sender As Object, ByVal e As GridViewRowEventArgs)

    If e.Row.RowType = DataControlRowType.DataRow Then
        Dim gv As GridView = DirectCast(e.Row.FindControl("gvVisits"), GridView)
        Dim PatientId As Integer = Convert.ToInt32(e.Row.Cells(1).Text)
        Dim ds1 As DataSet = ScreeningTestBLL.VisitManager.GetVisitType(PatientId)
        gv.DataSource = ds1
        gv.DataBind()
    End If

End Sub

像HyperLinkField一样在网格中创建绑定字段
