Question

我希望在按下按钮后从代码中获取转发器值。但在我的代码隐藏中，转发器总是来了＃34; 0＆＃34;。我的意思是没有。

我是aspx页面中的转发器：

<asp:Repeater ID="MyRepeater" runat="server" DataSourceID="SqlDataSourceU">
    <HeaderTemplate>
        <table>
            <tr>
                <th>Car Type</th>
                <th>Cars</th>
            </tr>
    </HeaderTemplate>

    <ItemTemplate>
        <tr>
            <td>
                <asp:Label runat="server" ID="lblUnitTypeValue" Text='<%# Eval("CarTypeName") %>' />
            </td>
            <td>
                <th>
                    <asp:DropDownList ID="ddlCars"
                        runat="server"
                        DataSourceID="SqlDataSourceViews"
                        DataTextField="problemLocationName"
                        DataValueField="problemLocationId"
                        Width="212px">
                    </asp:DropDownList>
                    <asp:SqlDataSource ID="SqlDataSourceViews"
                        runat="server"
                        ConnectionString="<%$ ConnectionStrings:MyConnectionString %>"
                        SelectCommand="SELECT [problemLocationId],[problemLocationName] FROM [ProblemLocation]"></asp:SqlDataSource>
                </th>
            </td>
        </tr>
    </ItemTemplate>
    <FooterTemplate>
        </table>
    </FooterTemplate>
</asp:Repeater>

<asp:SqlDataSource
        ConnectionString="<%$ ConnectionStrings:QfsAdminConnectionString %>"
        ID="SqlDataSourceU" runat="server"
        SelectCommand="SELECT [CarTypeName] FROM [CarType]">
</asp:SqlDataSource>

这是我的代码隐藏。它不会进入我的foreach循环，因为它总是没有任何东西。但事实并非如此，我的中继器中有值。所以我想按下按钮并从我的转发器中获取值。

Protected Sub btnSaveDefaultView_Click(sender As Object, e As EventArgs) Handles btnSaveDefaultView.Click
    Dim itens As Repeater = CType(ViewDefaultView.FindControl("RepeaterUnitTypes"), Repeater)

    For Each item In itens.Items

    Next
End Sub

Answer 1

使用此代码从转发器获取值，无需查找转发器：

For Each rItem As RepeaterItem In MyRepeater.Items
  Dim lbl As Label = DirectCast(rItem.FindControl("lblUnitTypeValue"), Label)
  If Not IsNothing(lbl) Then
    Dim value As Integer = Convert.ToInt32(lbl.Text)
  End If
Next

Go Horse Awnser在这里！

将Repeater生成的html解析为JSON'[CarType]'对象，并将其解析为服务器。
