Question

我有一个单选按钮列表。加载页面时，我会运行一些脚本和其他内容来确定ID是否通过了测试。所以我想要实际做的是当该页面加载后，在脚本运行后将我的单选按钮设置为失败

以下是清单：

<asp:radiobuttonlist id="rblInspectionStatus" CssClass="descbold"  runat="server" repeatColumns="2" repeatDirection="Horizontal">
       <asp:listitem Value="Pass">Pass</asp:listitem>
       <asp:listitem Value="Fail">Fail</asp:listitem>
</asp:radiobuttonlist>

我试过的是：

rblInspectionStatus.Items.FindByValue("Fail").Selected = True 
rblInspectionStatus.Items.FindByText("Fail").Selected = True
rblInspectionStatus.SelectedIndex |SelectedItem | SelectedValue

我不知道你在Sub或用户Tony Hinkle和用户NoAlias试图说的是正确的尝试，但这是我的假设：

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
            cn.Open() 'Opens the connection
            cmd = New SqlCommand("SELECT PF FROM TABLE WHERE ID = '" & Session("ID") & "'", cn)
            drr = cmd.ExecuteReader
            If drr.Read Then
                rblInspectionStatus.ClearSelection()
                rblInspectionStatus.Items.FindByValue(drr.Items("PF")).Selected = True
            'FIELD PF data either Pass or Fail
            ElseIf Not drr.Read Then
                rblInspectionStatus.ClearSelection()
                rblInspectionStatus.SelectedIndex = -1
            End If
            cn.Close() 'Close the connection
        End Sub

从后面的vb代码设置单选按钮列表
