Question

如何从gridview下面的单选按钮列表中访问方法后面的代码？在这里不允许使用代码块。

<asp:GridView ID="gvChildren" runat="server" DataKeyField="ID"> <Columns> <asp:TemplateField> <ItemTemplate> <asp:RadioButtonList runat="server" ID="rblAccess"> <asp:ListItem Value="0" Text="<%= Get("test") %>"></asp:ListItem> <asp:ListItem Value="1" Text="<%= Get("test") %>">dfgdfg</asp:ListItem> <asp:ListItem Value="2" Text="<%= Get("test") %>"></asp:ListItem> </asp:RadioButtonList> </ItemTemplate> </asp:TemplateField> </Columns> </asp:GridView>

我认为这是不可能的（仅在具有DataBinding事件的对象上支持数据绑定表达式）。您可以在代码隐藏中设置Text。例如：

<asp:RadioButtonList runat="server" ID="rblAccess">
<asp:ListItem Value="0" ></asp:ListItem>
<asp:ListItem Value="1" ></asp:ListItem>
<asp:ListItem Value="2" ></asp:ListItem>
</asp:RadioButtonList>

代码隐藏：

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    If Not Page.IsPostBack Then
        Me.rblAccess.DataBind()
    End If
End Sub

Private Sub rblAccess_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles rblAccess.DataBound
    For Each item As ListItem In rblAccess.Items
        item.Text = getAccessText(item.Value)
    Next
End Sub

Private Function getAccessText(ByVal value As String) As String
    Return "text for item " & value
End Function
