Question

我需要将title绑定到数据源，以便显示的网页标题取决于数据源中的数据。

当我使用Formview和hiddenfield从数据源获取数据代码无法编译时

如何根据数据源中的数据创建可以显示pagetitle的脚本？

<Script runat = "server">
 Protected sub Page_load(Byval sender as Object, Byval e As System.eventargs)
     Title = Hiddenfield1.value
 End sub
</Script>

<asp:FormView ID="FormView2" runat="server" DataSourceID="SqlDataSource1">

<ItemTemplate>

<asp:HiddenField ID="HiddenField1" runat="server" Value= '<%#eval ("PageTitleConstruct") %>' />

</ItemTemplate>
</asp:FormView>

Answer 1

试试这个

  Sub FormView2_ItemCreated(ByVal sender As Object, ByVal e As EventArgs)

    Dim HiddenField1 As HiddenField = CType(FormView2.FindControl("HiddenField1"), HiddenField)

    Page.Title = HiddenField1.Value;

  End Sub

Answer 2

在Page_Load函数中。你必须比你更早得到这个值。

 Page.Title = value here.

Answer 3

您应该能够收听ItemCreated事件，并在该回调中设置标题。

Answer 4

我已尝试过该脚本，但在使用

时

FormView2_ItemCreated(ByVal sender As Object, ByVal e As EventArgs)
    Dim HiddenField1 As HiddenField = CType(FormView2.FindControl("HiddenField1"), HiddenField)

    Page.Title = HiddenField1.Value;

End Sub

page.title值只有

但如果我将事件更改为

，请更正

Private Sub FormView2_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles FormView2.Load
        Dim hiddenfield1 As HiddenField = CType(FormView2.FindControl("hiddenfield1"), HiddenField)     
        Page.Title = hiddenfield1.Value
  End Sub
