错误 BC30456：“文本”不是“System.Web.UI.Control”的成员

Question

I need to move website from remote server to local IIS (Windows 7 Enterprise). Everything works except some links, error message:

Compiler Error Message: BC30456: 'text' is not a member of 'System.Web.UI.Control'.

Source:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
    Dim data1 = FormView1.FindControl("label18")
    Dim data2 = FormView1.FindControl("label19")
    Dim data3 = FormView1.FindControl("label20")
    Dim data4 = FormView1.FindControl("label21")
    Dim data5 = FormView1.FindControl("label22")
    data1.text = Session("rok")

Last line is highlighted in error message.

When I use "View in Browser" in Visual Web Developer 2008 everything works. What I need to run this site with no errors on IIS?

Answer 1

Convert it to a label then you have access to the Text property.

Dim data1 = TryCast(FormView1.FindControl("label18"), Label)
If Not data1 Is Nothing Then data1.Text = Session("rok")

data1 = Nothing if it does not convert.

Answer 2

Dim data1 = CType(FormView1.FindControl("label18"), Label).text= Session("rok")
