Thanks for your followup Tdar,
From the code snippet you provided, I think the problem is caused by the
following line:
Label lbldesc = FormView1.Row.FindControl("heightLabel") as string
Label lbldesc
is the variable declaration style in C#, also there is no "as" in VB.NET.
in VB.NET, we should use
dim lbldesc as Label
lbldesc = FormView1.Row.FindControl("heightLabel")
if you feel necessary, you can also do a explicit cast like:
lbldesc = CType(Label, FormView1.Row.FindControl("heightLabel"))
Hope helps. Thanks,

|
| This is helpfull, however,
|
|
|
| Protected Sub Button1_Click(ByVal sender As Object, ByVal e As
| System.EventArgs) Handles Button1.Click
| Dim output As String
| Label lbldesc = FormView1.Row.FindControl("heightLabel") as string
| output = lbldesc.text
| MsgBox(output)
| End Sub
|
|
| When i use the "label" as the first word it:
| Error 9 'label' is a type and cannot be used as an expression.
|
| If i do :
|
| Dim output As String, lblid
| lblid = FormView1.Row.FindControl("lengthLabel")
| output = lblid.text
| MsgBox(output)
|
| not sure what TYpe it is looking for I try string and i get value of type
| 'system.web.ui.control cannot be converted to string.
| I tried array as thing
