Text Box Problem

S

shapper

Hello,

I have a master page where my form has the Runat="server".
The master page as a control place holder, named "cphContent".
Then in a page which inherits from the master page I added a custom
control which I created.
This custom control is added to "cphContent" at runtime.
The custom control creates and adds 2 textboxes using
CreateChildControls.

I am getting an error:
System.Web.HttpException: Control 'ctl00_cphContent_by27cf_tbName' of
type 'TextBox' must be placed inside a form tag with runat=server.

I have no idea why do I get this error.
The form with Runat="server" is in the master page.

Anyway, can someone tell me how can I figure what is going on?

Thanks,
Miguel

Here is my code.

I am adding and creating all controls at runtime in my pages.

------------------------------------------------------------------------

Base.master:

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="fBase" runat="server"></form>
</body>
</html>

Base.master.vb:

Protected Sub Page_Init(ByVal sender As Object, ByVal e As EventArgs)
Handles Me.Init

Dim pContainer As New Panel
AddHandler pContainer.Init, AddressOf pContainer_Init
Me.Controls.Add(pContainer)

Dim cphContent As New ContentPlaceHolder
AddHandler cphContent.Init, AddressOf cphContent_Init
pContent.Controls.Add(cphContent)

End Sub

MyPage.aspx:

<%@ Page Language="VB" CodeFile="Default.aspx.vb" Inherits="_Default"
%>


MyPage.aspx.vb:

Protected Sub Page_Init(ByVal sender As Object, ByVal e As EventArgs)
Handles Me.Init

Dim by27fContactForm As New By27.Web.UI.Form.Contact
AddHandler by27fContactForm.Init, AddressOf by27fContactForm_Init
pContacts.Controls.Add(by27fContactForm)

End Sub



Class Contact in Namespace By27.Web.UI:

Namespace Web.UI.Form

' Content
<DefaultProperty("Text"), ToolboxData("<{0}:ContactForm
runat=server></{0}:ContactForm>")> _
Public Class Contact
Inherits WebControl

Dim by27cf_tbName As New WebControls.TextBox
Private Sub by27cf_tbName_Init(ByVal sender As Object, ByVal e As
System.EventArgs)
With by27cf_tbName
.CssClass = Me.TextBoxCssClass
.ID = "by27cf_tbName"
.Width = Unit.Percentage(100)
End With
End Sub

<Bindable(True), Category("Appearance"), DefaultValue(""),
Localizable(True)> Property TextBoxCssClass() As String
Get
If CStr(ViewState("TextBoxCssClass")) Is Nothing Then
Return String.Empty
Else
Return CStr(ViewState("TextBoxCssClass"))
End If
End Get
Set(ByVal Value As String)
ViewState("TextBoxCssClass") = Value
End Set
End Property

Protected Overrides Sub CreateChildControls()
AddHandler by27cf_tbName.Init, AddressOf by27cf_tbName_Init
MyBase.Controls.Add(by27cf_tbName)
' Create child controls
MyBase.CreateChildControls()
Me.ChildControlsCreated = True
End Sub

End Class

This is a bug of Visual Studio. A problem is that in content page you don't
have form
