Hi there

 Sorry for the shout in the subject but I have been trying to skin a custom class from a class libarary I feel im just missing a little something.

I have a Solution with a website and a class library (called wem.portal)

In the class library I have a simple custom control with just a label. See bottom of this post for the full code

In the website I call my custom control using the following register and custom tag

At this point all works well (I have not yet created a skin)

The problem is that when I create a skin file using the same register line of code

Compilation Error

Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: BC30002: Type 'WEM.Portal.UI.TestThemeClass' is not defined.

 Line 129:        Private Shared __BuildControl__control64_skinKey As Object = System.Web.UI.PageTheme.CreateSkinKey(GetType(WEM.Portal.UI.TestThemeClass), "blue")

I have managed to get the code working when the code is stored in the App_Code but when I move it to the class library it has this namespace problem

My custom Class:

Option Strict On
Imports System
Imports System.ComponentModel
Imports System.Security.Permissions
Imports System.Web
Imports System.Web.UI
Imports System.Web.UI.WebControls


Namespace UI

< _
            AspNetHostingPermission(SecurityAction.Demand, _
            Level:=AspNetHostingPermissionLevel.Minimal), _
            AspNetHostingPermission(SecurityAction.InheritanceDemand, _
            Level:=AspNetHostingPermissionLevel.Minimal), _
            ToolboxData("<{0}:TestThemeClass> </{0}:TestThemeClass>") _
            > _
Public Class TestThemeClass
    Inherits CompositeControl

    Private LeftLabel As Label



    Protected Overrides Sub CreateChildControls()
        LeftLabel = New Label
        LeftLabel.ID = "lblLeftLabel"
        LeftLabel.Text = "Left List"
        LeftLabel.CssClass = "ijb"

        Me.Controls.Add(LeftLabel)

    End Sub


    Protected Overrides Sub Render(ByVal writer As HtmlTextWriter)

        LeftLabel.RenderControl(writer)
    End Sub



    Protected Overrides Sub RecreateChildControls()
        EnsureChildControls()
    End Sub


End Class

End Namespace

Hey!

 Remove the @Register bit from the top of your page and put this in web.config under system.web / pages / controls:

<controls>

<add namespace="WEM.Portal.UI" tagPrefix="WEMui" assembly="WEM.Portal"/>

</pages>

Basically when you register the control in the page it is only available to that page - doing this makes a global registration which should be recognised by the skin file.

I think i'm posting this 2 years to late for you but it may help someone else ;)
