I have an xsl file that transforms an XML document and outputs it to
my web page.

The xsl file is also creating LinkButtons and they appear on the page.
However, I cannot get the linkbutton click event to fire for these
controls.

My page load event looks like the following:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As
System.EventArgs) Handles Me.Load
        Dim sbrAssemblies As New StringBuilder
        sbrAssemblies.Append("<?xml version='1.0' encoding='utf-8'?>")
        sbrAssemblies.Append("<assemblies>")


        Dim dtAssembly As DataTable =
App_BL.Serialization.GetFullAssembly()

        Dim dr As DataRow

        For Each dr In dtAssembly.Rows
            sbrAssemblies.Append(CStr(dr(0)))
        Next

        sbrAssemblies.Append("</assemblies>")

        Dim doc As New XmlDocument
        doc.LoadXml(sbrAssemblies.ToString())

        Dim trans As New System.Xml.Xsl.XslCompiledTransform
        trans.Load(Server.MapPath("Assembly.xsl"))

        Dim writer As New System.IO.StringWriter

        trans.Transform(doc, Nothing, writer)

        Dim result As String = writer.ToString()
        result = result.Replace("xmlns:asp=""remove""", "")

        ' Add to place holder on page
        phXML.Controls.Add(Page.ParseControl(result))

    End Sub

The click event I want to fire is:

Protected Sub lbnEdit_Click(ByVal sender As Object, ByVal e As
System.EventArgs)
        Dim sLoc As String = ""

        Try
            Dim lbnEdit As LinkButton = CType(sender, LinkButton)
            Dim strCommandArg As String =
CStr(lbnEdit.CommandArgument)
            Dim strCommandName As String = CStr(lbnEdit.CommandName)

' Testing purposes output values to verify click event is working
            Response.Write("Command name: " & strCommandName &
"<BR>Command Arg: " & strCommandArg & "<BR><BR>")
        Catch ex As Exception

        End Try
    End Sub

Any help is greatly appreciate.

ASP.NET controls only exist on the server side. You are writing them to the 
client! That will never work.

John,

That was my understanding of ASP.net controls as well.

However, I ran across this post
http://groups.google.com/group/microsoft.public.dotnet.xml/browse_thread/thread/a07e8a9515f4946c/2335a15f50447b9f?lnk=st&q=Problem+with+transform+XSL&rnum=4#2335a15f50447b9f

and thought I'd give it a shot as they said they were able to get it
to work with validation controls.

Here's a link to the article I read as well:

Can you show us how the string result looks that you pass to the 
Page.ParseControl method?

Martin,

Here is the string that is sent.

<table class="css_Panel" width="100%" >
  <tr>
    <th width="200">
				Type<br><asp:LinkButton id="lbnEdit308" Text="Edit"
CommandName="SA" CommandArgument="308" runat="server" />
    </th>
    <th width="50">Column 2</th>
    <th width="110">Column 3</th>
    <th width="100">Column 4</th>
  </tr>
  <tr>
    <td>Text</td>
    <td>Text</td>
    <td>Text</td>
    <td>Text</td>
  </tr>
</table>

It is added to a place holder on one of my pages. I am using asp.net
2.0 with a master page as well if that helps.

Martin,

Here is the actual text for the control I'm trying to create from the
transformation. The previous message left out the onclick attribute as
I was playing around with the code.


Type<br><asp:LinkButton id="lbnEdit308" Text="Edit"
CommandName="SA" CommandArgument="308" runat="server"
onclick="lbnEdit_Click" />

I am not sure what the problem is, you might want to ask in an ASP.NET 
group about ParseControl and the event problem. I don't think it is 
related to XSLT, I see the event handler not firing when I simply do
         Ph1.Controls.Add(Page.ParseControl("<asp:LinkButton 
id=\"lbnEdit308\" Text=\"Edit\" CommandName=\"SA\" 
CommandArgument=\"308\" runat=\"server\" OnClick=\"lbnEdit_Click\" />"));
without any XSLT being involved.

I tried to find a solution googling but so far I have only found posts 
about the same problem like e.g. 
<http://forums.asp.net/p/729540/729540.aspx#729540> but no solution 
other than using code to add event handlers once ParseControl gives you 
a control.

Got it to work.

Placed the code in the Page Init function and after doing the
Page.ParseControl I looped through the controls of my placeholder and
added event handlers as shown below:

For Each ctl As Control In phAssembly.Controls
            For i As Integer = 0 To ctl.Controls.Count - 1
                If TypeOf ctl.Controls(i) Is LinkButton Then
                    Dim lbnEdit As LinkButton = CType(ctl.Controls(i),
LinkButton)

                    AddHandler lbnEdit.Click, AddressOf lbnEdit_Click
                End If
            Next
        Next

Thanks for your time and help.
