Greetings!

I want to open a PDF file in a new window, not in the current page. It was a friend who did this and he is on vacation, so I must figure it out by my own :)

I have the following ascx code:

<asp:DataList id="lstAnexos" Runat="server" EnableViewState="false" BorderStyle="Solid" BorderWidth="1" Width="100%">       <ItemTemplate>
  <!--<asp:HyperLink id="anexoLink_old" runat="server" Visible="true" Target=_blank text='<%# DataBinder.Eval(Container.DataItem,"text") %>' navigateurl='<%# FormatURL(DataBinder.Eval(Container.DataItem,"NavigateUrl")) %>' BorderStyle="NotSet" width=100%/>-->
  <asp:LinkButton ID="anexoLink" CssClass="Normal" Runat="server" OnCommand="lnkDLFile_Command" CommandArgument='<%# DataBinder.Eval(Container.DataItem,"NavigateUrl")%>'><%# DataBinder.Eval(Container.DataItem,"NavigateUrl")%></asp:LinkButton>
 </ItemTemplate>
</asp:DataList>

And in the Vb file:

Private Sub loadAnexos(ByVal objArticle As ArticleInfo)

 Dim sAnexos As String = objArticle.Anexos
 Dim arAnexos As New ArrayList
        Dim item As HyperLink
        Dim sText As String
        Dim sURL As String

        If (Not sAnexos Is Nothing) And (sAnexos <> "") Then
            For Each sURL In sAnexos.Split(",")
                If sURL <> "" Then
                    Dim fc As New DotNetNuke.Services.FileSystem.FileController
             Dim fi As DotNetNuke.Services.FileSystem.FileInfo

                    If sURL.StartsWith("FileID=") Then
                        fi = fc.GetFileById(sURL.Substring(7), PortalId)
                    Else
                        fi = fc.GetFile(sURL, PortalId, "")
                    End If
                    If Not fi Is Nothing Then
                        sText = fi.Folder & fi.FileName
                        item = New HyperLink
                        item.Text = sText
                        item.NavigateUrl = sText
                        arAnexos.Add(item)
                    End If
                End If
            Next
        End If
        lstAnexos.DataSource = arAnexos
        lstAnexos.DataBind()

End Sub

(I don't know why the friend who implement this module put the comments on the hyperlink and used a linkbutton instead!)
I suppose maybe with item.Attributes.Add(..) or javascript window.open I could get something... Concerning the hyperlink, I thought the same and switched comments, but no result! I tried item.Target = "_new" or item.Attributes.Add("target", "_new") and it still opened in the same window. Even with javascript (but here I don't think I did it right)...

I also tried the linkbutton solution, but I cannot seem to enter the lnkDLFile_Command method (I experimented the ItemCommmand which I successfully use in other situations, but I think it requires DataGrid and not DataList. When I changed from Grid to List I got this odd error: The base class includes the field 'attachmentGrid', but its type System.Web.UI.WebControls.DataGrid is not compatible with the type of control System.Web.UI.WebControls.DataList).

The code in lnkDLFile_Command is the following:

'Protected Sub lnkDLFile_Command(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.CommandEventArgs)
            'DownloadFile(e.CommandArgument.ToString())
            'BindFolderTree()
        'End Sub

As you can see it is commented. These methods are used in another module of this DotNetNuke portal and they are working.

I really believe the hyperlink is the better solution (as it is the control created in runtime) so if you can give some help with this I'd really thank you! I've been working on this during the last two days and still no light!

Thanks in advance for your help!
