Hi,

The new build (9.0.20.2) did fix my previous problem (Access to Grid control from within the starttask of a progressbar).
Thank you.

After the upgrade, however, some of my user controls would not render in the visual studio 2008 design view (although these are still functioning as expected). I have narrowed it down to the fileexplorer control and have attached below a simple example of the problem, with a fileexplorer control containing only text in the content template.

The designer error message is:"an error occured while rendering the control:Object reference not set to an instance of an object."

Any idea where that can come from?

H

Code: Visual Basic.NET

Copy

Partial Class Control_FileExplorer
    Inherits System.Web.UI.UserControl
    Public Event UploaderEvent As EventHandler

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        FileExplorer1.RootFolder = "C:\"
    End Sub

End Class

Code: HTML/ASPX

Copy

<%@ Control Language="VB" AutoEventWireup="false" CodeFile="Explorer_test.ascx.vb" Inherits="Control_FileExplorer" %>

  <%@ Register assembly="EO.Web" namespace="EO.Web" tagprefix="eo" %>
   
    <eo:FileExplorer ID="FileExplorer1" runat="server">
        <LayoutTemplate>
            template
        </LayoutTemplate>
</eo:FileExplorer>

I am having the render issue with the upgraded installed today.

1. EO Demo sidebar does not render.
3. Grid Views with a sql reader databind do not render data... frame and data count (via label) is displayed.

Actually, tried the in Firefox and ok...
