Hello,

Could you inform me your current WebDesktop assembly version and Framework assembly version?
Have you try to use the latest assembly version?

If you don’t mind, could you help me to inform me how to reproduce your issue on my end?

You only got the error while you run (view in browser) your application in development environment?
However you didn’t get the error while run (browser) your application in deployment server?

Please ensure you are using the same application (and assembly file) between in development environment and deployment server. Because supposed to be there was no difference in results between in development environment and deployment server.

Thank you.

Regards,
Hans.

However you didn’t get the error while run (browser) your application in deployment server?

<ISWebDesktop:WebExplorerPane ID="WebExplorerPane1" runat="server" 

                            Height="100%" style="font-family: Calibri" Width="400px" 

                            EnableAnimation="False" XmlCompressionEnabled="True" 

                            RenderMode="RoundCorner" EnableViewState="False">

                            <Panes>

                                <ISWebDesktop:WebExplorerBar Name="Pane0" Text="" Visible="false">

                                </ISWebDesktop:WebExplorerBar>

                                <ISWebDesktop:WebExplorerBar Name="Pane1" Text="abc" Collapse="true" >

                                </ISWebDesktop:WebExplorerBar>

problem exist with
