IE6: Internet Explorer cannot open the Internet Site

Hello,

I have run into a problem where our Intranet application that is running at multiple physical sites will get the error
"Internet Explorer cannot open the Internet Site".

At one site it occurs much more often that the other sites.

The customer is currently using IE6 and we are using ASP.Net controls.

I have not been able to reproduce in a development environment, nor can I produce a sample application that demonstrates the error.

This link looks similar to the error:http://www.telerik.com/community/forums/aspnet-ajax/vs-extensions/website-on-server-returns-internet-explorer-cannot-display-the-webpage.aspx

I am hoping that Telerik or anyone else can offer up some suggestions of things to try or look at to resolve this issue.

Thanks for your help,

Mark.

Has anyone an idea how to solve this?
A step by step instruction is welcome.

XMLDatasource retain treeview state

HI,

I am using xmldatasource to populate the treeview. Like in the example: http://demos.telerik.com/aspnet-ajax/treeview/examples/programming/xmlfile/defaultcs.aspx

Only extra property I have in XML node is 'NavigateURL' property. When I click the node it is loading the page specified in the navigateurl, but the treeview is collapsing. How to retain the state in this case?

<Tree>

<Node Text="Sample" NavigateUrl="~/Sample.aspx" Expanded="False" ></Node>

</Tree>

I have something similar to the demo; however my code uses a Form Template to define the "editing" form fields...the demo doesn't.

How can i leverage the demo code but reference a FormTemplate for RadUploading to a database?

My code has this...

    
            <Columns> 
        
                            <telerik:GridBoundColumn DataField="ArticleID" DataType="System.Guid" HeaderText="ArticleID"

In the code i have listed...i was testing with both the RadUpload and the AsyncRadUpload...not sure would be a better fit.

Also, i'm not sure if i need to include the logic from the demo for the postback issues?

Thanks,

"Object reference not set to an instance of an object." during Async Upload

I'm using a file manager control with AsyncUpload enabled:

<telerik:RadFileExplorer ID="expTCDrive" runat="server" EnableCopy="true" OnClientFileOpen="OnClientFileOpen"

EnableFilterTextBox="true" EnableFilteringOnEnterPressed="false" Width="750px"

OnClientFolderChange="OnClientFolderChange" Height="500px" EnableAsyncUpload="true">

<Configuration MaxUploadFileSize="52428800" />

</telerik:RadFileExplorer>

From time to type, we are receiving the following exception

Error in: https://oursite/ourfolder/Telerik.Web.UI.WebResource.axd?type=rau

Error message: Object reference not set to an instance of an object.

Stack trace: at Telerik.Web.UI.AsyncUploadHandler.ProcessRequest(HttpContext context)

at Telerik.Web.UI.HandlerRouter.ProcessHandler(String handlerKey, HttpContext context)

at Telerik.Web.UI.WebResource.ProcessRequest(HttpContext context)

at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()

at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

Any ideas why this would be happening? I've tried several different things and was hoping that I could recreate it, but I can't. I was thinking that perhaps it was being caused by the Upload button being enabled while it was still uploading in the previous version, but with the latest release, that issue has been fixed and the error still occurs. If it helps, I can package up the entire project and send it as a support ticket.

Thanks,
Adam
