Hi all,

when I am creating a table in RadEditor(DNN6), I can assign a table layout defined by Telerik like "Telerik-reTable-1". But how do I customize my own table layout? Where do I find the source files?

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

Thanks

Editor

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>

similar to radupload in radgrid demo

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"

                            </telerik:GridBoundColumn> 
        
                            <telerik:GridTemplateColumn DataField="ArticleTitle" HeaderText="Article Title" UniqueName="ArticleTitle">

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

<telerik:RadSliderItem Text="11" Value="11" />

<telerik:RadSliderItem Text="12" Value="12" />

</Items>

</telerik:RadSlider>

The problem that its width when the page first loads is very small and looked crashed but after reloading pages it goes
that's the crashed slider image:
