WebResource.axd Same URL Different Results

I hope this is the right forum topic...

I'm having a situation where Telerik is generating a URL to a javascript file which is cached at the client. When we release a new build the same URL is produced but the content of the javascript is different. However, because the client is caching the file (or the URL, I should say) the correct javascript content isn't being downloaded.

Our environment is as such:

Telerik version 10.2.7.13
Windows Server 2003
.Net Framework 4.0
ASP.NET Forms

I don't have anything else to go one from here to troubleshoot the problem any further. We've search for caching issues within ASP.NET, IIS, etc... The way we found the problem was by javascript failing on an unhandled exception. The javascript is from a WebResource.axd... We grabbed the content of the javascript as well as the URL, clear the browser cache and requested the URL, again. We found the URL being generated were Identical but the javascript content was different. Any help getting around this issue is greatly appreciated. We've narrowed it down to Telerik's scripting manager generating these URLs but we don't know how to make it generate all new keys in the case of a new release of our code.

Any help on this matter is very much appreciated.

Regards,

Can you add a property to the RadScriptBlock such that at render time we can specify WHERE the script tag renders?

I'd like to send my scripts to the bottom of the page on Render...

Rad Ajax is not working well with jquery on the same page

I have a typical asp.net page where I have rad menu and rad grid. Also I have 2 drop down controls. When a drop down is selected, I have jquery load function that loads different aspx page (lets call a.aspx) in a empty div on demand. This aspx page is a form with its own submit button to save/update data.
After this aspx page is loaded, if I go to menu and select any menu item, it does not take me to the menu link, it takes me to a.aspx page. Is this happening due to some bug in rad ajax.

Please help.
Thanks,

grid editing/inserting not working

I have a grid with 1 master table and 1 details table. On my development machine when I expand the detail section then click the 'add a new record' button, the edit section appears and I can add some data, then save. After uploading to a hosted environment, clicking 'add new record' does nothing ! I get the ajax animated icon, but no edit section appears so I cant input any data.

I have a similar grid on another page and it works perfectly. Can anyone help ? this has now gone live but it wont work. Am I missing something ?

Show contextmenu when hovering on node instead of right-click

I implemented the context menu for the treeview and everything works fine. No my client wants me to show the context menu when hovering vs making the user rightclick, like the HoverMenu is in the Ajax Control Toolkit

http://www.asp.net/AJAX/AjaxControlToolkit/Samples/HoverMenu/HoverMenu.aspx

Is there another way to open the ContextMenu? Hopefully there is a Javascript function that I can call to show it for each node.

thanks

expand / collapse arrow

I am using a RadPanelBar -- I am currently hiding the expand and collapse arrows using the following code:

.rpExpandHandle

{

display: none!important;

}

.rpCollapseHandle

{

display: none!important;

}

This works great -- except now I need to add another RadPanelBar to the same page where I need to show the expand and collapse arrows.

I read in the following help file that if you set the imageUrl and imagePosition to right, then it will replace the image. Unfortunately I can't get that to work.

Here's the help link:

http://www.telerik.com/help/aspnet-ajax/panel_appearanceitemimages.html

Here's my code sample:

<telerik:RadPanelBar runat="server" ID="SupportPanelBar" Width="150" >

<ExpandAnimation Type="None"></ExpandAnimation>

<CollapseAnimation Type="None"></CollapseAnimation>

<Items>

<telerik:RadPanelItem Text="TeamSideline" Expanded="True" PreventCollapse="true" NavigateUrl="/Home.aspx" ImagePosition="Right" ImageUrl="~/img/icon_delete_active.png" SelectedImageUrl="~/img/icon_delete_active.png">

<Items>

<telerik:RadPanelItem Text="Support Menu" NavigateUrl="/Support/Home.aspx" BackColor="#D7D8D8" />

<telerik:RadPanelItem Text="Public Downloads" NavigateUrl="/TsMoreInfo.aspx" BackColor="#D7D8D8"

/>

</Items>

</telerik:RadPanelItem

</Items>

</telerik:RadPanelBar>

And the output is attached. I am using the telerik dll -- 2010.3.1109.40

Your help is appreciated.

Thanks,
Todd.
