Deployment issue with IIS 7

Hi,

we have developed an ASP.NET application which uses Telerik Rad Controls. The app works pervectly with the VS2008 development server. When I try to deploy it on IIS7

I get the error "sys is undefined".

A code-snippet from the debugger is attached below.

                    <script src="/MyApp-dev/Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=ctl00_ScriptManager1_HiddenField&amp;compress=1&amp;_TSM_CombinedScripts_=%3b%3bSystem.Web.Extensions%2c+Version%3d3.5.0.0%2c+Culture%3dneutral%2c+PublicKeyToken%3d31bf3856ad364e35%3ade-DE%3a3bbfe379-348b-450d-86a7-bb22e53c1978%3a52817a7d%3a67c678a8%3bTelerik.Web.UI%2c+Version%3d2008.2.826.35%2c+Culture%3dneutral%2c+PublicKeyToken%3d121fae78165ba3d4%3ade-DE%3a2b1b618c-2ad2-4d4e-8b5a-afa3e17baf61%3a393f5085%3bTelerik.Web.UI%2c+Version%3d2008.2.826.35%2c+Culture%3dneutral%2c+PublicKeyToken%3d121fae78165ba3d4%3ade-DE%3a2b1b618c-2ad2-4d4e-8b5a-afa3e17baf61%3a34f9d57d%3bTelerik.Web.UI%2c+Version%3d2008.2.826.35%2c+Culture%3dneutral%2c+PublicKeyToken%3d121fae78165ba3d4%3ade-DE%3a2b1b618c-2ad2-4d4e-8b5a-afa3e17baf61%3a526d426%3bTelerik.Web.UI%2c+Version%3d2008.2.826.35%2c+Culture%3dneutral%2c+PublicKeyToken%3d121fae78165ba3d4%3ade-DE%3a2b1b618c-2ad2-4d4e-8b5a-afa3e17baf61%3a4b40c3e6%3bTelerik.Web.UI%2c+Version%3d2008.2.826.35%2c+Culture%3dneutral%2c+PublicKeyToken%3d121fae78165ba3d4%3ade-DE%3a2b1b618c-2ad2-4d4e-8b5a-afa3e17baf61%3a9703c1f0%3bTelerik.Web.UI%2c+Version%3d2008.2.826.35%2c+Culture%3dneutral%2c+PublicKeyToken%3d121fae78165ba3d4%3ade-DE%3a2b1b618c-2ad2-4d4e-8b5a-afa3e17baf61%3a80c4ad6d%3bTelerik.Web.UI%2c+Version%3d2008.2.826.35%2c+Culture%3dneutral%2c+PublicKeyToken%3d121fae78165ba3d4%3ade-DE%3a2b1b618c-2ad2-4d4e-8b5a-afa3e17baf61%3a527acb41%3bTelerik.Web.UI%2c+Version%3d2008.2.826.35%2c+Culture%3dneutral%2c+PublicKeyToken%3d121fae78165ba3d4%3ade-DE%3a2b1b618c-2ad2-4d4e-8b5a-afa3e17baf61%3aa9723048%3bTelerik.Web.UI%2c+Version%3d2008.2.826.35%2c+Culture%3dneutral%2c+PublicKeyToken%3d121fae78165ba3d4%3ade-DE%3a2b1b618c-2ad2-4d4e-8b5a-afa3e17baf61%3aa3f85c94%3bTelerik.Web.UI%2c+Version%3d2008.2.826.35%2c+Culture%3dneutral%2c+PublicKeyToken%3d121fae78165ba3d4%3ade-DE%3a2b1b618c-2ad2-4d4e-8b5a-afa3e17baf61%3a819163f9" type="text/javascript"></script>

The Telerik.Web.UI.WebResource.axd is not available (404) when I call it directly from the browser.

Does anyone have an idea what's wrong here?

RadScriptManager & EnableScriptCombine & ScriptReference(s)

Is the RadScriptManager supposed to combine javascript files that are referenced in ordinary ScriptReference blocks?

E.g.

<telerik:RadScriptManager EnableScriptCombine="true"...>
<Scripts>
<asp:ScriptReference Path="~/include/About.js" />

...

Script combining is working for user controls etc. but I am not seeing anything happen with the above scenario.

Hide context menu after calling set_cancel

Hello,

Some menu item click events I handle on the client and some on the server:

<telerik:RadTreeView ID="fileTree"
runat="server"
OnContextMenuItemClick="fileTree_ContextMenuItemClick"
OnClientContextMenuItemClicking="clientContextMenuItemClicking">

When I call eventArgs.set_cancel(true); on a client side event handler that I do not want to be processed on the server, the context menu does not disappear. Is there a way to hide the menu or should I be doing something different?

   function clientContextMenuItemClicking(sender, eventArgs)
   {
    var node = eventArgs.get_node();
    var item = eventArgs.get_menuItem();
    var tree = node.get_treeView();

    if (item.get_value() == "DeleteFile")
     if (!confirm("Are you sure you want to delete this file?\n\n This cannot be undone."))
      eventArgs.set_cancel(true);
   }

Many thanks! Ryan

Collapse after timer ticks

Hello,

I have a grid with for each item a detail table. The data for this grid are filled out using NeedDataSource and DetailTableDataBind events.
I also have a time which is in charge of rebinding the grid every 5 seconds.

My problem comes when I have expanded an item of the grid, in order to see its detail table, and the timer ticks. Then the item is automatically collapsed...

How can I avoid this automatic collapsing.
My Telerik version is v2008.1.619.35.

Here are sample codes :

    
            <telerik:RadStyleSheetManager runat="server"> 
        
            </telerik:RadStyleSheetManager> 
        
            <telerik:RadScriptManager ID="RadScriptManager1" runat="server"> 
        
            </telerik:RadScriptManager> 
        
            <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server"> 
        
                <ajaxsettings>

                        <UpdatedControls> 
        
                            <telerik:AjaxUpdatedControl ControlID="RadGrid1" /> 
        
                        </UpdatedControls> 
        
                    </telerik:AjaxSetting> 
        
                    <telerik:AjaxSetting AjaxControlID="RadGrid1">

Server side loop through visible rows

I have a feeling this should be simple but I can't for the life of me get my head around it.

I want a clientside doubleclick event to do a simple javascript window.open() with the URL derived from data in the grid row clicked.

My first javascript function looked like this:

    
            function RowDblClick(sender, eventArgs) {  
        
            switch (eventArgs.get_itemIndexHierarchical()) {  
        
             case '0':  
        
                window.open('urlhere','','')  
        
             case '1':  
        
              ....etc  
        
            }  
        
            }

Simple enough. The calculation of the URL is quite intensive so I don't want to do it more than I have to, so what I want to do is loop through the visible rows
and generate the code I need.

Any help would be appreciated

RadGrid Postback Rebind

Hi,

This might be a silly question to ask but being a newbie I shouldn't worry about being silly if I want to know for sure what is possible and what not.

Anyway, my question is:

I have a RadGrid on page and everytime I change cell in Grid, I do postback using AjaxManager, Grid seems to go through its whole process of Rebind() (I have this method defind ItemCreated, ItemDataBound, ColumnCreated, PreRender). It takes several seconds before I get response from AjaxManager. Once I get response, I am doing whole lot of other stuff from JavaScript using the response.

I was wondering if there is a way to execute Rebind() when I needed if not just execute the function defined for AjaxManager and return the response. I want to minimize the time it's taking to give me response from server side.

thank you very much, appreciate your help.
