Hi,

Environment:
- Windows Vista with Service Pack1
- IIS 7
- RadControls for ASP.NET AJAX Q2 2009 NET35
- MS Visual Studio 2008

Error Message in Visual Studio Design Page:

Error Rendering Control - RadScriptManager1An unhandled exception has occurred.

Could not load file or assembly 'Telerik.Web.UI, Version=2009.2.701.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4' or one of its dependencies. The system cannot find the file specified.

_______________________________________________________________________________

I am creating a simple Website with just 1 page. Getting the above error message. I also can't register Telerik.Web.UI.WebResource.AXD from Visual Design Page because RadScriptManager Show Smart Tag is dimmed out, like read only.. In my Web Config File, I followed the instructions to register HTTPHandler from this Page.

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

Below is my WEB Config, Default.aspx and Code Behind File. Please help. Thanks

ToolProviderID and Symbols bug?

Hi there,

I have the following scenario:

8 Editors on a page which all use the same Toolbar, so I implemented ToolProviderID so that all Editors use the Toolbar off the first Editor.

The toolbar is shown properly exept for the <symbols> section which shows the default list and not my custom defined list in the toolbar XML.

Any suggestions?

Set startEdit on node in ClientNodeEditing

Hi Everybody,

I would like to crete new node on clientside and set this node to edit mode. And when user doesn't change the label and click outside, i would like show radalert and cancel postback - so far so good. But after that I would like to set node to edit mode again. And I'm getting strange unhanded exceptions from code. This is my snippet:

                    function onClientNodeEditing(sender, eventArgs) {         
                            var node = eventArgs.get_node();         
                            var oldText = node.get_text();         
                            var newText = eventArgs.get_newText()         
                            var tree = $find("<%= ThreadRoot.ClientID %>");         
                                     
                            if (newText == oldText) {         
                                radalert(Please change name of category!");         
                                        
                                tree.trackChanges();         
                                node.startEdit();         
                                tree.commitChanges();         
                     
                     
                                eventArgs.set_cancel(true);         
                            }         
                        }         

Any ideas? for example this code returns Cannot set property 'onblur' of null (G Chrome) and stops execution with Uncaught RangeError, Maximum call stack size exceeded

Dock, some difficulties

Im trying to create a dock zone, with 5 docks, and orientation horizontal, its a priority like utility, whats in the left its more important.

Problems:

    I cant set the height of each dock, another controls will be added inside. But, in firefox, these docks get very big. To reproduce this you just need a docklayout, a dockzone (no height), 2 docks inside (no height), and orientation horizontal. The docks dont feet to the content inside, but to the page height size (??). A workaround its to change the dock height when adding controls, but its very boring to do, im not sure how many text will come from database, and im not using a monospace font.

    I do need a space between each dock, what im trying to get adding a padding in the raddock_custom, and it works very bad, first because IE draw the help lines with padding, around and far from the dock, and FF seems to be adding the padding to the help lines and the virtual dock size each time a control is dragged around.

    In a dockzone without any width, the help lines dont show, and becomes impossible to drag docks, except the last one.

If anyone can point me a direction to solve these problems i ll be very glad.

Regards

Iterate Page Controls Using Reflection

Hi,

I have a RadTreeView control which I have bound to the directory sctructure of a website very similar to Telerik's demo under Application Scenarios / Directory Structure found here. Anyway, what I'd like to do is when a user selects a page from the tree, I want to iterate through that page (not navigate to it) using reflection and list out the various controls available on the selected page in order to perform various administrative purposes. This is easy enough for User Controls as I can just use LoadControl to gain access to an instance of a user control and then reflect through it to pull out control references. But an actual page is much different. I can't seem to find a way to either get a reference to the page in question or reflect the page. I think the nature of Partial Page Classes has something to do with it.

Anyway, if anyone has run into a similar issue, I'd love to hear how you worked around it.

Thanks in advance,
Tom

Problem with GridTemplateColumn and SortExpression

Hello !
I use GridView to bound my data from Business layer.
I have some service:
BLProvinces and BLDistricts
I used GridView for displaying List<District> ( DistrictID,Name,ProvinceID).
but I did not want to display ProvinceID and...I used GridTemplateColumn:

    
             <telerik:GridTemplateColumn HeaderText="ProvinceName" SortExpression="????">         
        
                    <ItemTemplate>            <%#BusinessLayer.BLProvinces.SelectRecordByID((long)Eval("ProvinceID")).Name%> 
        
                    </ItemTemplate> 
        
                    </telerik:GridTemplateColumn>

I want to Sort ProvinceName but I dont know what SortExpression ?
Help me! thanks your very much !.

UserControl RADAJAX_HIDDENCONTROL

Hi,

i have Problems with the RadAjaxManager:

1.) I have an Page that holds an AjaxManager
2.) I have (two) UserControls who call this AjaxManager to add AjaxSettings:

    
            RadAjaxManager1.AjaxSettings.AddAjaxSetting(ButSchaetzen, ButOk, null);

3.) When I rise an Event on the Button ButSchaetzen, then the Event is processed correctly, but the Control (ButOk) disappears from the UserControl.

When I try to search with the IE - DOM Explorer then I see the following:

    
            document.getElementById('ruhestandcheck_UcRentenschaetzer1_ButOk').innerHTML

Results in:

    
            RADAJAX_HIDDENCONTROL

I can't figure out why this happens.
- In the Event of ButSchaetzen I set ButOk.Enable = true;
- Nothing else I do with the Button
- The same happens to all other Controls I added to the AjaxManager

The AjaxManager - HTML Code looks like this:

    
            <radA:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest" EnablePageHeadUpdate="false"   
        
                      ClientEvents-OnRequestStart="requestStart()" ClientEvents-OnResponseReceived="responseReceived()" ClientEvents-OnResponseEnd="responseEnd()" 
        
                      DefaultLoadingPanelID="AjaxLoadingPanel1">  
        
                          <AjaxSettings > 
        
                          </AjaxSettings>             
        
                      </radA:RadAjaxManager>

What can be the Reason why the AjaxManager set the Controls to "RADAJAX_HIDDENCONTROL"?

Regards

Rendering problem

ComboBox renders incorrectly on IE8, but fine on FF. Items box seems slide 10px to left and about 15px up
And also there is a design time problem. It shows another arrow.
Please see attached files.

There is no style on page, just script manager and combobox.
Version is : 2009.3.1401.35

Any ideas?
