Blurred not clear text in Disabled Combobox

Hi Team,
I have a problem with the combo boxes i'm using. Whenever i disable the comboboxes the text inside them becomes blurry and not clear. If i place the mouse over the combobox the text becomes fine. But if i move the mouse a way from the combobox it becomes blurry and not clear again.
Is this a defect in the Telerik component i'm using? Could you help please.
Thanks,

Skin lost on non-ajax post back

Hi Guys,

I've been using RadControls for a while now and I've been able to fix most of my issues but this one has me completely stumped. Thankfully, I was able to recreate it in an empty project.

ASPX:

    
                    <asp:ScriptManager ID="ScriptManager1" runat="server">  
        
                    </asp:ScriptManager> 
        
                    <asp:UpdatePanel ID="UpdatePanel1" runat="server">  
        
                        <ContentTemplate> 
        
                            <telerik:RadDatePicker ID="RadDatePicker1" runat="server" Skin="WebBlue">  
        
                            </telerik:RadDatePicker> 
        
                            <br /> 
        
                            <br /> 
        
                            <asp:Button ID="Button1" runat="server" Text="toggle visibility" /> 
        
                        </ContentTemplate> 
        
                    </asp:UpdatePanel> 
        
                    <br /> 
        
                    <asp:Button ID="Button2" runat="server" Text="post back" />

VB:

    
                Protected Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click  
        
                    Me.RadDatePicker1.Visible = Not Me.RadDatePicker1.Visible  
        
                End Sub

To recrate the problem:
1. Press the 'toggle visibility' button to hide the RadDatePicker.
2. Press the 'post back' button to do a non-ajax postback.
3. Press 'toggle visibility' again to show the RadDatePicker.
4. Now open the calendar of the date picker and it will have lost its skin.

This happens no matter what browser I run it in. I have also already tried swapping out the Rad UpdatePanel/ScriptManager for MS AJAX ones. I have seen similar things happen with other Rad controls in the same situation (which is why I'm posting this in general discussions) but I'm just using DatePicker here for simplicity. Thanks in advance for any help you can give me.

ASP.NET - Web Pages, Web Forms or MVC

Ok I just want to get your opinions! I started as a classic asp designer and now I have been working with Web Forms for the last 2 years.

I am wondering which one of these technologies I should master to further enhance my career.
I like the idea of Web Pages being more like the way classic ASP was designed but I want to learn the best way to proceed in the future.

RadToolBarButton and returning a file

Hi,

I want to sent a text-file to the client in response of clicking a toolbarbutton.
The code to send the file:

Response.ContentType = "text/txt";

Response.AppendHeader("Content-Disposition", "attachment; filename=project_input_export.txt");

Response.TransmitFile(Server.MapPath("~/Export/project_input_export.txt"));

Response.End();

When I click on the the toolbarbutton I get the following error:
=============
Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.
Details: Error parsing near '##EXPORT##: 13-mrt-1'.
=============

When I call the same code from a RadButton the file is transmitted correctly.
Why can't I get the file from a toolbarbutton?

RadScheduler is always minimized in Internet Explorer

I've implemented RadScheduler in our website. In IE browsers (7, 8, and 9) only the header is shown when the page is first displayed. You have to click on the header in order to view the whole month.

I can set the "overflowbehavior" to "expanded" and it will display fully, but it expands past the boundaries for the size of the control that we want on the page.

The control displays just fine in Chrome and Firefox w/o the overflowbehaviour value being set, but it will not display correctly in IE.

Is this a known issue with the control or is there anyway around it?

Custom Handler scenario throwing an error

I implemented a basic custom handler similar to the Custom Handler demo on this page:

http://demos.telerik.com/aspnet-ajax/upload/examples/async/imageuploader/defaultcs.aspx?product=asyncupload

However every time I try to upload a file the visual studio debugger pops up a couple different client errors and takes me a spot in the telerik.web.ui.webresoure_2.axd dynamic file to a specific line:

if(!e){throw"Error while uploading, "+i;

The pop error messages are:

Microsoft JScript runtime error: Unhandled Error in Silverlight Application The remote server returned an error: NotFound.   at System.Net.Browser.AsyncHelper.BeginOnUI(SendOrPostCallback beginMethod, Object state)
   at System.Net.Browser.BrowserHttpWebRequest.EndGetResponse(IAsyncResult asyncResult)
   at UploadPrototype.MainPage.ProcessResponse(IAsyncResult asyncResult)
   at System.Net.Browser.BrowserHttpWebRequest.<>c__DisplayClassd.<InvokeGetResponseCallback>b__b(Object state2)
   at System.Threading.QueueUserWorkItemCallback.WaitCallback_Context(Object state)
   at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean ignoreSyncCtx)
   at System.Threading.QueueUserWorkItemCallback.System.Threading.IThreadPoolWorkItem.ExecuteWorkItem()
   at System.Threading.ThreadPoolWorkQueue.Dispatch()
   at System.Threading._ThreadPoolWaitCallback.PerformWaitCallback()

AND

Microsoft JScript runtime error: Unhandled Error in Silverlight Application Failed to Invoke: _onSilverlightError.   at System.Windows.Browser.ScriptObject.Invoke(String name, Object[] args)
   at UploadPrototype.EventManager.SilverlightError(String message, Int32 index)
   at UploadPrototype.MainPage.<>c__DisplayClass1f.<ProcessResponse>b__18()

Some help please.
