We have an older version (2013.3.1010.45) of telerik and have recently started to see some errors with radchart.  How do we handle this type of error and what is the cause of this error?

Exception of type 'System.Web.HttpUnhandledException' was thrown.

Image could not be created    at System.Web.UI.Page.HandleError(Exception e)
   at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)
   at System.Web.UI.Page.ProcessRequest(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)
   at System.Web.UI.Page.ProcessRequest()
   at System.Web.UI.Page.ProcessRequestWithNoAssert(HttpContext context)
   at System.Web.UI.Page.ProcessRequest(HttpContext context)
   at ASP.search_mydashboard2_aspx.ProcessRequest(HttpContext context)
   at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
   at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

I can't seem to figure out how to keep the "Remove" button on the same line as uploaded media file.  When the file name is really short it stays on the same line but if the file name gets longer the "Remove" button drops down below.  There is plenty of horizontal space for both to be on the same line.

~Thx

Okay, this took me a while to track down as the source of the problem, but I am out of options here and at my wits end. Every conversation I see even close to this is at best 2 years old, most 2010 or older, so I am desperate for help.

 

Short version:

-- radGrid on the page, GridClientSelectColumn set as first column, grud set to have AllowMultiRowSelection="true"

-- after multiple items selected, radwindow used to allow user to edit selected item(s)

If at any time after the window appears (whether it closes or not) any button that does a postback - partial or full - always throws a "Unable to cast object of type 'System.Int32' to type 'System.String'." error. I remove the "AllowMultiRowSelection="true"" (or otherwise set it to "false") everything works perfectly. If it is true, I always get the error, specifically when the grid refreshes. It does not fire any server-side code; the code dies well before it even gets to that point. The same happens is I set a radbutton to be AutoPostback="false" but then try to refresh the grid using client code; if I skip refreshing the grid completely, but I must refresh the grid each time to ensure I have the latest data on it.

Hi EveryOne!

 

I have been working on my own skin with base on custom telerik skin for my website and I'm having trouble with the Calendar,

As you can see in the Image, the days and numbers are not fit in the whole box so you can see other numbers that are not suppose to be...

I'm looking forward to someone that can help :),

AllowedFileExtensions on RadAsyncUpload is case sensitive. So when setting AllowedFileExtensions to "doc, docx" it won't accept any DOC or DOCX extensions. How can I enable AllowedFileExtensions to be case insensitive?

Is there any inbuilt mechanism that would allow me to collapse (hide and reveal) sub trees within a hierarchical Diagram.

The functionality I'm looking for would visually hide any and all descendant diagram nodes where that node has no parents that are not already hidden.

Hello,

When I have the Telerik Rad Editor set to insert Paragraph tags for new lines, they also tend to insert additional information from the current line. This happens when the user hits Enter or when they click the New Paragraph tool bar item.

For example, I have added some custom buttons that insert placeholders into the code that I will then parse out with actual values as necessary. I am inserting HTML like this: <span title="Speakers">{{Speakers}}</span>

I like putting it in a span with a title so when they hover their mouse over it they see some additional information. 

But if this is on one line, surrounded by it's own paragraph tag, when I go to add another paragraph after it (to add additional text or placeholders or anything) user either the keyboard or toolbar item, the new paragraph will be:

<p><span title="Speakers">&nbsp;</span></p>

Instead of just:  <p>&nbsp;</p>

What can I do to insert JUST an empty paragraph? Why is it pulling my span tag in, too?

Thanks.

How do I change the background color of the title (), which is now green to blue?

And note that the title of the background color for MetroTouch skin has gone from blue to gray? Bug or changed?

Icon title = "warning," Is there a library? If, Where?

I've been trying to access and localize the pickers but with no success... Here are my test so far (it doesn't work of course).
Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load
     AddHandler RadGrid1.HeaderContextMenu.ItemCreated, New Telerik.Web.UI.RadMenuEventHandler(AddressOf HeaderContextMenu_ItemCreated)
 End Sub
  
 Protected Sub HeaderContextMenu_ItemCreated(sender As Object, e As Telerik.Web.UI.RadMenuEventArgs)
     If TypeOf e.Item Is RadDatePicker Then
         Dim picker As RadDatePicker = DirectCast(e.Item, RadDatePicker)
         picker.DatePopupButton.ToolTip = "Apri il calendario"
     End If
 End Sub

Also I discovered a very odd issue with the context menu while filtering datetime columns. If you set a culture with dd/MM/yyyy (italian for example) with 
       Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load
            If Not Me.IsPostBack Then
                RadGrid1.Culture = New CultureInfo("it-IT")
            End If
end sub

If I select 6/7/2013 (wich stands for July, 6 2013) in the first (or second) filter of HeaderContextMenu, this is correctly reported as 06/07/2013 in the GridDateTimeColumn where FilterDateFormat="dd/MM/yyyy" and DataFormatString="{0:dd/MM/yyyy HH:mm}" BUT is incorrectly reported (after filtering) as 07/06/2013 AFTER filtering happened.
I mean... in the context menu, I see italian calendar, I select the correct dd/MM/yyyy date and this appears correct in the textbox when I click on the date BUT after the filtering happens (postback) if I go back to the header context menu I see month and day inverted in the textbox like MM/dd/yyyy. Guess this is a bug of sort. Any suggestion to solve while waiting for bugfix?

Thanks in advance
