I read somewhere that you are going to implement 2d barcodes

do you have an ETA for this

we are looking for a tool to create 'user definable' barcode layouts for test tubes, slides etc but definately require slides to have 2d barcodes due to the limitaions of the size of the barcodes

we use your tools for our client, so hoped we could create a barcode designing/printing solution too but definately require 2d

thx

Hi.  I have an old Silverlight application that uses the Telerik Silverlight Map control using the Microsoft Bing Map provider.  Silverlight is obsolete, but we are trying to keep it running for as long as we can.

The Telerik Silverlight Bing Map stopped working.  The map control loads, but no map is being displayed.  A http packet trace shows an HTTP 404 error against http://dev.virtualearth.net when requesting clientaccesspolicy.xml.  See screenshot:

Is there a way to fix this?

Hello,

I have an old Silverlight application using the `Windows 7` theme.

In this application, I'm using many controls and the `app.xaml` file contains the following theme files:

After installation Ui for Silverlight R1 2022 SP1, the application no more starts: it complains about a referenced static resource that is missing, in the `Telerik.Windows.Controls.RichTextBoxUI.xaml` file.

Replacing this file with the one from version R1 2022 makes it work again.

You should really test Silverlight application while you're adding new functions!

 

Hello,

I have an old Silverlight application with the following in the App.xaml file:

After updating to the latest, the application no more works: it crashes as soon it displays a GridView control, without any useful error message. It takes me a long time to find the error because I can no more run the application with a debugger and I have no useful error message.

As the application was running fine before I updated Telerik UI for Silverlight, I suppose that the above line is the culprit. Unfortunately, I don't know the previous version of Telerik UI for Silverlight that was used for the application.

I hope this is enough for you to find the bug.

 

Best regards

I am zipping the file using the Telerik.Windows.Zip. When i extract the zip file manually using winzip, it throws the below error

!   C:\Users\Public\Music\Sample Music\New folder\3.zip: CRC failed in 3.zip.xml. The file is corrupt.

It does work sometime.

using (Stream stream = viewModel.OpenStream())
                    {
                        if (stream != null)
                        {
                            using (ZipPackage zipPackage = ZipPackage.Create(stream))
                            {
                                zipPackage.AddStream(new MemoryStream(GetXmlData(tutorial)),viewModel.Filename+".xml");
                                 
                            }
                        }
                    }

I'm using RadPdfViewer control, and it works correctly if I write my code like this:


But I want to load files that are hosted on a server (within the same network). I tried this:


As a test, I try a local file


Is there a way to do it?

PS: All the files have read permissions are published

Hi all.
I'm using the QueryableCollectionView to filter mu RadChart. With this class i'm able to retrieve the original collection of data (using the SourceCollection property). But, how i can retrieve the filtered collection of data?
Thanks in advance

Getting error like "The tag 'RadComboBox' does not exist in XML namespace 'http://schemas.telerik.com/2008/xaml/presentation" this.

I have tried to implement a line chart along with Notes,. but the problem arises when 2 notes are very close to each other they overlap and are not readable. I tried adding margin but could not achieve a good result even with rotation it looks very absurd. 

I am trying to figure out a way where I can display the notes in one series alternatively top or down. But I can't find anything. I only got an option to display notes top or down per series. Need help with this?

Or if any other way I can achieve it with a readable format

While viewing a virtual collection in the gridview if I load the first page, select a row, then move down to a page after the second page and attempt to close the multi selection with the shift key (multi-select across pages) the following error is thrown, any way to prevent this short of removing extended selection from the grid (currently have functionality tied to multiselect), maybe reset selection when page moves?:
