We just upgraded our WinForm UI from Q3 2013 to Q2 2014 and we started getting a "An unhandled exception of type 'System.TypeinitializationException' occurred in unknown module" before our 'Main' method is ever hit in Program.cs. This didn't occur when we referenced the Q3 2013 assemblies. I've attached the error and our reference list from Solution Explorer in VS 2013 Update 2.

When I choose a new WinForms project, please give me the option of having form1 be a RadForm, rather than a Windows Form.

This way, I have to  change the new project as soon as it is created (or copy over some saved code).

 To reproduce: 
 1. Download the Telerik_UI_For_WinForms_2014_3_14_1202_Dev_NuGet.zip and extract on computer
 2. Create a project which contains RadPdfViewer and RadPdfViewerNavigator
 3. Install all nuget packages
 4. You will see that the Telerik.WinControls.PdfViewer.dll is not installed because is not included in the package.

Workaround: 
Download the zip file with Dlls and themes only (Telerik_UI_For_WinForms_2014_3_14_1202_Dev_hotfix.zip) from your account.

Resolution: 

The new nugget package is added in our suite. Its name is UI.for.WinForms.PdfViewer.[Version].nupkg. 

I've started to use your controls again after a bit of a break. I find myself hunting all over the properties to find the ones I need. How about an option to "pin" a few properties  so that they will be at the top of the list, so they are easy to find?

Our development process includes several applications that use the UI for WinForms. As such, we will download the latest release and evaluate all of our applications against it prior to updating all of our developers and our build servers. However, using the Control Panel does not provide any option for maintaining the previous install, so whichever developers are doing the evaluation have to manually reinstall the prior version, or manually install the new version, in order to be able to roll back if we decide not to adopt the latest release. 

Please add an option in the control panel to maintain the previous version when installing updates.

I see no use for the templates that are currently provided. I'm never going to build a new Word or Outlook type application. Some templates that might be useful would be along the lines of structure for business apps. Something that would give a framework for building apps for business use.

I have updated my OS to Win 10 from Win 8.1 and now none of the RadForms will open in VS 2015 Designer. Some esoteric error message: "Value cannot be null. Parameter name: instance" is displayed. Is there something I could do other than re-installing the entire Telerik product line?

hi,

when upgrading from telerik winforms r3 sp1 2018 to r1 2019 using vb.net 2012 i received an error

what is we have to do

regards

Theme Names aren't sorted in the Properties window of VS2019

I upgraded to latest version of Win UI controls, and opened a project for an Outlook COM Addin. There has been no problems upgrading Telerik controls in that project until now. It's a Class Library project with Telerik forms in it. Now I have to change project type to Windows Forms, upgrade Telerik and then back to Class Library. Silly really... :)

Steps to reproduce:

1. Install R1 2021 SP1 (2021.1.204)
2. Create a Telerik WinForms project and drag a RadTostNotificationManager from the Toolbox and drop it onto the form. The following two references are required for using RadToastNotification:

   

   

   The important information here is the version of the Microsoft.Toolkit.Uwp.Notifications: 6.1.0.0

   

3. Run the Upgrade Wizard and upgrade to R2 2021 (2021.2.511):

After the upgrade process is successfully completed, you can see that the Toolbox version is successfully updated as well as the Telerik references in the project:

However, the version of the Microsoft.Toolkit.Uwp.Notifications still remains 6.1.0.0 even though in the installation folder we distribute the updated version 7.0.0.0:

Then, if you try to build the project, you will see the following error message:

Workaround: Remove the existing Microsoft.Toolkit.Uwp.Notifications assembly and add it anew using the references from the installation folder: C:\Program Files (x86)\Progress\Telerik UI for WinForms R2 2021\Bin40 It is expected to be the correct version 7.0.0.0.  

 

 

Below is the error.  I had removed all the references and was trying to add them back through the configure project extension vs 2019 and vs 2022 threw the same error. 

 

An error occurred while running the wizard.

Error executing custom action Telerik.WinControls.VSX.Actions.UpdateReferencesAction: System.Runtime.InteropServices.COMException (0x80004005): This reference cannot be removed from the project because it is always referenced by the compiler.

When you want to do the Upgrade Wizard, the following error appears: Failed to execute command. System.IO.DirectoryNotFoundException: Could not find a part of the path 'c: \ users \ quinteju \ appdata \ local \ microsoft \ visualstudio \ 16.0_c92db9cd \ extensions \ pfzn5mj3.wxk \ ProjectManagement \ Upgrade \ ScenarioDefinition.xml'. at System.IO .__ Error.WinIOError (Int32 errorCode, String maybeFullPath) at System.IO.FileStream.Init (String path, FileMode mode, FileAccess access, Int32 rights, Boolean useRights, FileShare share, Int32 bufferSize, FileOptions options, SECURITY_ATTRIBUTES secAttrs, String msgPath, Boolean bFromProxy, Boolean useLongPath, Boolean checkHostPath) at System.IO.FileStream..ctor (String path, FileMode mode, FileAccess access, FileShare share, Int32 bufferSize) at System.Xml.XmlDownloadManager.GetStream (Uri uri, ICredentials credentials, IWebProxy proxy, RequestCachePolicy cachePolicy) at System.Xml.XmlUrlResolver.GetEntity (Uri absoluteUri, String role, Type ofObjectToReturn) at System.Xml.XmlTextReaderImpl.OpenUrlDelegate (Object xmlResolver) at System.Threading.CompressedStack.runTryCode (Object userData) at System.Runtime.CompilerServices.RuntimeHelpers.ExecuteCodeWithGuaranteedCleanup (TryCode code, CleanupCode backoutCode, Object userData) at System.Threading.CompressedStack.Run (CompressedStack compressedStack, ContextCallback callback, Object state) at System.Xml.XmlTextReaderImpl.OpenUrl () at System.Xml.XmlTextReaderImpl.Read () at System.Xml.XmlLoader.Load (XmlDocument doc, XmlReader reader, Boolean preserveWhitespace) at System.Xml.XmlDocument.Load (XmlReader reader) at System.Xml.XmlDocument.Load (String filename) at Telerik.VSX.WizardEngine.Configuration.ScenarioDefinition.Deserialize (String fileName) at Telerik.VSX.ProjectConfiguration.ProjectConfigurationTypeSelectorBase.GetScenario (ProjectManagementScenarioPath path) at Telerik.WinControls.VSX.ProjectConfigurators.ProjectConfigurationTypeSelector.ProjectUpgrade (IPropertyDataDictionary additionalPreWizardData) at Telerik.WinControls.VSX.ProjectConfigurators.StreamlinedProjectConfiguration.StartUpgradeWizard () at Telerik.WinControls.VSPackage.CommandExecutor.Execute (UInt32 commandId) at Telerik.VSX.VSPackage.PackageBase.CommandCallback (Object sender, EventArgs e) 

 

I already reinstalled three times and it doesn't work in any way.  :(

 

Currently, adding a standard MS Form also shows the .vb extension. However, adding a RadForm shows only the name which may lead to incorrect name of the form as it is demonstrated in the attached gif file:

When Telerik UI for WinForms / WPF extensions are installed, Visual Studio is unresponsive for a couple of minutes after a solution is loaded. During that time, "Updating source control status…" is shown.

Workarounds:

• Disable Telerik UI for WinForms / WPF extensions.
• Checkout the solution file.

When there is empty folder under "%appdata%\Telerik\Updates" the WinForms Upgrade wizard fails with

We can update our extensions to honor the ImplicitUsings settings set globally for new projects. For the item templates, we will need to also check the project settings.
