Visual Studio Conversion tool not appearing in menu

hi I'm running visual studio 2019, with Telerik Winforms UI 2019.2.508.40

I'm trying to convert an existing VB project to Telerik controls, but I don't see the menu option for the converter tool. (Under Extensions->Telerik->Telerik for WInforms, I see a bunch of options: Configure project, AddRad** References, and AddRad** Forms, but no option to convert. (In a new or existing project)

I have read this thread: https://www.telerik.com/forums/convert-your-existing-application-to-telerik-ui-for-for-winforms-does-not-work

with no luck.

I have tried adding the Telerik Winforms VsExtension through the Extention manager but it is not showing anywhere that I can find as an option to install.

Running
C:\Program Files (x86)\Progress\Telerik UI for WinForms R2 2019\VSExtensions\VS2019\Telerik.WinControls.VSPackage.vsix
reports that:
"This extension is already installed to all applicable projects"

Any ideas? Thanks,

Encrypted PDF-Files in PdfViewer

Is there a way to display an encrypted file in PdfViewer ?

I created a file:

formatProvider = new Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.PdfFormatProvider();
formatProvider.ExportSettings.UserPassword = "xxx";
formatProvider.ExportSettings.IsEncrypted = true;

formatProvider.Export( ...)

And now I want to display it, but haven't found a place to pass a password to the viewer.
It's not displaying any error, it's just displaying - the correct number of - empty pages.

Substring function in RadGridView column expression

Hi there,

I've been tasked with migrating DataTable functionality to Telerik RadGridView in a C# WinForms app.

DataTable code sample:

   var taxColumn = new DataColumn();
   taxColumn.DataType = System.Type.GetType("System.String");
   taxColumn.ColumnName = "tax";
   taxColumn.Expression = "SUBSTRING('ABC',2,3)";

My attempt to do the equivalent using a RadGridView TextBoxColumn fails with "unknown function SUBSTRING()".

Is there any similar functionality in RadGridView to the Substring function in DataColumn please? It's essential to be able to write expressions that do substirng operations in the app I'm working on.

Thanks as ever for your help!

Kind regards, James

Read only OpenFolderDialog

I am happy Telerik created these dialogs for aesthetic reasons.

Is there a way to restrict access to file operations (Delete, copy, et. al.)?? I want to restrict file functions that can be performed via these dialogs. For example, I want to prevent someone from copying files from a USB when selecting a folder or selecting a file.

Thanks,

Jim
