Telerik UI for WinForms controls used to be automatically added to Visual Studio's Toolbox during the installation process when using .NET 2.0 (up to 4.8) Framework in your project. This means that the Toolbox population relies on the Telerik WinForms version available in the Global Assembly Cache.

With the introduction of .NET Core/.NET 5 and the WinForms designer, the Toolbox configuration doesn't rely on the GAC anymore and it is not necessary to have an installation of the Telerik UI for WinForms suite. The Toolbox version depends on the installed NuGet package:
https://docs.telerik.com/devtools/winforms/core/core-toolbox-version

There is a known issue that any UserControls/ custom controls don't show up in the toolbox for a VB  project with .NET6.  Even the RadControls are not loaded in the toolbox. 

This seems to be a known issue introduced in Visual Studio 2022 17.3 only for VB project with .NET6. Microsoft are currently working on the issue and I believe that an update will be introduced with the fix: https://developercommunity.visualstudio.com/t/Custom-and-User-Controls-not-shown-in-To/10118197 

Only users that have Telerik installation version 2021.1.122 are affected.

Symptoms:

Clients that have Telerik installation version 2021.1.122 can not build successfully .NET Core/.NET 5.0 projects. The following error occurs while compiling the project:

The problem is a missing NuGet fallback folder.

Solution:

You should create the missing ToolboxNuGetPackages folder in the installation folder of the controls, usually at C:\Program Files (x86)\Progress\ToolboxNuGetPackages.

Hi

How to remove or edit "Creator Telerik PdfProcessing" text before exporting DGV to pdf from PDF Properties.

I use telerik UI for WinForms project(not WPF) How to prevent auto close of RadContextMenu when user clicks on item on it? Now, after mouse click on any item, it closes. In WinForms there is ContextMenuStrip.AutoClose property to prevent autoclosing. Is there analogue of the property on Telerik RadContextMenu?

Hi,

I am trying to create a PDF Table but I  am missing one or more libraries that I should reference. The code fragment I am trying is as follows:

Table table = new Table(); 
TableRow firstRow = table.Rows.AddTableRow(); 
TableCell firstCell = firstRow.Cells.AddTableCell(); 
Block block = firstCell.Blocks.AddBlock(); 
block.InsertText("Testing"); 
Thanks

I hava a model that contains IsSelected Property, and I want to bind the row IsSelected of gridview to that IsSelected, what should i do?

    public bool IsSelected { get; set; }
}

private BindingSource _bindingSource;
private List<MyClass> _myClassList;
private RadGridView _gridView;

private void DataBinding()
{
    _bindingSource = new BindingSource { DataSource = _myClassList };
    // how to bind _gridView.Rows.IsSelected to _myClassList.IsSelected?
    _gridView.DataSource = _bindingSource;

Hello,  I am adding a 15mb image to the background of a RadDiagramShape.  The problem I am running into is the RadDiagram eats up 1gb of memory every time I open the form.  Eventually if I don't call GC.Collect the Image.FromStream blows up due to a memory limit.  I have traced it back to the RadDiagram utilizing a ton of memory.  The question I have is what performance considerations should I be looking at with the control?  I included the steps I am taking to add in the image.  

Thanks in advance!
Brian
