TaskBoard and RadFilterView missing from toolbox

[Martin Hamilton]

I don't see TaskBoard and RadFilterView in the toolbox even though it says it's in the latest release.

Is it only for .Net 5 and above - that doesn't seem to be mentioned in the documentation or release notes.

If it can be used in .NET 4.x - how can I manually add them to the toolbox?  What .dll to I use to add them?

I added them manually... I guess there was a glitch in the matrix when the latest telerik version was installed.

Hello, Martin, 

I am really sorry to hear that you are experiencing any problems with the toolbox items for RadTaskBoard and RadFilterView controls. They were indeed introduced in R3 2021 (version 2021.3.914):
https://www.telerik.com/support/whats-new/winforms/release-history/ui-for-winforms-r3-2021-(version-2021-3-914) 

It is expected to be available even if your project uses target framework 4.0:

When encountering such unusual cases, you can either reset the toolbox by right-clicking it and selecting the reset options from the menu or uninstall the existing Telerik version and install it again.

As you have already found out, it is possible to add controls to the toolbox manually. Additional information on this approach is demonstrated here:

I hope this information helps. If you need any further assistance please don't hesitate to contact me.
