I'm trying to drag and drop RadCallout to an existing Form Designer, and while I don't get any errors and it appears that it drags and drops, the control doesn't remain on the form and does not appear in the Components Tray either. I do not have a problem adding other Rad controls, but Callout doesn't seem to work. Will it only work with a Rad Form? Or is there a prerequisite I should know about? Do I need to install something so that the Designer can properly display it?
I'm using Visual Studio Professional 2022 version 17.5.5 with Telerik UI for WinForms Extension 2023.1.313.33.
Thanks in advance!

Hi REUVEN,
By default when the RadCallout is dragged from the ToolBox and dropped on the form, it should appear in the components tray as demonstrated in the RadCallout - Design Time. Can you check if it appears in the RadForm.cs designer file? Also, can you create a new form and try again the same steps? You can also try to close the VS, delete bin, and obj files in the project directory folder. Then load the project rebuild it and try again.
Give these suggestions a try and let me know how it goes.

Hi Dinko and Thank you for your advice!
I tried your suggestions, but unfortunately, none worked. Although I need to add RadCallout to my regular Windows Form, I also tried adding it to a new RadForm.cs with no luck. The control doesn't remain on the form, not in the Designer file, nor in the Components Tray.
I'm using Nuget to get the packages needed for runtime use of your Winforms components. Perhaps I need to install some other Telerik design tools?
Thank you!

Hi, thank you for following up! Its .Net Framework version 4.8.
As you suggested I created a new project and although I could not add RadCallout to a new Windows Form, I could add it to a RadForm. Does that mean RadCallout can only be placed into a RadForm, not into a Windows Form?
The RadCallout control can be successfully dropped from the toolbox into Form and RadForm. The following GIF file demonstrates the steps perform on my side. I am also attaching the sample project. Can you send me your test project to check if there is a difference in the settings?
