DropDownList

I am using Visual Studio 2019, version 16.3.1 and when using the DropDownList and running it in the VS debugger, the DropDownList get populated properly, but when you click the down arrow for the first time, the list drops down and you can scroll with the mouse wheel, but it will not allow you to select anything with the mouse.

If you click the down arrow to close the list, and click it again to reopen the list, it works properly - selecting the item chosen.

I have tried numerous property setting in attempt to narrow down if any of the properties set are causing it, but have been unsuccessful.

I have created several test projects with only 1 form and only the dropdownlist on the form and this happens reliably in every project I have tested within Visual Studio.

If I build the executable and run it directly, the DropDownList works properly as expected.

The DropDownList version is listed as 2019.3.917.40 in Visual Studio 2019 16.3.1.

I opened the project in JetBrains Rider on the same machine and everything works fine.

Hello, Travis,

I am glad that the problem you were facing is not reproducible any more.

If you encounter any further issues in future, it would be greatly appreciated if you can provide a sample project demonstrating the undesired behavior together with detailed steps how to replicate the issue. This will significantly facilitate the investigation process.

If you need any further assistance please don't hesitate to contact me.

I am not really sure what the issue on my end was but I received a new workstation this week and after installing all of the development tools (VS 2019, Telerik controls, etc.) I am not seeing this behavior anymore from the dropdownlist.

I copied over the project I sent you and it works fine for me now as well.

I can't say whether installing a fresh copy of Visual Studio or the Telerik Controls resolved the issue, but nevertheless I am not seeing this any longer.

I apologize for any time spent on this as I should have tested it on another machine before reporting the issue.

Hello, Travis,

The provided sample project is greatly appreciated. 

I would like to note that using the mouse wheel will iterate through the items only if the DropDownStyle property is set to DropDown. In this mode, RadDropDownList offers a text box in the editable part that can handle the mouse input.

As to the selection when using the mouse, following the provided information in your initial post, I clicked the arrow to open the drop down for the first time and selected an item from the popup. The selection in RadDropDownList is successfully changed on my end. Please refer to the attached gif file illustrating the behavior on my end with the sample project and the specified version. Am I missing something? Do I need to perform any changes in the project? 

I am looking forward to your reply.

Sorry for the delayed response as I have been travelling at work.

I have attached my test project which demonstrates the issue.

Hello Travis,

I tested this case with the specified versions but I was not able to reproduce it. It works as expected on my end. This is why I want to kindly ask you to send me your test project that reproduces the undesired behavior. It would be helpful if you could add a short video that shows the issue as well.  

Thank you in advance for your patience and cooperation.
