Release 2024.1.312

Setting the DataSource in the SelectedIndexChanged event will trigger the event again. Thus leading to StackOverflowException. 

A possible workaround will be to unsubscribe from the event when changing the DataSource property or raise a flag which can be checked in the event handler.

Release 2024 Q1 (2024.1.130)

StackOverflowException is thrown when setting SelectedValue in the SelectedIndexChanged event.

To workaround this we can unsubscribe from the event before setting the SelectedValue property and then subscribe again. Another approach is to change the SelectedIndex property in the SelectedIndexChanged or SelectedValue in the SelectedValueChanged event.

There is still an issue related to the drop down auto complete described in this bug report.

https://feedback.telerik.com/winforms/1468737-raddropdownlist-autocomplete-mode-works-only-the-first-time-afterward-i-can-only-type-1-character

 

After downloading the Release R2 2020 SP1, we can now enter more than 1 character. However, if the user keys the space bar the text in the edit area of the drop down is deleted. Additionally, if the first 2 characters are the same (for example AA), the second character is never added to the text. The issue can be re-produced using the same steps as the linked post. I have also attached a screenshot.

 

Let me know if you need any additional info.

Release R2 2020 SP1 (LIB 2020_2_603)

I created a simple project just with a dropdownlist. The data source of the dropdownlist is a reader from SQL. First time, when I type something in the text area of the dropdownlist, the autocomplete works perfectly: if a type "235", it brings me at the first job starting with '235' and I can select the job. After, when I click back in the text area to type something else (for example: "236"), I can just type '2'. It won't let me type anything else and the autocomplete is not working. The autocomplete mode is Suggest.

This is a new problem with telerik 2020.2.512.40. Just previously, I had the trial version (2020.1.218.40) and it was working without problem. I didn't change anything in the small project. In fact, I took this project and put Telerik.Wincontrols.UI version 2020.1.218.40 anf it was working properly. I put back the version 2020.2.512.40 of the control and the problem reappeared.

 

First time (works fine):

 

Seconf time: not able to type more than 1 character
