RadMultiColumnComboBox Populating Value While Visibility = Collapsed causing extra text

[Tyler]

Hello,

I am dealing with a minor bug on my pages that have a hidden panel that I show when adding new items. It shows the selected item, but also includes the text afterwards. It only happens when the dropdown visibility is collapsed. When I am populating the dropdowns I have tried setting  AutoCompleteProvider.SearchText = string.Empty and AutoCompleteProvider.MatchText = string.Empty and setting the panel to visible and then populating the value, but I cannot figure out how to clear out the text. What is a good work around for this bug. 

 I have attached an example project. To replicate my issue click "Populate Dropdown" then click "Toggle Visibility". If you toggle visibility before populating the issue will not occur.

Hello Tyler,

I have tested the sample project using our latest assemblies version (which is 2023.1.315) and I was not able to observe the mentioned behavior. The following gif shows the result that is present on my end:

On a side note, we had a similar scenario where two items were displayed (the same result as in the Capture.png) when the theme was changed at runtime. A fix for this came with the 2022 R3 release.

With this being said, may I ask if you could update to the latest version of our assemblies and see if this behavior is still present?

Yes I will try that. Also it is worth mentioning it only happens the first time you populate the combo box while it is hidden. Any time after that it works as expected.

Please let me know if this behavior is still present when using the latest version of our assemblies.

Updating resolved the issue. Thank you!

I am happy to hear that updating to a later version has solved this issue and that you took the time to let me know.
