Steps:

1. Go to Telerik Web UI MultiColumnComboBox WebForms MultiColumnComboBox Overview Demo | Telerik UI for ASP.NET AJAX

2. Enter "ha" select some records

3. Click out of the dropdown to close it

4. Textbox keeps "ha" but the message below reads that You have selected Thomas Hardy whose ID is AROUT. They are a Sales Representative at Around the Horn however, nothing has been selected.

Is it expected ?
If it's a bug and having a long cycle to fixing bugs could you recommend any workaround?

Bug is still there after releasing Telerik UI for ASP.NET AJAX 2024.2.513 (2024 Q2)

Please fix it as soon as possible. This powerful control is quite useless now.

to clarify: it's not fixed in your demo website so I'm not sure if it uses the latest version

Hi Michael,

After further investigation, we concluded that this is not a bug, but the intentional behavior of the MultiColumnComboBox control - this is the feature that highlights the first item as soon as the DropDown is opened.

If you want to remove it entirely, you can turn it off by adjusting the HighlightFirst property:

<telerik:RadMultiColumnComboBox runat="server" ID="RadMultiColumnComboBox1"  HighlightFirst="false" />

As for the NuGet package, here are a few tips on how to find it:

  • Search for Telerik.UI.for.AspNet.Ajax in the Visual Studio Nuget Manager -> the Telerik NuGet option should be selected in the Package Source dropdown on the right side:
  • Verify Credentials: Double-check that the credentials you are using are indeed correct. Consider resetting your Telerik account password to ensure there's no issue with the credentials themselves. Also, check for any special symbols in the password as explained in this article: Error 401 Unauthorized.
  • Remove Saved Credentials and log again: Remove the saved credentials from your Windows by following the steps at https://docs.telerik.com/blazor-ui/troubleshooting/nuget-feed#removing-saved-credentials. Upon removal, log in again.
  • Clear NuGet Cache: Sometimes, the NuGet cache might cause issues. Try clearing your NuGet cache through Visual Studio or by using the command line with nuget locals all -clear and then attempt to restore the packages again.
  • NuGet Config: Ensure that your NuGet configuration file is correctly set up to use the V3 URL and that it includes the correct credentials. You might need to manually update the NuGet.config file to include the updated source and credentials.
  • Visual Studio Version and NuGet Package Manager: Since you're using Visual Studio 2022, ensure that your NuGet Package Manager is up to date. Older versions might not correctly handle the V3 feed.
  • Install Telerik.UI.for.AspNet.Ajax.Net NuGet Package from a local folder - https://docs.telerik.com/devtools/aspnet-ajax/knowledge-base/common-local-folder-nuget-server

Kind regards,
Vasko

Thank you Vasko, HighlightFirst="false" helped.

As per nuget, nothing has helped - the latest available version is still 2024.1.31.
I noticed that even in your screenshot the latest version is 2024.1.31 too and there is no ver. 2024.2.513

Finally, we figured it out - for that release we have to use another package "Telerik.UI.for.AspNet.Ajax.Net462" - not .Net45

Thanks for help.
