Problem with MultiValue parameter on HTML5 Webform Viewer

[Terry]

The MultiValue drop-down/list is not working correctly. We are using version 18.0.24.130.

If you select all values, it works correctly except the values are not highlighted to indicate they are selected. 

If you select individual values on a required parameter, the message "Please input a valid value" does not go away and the Preview button remains disabled. If you select individual values on a non-required parameter, they are properly highlighted, but when you click Preview, the report ignores them / does not use them to filter the results.

This happens for every report, regardless of who develops it, wherever the multi-value parameter is used. 

Our sites using  15.2.21.915 does not have this issue. 

Thanks!

Hello Terry,

I tested with our sample project CSharp.NetFramework.WebFormsIntegrationDemo and the report 'Product Line Sales.trdp', which contains a MultiValue parameter. It worked as expected.

Is the issue reproducible with the same example on your end? The sample gets deployed with the installation of the product, by default in the folder 'C:\Program Files (x86)\Progress\Telerik Reporting 2024 Q1\Examples\CSharp\.NET Framework\WebFormsIntegrationDemo'.

Which Kendo jQuery version do you use? The minimal required is 2022.3.913 - HTML5 Report Viewer Dependencies.

Do you use custom styles in the viewer?

You may consider opening a support ticket and sending a runnable project replicating the issue for local investigation.
