Learn about a new feature in Telerik Reporting that lets you change the default parameters editors types for visible parameters in the HTML5 Viewer's Parameters Area.

The Telerik Reporting team works hard to satisfy your needs and wishes. With every release we are trying to improve our products and to offer you helpful new additions. In our latest release, the Telerik HTML5 Report Viewer provides an option for changing the parameter editors type. All newly added editors are  Kendo UI widgets since the HTML5 Report Viewer is built on top of the Kendo UI product.

Defining the Parameters

The UI editor can be changed for parameters both accepting single or multiple values. The parameter needs to have predefined AvailableValues in its report definitions. To specify that the parameter should accept multiple values turn on the MultiValue property.

Defining the Editors Type

Both parameters have two optional editor types – ListView and ComboBox. The listview is the default editor type. To use it there are no additional settings to be configured. As for the other editor type, a simple setting must be applied to the HTML5 Report Viewer:

First, this feature requires the latest official release. So please consider updating to R1 2019+.

Second, after we are all on the same page, for your convenience here is an example for all HTML5 Report Viewer wrappers:

   editors: {
       singleSelect: telerikReportViewer.ParameterEditorTypes.COMBO_BOX,
       multiSelect: telerikReportViewer.ParameterEditorTypes.COMBO_BOX

 Editors = new Editors {
       SingleSelect = EditorTypes.ComboBox,
       MultiSelect = EditorTypes.ComboBox
