Released: Nov 12, 2025

Updates in v2.3.15

Features

File Upload: Limit the Number of Uploaded Files

• This update adds a new maxFiles property to the File Upload question type. You can use this property to specify the maximum number of files a respondent can upload. By default, the limit is 1000 files. The maxFiles property takes effect only when allowMultiple is set to true.
• In Survey Creator, you can configure the same behavior using the Maximum number of files editor. This setting becomes available when you select the Enable multiple file upload checkbox.

Fixes

Form Library

• Dragging the thumb of the second slider is not smooth when a survey includes two sliders.
• Dynamic Panel: Expression validator didn't display an error message if checkErrorsMode is set to "onValueChanged".
• Single-Line Input was case-insensitive.
• Image Picker: Word wrap doesn't work for image captions.

Survey Creator

• Cannot select and copy survey UI texts in the Preview tab.
• "Survey" toolbar button and "Open settings" question adorner remained available when the Property Grid is hidden.
