Incorrect Appearance or Errors Occur in Hidden Widgets
|Product||Progress® Kendo UI® for jQuery|
Hidden Kendo UI for jQuery widgets are rendered incorrectly or raise errors.
If you display widgets that have been in an initially hidden container, call their
resize() method after you show them. Initializing widgets on elements with the
style="display: none;" configuration might cause errors, such as inability to calculate dimensions and positions or even throw errors. The reason for this behavior is that such calculations are not available for elements that are not rendered by the browser.
Usually, delaying the widget initialization until after it is displayed resolves the issue and improves the page performance.
