Type: Bug Report

Kendo Inputs changed values are not restored when a page is redisplayed

Steps to reproduce

Execute the code below
Enter some values in the Html and Kendo inputs
Hit the browser's back button
Hit the browser's forward button to redisplay the page

Current Behavior

The value in the Html Input is restored but not the value of the Kendo Input. The same behavior applies for Kendo NumericTextBox, etc.

      <div>
        <label for="KendoInput">Kendo Input</label>
        @(Html.Kendo().TextBox ().Name ("KendoInput"))

Hi Stoyan,

Ok, I understand that the structure of telerik ui editors do not permit this behavior. Thanks for your reply.

As a side note, a refresh is equivalent to a GET whereas Back and Forward are equivalent to a GET + an Update from the browser's cache (as far as the latest chromium browsers are concerned). Back and Forward do go back to the server, easily demonstrated by a breakpoint or the display of a counter.

Hello Netty,

This behavior is observed because when you hit 'back', the browser reloads the page as it was for your last POST to that page or your last 'GET' from that page. Please review the following stackexchange thread for more information.

Regular inputs are included in this but Telerik UI Editors aren't because of the way they are structured and wrapped. That being said the regular inputs aren't persistent either since the behavior you refer can be observed only when navigating back and forth to the page, but not when the page is refreshed, etc.

I hope this information is useful.

Ok Stoyan, no problem.

However, please notice how the value of HtmlInput is restored while KendoInput remains empty.

Hello Netty,

The reported behavior is expected. To persist a value entered in an input by the user you would need to either use cookies or data persistеnce.

That being said this concept is valid across the web and isn't exclusive to Kendo and Telerik UI.

If you need further assistance with the set up of your application I would recommend our Professional Services.
