Expanded Panelbar not working

[Kurt Kluth]

Unsure of how to fix the problem we currently are experiencing.  While running the project locally the PanelBar is expanded like we instruct it however when we publish it to production it no longer is expanded.  We have currently set all Panel items to be expanded.

I have included images to show what I am trying to accomplish (FullyExpanded).

Here is the snippet of code to show what would be displayed in the images.

Just tested this problem does not occur within Chrome.  Tried clearing cache.

Hi,

I am not able to see the actual issue in the uploaded images as they appear one and the same, although one is called "fullyexpaned" and the other is called "notfullyexpanded". I have inspected the snippet provided and I noticed two things that may confuse you and result in behavior that you are not expecting.

First, using a RadPanelBar with ExpandMode set to FullExpandedItem suggests that only one item is expanded at a time. You may check the RadPanelBar "Expanding and Collapsing Items" help article for further reference on that matter. If you would like to have all RadPanelBar items expanded at one and the same time, you should set ExpandMode to MultipleExpandedItems. You may test the ExpandMode options behavior on the Expand Behavior online demo.

Second, if clearing the browser cached information have resolved the issue observed, it is most probably connected to the RadPanelBar property PersistStateInCookie, which is set to True in your case. In this case, all changes you have done, while interacting with the RadPanelBar, are kept in a cookie and the RadPanelBar would be loaded in the way that is stored in that cookie. Clearing the cached data would have deleted that cookie and you were able to observe behavior as expected.

Upon testing your sample, I was able to observe that when the RadPanelBar is loaded initially, it has all items expanded - disregarding the FullExpandedItem specification as it is overriden by the hard-coded property Expanded="true". And when the page is refreshed, the RadPanelBar state is restored from the cookie, this time regarding the FullExpandedItem specification - only one item is expanded. Thus, following the ExpandMode specification and setting ExpandMode to MultipleExpandedItems would solve this misbehavior.

If these tips do not help you solve the issue faced, could you elaborate a little further on your issue and scenario?

Are there any further suggestions in an attempt to resolve the issue that we are facing?

Hello,

From the provided information in this thread, the desired functionality is to have a RadPanelBar, which acts in FullExpandedItem mode for the root items and in MultipleExpandedItems mode for the child items, which should be also expanded upon expand of the root item. In addition to this the state of the control should be persisted in a cookie. I have prepared a sample page where the expand mode is set to Multiple, and the root items are manually closed when another one is expanded. This behavior will work correctly with the functionality which persist the state in a cookie.
