Hello loretta242,

I have created and attached a sample to demonstrate how to achieve this. Using the client side ItemExpanded event of the WebExplorerBar I gain access to the child items of the group that was expanded and get the anchor element of the last child. After you have the anchor element you can use focus or scrollIntoView to show the newly expanded items.

Please let me know if you have any questions concerning this matter.

Hello Lorettac242,

I am following up to see if this issue is resolved.

 If this isn’t the case please let me know if I may be of further assistance with this matter.

Hello lorettac242,

I have modified my sample to have up to 3 levels of items in the WebExplorerBar. I am unable to reproduce the behavior you are experiencing. When I expand an item if the item has children that would expand beyond the bottom of the page they are scrolled into view using either the scrollIntoView or focus functions.

I have attached the sample project I used to test this.  Please test this project on your PC; whether or not it works correctly may help indicate the nature of this problem.

If the project does not work correctly, this indicates either a problem possibly specific to your environment, or a difference in the DLL versions we are using.  My test was performed using version 11.2.20112.1019 in NetAdvantage for ASP.NET 2011 Volume 2.

If the project does show the product feature working correctly, this indicates a possible problem in the code of your application.  It will help if you can provide a small, isolated sample application that demonstrates the behavior you are seeing.

Or, if this sample project is not an accurate demonstration of what you're trying to do, please feel free to modify it and send it back, or send a small sample project of your own if you have one.

Hello lorettac242,

I have looked further into the sample and if when you call scrollIntoView you pass in false instead of true it will scroll the last item in the expanded item to the bottom of the screen instead of the top. This may help some with the jumping. In theory another way you could do this is if you can find the scroll position you can edit the scroll position over time to make it a smoother scroll.

As for having an expand behavior for item in the group this has been determined to be a feature request. I have logged this as a feature request FR13909. In theory you could also achieve this by looping through all the items in the group and making sure only one is expanded.

Please let me know if I may be of further assistance with this matter.
