I used the UpdateControls property to just update the WebTreeView control within the WebFlyPostBackManager control and this didn't resolve the issue where the WebTreeView/WebCombo control wasn't functioning as expected. Given this, I am still afraid of what other side effects exist.=

I also noticed that other ASP controls on the page don't function as expected any more. I have other buttons that use an UPDATE PANEL to update various forms of UI. With the WebFlyPostBackManager used within the user control described above, the ASP controls that should use an UPDATE PANEL to make an AJAX Call now do a full postback. This is not an issue if the WebFlyPostBackManager is removed.

Is there an issue with using a WebFlyPostBackManager and an UPDATE PANEL in the same page? The WebFlyPostBackManager is set to just update the WebTreeView being updated. I don't see how they would conflict. It would be nice if the WebTreeView not being updated within an UPDATE PANEL bug is fixed to avoid these conflicts.

EDIT:

I replaced the WebFlyPostBackManager with an UPDATE PANEL and the performance increase is tremendous. Also, the issue with the WebTreeView/WebCombo control is resolved. Unfortunately, there is a rendering issue with the "Loading" text. This seems to be the way to go given it's much more stable and the performance is acceptable. What rendering issues did you notice in your previous test of using an UpdatePanel to update the WebTreeView?

Have you set correctly the WebFlyPostBackManager settings? Besides ServerURL, you also need to declare WebFlyPostBack object at the server page (.cs).

e.g

Please take at look on my sample. You should be able to find it.

Yes, an instance of the WebFlyPostbackListener was added to the UserControl. I didn't set the ServerURL because the control is reuseable so this reference will change from page-to-page. I tried setting it to the *.ascx but I kept getting the "There is no content returned from server side. Most likely cause is server time out." message. I do not get the message if I do not set the ServerURL property. Moreover, it does seem to work, however, the other WebTreeView/WebControl on the page doesn't open when clicked.
To summarize, I have a user control with a WebTreeView and a WebFlyPostBackManager that refreshes it self after a button click. These user control is used on other pages that also contains a WebTreeView/WebCombo control as well as other controls. Aside from being very slow, it does function as expected. The issues are that I tomtimes get the "There is no content ..." message and the WebTreeView/WebCombo control does not open when clicked.

Code within User Control:
<ISWebDesktop:WebFlyPostBackManager runat="server" ID="wfpbmPortNav" EnableUIMode="True">
<FlyPostBackSettings PostControlState="True" PostHiddenFields="True" PostInputControls="True" PostViewState="True"> </FlyPostBackSettings> </ISWebDesktop:WebFlyPostBackManager>
private WebFlyPostBackListener _listener = null; // WebFlyPostBack Listener
WebFlyPostBackListener _listener = null; // WebFlyPostBack Listener
/// <summary>
<summary>/// Handles the page's Init event /// </summary> /// <param name="sender">Sender</param> /// <param name="e">Event arguments</param> protected void Page_Load(object sender, EventArgs e)
{
// Initialize WebFlyPostBackListener this._listener = new WebFlyPostBackListener(this.Page);}
I already showed both of my samples with using UserControl or without it but no issues. Maybe you are missing something. It would be easier if you can send me your simple working sample for me to investigate it.

Your example does not duplicate my scenario. It's two user controls with the WebTreeView/WebCombo in one and the WebFlyPostBackManager in the other. Also, the ASPX page is setting various WebTreeView/WebCombo properties. In my scenario, everything is self contained within a user control. Furthermore, ANOTHER WebTreeView/WebCombo exists within the ASPX page. That is the control that does not work as expected (i.e. does not open when clicked).

It depends on the context. But it would be better if you can show us the prove so we can analyze it for you.

It would be nearly impossible for to give an example for various reasons. It would be easier if the WebTreeView/WebCombo was updated via an UPDATE PANEL without issues. You confirmed in this thread that it is an issue. Is this currently being fixed?

I have a WebTreeView that may or may not be using LoadOnDemand. I need a way to refresh the WebTreeView with different content after the a WebButton has been clicked.

The problem is that the WebTreeView doesn't seem to update itself even though the logic adds different nodes. How do you force the WebTreeView to rerender?
