Could you please give us a step-by-step guide or a running simple sample that we can use to observe the problematic behavior?

WebFlyPostBackManager Refresh WebTreeView Error

Hello,

Actually I don't need the random logic.I just want to show different data in refresh. If I don't use random logic,the rendering process is also slow.In my opion, it seems Webpanemanager or usercontrol cause the problem.In a single page, the process of rendering a webtreeview in a webpanemanager will not cause the problem.

Regards

I made a minor modification to your sample in order to resolve the issue. The changes are listed as follow:

Remove WebTreeView out of the ASP:Panel control.

Original code (WebForm1.aspx)

...
<asp:Panel ID="Panel1" runat="server">
    <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
    <ISWebTreeView:WebTreeView ID="WebTreeView1" AllowMultipleSelect="false" runat="server"
        Height="500px" Width="400px">
    </ISWebTreeView:WebTreeView>
</asp:Panel>
...

Modified code (WebForm1.aspx)

...
<asp:Panel ID="Panel1" runat="server">
    <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</asp:Panel>
<ISWebTreeView:WebTreeView ID="WebTreeView1" AllowMultipleSelect="false" runat="server"
    Height="500px" Width="400px">
</ISWebTreeView:WebTreeView>
...

Enable RequiresUIRefresh property and add RefreshModifiedControls() method.

Original code (WebForm1.aspx.cs)

...
WebTreeView1.ExpandAll();

uiService.ClientAction.UpdateViewState();
uiService.ClientAction.RenderControl(Panel1);
...

Modified code (WebForm1.aspx.cs)

...
WebTreeView1.ExpandAll();

uiService.ClientAction.UpdateViewState();
WebTreeView1.RequiresUIRefresh = true;
uiService.ClientAction.RefreshModifiedControls();
uiService.ClientAction.RenderControl(Panel1);
...

This should helps. Please have the changes tested on your end and let us know whether it helps or not.
