I thought I had already replied to this, but apparently my reply didn't save properly...
Enable Partial updates is currently disabled. We have tried both options of the 'Supports Partial Rendering' option in the module control settings with no discernible difference.
The version of the editor doesn't seem to matter. We're seeing the same issues in several versions of DotNetNuke 5 and 6. I am compiling the module against vesoin 5.4.4 of the DotNetNuke.dll.
To be very clear, this problem is on a control that loads on a new page, not on the main module display. This is the ModuleActions line that adds the link to the control with the problem:
Dim Actions As New Actions.ModuleActionCollection
Actions.Add(GetNextActionID, "Administration", "Administration", "", "action_settings.gif", EditUrl("Administration"), False, Security.SecurityAccessLevel.Edit, True, False)
Return Actions
There is also a dnn:textedit control on the Settings control as well, that works without issue, but it is not in an update panel.
Thanks for your assistance.
