I am attempting the following:
1 - Default.Master with no ScriptManager in it.
2 - Default Level 1.Master based on Default.Master still with no ScriptManager in it.
3 - Tracks.Master with Script manager, UpdatePanel and a Timer as the trigger.
4 - Create Tracks.aspx based on Tracks.Master.
5 - Create TracksAndVHFs.aspx based on Default Level 1.Master
6 - On TracksAndVHFs.aspx add iFrame which displays Tracks.aspx page.
Cannot unregister UpdatePanel with ID 'upTracksAndVHFs' since it was not
registered with the ScriptManager. This might occur if the UpdatePanel was
removed from the control tree and later added again, which is not
Parameter name: updatePanel
When attempting to edit the Tracks.aspx page.
I came across:
but unsure how I can implement this in my case.
Any help would be appreciated,
Just a quick further note: This only happens when I access the page in edit mode. When I view the page it works fine. Si I just need to somehow disable the whole AJAXing thing when editing the page maybe.
