Postback Persistence example doesn't work

Jun 9, 2009 at 10:15 AM

As I need to get the user modified zoom level and map position from code behind, I looked at http://googlemap.artembg.com/map/PostbackPersistence.aspx but it doesn't work. I tried with IE8, FF3 and Chrome but map is always at the same default position/zoom level regardless if I press save, submit or restore.

 

Any ideas?

I'm looking into this deeper and I'm "quite" confused!

The PostbackPersistence doesn't work if I run it from http://googlemap.artembg.com while it runs fine if I run on my VWD localhost (??!!)

However, my problem is different: I read a lot of old posts here and it looks like that having the control inside an update panel has always created probs, unfortunately it is what I need.
I looked into the "Inside UpdatePanel" example and it confirms my initial thoughts: if you put the control within an updatepanel when a postback fires, .zoom and .lat/lng do not contains the correct info but the "default one" (the one at initialization). 

I have already done most of the work to convert my app from subgurim to this control and, before giving up and get back to old sources, I'd really like to hear if there's a workaround for this. 
I need the map/control to be inside an updatepanel and at postback I need to get the zoom and lat/lng.

P.S. I tried to look into sources to find a fix without much success.

Suggestions? :(

Hi,

I just checked in the source with improvement of the postback persistence.
You can find it under Source Code (Change Set 33453) and build it.

However, I hope to be able to issue next release in next couple of days, where those changes will be included.

Ciao,

thanks! I downloaded the 33453 sources and built the dll (4.0). However it looks like the bug is still there, if the control is inside an updatepanel .zoom & C are set to original state. I'll try again when you issue the next release.

Hi,

I have the same problem too...The bug is still there...How can I insert the control into an Update Panel?

Thanks

It looks like the problem is not limited to having the control within an updatepanel but also have both in the same page, see http://googlemap.codeplex.com/Thread/View.aspx?ThreadId=61693

Hi Velio,

Is there any update to this?

Oct 25, 2009 at 8:50 PM

Hi Mark,

There is no update currently to that.
I hope soon to find some time to work on that and some other issues.
