One with the "Old" count and one with the "New" count.<BR/><BR/>My implementation of this is inserting records into a database in one particular situation and I'm ending up with two record inserted because of the what I explained above.<BR/><BR/>Can you help? How would you suggest I isolate the first vs the second postback?<BR/><BR/>Thanks!Scottynoreply@blogger.comtag:blogger.com,1999:blog-171924705653813582.post-11424287849792556622007-08-16T01:57:00.000+03:002007-08-16T01:57:00.000+03:00Hi, it's me again, first I want to say thank you cuz I already implemented the dynamic user controls with your help,<BR/>now I'm facing another problem and I want to see if you can help me.<BR/>I have some User Controls and them will be populated from different web services, each one of the web services has its own response time.<BR/>I need to load the screen as fast as I can, also users don't want to wait until the entire data is pulled to see the page, so I need to start showing the controls on the page as soon as I get them populated from the web services.<BR/>what I did was to create threads for each one of the web services calls, in that way I can call all the web services at the same time and start receiving data to populate the user controls.<BR/>I'm doing this when the page loads. The user controls are inside an update panel.<BR/>The problem is that the page doesn't show anything until the page load event finishes. I tried with response.flush() method with no luck, also I've tried to manually update the panel content each time a single thread finishes using the UpdatePanel1.Update() method but I'm still not luck.<BR/>Also sometimes, the page loads but user controls are not populated, usually the ones that belong to the second or third threat.<BR/>hopefully you have faced something similar before and you can help me with it.Andres Vnoreply@blogger.comtag:blogger.com,1999:blog-171924705653813582.post-73072470658186273362007-08-03T22:58:00.000+03:002007-08-03T22:58:00.000+03:00See my post about <A HREF="http://couldbedone.blogspot.com/2007/07/dynamically-created-controls-dynamic.html" REL="nofollow">"dynamically created controls: dynamic rows sample"</A> in this blog. You need to load your controls into the placeholder on each postback.Yuriy Solodkyyhttp://www.blogger.com/profile/04926659302956943479noreply@blogger.comtag:blogger.com,1999:blog-171924705653813582.post-81245774260668845932007-08-03T19:55:00.000+03:002007-08-03T19:55:00.000+03:00I've created user controls in the way you suggested and they are created fine. The problem I'm facing is when trying to create more than one control, in other words, I have a page with a button, every time the button is pressed I would need to add an user control into the update panel (inside a place holder or table within the update panel). This is not working, because every time the button is pressed the controls are missed, so I always have one control created. How can I preserve the controls created between async post backs? hope this explanation is clear enough.Andres Vnoreply@blogger.com
