Dynamic control not working properly with radajax manager

[andieje]

Hi

I have created a really basic page with a panel that contains some content and a dynamically created link button. When the link button is clicked the panel is updated. The update is supposed to be done by a partial postback using the radajaxmanager but, for reasons I don't understand, every other time the link button is clicked a full postback is performed rather than a partial postback. In other words i get one partial postback then one full postback and so on.

I have reduced the page to its bare bones below. Please can you tell me how I fix this.

Hello Andieje,

Try setting ID of the Label control before adding it to Controls  collection of the place holder.
This should help.

All the best,
