[Solved] RadAjax manager and dynamically added controls

[andieje]

Hi

I need to add some hyperlinks to a page dynamically that trigger an synchonous postback using

javascript:__doPostBack

and the radajax manager. I reduced the page to its most simplest form but i can't get it to work - the page performs a full postback when the link is clicked

I have created a panel that contains a placeholder. I am adding a hyperlink dynamically to the placeholder. The href property of the hyperlink is a javascript doPostback call. I have set up the RadAjax manager so that the pnl is the ajaxified control and the updated control is the pnl but this did not work - a full postback was performed (my thinking here was that is i set the pnl as the ajaxified control then any control within the panel such as my dynamically link that triggers a postback will lead to an asynchronous update of the panel itself). I also tried adding the dynamically created hyperlinks to the ajax manager in the code behind but that didn't work either. Please can you advise what I need to do.

many thanks

Hi andieje,

Please try setting the HyperLink Id to "x" and see if it works this way.

Note that the first argument of the _doPostBack() method should be the UniqueID of the control initiated the postback.

I hope this helps.
