I have been battling a problem recently with RadAjaxManager.

I have a RadButton that opens a RadWindow using AJAX (calls a postback that set's VisibleOnPageLoad=true). But any button in the window that was open won't make it's postback through ajax. Instead it makes the request through a normal postback. If I set the RadButton to do a normal postback (not setup an ajaxsetting for it) then the buttons in the RadWindow work.

Any ideas on what I am doing wrong? I have tried searching the form and google to find a solutions and can't find anyone else that is having the same problem.

I have included the parts of code that are related to the problem (i hope)... thanks in advance.

Hi Paulo,

In the Joshua's case I suggested to try to add the RadWindow into always visible asp Panel and add that Panel into the RadAjaxSetting instead of adding the window itself. Also note that it is not correct to set inner for the RadWindow controls to update its parent Window. So I would also suggest instead of the last Ajax settings to add a setting in which the mentioned asp Panel updates itself.

Hi ,

By this : " Also note that it is not correct to set inner for the RadWindow controls to update its parent Window", I meant that controls added in RadWindow ContentTemplate for example could not be set as ajax initiator to update their own parent RadWindow. The problem in the case that was discussed here was that invisible control was added in the RadAjaxManager settings which is not a supported scenario, therefore usage of always visible container was suggested.
If your case is not the same and you are still facing issue in using RadWindow with RadAjax I would suggest you to open a regular support ticket and describe your exact scenario there. Therefore we will be able to better track the problem and do our best to provide proper solution.

All the best,

Thank you for taking the time to reply, but I have already worked out a viable solution to using the RadWindow in the scenarios I was hoping to. Basically I just put a placeholder in the window and dynamically load controls into it. The issue was getting the window to show up using code behind so i just registered a startup script during the async postback even handlers to show it (and size it). I use the RadAjaxManager to hook up any buttons/grids or anything that I want to use to async the loading of the placeholder. It can be quirky (if I use more than one window and try to recreate the placeholder strategy: for instance a radwindow on a master and on individual pages), but is working well enough.
