Hi,
I'm playing around with various scenarios using the RadControls and was wondering how the following would be achieved:
There are three controls on a page: a button, a drop-down list, and a textbox.
Selecting a value from the drop-down list simply copies the selected value into the textbox - this works.
Next I programmatically select a value from the dropdown list via the button's click event. I was expecting this action to automatically cause the textbox to be populated with whatever value was selected in the drop-down list. However this does not work. The dropdown item changes but the textbox is not populated.
This is probably more of an ASP.NET thing, but I was wondering how this type of event chaining could be achieved using the RadAjaxManager.
Thanks.

Hello Michael,
The RadAjax framework simply converts all the postback into an AJAX requests silently updating only a portion of the page. Therefore it cannot trigger updates of controls, which are not updated through standard postbacks.
