I already posted a reply in the other thread you started with the same question. Let us continue the discussion in it as you provided more information there.
For your convenience, I give you the information here as well:
created a simple test pages, based on the provided information and code
but was not able to reproduce the problem you describe. I have attached
my test page for your reference.
Could you please try the following - set EnableAJAX="false" for the
RadAjaxPanel to see if the grid will show the new records. I suggest
that you try this as I noticed that the toolbar
button that you use to rebind the grid in not in the RadAjaxPanel - in
order to rebind the RadGrid during an AJAX request, you need to update
In case the test page or suggestion does not help you fix the problem,
please prepare and send me a simple running project, demonstrating the
problem as well as detailed information on the steps I need to follow
in order to reproduce it.
