I am using 2 RadButtons to search for a (Host or Victim) student then load 2 Radgrids via ajax.
I am pre populating the search criteria txtFirstName with "Cor" and txtLastName with "A".
This returns 5 rows from my DB.
When the Radgrids bind the ajax fires correctly and I can compare the 2 Students below.
In the Other radgrids that hold additional information.
If I change my search criteria to something else that will return more rows to the RadGrid.
The ajax is only firing for the first 5 rows.
If I swap out my 2 search RadButtons with regular ASP:Buttons and fire a post back to bind the 2 SearchRadGrids then all the rows are able to fire the ajax correctly.
any help is appreciated? Thanks

Hello Brian,
I reviewed the provided code and noticed some basic issues with the ajax settings you are adding in your application:
1. Please note that it is not supported to have RadAjaxPanel added in the RadAjaxManager settings or use the both controls for updating the same part of the page. Therefore I would suggest you to replace the RadAjaxPanel with regular asp Panel.
2. Note that single PageView of control form PageView could not be added as AJAX initiator or updated control in the AJAX settings. The only possible approach is to add the whole MultiPage in the RadAjaxManager settings or wrap the whole control into RadAjaxPanel. When we set the MultiPage as an updated control, you should also include the TabStrip associated with it in the Ajax settings.
Review the following help topic for more information on this matter:
