Hi I'm using a Combobox populated via webservice inside a grid editform template.
When there is no data (InserMode form) the combobox works great.
When There are data I generally set the properties SelectedValue and Text; when I open the EditForm, the page throw a javascript exception and the EditForm won't appear..
This is the javascript exception:
Errore di run-time di Microsoft JScript: Sys.WebForms.PageRequestManagerServerErrorException: Selection out of range
Parameter name: value

Hello max,
This is probably a server-side exception which is reported inside alert box by ASP.NET Ajax. You can try temporarily disabling ajax to debug the server-side error (set the EnableAJAX property of your RadAjaxManager or RadAjaxPanel to false). You could also open a support ticket and send us a runnable version of your application which we can troubleshoot.
