Broken File Browser Dialogs

Unregistered handler for RadAsyncUpload breaks the File Browser dialogs of RadEditor in Q3 2012


If the Telerik.Web.UI.WebResource.axd handler is not registered AsyncUpload will not function correctly and the File Browser (ImageManager, DocumentManager, MediaManager, etc) dialogs will look in a similar way:



To provide better File Upload experience and usability, starting from Q3 2012, RadAsyncUpload is enabled out-of-the box in RadEditor's File Browser dialogs. Therefore the handler for the AsyncUpload should be registered in the web.config explicitly:

    <add path="Telerik.Web.UI.DialogHandler.aspx" type="Telerik.Web.UI.DialogHandler" verb="*" validate="false" />
    <add path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" validate="false" />
    <add name="Telerik_Web_UI_DialogHandler_aspx" verb="*" preCondition="integratedMode" path="Telerik.Web.UI.DialogHandler.aspx" type="Telerik.Web.UI.DialogHandler" />
    <add name="Telerik_Web_UI_WebResource_axd" verb="*" preCondition="integratedMode" path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" />

Both Telerik.Web.UI.DialogHandler.aspx and Telerik.Web.UI.WebResource.axd handlers can be registered in the web.config file via the RadEditor's smart tag.
