Telerik Controls Do Not Work If a Compression Module Is Used in the Project


Product Progress® Telerik® UI for ASP.NET AJAX


When working with Telerik UI for ASP.NET AJAX, the Telerik controls are not working if the project or website uses the Compression module.


The possible reason for this issue is that a double compression of web resources occurs. The web resources requested by the Telerik controls are compressed twice—once by the Script, RadScript, or RadStyleSheet Manager and a second time by the Compression module.


To solve this issue, skip the compression for the requested resource in the Compression module. If the OutputCompression property of the RadScriptManager or the RadStyleSheetManager is set to Disabled, you can configure the Compression module to compress Telerik.Web.UI.WebResource.axd.

Control Requested Resources
ScriptManager WebResource.axd, ScriptResource.axd
RadScriptManager Telerik.Web.UI.WebResource.axd
RadStyleSheetManager Telerik.Web.UI.WebResource.axd
