We use Telerik AJAX ASP.NET extensively. On one page the page response time is very critical. On this page we are using RadGrid and RadComboBox. We have included RadScriptManager too.
One issue we are facing is that when user accesses this page for first time then Telerik.Web.UI.WebResource.js file is downloaded. This file is about 0.7 MB is size! This is creating major performance issues due to which we are being forced to re-write the page without Telerik.
Is there a way to reduce this size? On this particular page we are just using the RadGrid and RadComboBox- is there a way that we include the js for just these two controls? Or is there some other way?
Note: Using Telerik CDN is not going to help as using this yet on first visit the js file size would remain the same. Using RadCompression is not going to help as main problem is the 0.7 MB size of Telerik.Web.UI.WebResource.js.
I googled a bit but did not find a solution. PLEASE HELP, else its bye bye Telrik for us!
