As per the documentation of webgrid, with client binding, the size of javascript footprint could be significantly reduced. And as i seen from another topic in this community, the code below could

<add key="ISNet.WebUI.ISRes_Compressed" value="true" />

reduce the data by enabling compression. But by checking YSLOW, i could see that the corresponding javascript and gzip format differ in size by a large and from firebug Net result i could see that total size is not altered at all. So i cleared cache, restarted the project and refreshed smartwebresources. No change at all. What i am doing wrong? Am using Webgrid 7.0 with SP1 installed. And what about the following lines 

<add key="ISNet.WebUI.v3_0_5000.OptimizeCss" value="true" />
<add key="ISNet.WebUI.v3_0_5000.OptimizeCssName" value="true" />
<add key="ISNet.WebUI.v3_0_5000.GroupCssStyles" value="false" />
