问题 I have records with a boolean value, and depending on the boolean value, I would like the GridPanel's rows to be rendered bold. I'm sure there is a nice GridView style way to do this but I can't seem to find it. Thanks. 回答1: Your answer is correct, but I want to point out that there's no need to provide an instantiated GridView instance in order to override getRowClass. Use the GridPanel's viewConfig instead: viewConfig: { getRowClass: function(rec, idx, rowPrms, ds) { return rec.data.isRead

问题 I have an Extjs Grid with a Paging toolbar. I need to pass the server custom parameters for each request I make when paging the data.

问题 For a scenario using 0 ASP.NET controls at all but rather an 100% extJS interface, what would be the advantages of using ASP.NET MVC or ASP.NET WebForms? And the disadvantages? Is there a OBVIOUS way to do it properly? I would love to have feedback's on your experiences. Thank you! 回答1: WebForms + any purely client-side framework will give you nothing but endless headaches, if you can get it working at all.
