问题 Hy, I have a problem with extjs and grails. When I a try call the next page of the grid, I don't have the objects. The grid still with the old objects. How can I do to paginate my grid? 回答1: add below to your store cfg: paramNames: {start:'offset',limit:'max',sort:'sort',dir:'order'}, baseParams: {offset:0,max:this.pageSize}, then the controller: def result = Floor.createCriteria().list( max:params.int('max')?:100, offset:params.int('offset')?:0 ) render ([count:result.totalCount,data:result]

问题 I have a ComboBox with a remote json store. It lets the user type in 3+ characters, then queries, displays list and lets user select one option. When the user selects an option, it uses the Ext.data.Record associated to the selected option to populate other fields elsewhere in the form. This works correctly. Now I want to be able to pre-populate the said fields, by using the functions that I've already written as part of the combo box. What I have come up with, is to add an "artificial record

问题 I'm trying to convert DataTable to JSON using Newtonsoft.JSON but found that the output is not what ExtJS grid and chart would expect. My code is string output = JsonConvert.SerializeObject(dt, Formatting.Indented, new JsonSerializerSettings { ReferenceLoopHandling = ReferenceLoopHandling.Ignore }); and this returns Json string as "[{\"DAYDATE\":\"2012-05-22T00:15:00\",\"SERIES1\":3.65}]" If I remove '\' and start and end double quotes it works fine with ExtJS. I also tried changing date

问题 In Ext 4.1, I am dropping items to a grid, but the records come in with an id and the phantom flag is set to false, causing the store to remain empty and not add those records to it. even though they appear fine on the grid. I read several solutions online, and many suggested setting the phantom flag to false and/or setting the id to null, but I am not able to implement this? Where do I set it?
