I think this is a bug of Store

            if (!string.IsNullOrEmpty(query))

                this.Store1.DataBind();
            }
        }

if the first query no result
after,all of query will no result both

first query post

submitAjaxEventConfig{"config":{"extraParams":{"start":0,"limit":5,"query":"no_result_key"}}}

first query response

{serviceResponse:{Success:true},script:"WindowSite.close();"}

after query post

submitAjaxEventConfig{"config":{"extraParams":{"start":0,"limit":5,"query":"00"}}}

after query response

{serviceResponse:{Data:{data:[{"Name":"BD-0053","ImageMiniURI":"~/Files/ProductImages/e942270f-e8f0-49f9-bf8f-d2453213ed21_mini

: 497},Success:true},script:"WindowSite.close();"}

data return right,but no bind with combobox or store

[geoffrey.mcgill]

The uppercase "Success:true" the response seems a bit strange. I think it should be "success:true".

I am going to try and reproduce.

why the response not contain "Data:{data:[*],totalCount:n}" when the result is empty

Temporary solution

        protected void Store1_RefreshData(object sender, Coolite.Ext.Web.StoreRefreshDataEventArgs e)
        {
            string query = e.Parameters["query"];

            if (!string.IsNullOrEmpty(query))
            {
                e.TotalCount = BLL.Common.CardDataWay.Count<Entities.SelfMould>(Entities.SelfMould._.Name.Contains(query));
            }
            else
            {         
                e.TotalCount = 0;
            }
            if (e.TotalCount > 0)
            {
                this.Store1.DataSource = BLL.Common.CardDataWay.From<Entities.SelfMould>().Where(Entities.SelfMould._.Name.Contains(query)).ToArray<Entities.SelfMould>(e.Limit, e.Limit * e.Start);
                this.Store1.DataBind();
            }
            else
            {
                this.Store1.SetDataFromJson("[]");
            }
        }

response with noresult

{serviceResponse:{Data:{data:[], totalCount: 0},Success:true}}
