将 DevExterme LoadOptions 发送到 aspnetzero

Question

As mentioned in following document

Developing-Step-By-Step-Angular-DevExtreme-Using-GetPeople-Method-from-Angular

 this.dataSource = new CustomStore({
            key: "id",
            load: (loadOptions) => {
                return this._personService.getPeople("").toPromise();
            }
        });

the getPeople("") has no parameter. when I change it to getPeople(loadOptions) then I get null reference in DataSourceLoadOptions in Back-End. While testing I just ignored the generated proxy and sent it by http and now it works.

Is there something that I should do?

Answer 1

So, I am not an angular expert by any stretch. But I did find this code located here:

DevExtreme ASP.NET Zero Integration

in the Angular section, they had this code:

this.dataSource.store = new CustomStore({
        load(loadOptions: any) {
            var maxResultCount = loadOptions.take || 10;
            var skipCount = loadOptions.skip || 0;
            var sorting = '';

            if (loadOptions.sort) {
                sorting = loadOptions.sort[0].selector;
                if (loadOptions.sort[0].desc) {
                    sorting += ' desc';
                } else {
                    sorting += ' asc';
                }
            }

            return self._auditLogService.getAuditLogs(
                self.startDate,
                self.endDate,
                self.username,
                self.serviceName,
                self.methodName,

..........

Maybe this would help.

Good luck. Let us know how you resolved it!
