I have a dynamic module with two content types 1) Traded Funds and 2) Historic Data the second of which has the first as its parent. Each historic data entry has a date and also stores two additional fields storing the traded values for that day.
I'm creating a custom widget using MVC and trying to query the historic data filtering by dates so that the user can view only a selected number of days' worth of financial data.
Here's a sample of code I'm using:
var dynamicModuleManager =
Type typeETF = TypeResolutionService.ResolveType(
Type typeHistoricData = TypeResolutionService.ResolveType(
//get the fund that we're dealing with
var fundItem = dynamicModuleManager.GetDataItems(typeETF).Where(x => x.UrlName == urlName && x.Status == Telerik.Sitefinity.GenericContent.Model.ContentLifecycleStatus.Live && x.Visible ==
var newFromDate = from.Subtract(TimeSpan.FromDays(1));
var newToDate = to.AddDays(1);
//now get the child items
var childItems = fundItem.GetChildItems(typeHistoricData)
.Where(x => x.Status == ContentLifecycleStatus.Live
&& x.Visible ==
) > newFromDate
) < newToDate).ToList();
var childItems2 = dynamicModuleManager.GetDataItems(typeHistoricData).Where(x => x.SystemParentId == fundItem.OriginalContentId
&& x.Status == ContentLifecycleStatus.Live
In both attempts childItems and childItems2 the count returned is zero.
There is data available for the days I'm selecting so I'm not sure why this is happening. I seem to be able to filter/sort on other fields except Date.
