I am stuck on problem where my facade method is never called so my returned items are always zero. I dont exactly know why this happens since it should at least load items on initial page load. Also I got almost identical ViewModel where it works fine.
Here is my viewmodel where I want to load FavouriteCommodities into GridViewDataSet
//initialized via constructor
private readonly FavouriteCommodityFacade _favouriteCommodityFacade;
public GridViewDataSet<FavouriteCommodityDTO> GridViewDataSetItems { get; set; }
public int PageSize { get; set; } = 10;
private ISortingOptions DefaultSortOptions => new SortingOptions();
public override Task Init()
{
GridViewDataSetItems = new GridViewDataSet<FavouriteCommodityDTO>()
{
PagingOptions = { PageSize = PageSize },
SortingOptions = DefaultSortOptions
};
return base.Init();
}
public override Task PreRender()
{
if (!Context.IsPostBack || GridViewDataSetItems.IsRefreshRequired)
{
LoadData();
}
return base.PreRender();
}
public void LoadData()
{
FavouriteCommodityGroups = _userAccountFavouriteProductsFacade.GetAllFavouriteProductsToUser();
//this never fires my facade method below
GridViewDataSetItems.OnLoadingData = option => _favouriteCommodityFacade.GetAssignedFavouriteProductsToGroup(option);
}
Here is my method in my facade which is never fired.
public GridViewDataSetLoadedData<FavouriteCommodityDTO>
GetAssignedFavouriteProductsToGroup (IGridViewDataSetLoadOptions gridViewDataSetLoadOption)
{
using (unitOfWorkProvider.Create())
{
var query = _favouriteCommodityByChosenGroupQuery();
FavouriteProductByGroupFilter.FavouriteGroupId = 16;
query.Filter = FavouriteProductByGroupFilter;
var x = GetGridViewDataSetLoadedData(gridViewDataSetLoadOption, query);
return x.Result;
}
}
I am also wondering if there is possibility to load those items on user click event. When I looked into namespace DotVVM.Framework.Controls I didnt find anything useful for that.
