Methods

FetchPageAsync<T, TKey>(TableModel<T, TKey>, IQueryable<T>, TableState)

Uses the given columns and tableState to extend the given queryable for appropriate filtering and sorting, and then executes the query twice; once to count rows so that PageCount can be calculated, and once with pagination applied. Places the results in the given TableModel<T, TKey>.

public Task FetchPageAsync<T, TKey>(TableModel<T, TKey> tableModel, IQueryable<T> query, TableState tableState) where T : class

Parameters

tableModel TableModel<T, TKey>

The table model to populate with data and metadata.

query IQueryable<T>

The queryable to execute.

tableState TableState

1. Applies text-based filtering using column filter delegates
2. Applies range-based filtering for date/numeric ranges
3. Applies sorting based on the current sort column and direction
4. Executes a count query to determine total records and page count
5. Applies pagination and executes the data query
6. Populates the table model with rows and metadata
