A Generic and Advanced PDF Data List Reporting Tool

|
By Shenwei Liu
| The Code Project
Many business applications need to export the data lists to PDF files. Since the PDF components are physically rendered on document pages, the best practice of obtaining a data list in PDF format is to directly generate a PDF data list report with the help of a PDF rendering tool. Uzi Granot shared his excellent and lightweight base PDF rendering class library, PdfFileWriter, with the developer’s communities.

|
By Shenwei Liu
| The Code Project
Returning multiple result sets from a stored procedure has been supported since Entity Framework (EF) 5.0. However, the approach of mapping configurations for the feature using the EF designer has not been available even from EF 6.0. MSDN only posted limited instructions on the topic of returning multiple result sets with simple entity types. Any business data application more or less needs to retrieve multiple result sets of data from stored procedures to avoid multiple calls.

Server-side Data Filtering, Sorting, and Paging with AngularJS, trNgGrid, ngTable, and Web API

|
By Shenwei Liu
| The Code Project
Server-side data filtering, sorting, and paging are not a new topic, even in the AngularJS world. Many AngularJS grid tools are available nowadays but very few decent samples can be found using a grid tool for the server-side pagnated data set like using the jqGrid in JQuery. This article presents a sample of a pure HTML 5 and AngularJS SPA website implemented with a search module for data filtering and two AngularJS grids, trNgGrid and ngTable, for requesting and displaying the data.
