Paging in ASP.NET Core MVC and EntityFramework Core

8 Comments
By Fons Sonnemans, 29-3-2017

Paging, sorting and filtering are common features in websites. Microsoft has written a tutorial how to implement these features in ASP.NET Core MVC with Entity Framework Core. The described solution works but I found it a bit too primitive. It triggered me to create a more powerful solution. Before you can start using my solution you should first read this tutorial, it explains how you can add Entity Framework Core to an ASP.NET Core MVC application.

By Fons Sonnemans, 24-3-2006

Sorry Dutch only.

Vanwege mijn brede expertise en de aantrekkende markt krijg ik de laatste tijd veel leuke opdrachten in Nederland en België aangeboden waarop ik regelmatig nee op moet verkopen. Daarbij wordt mij meestal ook gevraagd of ik in mijn netwerk nog andere .NET freelancers ken. Daarom heb ik een netwerk opgezet zodat ik potentiële opdrachtgevers kan doorverwijzen naar een collega.

Via deze blog nodig ik .NET freelancers uit zich gratis en vrijblijvend bij mij aan te melden. Mijn netwerk is alleen voor Microsoft specialisten, hierbij gaat het dus om:

  • Software Architecten
  • Team en Projectleiders
  • Coaches
  • Trainers
  • Ontwerpers
  • Programmeurs (C#, VB.NET, ASP.NET, SQL, XML)
  • DBA’s
  • Web-designers
  • (unit)testers

Aanmelden kan heel eenvoudig via een e-mailtje naar dotnetwerk@reflectionit.nl.

I just saw the great Sparkle video on Channel9. On of the most funny part was the question 'What is an Architect?'. The anwer from John Gossman was 'It is a fancy title for a programmer' or in other words 'You are old'. I hope you enjoy the movie, I did. I can't wait to play with it.

Microsoft has put my 'Dual List' .NET Magazine article online!

Microsoft has put my Visueel programmeren met .NET: Dual List Control article online. It is published in the .NET Magazine #8 and it is free for Dutch developers.
They didn't publish the sourcecode (yet) but you can download it from my own site. The aricle is in Dutch. You can find an (old) English version of this article here. An even more advanced implementation that also supports Drag & Drop can be found here.

WaitCursor

0 Comments
By Fons Sonnemans, 10-2-2005

For a long time I thought that I only had to set the Cursor.Current to a WaitCursor before a long running operation, the .NET runtime would reset it back to the Default cursor. Turns out that this is only true when the mouse is moved. Bummer.

// Cursor.Current are automatically reset to Default when the
// mouse is moved and the application is idle!
Cursor.Current = Cursors.WaitCursor;

The solution for this problem is very easy. I created a helper class called WaitCursor which set the Cursor.Current and restores it to the original value when it it disposed.

public sealed class WaitCursor : IDisposable {   &nbsp   &nbsp   &nbsp   &nbsp
   &nbspprivate Cursor _prev;

   &nbsppublic WaitCursor(){
   &nbsp   &nbsp_prev= Cursor.Current;
   &nbsp   &nbspCursor.Current = Cursors.WaitCursor;
   &nbsp}

   &nbsppublicvoid Dispose(){
   &nbsp   &nbspCursor.Current =_prev;
   &nbsp}
}

I create the instance of the WairCursor class inside a using statement. This will automatically call the Dispose() method when it goes out of scope.

Dispose Modal WinForm Dialogs

0 Comments
By Fons Sonnemans, 12-12-2004

There is a difference in disposing Modal and Non-Modal forms. In a training I gave last week I noticed that even experienced developers didn't know that Modal Dialogs don't dispose automatically, Non-Modal do.

private void buttonShowNonModalForm ( object sender , System.EventArgs e){
   &nbspnew TestForm().Show();
}

privatevoidbuttonShowModalDialog(objectsender, System.EventArgs e){
   &nbspnew Form2().ShowDialog();
}

The solution to this problem is very simple by creating the Form instance within a using block. This will dispose the Form when it is closed.

private void buttonShowModalDialog ( object sender , System.EventArgs e){
   &nbspusing(TestForm f =new TestForm()){
   &nbsp   &nbspf.ShowDialog();
   &nbsp}
}

An alternative solution uses a try/finnaly. Personally I prefer the previous, it is easier to read and write.
