Using Shortcut Key in Web Applications using jQuery


Introduction

Download

Comparing Web Applications to Windows Applications has been always a debate topic. Now, I'm trying to add one more topic in this debate.
We can add Keyboard Shortcuts to our Web Application (Websites) so that when user types first letter, we will have the page behave as if the corresponding button were pressed/clicked.

We need to know which key was pressed when our keyup handler gets triggered. We can inspect the event object for this. The .keyCode property of the event contains an identifier for the key that was pressed and for alphabetic keys; this identifier is the ASCII value of the uppercase letter. So we can create a map or object literal of letters and their corresponding buttons to press/click. When the user presses a key, we will see if its identifier is in the map and if so, trigger the action.

Now, I'm going to add this feature to my one of the article "Example on jQuery Event Bubbling Situation". Download the attachment from there. This article has mouse click event already so I'm going to implement it to create keyboard shortcut functionality too.

Let's begin and add following jQuery code to existing project that you have download.


Now, look at the animated image that works for me.


I hope you like it. Thanks.

Migrating database from ASP.NET Identity to ASP.NET Core Identity

Image
As you know ASP.NET Core Identity (table structure) is different from what we had earlier in ASP.NET Identity. Actually the identity system which we have today with .NET Core is very mature and continuously evolved be it ASP.NET Membership, ASP.NET Identity 1, ASP.NET Identity 2 and now ASP.NET Core Identity. Recently I had to migrate few application to ASP.NET Core and similar its identity database. Because the table schema is changed, i had to re-think and create migration script which I would like to share with you today. It is very simple and easy, just three step and I had everything ready: STEP 1 : Change name of existing tables STEP 2 : Create ASP.NET Core Identity tables STEP 3 : Migrate data from old tables (ASP.NET Identity) to new tables (ASP.NET Core Identity) Script:  https://gist.github.com/itorian/c699e8534b392a6c726ec66c48100072 You should also watch my video, where I demoed migration.

Lambda two tables and three tables inner join code samples

In this blog post you will learn inner join using lambda queries. There will be two samples, in first sample you will see how you can join two tables and in second sample you will see how you can extend even further to join three tables and so on. I will sample in-memory data, but the same implementation will work with IQueryable (lazy query) too. Here's the code snippet:- namespace ConsoleApp1 {     class Program     {         static void Main()         {             var table1 = new List<Table1>();             table1.Add( new Table1 { Id = 1, Name = "Name 1" , Address = "Address 1" });             table1.Add( new Table1 { Id = 2, Name = "Name 2" , Address = "Address 2" });             table1.Add( new Table1 { Id = 3, Name = "Name 3" , Address = "Address 3" });             table1.Add( new Table1 { Id = 4, Name = "Name 4" , Address = "Address 4" });
