While I’m in the process of converting my Angular 1.x directives into Angular2 components, the tri-state checkbox reared its head. This is a pretty common mechanism and is something I needed to have working before moving along to converting other components.

Long, long ago, I blogged about Angular 1.x Request Interceptors and how they can be used to display a loading indicator. I really liked that mechanism. You could intercept any request whether you made it or it was made by the framework. Fast-forward to today, and things are significantly different with Angular2.

In my previous post detailing how to create a DialogService for Angular2, I provided a simple service to display a confirmation dialog. The idea that I had in mind when writing that was to incorporate it into Angular2’s Routing lifecycle with a Menu system. Ultimately, it would be used to determine dirty states and display a dialog to the user asking if they want to keep or discard their changes.

An important aspect of any web application is displaying messages to users based on events. I like to use modals for this. Angular2’s Bootstrap components provide some basic functionality to facilitate the creation of Modal Dialogs.

In one of my previous posts, I detailed using Table Value parameters. That method works great for my uses. However, I ran into one gotcha worth pointing out.

It’s been a while, but I had some time today to work a bit more on my Angular2 multiselect implementation. The next aspect that I wanted to implement is validation.

One deficiency with Entity Framework is the ability to load data from a stored procedure or a direct query when the column names don’t match your model property names exactly. In one of my previous posts, I detailed how the EF API can be used to retrieve column mappings. These column mappings can be used in conjunction with a SqlDataReader to map a query result, properly, to your EF model.

Recently I posted about a method I use in JavaScript (Angular specifically) to transform posted Date objects to transmit the local DateTime. It’s a simple method that uses JavaScript’s “toLocaleString” method while intercepting POST requests. Everything worked fine except when IE11 was introduced into the equation.

In a previous post, I demoed how to use Table Valued Parameters (TVP’s) with EF. This works great, but, if you’ll notice, it only suppports one-column TVP’s with a simple scalar list of values. I expanded this a bit.

There are a few limitations of Entity Framework 6.x that require various work-arounds. One of those limitations is not being able to take direct advantage of entity mappings that are defined. However, it is possible to utilize Entity Framework’s API’s to retrieve and consume this information.
