I am a professional software engineer and architect with over eighteen years commercial development experience with a strong focus on the design and development of web and mobile applications.

I have experience of architecting scalable, distributed, high volume web applications that are accessible from multiple devices due to their responsive web design, including architecting enterprise service-oriented solutions. I have also developed enterprise mobile applications using Xamarin and Telerik Platform.

I have extensive experience using .NET, ASP.NET, Windows and Web Services, WCF, SQL Server, LINQ and other Microsoft technologies. I am also familiar with HTML, Bootstrap, Javascript (inc. JQuery and Node.js), CSS, XML, JSON, Apache Cordova, KendoUI and many other web and mobile related technologies.

I am enthusiastic about Continuous Integration, Continuous Delivery and Application Life-cycle Management having configured such environments using CruiseControl.NET, TeamCity and Team Foundation Services. I enjoy working in Agile and Test Driven Development (TDD) environments.

Outside of work I have two beautiful daughters. I enjoy cycling, running and taking the dog for long walks. I love listening to music and am a fan of Rush and the Red Hot Chilli Peppers to name a few.

GeneralExecuting an AJAX request from an ASP.NET Core querystring parameter Pin
Dominic Burford20-Aug-18 6:05
professionalDominic Burford20-Aug-18 6:05 
I recently had to figure out how to execute an AJAX request upon loading an ASP.NET Core Razor page which contained a querystring parameter. On one of our Razor pages, we have a Kendo UI Treeview. Clicking on this treeview populates the page with data for the selected item. The click event on the treeview executes a Javascript event, which in turn makes an AJAX request to a service to fetch the data for the selected item. This Javascript event then populates the Razor page with the returned data.

When launching the Razor page interactively from the menu the URL looks like this.

https://localhost/DocumentManager/DocumentManager

When launching the Razor page for a specific item programmatically the URL looks like this.

https://localhost/DocumentManager/DocumentManager?documentid=1234

So basically, the page is populated with data from an AJAX request which is fired from a Javascript event. The problem I had was that we needed to open this page and load up the data for a specific item. Whereas currently the item is selected by the user interactively clicking on an item from the Kendo UI Treeview, I now had to figure out how to load the page data for an item progrmmatically.

So here's how I did it.

I firstly needed to figure out if the Razor page was being launched interactively (with no querystring parameters) or programmatically (with querystring parameters). I did this using URLSearchParams URLSearchParams - Web APIs | MDN[^]. This is an interface that allows a Javascript client to manipulate and work with querystring parameters. This offers a far simpler and elegant mechanism for working with querystring parameters than horrible string manipulation and / or regex queries.

I was passing a document ID to the Razor page in the form of:

https://localhost/DocumentManager/DocumentManager?documentid=1234
<div>
  rest of the Razor page goes here
</div>
<script>
    $(document).ready(function () {
        var queryparams = window.location.search;
        //using URLSearchParams to extract the querystring parameter
        if (queryparams && typeof (queryparams) === "string" && queryparams.length > 0) {
            var urlParams = new URLSearchParams(window.location.search);
            var documentid = urlParams.get('documentid');
            //call the JS function that will make the AJAX request and fetch the data
            loadDocumentManagerForDocument(documentid ); //see below for definition!
        }
    });
</script>
In our JS file site.js the function that makes the AJAX request is defined as follows.
function loadDocumentManagerForDocument(documentid) {
    if (documentid) {

        //AJAX call to Razor page handler to fetch the document details

        $.ajax({
            type: "GET",
            url: `/DocumentManager/DocumentManager?handler=document&documentid=${documentid}`,
            contentType: "application/json",
            dataType: "json",
            success: function (response) {
                //populate the form elements with the returned data
            },
            failure: function (response) {
                //handle the error
            }
        });
    }
}
Finally, here is the Razor page handler that fetches the data. Remember, this is the same Razor page handler that is used for both loading the data interactively (as the user clicks items from the Kendo UI Treeview) and programmatically.
public async Task<JsonResult> OnGetDocument(int documentid)
{
    JsonResult result = null;
    var response = await new DocumentManagerPageModelService().GetDocumentById(documentid);
    result = new JsonResult(document);
    return result;
}
Here is yet another example demonstrating the incredible flexibility and power of ASP.NET Core. This solved what I was thinking may be a really tough problem, but in the end it wasn't really that difficult. With a bit of thinking the problem through, the solution is quite straight forward. I hope this solution helps someone else.
"There are two ways of constructing a software design: One way is to make it so simple that there are obviously no deficiencies, and the other way is to make it so complicated that there are no obvious deficiencies. The first method is far more difficult." - C.A.R. Hoare
