Blazor StateHasChanged() Nov. 30, 2018

The Merge

This week the Blazor github repository merged into master on the AspNetCore repository. What does this mean?

  • Obviously the source code has moved
  • Any issues and other GitHub history will migrate to the AspNetCore repo
  • New issues should be raised on the AspNetCore repo
  • While this does not have any bearing on the experimental status of Blazor, it does feel like a larger investment. One could assume that this merge is a bigger commitment.
  • This is likely preparation for ASP.NET Core 3.0. Blazor’s server-side model will be released as “Razor Components” sometime in the future. How soon has yet to be established.

The Many Ways to Bind Data in Blazor

On the show a detailed example of data binding with Blazor was shown. This project by SQL-MisterMagoo walks through every binding scenario. It includes interactive pages that highlight when data is bound for a visual connection with how parent-child relationships work with binding in Blazor. The project also gives example of how to deal with a known issue where StateHasChanged isn’t called on the parent when bind-{property} is used.

TabSet Deep Dive

An Step-Wise or Wizard form UI is an example from the ASP.NET and Kendo UI frameworks I wrote a few years back. It has been quite a popular example receiving numerous page views and comments. The concept uses a progress bar, tab set, and buttons to create a step-by-step form. The same type of form would be useful in Blazor, but the current examples of a tab set are basic and lack the necessary APIs to interact with at run-time. On the show web started building additional features into the tab set necessary for run-time events and data binding.

The source code can be found on Github:
