Managing Timespans in a Blazor Server App

Working with time can be tricky, especially when it comes to displaying and manipulating time intervals in software applications. In Blazor server apps, defining and managing TimeSpan values can add complexity when you want to convert these values into a user-friendly format, like a 12 hour format.

In this guide, we will walk through a simple solution for binding TimeSpan properties and converting them to a 12 hour format.

Understanding the Problem

When designing an application that requires managing time slots, we often have to deal with properties like:

FromTime: Starting time of the slot (as a TimeSpan).

ToTime: Ending time of the slot (as a TimeSpan).

DisplayText: A string representation of the time slot.

The challenge arrives when trying to bind these values in a Razor component and convert them to a more readable format for display.

Key Requirements:

Add timeslot settings, edit them, and store them in a database.

Convert TimeSpans to a 12-hour format for better readability.

Implementation Steps

Step 1: Creating the Model class

First, we define our model class SomeModel that includes the necessary properties.

Step 2: Setting Up the Razor Component

Next, we will create a Razor component to handle user inputs. We will bind FromTime and ToTime properties to <input type="time"> controls for better time selection.

Here’s how you can structure your component:

Step 3: Adding Logic in the Code-Behind

In the corresponding code-behind file, we define how to handle the binding and time conversion:

Step 4: Database Read and Update

Now, ensure you implement the logic to read from and save your models to the database. When reading a TimeSpan, we can directly cast it from the database, and for writing back to the database, convert back using the corresponding methods.

For example:

Conclusion

By following these steps, you can effectively manage and display TimeSpan values in your Blazor server applications. Not only can you bind these properties to user inputs, but you can also provide a user-friendly 12 hour format, enhancing the overall user experience.

Always remember to test your implementation thoroughly to ensure that the conversion logic works as expected before deploying updates to your application. Happy coding!
