How to Filter by Date Range in MudBlazor Table using Blazor

If you're venturing into the world of Blazor and MudBlazor, you may find yourself facing specific challenges while creating dynamic applications. One typical scenario is the need to filter data in a table by date range. If you have an invoicing application displaying a table and require users to filter invoices by their date, you're in the right place. Let's dive into how you can implement this feature.

Understanding the Problem

You have a MudBlazor Table displaying invoices. The goal is to enable users to filter this table using a date range. However, with your current implementation, changing the date range does not trigger the expected API calls or the data retrieval process. Specifically, the GetServerData function is not being fired, and it appears that the OnSearch function is not called as needed.

Solution Overview

The key to resolving this issue lies in how the change event is handled. You may have used a typical @onchange event handler, which sometimes doesn't work as intended with MudBlazor components. Instead, you should utilize MudBlazor's specific bindings to efficiently call your filtering function whenever the date range changes.

Step-by-Step Implementation

Here’s how you can set up the date range filtering effectively.

Use the MudDateRangePicker Correctly:
Instead of relying on the @onchange attribute, use the DateRange and DateRangeChanged properties. Splitting the @bind-DateRange allows you to bind the date range in two parts—one for the value and one for the change event.

Here’s the code snippet that clarifies this:

DateRange: This property holds the current range selected by the user.

DateRangeChanged: This event fires whenever the date range gets updated. You can assign a lambda function to update your dateRange and call the OnSearch function, which will handle the necessary data fetch.

Refreshing the Table Data:
Inside the OnSearch method, make sure you're triggering a reload of the server data after the date range is set. This ensures that whenever a user changes the date, the new data gets fetched and displayed accordingly.

Here's a simple implementation for OnSearch:

Fetching Data from the Server:
Ensure your GetServerData function appropriately handles the new date range. Here it is:

Conclusion

Implementing a date range filter in a MudBlazor table enhances your application's user experience. By using MudBlazor's specific event handling for inputs, you can ensure that updates reflect live in your data. This method helps streamline user interactions and maintains the integrity of application performance.
