Filtering Data in ASP.NET MVC Table Based on Tab Selection

If you're working with ASP.NET MVC and want to provide users with an interactive way to view different data sets, filtering table data based on tab selection is an effective approach. This guide will walk you through the process of achieving this functionality step by step. We'll cover how to set up your view, how to handle requests in the controller, and how to bind the filtered data effectively.

Understanding the Problem

Imagine you have a data table displaying various regions and their countries, and you want users to be able to filter the view simply by clicking on tab headers — for example, "North" and "South". Your initial setup includes tabs for navigation but lacks the ability to actually filter the displayed data based on the selected tab.

Current View Setup

Your current view code looks like this:

Currently, the logic for filtering has not been solidified. You need to implement a method in your controller to facilitate this.

Implementing the Solution in the Controller

To enable the filtering logic, you'll need to modify your controller to receive the tab selection as a parameter and filter the data accordingly. Here's how to do that:

Controller Method

Assuming you’re using Entity Framework, your controller method should look something like this:

Explanation of the Code

Action Method: The Index action method takes a string parameter REGION_NAME_BASED_ON_TAB, which represents the selected tab.

Data Querying: We create a variable model to select from your data table. If a region name is provided, we filter the data based on whether it contains the specified region name (case insensitive).

Return View: Finally, we return the filtered list to the view for rendering.

Updating the Tab Links

Now, you need to make sure each tab link passes the appropriate region name to your controller. Update your tab structure to look like this:

Key Takeaways

Each tab is linked to the Index action of your controller with a specific region name passed as a query parameter.

This setup allows the filtering logic to trigger correctly based on the tab selected.

Conclusion

By following the steps above, you can create a functional data filter in your ASP.NET MVC application, letting users explore data based on specific regions dynamically. The combination of controller action and properly linked tabs will ensure that the right data is displayed in your table based on user interaction.
