Reusing Radzen DataGrid within the Same Layout Under an if Statement

When working with Blazor applications that utilize the Radzen DataGrid, developers often encounter scenarios where multiple instances of the same grid must be created to handle different datasets. This approach can quickly become tedious and unmanageable, leading to code duplication and maintenance challenges. In this guide, we will explore how to avoid this issue by implementing a single reusable DataGrid under conditional statements.

The Problem

Imagine you're building a Blazor application and need to display a Radzen table that can show different sets of data based on various conditions. Ordinarily, you might create multiple instances of the DataGrid with minor variations in setup. The resulting code might look like this:

Why This Isn't Ideal

Code Duplication: You have to replicate the DataGrid structure and functionality three times, making updates cumbersome.

Increased Complexity: Maintaining three separate grids leads to a more complex codebase, increasing the likelihood of errors.

The Solution

Unfortunately, it is not possible to use a single Radzen DataGrid with different type parameters, or TItem, directly. However, you can overcome this limitation by unifying your data under a single class. Here’s how:

Step 1: Create a Common Class

To facilitate the reuse of the Radzen DataGrid, create a common class that incorporates the properties of all potential TItem classes. For example:

Step 2: Transform Your Data

When fetching your dataset, ensure that each dataset is transformed into the CommonModel. For instance:

Step 3: Use Conditional Logic

Finally, you can utilize an if statement to conditionally bind the DataGrid’s data property based on your application’s logic.

Key Takeaways

Avoid Duplication: By creating a common class and transforming your datasets, you reduce code duplication significantly.

Simplify Maintenance: A single reusable DataGrid means fewer lines of code to maintain and a clearer structure.

Adaptable Design: This approach allows for easier adjustments and scalability to accommodate future data needs.

Conclusion

Utilizing a single Radzen DataGrid to handle different data sets not only streamlines your code but also enhances the overall maintainability of your Blazor applications. By following the outlined approach of using a common model and conditional logic, you can achieve a cleaner, more efficient solution.

Implement this method in your next project, and save time and effort while building robust applications. Happy coding!
