Effective data filtering and handling in AG Grid.
When working with large datasets in web applications, a robust grid system can make data management significantly easier. One such powerful solution is AG Grid, a flexible and feature-rich grid component for JavaScript applications. In this article, I'll explore how to implement and customize AG Grid in Angular applications, demonstrating its capabilities and potential.
To begin with, setting up AG Grid in an Angular project is a straightforward process. Using the Angular CLI, you can quickly scaffold a new application. Once the application is generated, adding AG Grid involves installing the necessary packages: AG Grid Community for basic features and AG Grid Angular for Angular-specific functionality. The AG Grid module is then imported into the application's module, allowing you to start integrating grid features.
Data and column definitions are crucial for a functional grid. Typically, data is fetched from a backend server, but for this demonstration, a local JSON file is used. Angular's HTTP client is employed to load this data into the application. AG Grid supports dynamic data updates, which is essential for applications requiring real-time data handling.
AG Grid's flexibility is evident in its ability to sort and filter data. By setting column definitions as sortable or filterable, users can easily manipulate data views. Default column definitions reduce repetitive configurations, ensuring consistency across grid columns. AG Grid also supports custom filtering, allowing developers to implement complex filtering logic, such as date comparisons or conditional filters.
Another notable feature of AG Grid is the ability to customize cell rendering using Angular components. This capability allows developers to replace default cell renderers with custom components, providing enhanced data visualization. By implementing the AG Grid cell renderer interface, custom components can be tailored to display data in unique and interactive ways.
AG Grid's integration with Angular extends to event handling, offering numerous hooks for responding to user interactions. For instance, row selection can trigger specific application logic, enhancing interactivity. Developers can leverage AG Grid's API to perform actions like clearing selections, demonstrating the grid's programmability.
AG Grid's Enterprise edition introduces advanced features, including server-side row data handling, enhanced filtering, and data export capabilities. The set filter feature in the Enterprise edition offers improved data categorization and filtering options, especially useful for applications with complex data structures.
Row grouping and aggregation are powerful tools for summarizing and analyzing data. By enabling row grouping, users can organize data hierarchically, with options to aggregate values using functions like sum or average. This functionality is particularly beneficial for applications dealing with extensive datasets, allowing for meaningful insights through data visualization.
AG Grid also supports charting, providing users with interactive data visualization directly within the grid. This feature can reveal trends and patterns in data, offering a visual representation of underlying data structures. The integration of charting capabilities within AG Grid enhances its utility as a comprehensive data management tool.
In summary, AG Grid is a versatile and powerful grid component that significantly enhances data management capabilities in Angular applications. Its extensive customization options, event handling, and support for both community and enterprise features make it a valuable tool for developers looking to build sophisticated data-driven applications. By following the step-by-step guide and leveraging the practical examples outlined in this article, developers can effectively implement and utilize AG Grid to meet their application's unique requirements.

AG Grid also allows the configuration of grid properties to match specific requirements, like enabling or disabling animations, sorting, and filtering capabilities.
The Workshop introduces AG Grid and covers topics such as setting up row data and column definitions, enabling sorting, configuring grid features and user interaction, accessing the grid API, and adding styling. It also explores custom cell renderers, filters, and enterprise features like charting, grid options, and sidebar functionalities. The Workshop concludes with discussions on advanced grid features, aggregation, customizing the context menu, and accessing and updating data in the grid.
We'll start off at the basic level and then build it up into more complicated features. I'll show you how to work with the grid and provide a link to the repo with instructions. I'm Stephen Cooper, a developer at Easy Grid, and I'll guide you through using AG Grid in your applications. Let's get started with the Angular CLI to create a new application. We'll add AG Grid using the AG Grid Community and AG Grid Angular packages. Once we import the AG Grid module, we can start our app and modify the app component to include the necessary code for the grid.
2. Setting up Row Data and Column Definitions
We've set up the row data and column definitions for our grid. We've also added the necessary CSS files, including the core grid CSS and the theme file for AgThemeAlpine. By tying the theme in with AG ALPINE and setting the style to 100%, we have our first grid displayed with the provided row data and column definitions. This is the basic setup to get started with AG Grid. There are different themes available, including a dark mode option.
3. Adding Grid Properties and Enabling Sorting
We'll move on to step two, which involves adding grid properties. We'll mimic data coming from a backend server by using a local.json file. We'll update our application to use the Angular HTTP client and load the data in ngOnInit. We can subscribe to the data, but it's better to make it an observable and use the async pipe. We can also mimic network delays and handle error cases. Next, we'll enable sorting for the data by setting the 'sortable' property to true on the desired columns. We can use the 'default column def' property to avoid copying and pasting the code for each column.
4. Configuring Grid Features and User Interaction
We can set a default column definition to make all columns share the same features. The grid can be configured with options like filters and animations. Users can interact with the grid by selecting rows and responding to grid events. The display of columns can be improved by setting explicit widths or using grid events to auto-size columns. Developers have control over how the grid behaves, including enabling users to change column widths.
5. Accessing Grid API and Adding Styling
We'll demonstrate how to access the grid API and interact with the grid using a view child. The grid API provides a list of grid options and methods that can be called. Next, we'll add styling to the grid, including gold, silver, and bronze colors. By changing the order of the column definitions, we can control the display order of the columns. We can add cell classes to apply CSS styles, either globally or externally to the component. Additionally, we can make the cell class conditional based on the column value.
6. Styling Cells with Cell Class Rules
You can apply cell class rules to add styling to cells based on conditions. AG Grid supports expressions syntax for concise code. The documentation provides details on the available expression syntax. We now have a styled grid. Any questions or requests for other ways to update styles?
7. Custom Cell Renderers and Parameters
We can replace the default cell renderers with our own Angular components. First, we generate a new component using the CLI and implement the AG Grid interface. Then, we use our component as a cell renderer in the App component. We can pass parameters to our cell renderers to make them reusable. By defining an interface for our cell component, we can parameterize and customize the rendering.
8. Using Cell Renderer Selector
We can use components to display different values based on row data. By using a cell renderer selector, we can dynamically switch between different components. For example, we can have an 'over' component for ages over 25 and an 'under' component for ages below 25. This demonstrates the power of using AG Grid to customize and work within Angular.
9. Passing Components to Column Definitions
One limitation of passing components directly to column definitions is that you might want to store them on a server or dynamically retrieve them. To make columns JSON serializable, you can apply a mapping using a components object. Instead of using the actual component, you give it a string identifier. This allows you to separate components from column definitions.
10. Exploring Filters and Custom Filter Implementation
We've explored different filters available in AG Grid, including text, number, and date filters. We enabled the number filter for our medals and the date filter for our dates. We also learned how to handle string dates by providing a comparator function. Additionally, we discussed the floating filter, which allows users to easily filter data by typing in the header. Lastly, we mentioned the possibility of creating a custom filter implementation for specific columns.
11. Implementing the Filter Component
We're going to implement the filter component, which will have a radio button to filter data based on age being either under 25 or over 25. The filter logic checks whether the age is greater than or equal to 25 when the 'isOverTheLimit' property is set to true. If 'isOverTheLimit' is explicitly set to false, the logic checks if the age is less than 25. The 'getModel' method returns the current state of the filter, and the 'setModel' method initializes the filter based on the provided model. The 'filterChanged' callback is called when the radio buttons are clicked, updating the filter model. However, the filter is not yet functional, and we need to use the 'params' object to implement the 'filterChanged' callback.
12. Custom Filter State and Restoration
We can update filters and save their state or preferences. By retrieving and setting the filter model, we can store and restore filter states. We can get an empty object as the filter model, set specific values, and see the changes reflected. The filter model contains information about the filter type and its value. We can save the filter state to local storage and restore it when needed. However, there seems to be an issue with the filtering not working correctly. Let me know if you want me to continue debugging or move on to the next features.
13. Exploring AG Grid Enterprise Features
To access the Enterprise Features of AG Grid, you need to install the AG Grid Enterprise package and import AGGrid Enterprise in your application. These features include right-click options to copy data, export to CSV or Excel, server-side row data, set filters, grouping and pivoting, import and export functionalities, tool panels, sidebars, and aggregations. By setting properties like 'row group panel show' and 'enable row group', you can enable row grouping and aggregate functions. You can also enable charts and range selection. Please note that a license is required for the Enterprise Features.
14. Charting, Grid Options, and Sidebar Features
You can enable charting in AG Grid, allowing you to analyze and display data in different ways. This feature provides flexibility to your users and integrates charting functionality into the grid. If you have any specific features you're interested in, please let me know. Otherwise, I'll continue demonstrating more enterprise features. One way to clean up your Angular component is by using the grid options property, which has the same interface as the component itself. By defining the grid options separately, you can reuse settings and make your code more organized. Another enterprise feature is the sidebar, which allows you to move columns and apply filters to the grid.
15. Exploring Advanced Grid Features
You can use row grouping and pivoting as alternative ways to interact with the grid. AG Grid provides a tool panel component that allows you to customize the grid's functionality. You can add your own custom components and incorporate live examples from the documentation. The sidebar and status bar are additional enterprise features that provide useful options for organizing and aggregating data.
16. Exploring Aggregation and Enterprise Features
The aggregation component provides tools for advanced grid functionality, such as filtering, aggregation, and exporting data. These features enhance the grid's power and eliminate the need for manual copying and exporting. The grid offers a wide range of built-in capabilities, especially in the enterprise versions.
17. Customizing Context Menu and Adding Rows
I'm wondering if anyone has specific projects or issues with AG Grid that I can help with. Let's explore adding new rows to the data set by customizing the context menu. We can duplicate a row when a specific option is clicked. By using the transaction API, we can update the grid's current state and add the duplicated row at the desired index.
18. Accessing Data and Concluding Workshop
We've demonstrated how to use context menus and external methods to access and update data in the grid. Additionally, we showcased the pagination feature and the powerful quick filter, which allows users to search and filter across all columns simultaneously. We also discussed implementing the quick filter using Angular and demonstrated its functionality. If there are no specific requests, we can conclude the workshop as there are other ways to access our documentation.
