Ag Grid Community Version v32.0.0: The Filter Fiasco

Are you one of the many Ag Grid enthusiasts who upgraded to version v32.0.0, only to find that your filtering functionality has gone haywire? You’re not alone! The latest community version of Ag Grid has brought about a host of changes, but one particular issue has left many developers scratching their heads. In this article, we’ll delve into the problem, explore its causes, and provide you with solutions to get your filtering back on track.

The Problem: filter = true and the Grid Breaks

When you set filter = true in your Ag Grid configuration, you expect the grid to enable filtering for your data. However, with version v32.0.0, this simple configuration change can cause the entire grid to break. The symptoms may vary, but common issues include:

• The grid not rendering at all
• Filters not being applied correctly
• Data not being displayed
• Error messages galore!

Before we dive into the solutions, let’s take a step back and understand what’s changed in v32.0.0 that’s causing this issue.

What’s New in Ag Grid v32.0.0?

  
    Ag Grid v32.0.0 introduced significant changes to the filtering mechanism. The new version now uses a more modular and flexible filtering system, which is great for customization but can be a nightmare for existing implementations.
  

The primary culprit behind the filter = true issue is the introduction of the filterModules property. This property allows you to customize the filtering experience by adding or removing filter modules. Sounds cool, right? However, this new property has created a dependency that can cause the grid to break if not configured correctly.

Solutions to the Filter Fiasco

Don’t worry, we’ve got you covered! To get your filtering working again, follow these steps:

1. Update Your Ag Grid Configuration

   Make sure you’re using the latest version of Ag Grid (v32.0.0 or higher). Then, update your grid configuration to include the filterModules property:

         
           const gridOptions = {
             columnDefs: [...],
             filter: true,
             filterModules: [FiltersModule]
           };
         
       

2. Declare the FiltersModule

   In your component, import the FiltersModule from '@ag-grid-community/filter' and declare it as a provider:

         
           import { FiltersModule } from '@ag-grid-community/filter';
   
           @Component({
             selector: 'app-grid',
             template: ''
           })
           export class GridComponent {
             columnDefs = [...];
             filter = true;
             filterModules = [FiltersModule];
           }
         
       

3. Verify Your Filter Configuration

   Double-check your filter configuration to ensure it’s correctly set up. Make sure you’re using the correct filter types and that your filterParams are correctly defined:

         
           const columnDefs = [
             {
               field: 'athlete',
               filter: 'agTextColumnFilter'
             },
             {
               field: 'age',
               filter: 'agNumberColumnFilter',
               filterParams: {
                 buttons: ['reset', 'apply']
               }
             }
           ];
         
       

Troubleshooting Tips

If you’re still experiencing issues after updating your configuration, here are some additional troubleshooting tips:

• Check your browser console for error messages
• Verify that you’re using the correct Ag Grid version (v32.0.0 or higher)
• Ensure that your filterModules are correctly imported and declared
