Angular ag grid example12/12/2023 Setup and configure Angular Grid example project.Some of the best Angular Grid libraries.Here’s how we do it: 'app-numeric-editor-cell', We also need to add the keyDown listener to prevent losing focus when the user presses navigation keys. To do that, we need to add an event listener to the input and check each item typed in by the user. Now we’re ready to implement the functionality to filter out non-numeric characters. Notice that we’re getting the cell value from the grid in the agInit method and returning the value in the getValue method. In Angular we can use the mechanism to accomplish 'app-numeric-editor-cell',Įxport class NumericEditorComponent textInput So we need to access that input to read its value. We want to return the value that a user typed into the input. To do that, it calls the getValue method on our Angular component that should return the result of the editing. Once editing is finished by pressing Enter or removing the focus from the input, ag-Grid needs to get a value from our editor. Now we need to implement some required methods. So let’s import our custom cell renderer and specify it in the configuration: export class AppComponent implements OnInit All custom components should be listed in frameworkComponents configuration option. Now that we have our component, we need to tell ag-Grid about it. It’s a simple component with just one method agInit that is used to receive parameters from ag-Grid. So, create a new file and put the code for our component inside: 'app-number-formatter-cell', To show the formatted value, we’ll use a simple span element. It will receive the value of a cell through the agInit method. The first task is going to be to implement an Angular component. ![]() The component will take advantage of the Angular’s currency pipe to format values. We want to format our number according to a user’s locale, so we need to create a custom component. If you want more complex HTML inside the cells, this can be achieved using cell renderers. By default, the grid will create the cell values using simple text. The job of the grid is to lay out the cells. We will implement three custom components, and add them like this: [ These required methods are defined by interfaces described in the documentation.Īll custom components used by ag-Grid should be listed in the AgGridModule.withComponents method imported into the main application module. A custom column filter should implement the doesFilterPass method that processes values and so on. For example, a cell editor should implement the getValue method that ag-Grid uses to request the value from our component and update the data. There are also some methods that need to be implemented by a component to work with ag-Grid. The UI part is implemented using Angular templates. Our Angular grid is customized by implementing custom Angular components. You can download the sample that we’ll be building in this article from GitHub repository. Our new filter will provide UI to type in the price range and filter out cars that fall out of that range: Custom filter for the “Price” column So we’ll implement a custom cell editor to restrict the input only to numbers: Custom cell editor for the “Price” column Custom filterĪnd we’ll finish this tutorial by implementing a custom filter. By default, when a cell is being edited, users can type in any character. Since the “Price” field is numeric, it can’t contain non-numeric characters. Here’s how the numbers are displayed on my computer: Custom cell renderer for the “Price” column Custom cell editor Custom cell rendererįirst, we’re going to implement a custom cell renderer to show the price formatted according to a user’s locale. This exercise won’t take you longer than 10 minutes. To do that, we’ll implement a custom filter, cell renderer, and cell editor. In this tutorial, we’ll provide more options for a user to work with data in the “Price” column. Our sample application displayed the following data on the screen: Data rendered using Angular grid If you haven’t worked through our previous tutorial and don’t have a sample application now, you can download it from this GitHub repository. In the previous article on how to get started with Angular grid we’ve integrated ag-Grid into an Angular application. You can extend the default functionality by creating new Angular components and integrating them into the datagrid. ag-Grid is very flexible due to its component-based architecture. ![]() We believe that developers should be able to customize the grid easily and implement the functionality to meet their business requirements. Implement custom filtering logic, cell editor and renderer Everything is a customizable component in Angular grid
