Javascript - Ag-grid-Enterprise expand/collapse all row using button?

To expand or collapse all rows in an Ag-Grid Enterprise grid using a button, you can use the Ag-Grid API methods expandAll() and collapseAll(). You need to access the Ag-Grid instance and call these methods when the button is clicked. Here's how you can do it:

Assuming you have an Ag-Grid instance named gridOptions, and you have a button with the ID expandBtn for expanding rows and another button with the ID collapseBtn for collapsing rows, you can use the following JavaScript code:

<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Ag-Grid Example</title> <link rel="stylesheet" href="https://unpkg.com/ag-grid-community/dist/styles/ag-grid.css"> <link rel="stylesheet" href="https://unpkg.com/ag-grid-community/dist/styles/ag-theme-alpine.css"> </head> <body> <div id="myGrid" style="height: 500px;" class="ag-theme-alpine"></div> <button id="expandBtn">Expand All</button> <button id="collapseBtn">Collapse All</button> <script src="https://unpkg.com/ag-grid-community/dist/ag-grid-community.min.noStyle.js"></script> <script> document.addEventListener('DOMContentLoaded', function() { var gridOptions = { columnDefs: [ { field: 'make' }, { field: 'model' }, { field: 'price' } ], rowData: [ { make: 'Toyota', model: 'Celica', price: 35000 }, { make: 'Ford', model: 'Mondeo', price: 32000 }, { make: 'Porsche', model: 'Boxster', price: 72000 } ] }; var gridDiv = document.querySelector('#myGrid'); new agGrid.Grid(gridDiv, gridOptions); var expandBtn = document.querySelector('#expandBtn'); var collapseBtn = document.querySelector('#collapseBtn'); expandBtn.addEventListener('click', function() { gridOptions.api.expandAll(); }); collapseBtn.addEventListener('click', function() { gridOptions.api.collapseAll(); }); }); </script> </body> </html>

In this example:

  • We create an Ag-Grid instance with some sample data and define column definitions.
  • We create buttons for expanding and collapsing all rows with IDs expandBtn and collapseBtn, respectively.
  • We add event listeners to these buttons. When the buttons are clicked, we call the expandAll() and collapseAll() methods on the Ag-Grid API via gridOptions.api.
  • gridOptions.api is the API object of the Ag-Grid instance, which allows us to interact with the grid programmatically.

Examples

  1. JavaScript code to expand all rows in Ag-Grid using a button:

    • Description: Implementing a button functionality to expand all rows in Ag-Grid can enhance user experience by providing a quick way to view all data at once.
    function expandAllRows() { gridOptions.api.forEachNode((node) => { node.setExpanded(true); }); }

  2. JavaScript code to collapse all rows in Ag-Grid using a button:

    • Description: Enabling users to collapse all rows with a single click ensures better control over the displayed data, especially in scenarios with large datasets.
    function collapseAllRows() { gridOptions.api.forEachNode((node) => { node.setExpanded(false); }); }

  3. How to add a button to expand/collapse all rows in Ag-Grid using JavaScript:

    • Description: Integrating a button within the Ag-Grid interface allows users to effortlessly toggle between expanded and collapsed states, improving accessibility and usability.
    <button onclick="expandAllRows()">Expand All</button> <button onclick="collapseAllRows()">Collapse All</button>

  4. Implementing expand/collapse functionality for Ag-Grid rows using JavaScript:

    • Description: By providing expand/collapse functionality, users can customize their view of data, focusing on specific sections of interest while maintaining an organized display.
    // Function to toggle row expansion function toggleRowExpansion(rowIndex) { const node = gridOptions.api.getRowNode(rowIndex); node.setExpanded(!node.expanded); }

  5. Adding expand/collapse buttons to Ag-Grid rows with JavaScript:

    • Description: Enhance user interaction by incorporating intuitive buttons directly within each row of the Ag-Grid, enabling users to expand or collapse individual rows as needed.
    // Define cell renderer for expand/collapse buttons function expandCollapseCellRenderer(params) { const button = document.createElement('button'); button.innerHTML = params.node.expanded ? 'Collapse' : 'Expand'; button.addEventListener('click', function () { toggleRowExpansion(params.node.rowIndex); }); return button; } // Column definition for expand/collapse buttons const columnDefs = [ { headerName: '', cellRenderer: expandCollapseCellRenderer, width: 80 } // Other column definitions... ];

  6. Customizing Ag-Grid to expand/collapse all rows via button click:

    • Description: Tailoring the Ag-Grid interface to include dedicated buttons for expanding and collapsing all rows simplifies navigation and improves user engagement.
    <button onclick="expandAllRows()">Expand All Rows</button> <button onclick="collapseAllRows()">Collapse All Rows</button>

  7. JavaScript function to expand all rows in Ag-Grid without Ag-Grid Enterprise:

    • Description: Implementing row expansion functionality without Ag-Grid Enterprise features ensures compatibility across different versions and reduces dependency on specific libraries.
    function expandAllRows() { const allNodes = gridOptions.api.getModel().rowsToDisplay; allNodes.forEach((node) => { node.setExpanded(true); }); }

  8. JavaScript code snippet to collapse all rows in Ag-Grid without using Ag-Grid Enterprise:

    • Description: Providing an alternative method to collapse all rows in Ag-Grid without relying on enterprise features maintains flexibility and accessibility for a wider range of users.
    function collapseAllRows() { const allNodes = gridOptions.api.getModel().rowsToDisplay; allNodes.forEach((node) => { node.setExpanded(false); }); }

  9. How to create a button to toggle expand/collapse all rows in Ag-Grid using JavaScript:

    • Description: Offering a single button to toggle between expanding and collapsing all rows streamlines user interaction and optimizes space within the interface.
    <button onclick="toggleExpandCollapse()">Toggle Expand/Collapse</button>

  10. JavaScript function to toggle expand/collapse all rows in Ag-Grid on button click:

    • Description: Simplifying user actions by enabling them to toggle between expanding and collapsing all rows with a single button click enhances usability and efficiency.
    let allRowsExpanded = false; function toggleExpandCollapse() { if (allRowsExpanded) { collapseAllRows(); } else { expandAllRows(); } allRowsExpanded = !allRowsExpanded; }
