The issue with unchecked checkboxes or radio buttons in a jqxGrid that occurs when scrolling is likely related to the way the jqxGrid handles its virtual scrolling feature. jqxGrid is a powerful JavaScript grid control, but it has certain behavior quirks that might require additional handling.

When using virtual scrolling in the jqxGrid, only the visible rows are actually rendered in the DOM to improve performance. As you scroll, rows that move out of the viewport are removed from the DOM and new rows are added. This behavior can lead to issues with form elements (such as checkboxes and radio buttons) losing their states when they are outside the viewport and then reappear later.

To address this issue, you need to consider two main factors:

  1. Data Binding and Persistence: Ensure that the data binding for the checkboxes and radio buttons in the grid is set up correctly. When you scroll, the data in the grid should be retained so that the state of the checkboxes and radio buttons is correctly restored when the rows are re-rendered.

  2. Handling Scroll Events: Implement event handlers to handle the scroll events of the jqxGrid. When a scroll event occurs, you can update the state of the checkboxes and radio buttons to ensure their values persist as you scroll.

Here's a general outline of what you can do to handle the scroll events in jqxGrid:

  1. Set Up the Grid Configuration: Ensure that the jqxGrid is correctly configured with data binding, including the use of checkboxes and radio buttons in the columns.

  2. Implement Scroll Event Handler: Add a scroll event handler to the jqxGrid to handle the scroll events. You can do this using the onScroll event of the jqxGrid.

  3. Update Checkbox/Radio Button State: In the scroll event handler, update the state of the checkboxes and radio buttons to ensure they persist when rows are re-rendered due to scrolling.

Here's a sample code snippet to give you an idea of how the implementation might look:

javascript
// Assuming you have already configured jqxGrid with checkboxes and radio buttons // ... // Get a reference to the jqxGrid instance const grid = $('#jqxgrid').jqxGrid('getInstance'); // Add a scroll event handler to the jqxGrid grid.on('scroll', (event) => { // Update the state of the checkboxes and radio buttons here // ... });

Note: The specific implementation details may vary based on your application's requirements and how you've configured the jqxGrid. You may need to adjust the code according to your use case.

Additionally, consider checking the jqxGrid documentation and community forums for any specific solutions or examples related to handling checkboxes and radio buttons with virtual scrolling. jqxGrid has a strong community and you might find relevant discussions and examples to address your particular issue.
