JqGrid is a powerful jQuery plugin that enables you to display and interact with tabular data on your website. Sometimes, you may need to refresh the data displayed in a JqGrid to ensure that users are always viewing the most up-to-date information. In this article, we will guide you through the process of refreshing data in a JqGrid.
To refresh the data in a JqGrid, you will first need to have the jqGrid plugin integrated into your project. Once you have set up your grid and loaded your initial data, you can follow these steps to refresh the data:
1. Identify the Grid:
Before you can refresh the data, you need to identify the JqGrid instance you want to refresh. You can do this by using the jQuery selector to target the grid element. For example, if your grid has an id of 'myGrid', you can select it using $('#myGrid').
2. Clear Existing Data:
To refresh the data, you will first need to clear the existing data in the grid. You can do this by calling the 'clearGridData' method on the grid instance. This method will remove all the rows currently displayed in the grid.
3. Reload Data:
After clearing the existing data, you can reload new data into the grid. You can use the 'setGridParam' method to update the grid parameters with the new data source. Make sure to provide the updated data source URL or data object when calling this method.
4. Trigger Reload:
Finally, trigger the reload of the grid by calling the 'trigger' method on the grid instance. This will force the grid to fetch the new data and display it to the users. You should see the updated data reflected in the grid after this step.
Here is a sample code snippet that demonstrates how to refresh the data in a JqGrid:
var myGrid = $('#myGrid');
// Clear existing data
myGrid.jqGrid('clearGridData');
// Reload data
myGrid.jqGrid('setGridParam', { url: 'new-data-source-url' }).trigger('reloadGrid');By following these steps and incorporating them into your code, you can easily refresh the data in a JqGrid whenever necessary. This process ensures that your users always have access to the most current information displayed in the grid.
We hope this guide has been helpful in understanding how to refresh data in a JqGrid. Feel free to experiment with different options and customize the process to suit your specific needs. Happy coding!
