Solving the object Object Issue in Ag-Grid with Angular 11

If you're working with Ag-Grid in your Angular 11 application, you might encounter a frustrating issue where double-clicking on a row to retrieve its data results in the output [object Object]. This issue can be confusing, especially when you can see the data in the console but are unable to display it properly in your application. In this guide, we'll explain how to address this problem and retrieve the required row data effectively.

The Problem

When you try to access row data upon double-clicking a row, you might implement something like this in your method:

The issue here arises from storing the entire event object instead of just the relevant row data itself. As a result, when you try to display rowsSelection in your HTML, it shows [object Object], which is not informative for users. Instead, you want to access specific fields from that row data.

The Solution

To resolve this issue, you need to focus on directly accessing the data from the event object. Specifically, you can utilize event.node.data to set your rowsSelection. Here's how you can do this:

Step-by-Step Implementation

Modify the onRowDoubleClicked Method:
Update your onRowDoubleClicked method to access the required data directly from the double-click event:

In this step, we are specifically pulling the data from the clicked row's node.

Update Your HTML to Display the Data:
Adjust your HTML to format the output properly. Since now you are storing an object in rowsSelection, consider displaying its properties individually or use JSON stringification for a quick view.

For example, if you want to display the Unit_Code directly:

Or to display the entire rowsSelection as a string:

Conclusion

By accessing the data directly from the event node in your onRowDoubleClicked method, you can resolve the issue of displaying [object Object]. This approach not only resolves the current issue but also helps you gain a better understanding of how to manipulate events within Angular's Ag-Grid. Now you can seamlessly interact with your grid data in a more meaningful way!

Feel free to implement this solution in your project and enhance the way your application handles row selections. Happy coding!
