Refreshing a DataGridView in Form1 from Form2 in WinForms

In a Windows Forms (WinForms) application, it is common to have a DataGridView in Form1 that displays data from a database or a collection. Often, the data is modified or added in a different form, such as Form2. A frequent requirement is to refresh the DataGridView in Form1 after saving data from Form2. Here, we will discuss a straightforward approach to achieve this.

Understanding the Requirement

When Form2 saves new or updated data, Form1 needs to reflect these changes by refreshing its DataGridView. This can be achieved through several mechanisms like events, delegates, or direct calls to refresh methods.

Solution: Using a Public Method to Refresh Data

One effective method is to create a public method in Form1 that refreshes the DataGridView, and call this method from Form2. Here is a step-by-step guide to implement this solution:

Step-by-Step Implementation

Create a Public Method in Form1

First, ensure Form1 has a public method to refresh the DataGridView. This method could re-fetch data from the database or reset the binding source.

Conclusion

By implementing a public method in Form1 to refresh the DataGridView and calling this method from Form2 after saving data, you ensure the DataGridView always displays the most up-to-date information. This simple and effective approach maintains the decoupling of forms while keeping data synchronized.

Implement this method in your WinForms application to seamlessly update your DataGridView and enhance the user experience.
