Editing and commiting DataGridView cell changes (bound to a List of Objects)

I have a Windows Forms application which contains a DataGridView inside it. The DataGridView gets populated from a DataSource which is a list of MyClass. MyClass contains a set of properties and a constructor like so:

public class MyClass
{    
    public PropertyA{get;set};
    public ProppertyB{get;set;}
    public ProppertyC{get;Set}
}

Then in the Main form I have a method which returns a List myCollection and a button which populates the DataGridView with "myCollection" like so:

private void btlLoadDataInDataGrid_Click(object sender, EventArgs e)
{                   
    var headers = GetAllHeaders();//GetAllheaders returns a List<MyClass>
    dataGridView1.DataSource = headers;
}

What I get is a DataGridView with the columns from the original MyClass. Now I want to be able to edit the data in the DataGridView and commit this change to the actual list of MyClass properties. Can somebody please advice what would be a best approach to do this?

When you edit your grid whose DataSource is set to a List of objects and change any cell's value, the underlying data in the row is automatically updated. In your case the underlying row data is of type MyClass.

At any point of time you can get the updated row data, using the DataGridView.DataBoundItem property.

Sample code:

foreach(DataGridViewRow item in dataGridView1.Rows)
{
    MyClass rowData = item.DataBoundItem as MyClass;
    if(rowData != null)
    {
        // Do your stuff
    }
}

The data commit logic is different when your grid is populated from a database. You have to write code to commit the changed data to the database.
