C# DataGridView - Add Row Dynamically (bounded datasource)

[lorentz]

Goo day.

I'm working on a C# application and on this particular form, I have a datagridview control that is bounded to a datasource on load. I've implement a drag-drop event to the datagridview, but I cannot 'add' a row to the form and display the added item!! When I exti the form and open it again, the item i added is displayed! I've gone to severl discussions on this, but nothing has worked so far! I know the data is being saved to the datasource, which is great, but the immediate addition is not realtime. Any advice/comment is appreciated.

1) When a drag drop is done, I add a new item to the datasource list.
Object newObj = new Object();
dsObject.List.Add(newObj);

2) When i try to add a row to the datasource, it does not render on the form. I've tried the following:
DataGridViewRow newRow = null;
DataGridViewComboBoxCell tempCell = new DataGridViewComboBoxCell();
tempCell.Items.Add(<some text here>);
newRow.Cells.Add(tempCell);
myDataGridView.Rows.Add(newRow);

This does not work!!! I thank you in advance for any suggestions.
