Hello,
You need to end edit of both DataGrid and BindingContext in the Closing
event handler. Here is a sample code:
private void Form1_Closing(object sender,
System.ComponentModel.CancelEventArgs e)
{
//Call EndEdit() on the datagrid
dataGrid1.EndEdit(null, dataGrid1.CurrentRowIndex, false);
//Call EndCurrentEdit() on the binding context
dataGrid1.BindingContext[dataGrid1.DataSource,
dataGrid1.DataMember].EndCurrentEdit();
Console.WriteLine(dataSet1.HasChanges().ToString());
}
I hope this helps you.
