Hello,
i make an event handler to call a function when row changed, it seems i did something wrong or still missing and i copied the relative code only to not interrupt you, so please help me.

DataTable TableX= new DataTable();

// do required code to fill the data table and already filled.

TableX.RowChanged += new DataRowChangeEventHandler(Row_Changed);

protected void Row_Changed(object sender, DataRowChangeEventArgs e)
{

MessageBox.Show("changed");
}
