You need to give us more information with regard to how you are binding the datagrid. Do you bind to a DataTable, DataSet, or a collection of .Net objects? Do you want to update the database as soon as the user is finished entering data, or do you want the user to press a button once they have finished all updates, or what ?

I have bind the DataGrid by using dataset as
DG_Company.ItemsSource = ds_Company.Tables[0].DefaultView;
When i run program my DG_Company datagrid displays all records from dataset.

If i edit some rows from datagrid at that time this changes has to be save in database.

So for this what do i do ?
