How to refresh the data?

hi all,
After I insert one record in a table, i am going to refresh datagrid such that user could see the result, i used this:

Context.Refresh(System.Data.Linq.RefreshMode.OverwriteCurrentValues,Context.TableName);
this.BindingSource.DataSource = Context.TableName;
dataGridViewX1.DataSource = BindingSource ;
alarmBindingSource.ResetBindings(true);

but there is no change and new inserted row is not displayed.

Is there any way except re-new of DataContext(which spends long time)?

Please help.
