Dataview.RowFilter problem - displaying field value  from first row

When I use the dataview.rowfilter and I try to display the field value of
the first row, the code doesn't seem to show the first row AFTER the
rowfilter (it displays the value of the first row of the dataview without the filter).
This is my code:

DataView DataView_Filter = new DataView();
DataView_Filter.Table = DS_States.Tables["Table1"];
sFilter = "Emplcode = '123233'";
DataView_Filter.RowFilter = sFilter;
MessageBox.Show (DataView_Filter.Count.ToString());    //it displays 6 items, which is correct.

MessageBox.Show (DataView_Filter.Table.Rows[0]["Emplcode"].ToString());
//it displays the first item of the initial dataview, not the filtered dataview

How can I display the first item of the filtered dataview? I assume there
must be some method that returns the array index since Rows[0] is not
necessarily the first row of the filtered dataview.

Thanks,
Vaughn

Here is one way to do it:

MessageBox.Show(( (DataRowView) (DataView_Filter)[0]).Row[0].ToString());

Do not use DataView_Filter.Table as it again gets the data from the original table.

After using filter you should only work with the dataview.

But what's the difference between:

MessageBox.Show (DataView_Filter.Table.Rows[0]["Emplcode"].ToString());

and

MessageBox.Show(( (DataRowView) (DataView_Filter)[0]).Row[0].ToString());  ?

I ended up using an IENumerator to go through the resulting dataview but it seems that PastorDwayne's way is easier. Plus, I don't have to add something that rhymes with Terminator.
I know how many rows are in the resulting view so I can just go through it with a loop.
