Change the cell value programatically by doing what, exactly? (show some
code).

The value cannot save back to XML, how exactly? Is an exception being
thrown? (show some code)

1. dgTrack.Rows[Row].Cells["Picture"].Value = Picture;
dgTrack.Rows[Row].Cells["Longitude"].Value = Longitude;
dgTrack.Rows[Row].Cells["Latitude"].Value = Latitude;
dgTrack.Rows[Row].Cells["Radius"].Value = Radius;
dgTrack.Rows[Row].Cells["Audio1"].Value = objAudio.C1;
dgTrack.Rows[Row].Cells["Audio2"].Value = objAudio.C2;

dataSet.WriteXml("setting.xml");
No exception is thrown.

Thanks.

I think you may need to call DataSet.AcceptChanges before WriteXml to make
the edited valus "stick".

Hi Daniel,

I found that I can't write back XML everytime after I use OpenFileDialog to
find a file, otherwise it's OK.

Thanks!
