Hierarchical Update Problem.

hdv212

Hi i have 2 tables : Persons (master) Images (detail) each person can multiple images. i'm using tableAdapterManager to accomplish this and here is my code in my DataManager class :

public bool SavePersonWithImages(MyDataSet DataSet)
{
bool saved = false;

       if (DataSet.GetChanges() != null)
       {
           try
           {
               MyDataSetTableAdapters.PersonsTableAdapter personAdapter = new MyDataSetTableAdapters.PersonsTableAdapter();
               MyDataSetTableAdapters.ImagesTableAdapter imageAdapter = new MyDataSetTableAdapters.ImagesTableAdapter();
               MyDataSetTableAdapters.TableAdapterManager manager = new MyDataSetTableAdapters.TableAdapterManager();

               manager.PersonsTableAdapter = personAdapter;
               manager.ImagesTableAdapter = imageAdapter;
               int rowAffected = manager.UpdateAll(DataSet);
               saved = (rowAffected > 0);
               DataSet.AcceptChanges();
            }
           catch (Exception ex)
           {
               MessageBox.Show(ex.Message, "Error!", MessageBoxButtons.OK, MessageBoxIcon.Error);
               DataSet.RejectChanges();
           }

       }
       return saved;

}

the insert & delete works fine, but my problem when user edit the image with replace that image with new one, it's works successfully, but when i close the form and open it again, it's don't display image! here is my edit button code :

private void barBtnEditPerson_ItemClick(object sender, ItemClickEventArgs e)
{
if (this.personBindingSource.Count > 0)
{
MyDataSet.PersonRow personCurRow = (MyDataSet.PersonRow)((DataRowView)this.personBindingSource.Current).Row;
FrmZamin frm = new FrmZamin(personCurRow, this.amlakDataSet);
personCurRow.BeginEdit();
if (frm.ShowDialog() == DialogResult.OK)
{
this._frmLoading = new FrmWait("Saving data ...");
personCurRow.EndEdit();
DataManager dm = new DataManager();
dm.SavePersonWithImages(this.myDataSet);
this._frmLoading.Close();
this.backgroundWorker1.RunWorkerAsync();
}
else
{
personCurRow.CancelEdit();
}
this.
