I couldn't find a single code example on this and was confused. I saw something somewhere that lead me to believe that this property was a reference to the control within the cell. Setting the actual cell did the trick.

I.e.:  _activeRow.Cells["Progress"] = e.Percent;

I don't see any code here that sets the value of the progress bar cell. You seem to be setting the value on the EditorResolved of the cell instead of the Value property on the cell itself. Why are you doing that?

I tried doing this, but my progress bar only shows 0% and will not update.

Code fragments are as follows (with the last event handler method the attempt to update the value):

private void InitializeComponents
{
   [...]
   ultraGridColumn9.EditorControl = this.ultraProgressBar1;
   ultraGridColumn9.Header.VisiblePosition = 8;
   ultraGridColumn9.MaxValue = 100;
   ultraGridColumn9.MinValue = 0;
   [...]
}

delegate void ProcessNewAddDelegate();

// this is called when a new backup request is added to the grid
private void ProcessNewAdd()
{
   lock (this)
   {
      foreach (UltraGridRow row in grdStatus.Rows)
      {
         _activeRow = row;
         if (row.Cells["Status"].Text.ToUpper() == "PENDING")
         {
            row.Selected = true;
            string dbname = _tablename[row.Cells["DBName"].Text];
            string backupsetname = row.Cells["BackupName"].Text;
            row.Cells["Status"].Value = "Active";

            Backup(dbname, backupsetname);

            row.Cells["Status"].Value = "Completed";
            row.Cells["End"].Value = DateTime.Now;
           grdStatus.UpdateData();
          _capturesList[0].Save();
         }
      }
   }
}

private void Backup(string dbname, string backupsetname)
{
   BackupDeviceItem bdi = default(BackupDeviceItem);
   Database db = default(Database);

   db = _server.Databases[dbname];
   bdi = new BackupDeviceItem(@"\CARDbackup\" + backupsetname + ".bak", DeviceType.File);

   Backup bk = new Backup();
   bk.Action = BackupActionType.Database;
   bk.BackupSetDescription = "Full backup of " + dbname;
   bk.BackupSetName = backupsetname;
   bk.Database = dbname;
   bk.Devices.Add(bdi);
   bk.Incremental = false;
   bk.LogTruncation = BackupTruncateLogType.Truncate;
   bk.Initialize = true;

   // setting up event handler for backup progress
   bk.PercentCompleteNotification = 10; 
   bk.PercentComplete += new PercentCompleteEventHandler(rs_PercentComplete);
   bk.Complete += new ServerMessageEventHandler(rs_Complete);

   bk.SqlBackup(_server);

   bk.Devices.Remove(bdi);
   bk.PercentComplete -= new PercentCompleteEventHandler(rs_PercentComplete);
}

private void rs_PercentComplete(object sender, PercentCompleteEventArgs e)
{
   // SMO sending backup completion progress event here... not working!
   _activeRow.Cells["Progress"].EditorResolved.Value = e.Percent;
}

The Value of the progressbar inside the cell comes from the value of the cell. So the column's DataType probably need to be an integer in this case. You may also need to set the MinValue and MaxValue properties on the grid column to provide the range of the progress bar.

I can't quite figure out how to update the values in the progressbar control. Can you provide a code snippet on how to do this?
