Since I can't give you a sample of the project I'm working on, I created a new project to recreate the issue. Weird enough it's working perfectly fine just the way it's supposed to. Don't know WHERE I went wrong but yeah. Will let you know if I run into any issues.

Sorry about that.

Thanks for following up. Hope it works out.

Thanks Michael. I found where I went wrong btw. Looks like it's working like expected except for one thing.

With the following code, how do I set the DataValue for each member as the OptionSet is linked to the database to get the selected value.

private void DataSource_online01UltraOptionSet()
        {
            // Create a lookup table to be used when the selected item in the UltraOptionSet
            // is changed.  The name of the data source (the key) is used to get the data source
            // object to be bound to the UltraComboEditor.
            //
            this.dataSourcesHashTable = new Hashtable();
            this.dataSourcesHashTable[Strings.ArrayListOfCompletion] = this.arrayListOfCompletion;
            this.dataSourcesHashTable[Strings.ArrayListOfBatch] = this.arrayListOfBatch;

            // Get a sorted list of the keys to be bound to the UltraOptionSet.
            //
            string[] dataSourceMode = new string[2];
            this.dataSourcesHashTable.Keys.CopyTo(dataSourceMode, 0);
            Array.Sort(dataSourceMode);

            this.online01UltraOptionSet.DataSource = dataSourceMode;
        }

Or do I need to set it somewhere else?

Also, another question. In regard to the following code:

#region ArrayList of Completion

            this.arrayListOfCompletion = new ArrayList(3);

            this.arrayListOfCompletion.Add(new Completion(2, supportingNameUltraTextEditor.Text + " and " + originalNameUltraTextEditor.Text + " at entry"));
            this.arrayListOfCompletion.Add(new Completion(3, originalNameUltraTextEditor.Text + " only at entry"));
            this.arrayListOfCompletion.Add(new Completion(6, "No Printing Required"));

            #endregion // ArrayList of Completion

            #region ArrayList of Batch

            this.arrayListOfBatch = new ArrayList(6);

            this.arrayListOfBatch.Add(new Batch(1, supportingNameUltraTextEditor.Text + " at entry, " + originalNameUltraTextEditor.Text + " at batching"));
            this.arrayListOfBatch.Add(new Batch(2, supportingNameUltraTextEditor.Text + " and " + originalNameUltraTextEditor.Text + " at entry"));
            this.arrayListOfBatch.Add(new Batch(3, originalNameUltraTextEditor.Text + " only at entry"));
            this.arrayListOfBatch.Add(new Batch(4, supportingNameUltraTextEditor.Text + " and " + originalNameUltraTextEditor.Text + " at batching"));
            this.arrayListOfBatch.Add(new Batch(5, originalNameUltraTextEditor.Text + " only at batching"));
            this.arrayListOfBatch.Add(new Batch(6, "No Printing Required"));

            #endregion // ArrayList of Batch

Whenever the text on either of the two text boxes is update/changed, how would I now have the change reflect on validated since it's part of the array? I used to use the textbox validated event but obviously I cannot use that now.

The two textboxes in question is: supportingNameUltraTextEditor.Text and originalNameUltraTextEditor.Text
