I am working with an UltraCombo control.  I have loaded data into the control using the following code:

var table = new DataTable();

var column = new DataColumn("Codes");
table.Columns.Add(column);

DataRow row = table.NewRow();
row["Codes"] = "A";
table.Rows.Add(row);

row = table.NewRow();
row["Codes"] = "B";
table.Rows.Add(row);

row = table.NewRow();
row["Codes"] = "a";
table.Rows.Add(row);

row = table.NewRow();
row["Codes"] = "c";
table.Rows.Add(row);
ultraCombo1.DataSource = table;

Then when a user types in a lower case "a", the combo box selects the upper case "A" from the values, instead of the lower case "a".  If the user types a lower case "b", I really want the combo box to consider that a new value, not select the upper case "B".  

So, I would like the combo box to be case sensitive, but could not find a way to do this.

Is there a property to define this sort of behavior.

Thanks,

Andy
