UltraCombo requires a DataSource. So if you just want to put in a few simple values like this, I recommend using the UltraDataSource component as the data source of the Combo. You would create the UltraDataSource, add a couple of columns to the Band and populate them with data. Then set the ValueMember and DisplayMember on the combo to the appropriate fields. 

Hi,

I'm trying to add these values in an UltraCombo named "ucMatched", how can i do this in C# ?

Thx a lot !

Of course it exists Ctype, but when I compile my code, it says it's an impossible conversion of type.

I look for another thing, and I come back.

PS : thank U 4 your Help

 the problem is here:

Dim ds As DataSet = MyBase.DataSource

o think there is a function in VB CType() that mask from one type to another check MSDN for it 

I've a problem (my code is in VB)

Public Sub AddItem(ByVal Item As String)

Dim ds As DataSet = MyBase.DataSource
Dim dr As DataRow = ds.Tables(0).NewRow

ds.Tables(0).Rows.Add(dr)
dr(0) = "1"
dr(1) = "New Item"

Can't convert from object to Dataset.
