Hi All !

Szenario:
By pushing a button a UltraCombo should be filled via a UltraDataSource (which is associated to the UltraCombo).

Problem:
Using UltraDataSource's "AddRange" method does not fill the UltraDataSource and therefore the UltraCombo. 

By the way:  using the UltraDataSource's method  "Add"  works fine.

e.g. this.ultraDataSource1.Rows.Add(new object[ { ((object)("1")), ((object)("Ralf"))});

Source code:
I have simplified the code like this:

//Form1.Designer.cs
private void InitializeComponent(){

 ...
 UltraDataColumn ultraDataColumn1 = new UltraDataColumn("Name");
 UltraDataColumn ultraDataColumn2 = new UltraDataColumn("Nr");
        ultraDataSource1 = new UltraDataSource(this.components);  
        ultraCombo1 = new UltraCombo();
       
// 
// ultraDataSource1
//
this.ultraDataSource1.Band.Columns.AddRange(new object[ {
     ultraDataColumn1,
     ultraDataColumn2});
           

// 
// ultraCombo1
//  
this.ultraCombo1.DataMember = "Band 0";  
this.ultraCombo1.DataSource = this.ultraDataSource1;            
 
ultraGridBand1.Columns.AddRange(new object[ {
             ultraGridColumn1,
             ultraGridColumn2});

this.ultraCombo1.DisplayLayout.BandsSerializer.Add(ultraGridBand1);
this.ultraCombo1.DisplayMember = "Name";         
this.ultraCombo1.ValueMember = "Nr";
}
 
 
 // Form.cs
 private void ultraButton1_Click(object sender, EventArgs e)
         {
             this.ultraDataSource1.Rows.AddRange(new object[ {
             new Infragistics.Win.UltraWinDataSource.UltraDataRow(new object[ {
                         ((object)("Nr")),
                         ((object)("1")),
                         ((object)("Name")),
                         ((object)("Ralf"))}),
             new Infragistics.Win.UltraWinDataSource.UltraDataRow(new object[ {
                         ((object)("Nr")),
                         ((object)("2")),
                         ((object)("Name")),
                         ((object)("Claus"))}),
             new Infragistics.Win.UltraWinDataSource.UltraDataRow(new object[ {
                         ((object)("Nr")),
                         ((object)("3")),
                         ((object)("Name")),
                         ((object)("Georg"))}),
             new Infragistics.Win.UltraWinDataSource.UltraDataRow(new object[ {
                         ((object)("Nr")),
                         ((object)("4")),
                         ((object)("Name")),
                         ((object)("Monika"))})});
            
        }

Any advice or ideas you might have, would be very welcome. Thanks in advance !

Kind regards,

Claus
