I have this code
Infragistics.Win.UltraWinListBar.Group grp = this.ultraListBar1.Groups.Add(dr["Name"].ToString(), dr["Caption"].ToString());
grp.Items.AllowDuplicateKeys = true;
but AllowDuplicateKeys is read-only and I can't find any property that will allow me to set this, any ideas of what property to set to allow this? Thank you, Jamie
That property is inherited from a base class and is meant to be set. The UltraWinListBar does not allow the addition of duplicate keys.
On a side note, I recommend that you use the UltraWinExplorerBar instead with the explorerbar.Style property set to Listbar. The UltraWinListBar is an older control. The UltraWinExplorerBar is its replacement.
