I have a combobox with multiple selections and want to create a comma separated list form the selectedvalues.
I have this
Dim sbSp As New StringBuilder()
Dim collectionSp As IList(Of RadComboBoxItem) = ddlUsers.CheckedItems
For Each item As RadComboBoxItem In collectionSp
sbSp.Append(item.Value + ",")
RoomUsers = sbSp.ToString
What this gives me is the correct list but there is always a comma at the end.
What do I need to change to remove the comma.
