The UltraCombo control can be used as the UltraGridColumn.ValueList of an UltraGrid column, but it is intended for use as a standalone control on a form. To provide a multi-column dropdown list in a grid cell, use the UltraDropDown control.
The UltraCombo is populated by binding it to a data source, just like the UltraGrid. So use the UltraGridBase.SetDataBinding method, or the UltraGridBase.DataSource and UltraGridBase.DataMember properties.
Be sure to set the UltraDropDownBase.ValueMember property to determine which column in the dropdown is associated with the Value of the UltraCombo.
Optionally, you may also want to set the UltraDropDownBase.DisplayMember property to display more user-friendly text, instead of displaying the value.
Note that the UltraCombo control requires a container (such as a Form or UserControl) in order to function properly. Placing the control on a form (or UserControl) at design-time is sufficient for this, but if the control is created at run-time in code, be sure to add the UltraCombo to the form's (or UserControl's) Controls collection.
