Combobox in a grid cell
The control type of a cell is a part of the cell style that is determined by the GridStyleInfo.CellType property. To have a ComboBox cell in a grid, set the cell type to ComboBox. The items in the ComboBox are held in the style’s DataSource property.
C#
//String collection to set the data source/choice list for the ComboBox
StringCollection items = new StringCollection();
items.Add("One");
items.Add("Two");
items.Add("Three");
items.Add("Four");
items.Add("Five");
//Set the cell type as ComboBox cell.
gridControl1[2, 3].CellType = "ComboBox";
//Set datasource for the combobox cell
gridControl1[2, 3].DataSource = items;
gridControl1[2, 3].CellValue = "Five";
gridControl1[2, 3].ExclusiveChoiceList = true;
//By using StyleInfo
GridStyleInfo style = new GridStyleInfo();
//Set cell type as ComboBox cell.
style.CellType = "ComboBox";
style.DataSource = items;
style.CellValue = "Five";
//Apply ComboBox cell style usign ChangeCels method
gridControl1.ChangeCells(GridRangeInfo.Cell(2, 4), style);
VB
'String collection to set the data source/choice list for the ComboBox
Dim items As New StringCollection()
items.Add("One")
items.Add("Two")
items.Add("Three")
items.Add("Four")
items.Add("Five")
'Set the cell type as ComboBox cell.
gridControl1(2, 3).CellType = "ComboBox"
'Set datasource for the combobox cell
gridControl1(2, 3).DataSource = items
gridControl1(2, 3).CellValue = "Five"
gridControl1(2, 3).ExclusiveChoiceList = True
'By using StyleInfo
Dim style As New GridStyleInfo()
'Set cell type as ComboBox cell.
style.CellType = "ComboBox"
style.DataSource = items
style.CellValue = "Five"
'Apply ComboBox cell style usign ChangeCels method
gridControl1.ChangeCells(GridRangeInfo.Cell(2, 4), style)

Note:
The GridCellTypeName class has the collection of properties for the cell types. By using the ChoiceList property, you can also set the source to the ComboBox.

C#: ComboBoxCell
