  Hello,

  Without looking at your code, I cannot predict the exact source of the problem for you, but I can share how you should be creating a Combobox CellType in your Spread Win application.

  Add Combobox Cell Type:```
  
  FarPoint.Win.Spread.CellType.ComboBoxCellType cmbct = new FarPoint.Win.Spread.CellType.ComboBoxCellType();
  
  cmbct.Items = (new String { “Item 1”, “Item 2”, “Item 3”, “Item 4”, “Item 5”, “Item 6” });
  
  fpSpread1.Sheets[0].Cells[1, 1].CellType = cmbct;

  
  [b]Properties that can alter the behavior of Combobox's dropdown button:[/b] To be able to observe proper behavior, when clicking the dropdown button, please ensure that the following properties are defined as follows:```
  cmbct.DoubleClickTextToDropDown = false;
  cmbct.DropDownOptions = FarPoint.Win.DropDownOptions.ButtonAndText;
  fpSpread1.ButtonDrawMode = ButtonDrawModes.Always;
  fpSpread1.ActiveSheet.OperationMode = OperationMode.Normal;
  ```Additionally, I have attached a sample program for your reference. If the above suggestions don't help, you can modify the program and share back for us to investigate.
