Setting a GcComboBox Cell
Spread Windows Forms 12.0 Product Documentation > Developer's Guide > Customizing Interaction with Cell Types > Working with Graphical Cell Types > Setting a GcComboBox Cell

You can use a GcComboBox cell to display a drop-down list and allow the user to choose items from the list. The GcComboBox cell also has a resize icon in the lower, right corner of the drop-down.

You can specify colors for each item in the combo cell or you can apply an item template. You can add items to the list with the Add method or add items by setting a data source. The GcComboBox cell also supports automatic completion.

Refer to the GcComboBoxCellType class for a complete list of properties and methods.


This example creates a GcComboBox cell.

Copy Code
GrapeCity.Win.Spread.InputMan.CellType.GcComboBoxCellType gccombo = new GrapeCity.Win.Spread.InputMan.CellType.GcComboBoxCellType();
gccombo.Items[0].BackColor = Color.Beige;
gccombo.Items[1].BackColor = Color.Cornsilk;
gccombo.Items[2].BackColor = Color.PeachPuff;
fpSpread1.Sheets[0].Cells[0, 0].CellType = gccombo;
Copy Code
Dim gccombo As New GrapeCity.Win.Spread.InputMan.CellType.GcComboBoxCellType()
gccombo.Items(0).BackColor = Color.Beige
gccombo.Items(1).BackColor = Color.Cornsilk
gccombo.Items(2).BackColor = Color.PeachPuff
