    ButtonDrawMode Property (FpSpread)
    In This Topic
    Gets or sets whether to display buttons in button and combo box cells in the component.
    Syntax
    'Declaration
     
    Public Property ButtonDrawMode As ButtonDrawModes
    'Usage
     
    Dim instance As FpSpread
    Dim value As ButtonDrawModes
     
    instance.ButtonDrawMode = value
     
    value = instance.ButtonDrawMode
    public ButtonDrawModes ButtonDrawMode {get; set;}

    Property Value

    ButtonDrawModes setting that specifies how to display buttons in cells
    Remarks

    Use this property to limit where buttons are displayed in the spreadsheet. You can combine values using the OR logical operator. You can also perform the equivalent of OR-ing by adding the numeric values 1 (current cell), 2 (current column), 4 (current row), 8 (always button), and 16 (always combo box) for the combination you want.

    When the OperationMode property is set to Row Mode, RowMode uses the ButtonDrawMode property. The active row is always painted with a selection bar. The buttons are painted or not painted based on the setting of the ButtonDrawMode property. (Note, in Spread COM, RowMode ignored the ButtonDrawMode property. Before editing the active row, the active row was painted with a selection bar but without buttons. After editing the active row, the active row was painted with buttons but without a selection bar. In Spread for Windows Forms, there is no distinction between before and after editing.)

    Create a button or combo box cell using the ButtonCellType or ComboBoxCellType. class For an overview of these graphical cell types, refer to Working with Graphical Cell Types.

    Example
    This example specifies whether to display a button in a combo box cell.
    FarPoint.Win.Spread.FpSpread fpSpread1 = new FarPoint.Win.Spread.FpSpread();
    FarPoint.Win.Spread.SheetView shv = new FarPoint.Win.Spread.SheetView();
    DialogResult dlg;
    fpSpread1.Location = new Point(10, 10);
    fpSpread1.Height = 200;
    fpSpread1.Width = 400;
    Controls.Add(fpSpread1);
    fpSpread1.Sheets.Add(shv);
    fpSpread1.ActiveSheet.Cells[0, 0].CellType = new FarPoint.Win.Spread.CellType.ComboBoxCellType();
    fpSpread1.ActiveSheet.Cells[1, 0].CellType = new FarPoint.Win.Spread.CellType.ComboBoxCellType();
    fpSpread1.ActiveSheet.Cells[1, 2].CellType = new FarPoint.Win.Spread.CellType.ComboBoxCellType();
    dlg = MessageBox.Show("Do you want to hide the button for the combo box in the third column??", "ButtonDrawMode", MessageBoxButtons.YesNo);
    if (dlg == DialogResult.Yes)
    {
         fpSpread1.ButtonDrawMode = FarPoint.Win.Spread.ButtonDrawModes.CurrentColumn;
    }
    Dim fpSpread1 As New FarPoint.Win.Spread.FpSpread()
    Dim shv As New FarPoint.Win.Spread.SheetView()
    Dim dlg As DialogResult
    fpSpread1.Location = New Point(10, 10)
    fpSpread1.Height = 200
    fpSpread1.Width = 400
    Controls.Add(fpSpread1)
    fpSpread1.Sheets.Add(shv)
    fpSpread1.ActiveSheet.Cells(0, 0).CellType = New FarPoint.Win.Spread.CellType.ComboBoxCellType()
    fpSpread1.ActiveSheet.Cells(1, 0).CellType = New FarPoint.Win.Spread.CellType.ComboBoxCellType()
    fpSpread1.ActiveSheet.Cells(1, 2).CellType = New FarPoint.Win.Spread.CellType.ComboBoxCellType()
    dlg = MessageBox.Show("Do you want to hide the button for the combo box in the third column??", "ButtonDrawMode", MessageBoxButtons.YesNo)
    If dlg = DialogResult.Yes Then
         fpSpread1.ButtonDrawMode = FarPoint.Win.Spread.ButtonDrawModes.CurrentColumn
    End If
