BackColor Property (Cell)
Example 


Gets or sets the background color for a cell.
Syntax
'Declaration
 
Public Property BackColor As Color
'Usage
 
Dim instance As Cell
Dim value As Color
 
instance.BackColor = value
 
value = instance.BackColor
public Color BackColor {get; set;}

Property Value

Color object containing the background color of the cell
Remarks

The setting for this property can be overridden if a named style is assigned to the cell using the StyleName property, and that named style sets the background color.

When cells are locked with the Lock and Protect properties, the value of the SheetView.LockBackColor property overrides the value of this property.

If you use this property to retrieve the background color for a range of cells that do not have the same background color, the background color of the active cell is returned.

This property does not change the background color of the drop-down list portion of a combo box cell. The background color of the drop-down list portion of a combo box cell is always white.

If you are working with button cells, use the CellType.ButtonCellType.ButtonColor property to specify the color of the face of the buttons. If you prefer, you can use alternating background colors for the rows in the spreadsheet by using the AlternatingRow.BackColor property for each alternating row.

Specify the text color for the cell by setting the ForeColor property.

Example
This example generates random background and foreground colors and assigns them to the cells in the sheet.
FarPoint.Win.Spread.Cell acell;
int i, j;
int iColorR = 0;
int iColorG = 0;
int iColorB = 0;
Random rand = new Random();
fpSpread1.ActiveSheet.ColumnCount = 20;
fpSpread1.ActiveSheet.RowCount = 20;
acell = fpSpread1.ActiveSheet.Cells[0, 0];
for (i = 0; i <= fpSpread1.ActiveSheet.RowCount - 1; i++)
{
     for (j = 0; j<= fpSpread1.ActiveSheet.ColumnCount - 1; j++)
     {
          acell = fpSpread1.ActiveSheet.Cells[i, j];
          acell.BackColor = Color.FromArgb(iColorR, iColorG, iColorB);
          acell.ForeColor = Color.FromArgb(iColorB, iColorR, iColorG);
          iColorR = rand.Next(0, 255);
          iColorG = rand.Next(0, 255);
          iColorB = rand.Next(0,255);
     }
}
Dim acell As FarPoint.Win.Spread.Cell
Dim i, j, c As Integer
Dim iColorR, iColorG, iColorB As Integer
FpSpread1.ActiveSheet.ColumnCount = 20
FpSpread1.ActiveSheet.RowCount = 20
For i = 0 To FpSpread1.ActiveSheet.RowCount - 1
     For j = 0 To FpSpread1.ActiveSheet.ColumnCount - 1
          acell = FpSpread1.ActiveSheet.Cells(i, j)
          Randomize()
          iColorR = Int(255 * Rnd()) + 1
          iColorG = Int(255 * Rnd()) + 1
          iColorB = Int(255 * Rnd()) + 1
          acell.BackColor = Color.FromArgb(iColorR, iColorG, iColorB)
          acell.ForeColor = Color.FromArgb(iColorB, iColorR, iColorG)
     Next j
Next i
