[c#] Changing datagridview cell color dynamically

Implement your own extension of DataGridViewTextBoxCell and override Paint method like this:

class MyDataGridViewTextBoxCell : DataGridViewTextBoxCell
{
    protected override void Paint(Graphics graphics, Rectangle clipBounds, Rectangle cellBounds, int rowIndex,
        DataGridViewElementStates cellState, object value, object formattedValue, string errorText,
        DataGridViewCellStyle cellStyle, DataGridViewAdvancedBorderStyle advancedBorderStyle, DataGridViewPaintParts paintParts)
    {
        if (value != null)
        {
            if ((bool) value)
            {
                cellStyle.BackColor = Color.LightGreen;
            }
            else
            {
                cellStyle.BackColor = Color.OrangeRed;
            }
        }
        base.Paint(graphics, clipBounds, cellBounds, rowIndex, cellState, value,
            formattedValue, errorText, cellStyle, advancedBorderStyle, paintParts);
}

}

Then in the code set CellTemplate property of your column to instance of your class

columns.Add(new DataGridViewTextBoxColumn() {CellTemplate = new MyDataGridViewTextBoxCell()});
