How to bind CheckBoxes to a bidimensional array in WPF? - wpf

Question

I'm new to WPF, so please be patient with me. I have a bidimensional int array (8x8), a uniform grid (8 rows and 8 columns). In each cell of my grid there is a CheckBox. When I click on a checkbox I wish that the corresponding element in my array to change from "0" to "1". When I uncheck again the CheckBox, I wish that this change be reflected in my array.
Further, I will take each row from in my int[8,8] matrix (for example 10010101 - first checkbox in the uniform grid is checked, the second is not checked and so on), convert it to a decimal number and send it over the serial port when I click a button.
Then I want to change the sending process ( process all 8 rows and send the data) in such way that it takes place every time I click on a checkbox from my grid.
I'm stucked with the Bindings.
I hope someone can give me an advice on how should I to do this.
This is my XAML code. Somehow I succeeded to make a binding for my first CheckBox but I'm not understanding well why it's working and If I did the best coding. If I continue in this way I should create a property for every element in my array and I'm sure this is not the right way to do it (because I hardcoded data[0,0]).

</Grid.ColumnDefinitions>
<Button x:Name="btnSetTrue" VerticalAlignment="Center" Grid.Column="0" Content="Set _True" Margin="5" Click="btnSetTrue_Click" ></Button>
<Button x:Name="btnSetFalse" VerticalAlignment="Center" Grid.Column="1" Content="Set _False" Margin="5" Click="btnSetFalse_Click" ></Button>
</Grid>
</Grid>
</Window>
This is my code behind:
using System;
using System.Windows;
using System.Windows.Controls;
using System.ComponentModel;
namespace CheckBox_Matrix_Binding
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
private DataMatrix _dataMatrix = new DataMatrix() ;
public bool _DataMatrixProperty
{
get { return _dataMatrix.DataProperty; }
set
{
_dataMatrix.DataProperty = value;
}
}
public MainWindow()
{
InitializeComponent();
checkBoxGrid.DataContext = _dataMatrix;
}
private void ChekBox0_Checked(object sender, RoutedEventArgs e)
{
}
private void btnSetTrue_Click(object sender, RoutedEventArgs e)
{
_dataMatrix.DataProperty = true;
}
private void btnSetFalse_Click(object sender, RoutedEventArgs e)
{
_dataMatrix.DataProperty = false;
}
}
//THe class DataMatrix implements INotifyPropertyChanged interface
public class DataMatrix: INotifyPropertyChanged
{
public event PropertyChangedEventHandler PropertyChanged;
private bool[,] data;
public bool DataProperty //this is a property
{
get { return data[0, 0]; }
set {
data[0, 0] = value;
OnPropertyChanged("DataProperty");
}
}
public DataMatrix()
{
data = new bool[3, 3];
}
public void OnPropertyChanged(string propertyName)
{
if (PropertyChanged != null)
{
PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
}
}
}
}
Should I use another approach?
Thankyou in advance :)
