Navigating through a grid of panels

Question

I'm trying to make a little project in C# using a small grid of panels and four direction buttons as shown here:

But I don't know how to create an easy navigation system using those panels. The "character" is just a colored panel. All the panels are named like their coordinates with a in front of them (p11 to p66) Is there a way to do some kind of function that could take a position of the "character" and color the panel on the same position?

Example

int coords = 21;

private void Up_Click(object sender, EventArgs e)
{
    Move(10);
}

Void Move(int coordchange)
{
    pcoords.BackColor = Color.White;
    coords = coords + coordchange
    pcoords.BackColor = Color.Black;
}

The pcoords part is supposed to be the panel you are currently on. That is the part that I don't know how to make.

Answer 1

public class Panels
{
     public Panel[, ] PanelsArray=new Panel[6,6] ;
     int xcoordinate;
     int ycoordinate;
     public Panel CurrentPanel{get{return PanelsArray[xcoordinate,ycoordinate];}
     public void MoveUp()
     {
         BeforeMove();
         if(ycoordinate>0) ycoordinate--;
         OnMove();
     }
     //declare MoveDown, MoveLeft and MoveRight similiarly
     ...
     private void BeforeMove()
     {
         CurrentPanel.BackColor=Color.White;
     }
     private void OnMove()
     {
        CurrentPanel.BackColor=Color.Black;
     }
}

Then in the form class

public partial class Form1 : Form
{
    public Panels Panels=new Panels();
    public Form1()
    {
            InitializeComponent();
            Panels.PanelsArray[0,0]=p00;
            PanelsPanelsArray[1,0]=p10;
            Panels.PanelsArray[2,0]=p20;
            //...
            Panels.PanelsArray[5,5]=p55;

    }
...

You will probably want to add in code to set the starting colours and coordinates.
