Need code for Combobox SelectedIndexChanged-event

Dear Experts,

I want to try to make a Character Map just like Windows has. I have a combobox on my
form to get the System Fonts and I have used a DataGridView to display the characters.
Now only thing I need is to program the SelectedIndexChanged-event to display the
characters in DataGridView which belongs to the fontname when the user selects a font in the combobox. I have searched and found only vb-code that I don't understand. Who can help me?

        private const int NoOfCols = 16;
        private const int ColWidth = 24;

        public CharMap()
        {
            InitializeComponent();
        }

        private void CharMap_Load(object sender, EventArgs e)
        {
            //Set txtCopyChar as focus
            this.ActiveControl = txtCopyChar;

            //Get a list of font names into combo box.
            InstalledFontCollection fc = new InstalledFontCollection();
            foreach (FontFamily Item in fc.Families)
            {
                cboFontName.Items.Add(Item.Name);
            }
            cboFontName.SelectedIndex = 0;

            //Setup datagrid
            SetupDataGrid();
            //Select the first item
            CharGrid[1, 0].Selected = true;
        }

        private void SetupDataGrid()
        {
            //Number of columns to create.
            CharGrid.ColumnCount = NoOfCols;

            foreach (DataGridViewColumn Column in CharGrid.Columns)
            {
                //Set column width.
                Column.Width = ColWidth;
            }

            //Add rows
            CharGrid.Rows.Add(14);

            //Add chars to data grid
            AddCharsToGrid(0, 32);
            AddCharsToGrid(1, 48);
            AddCharsToGrid(2, 64);
            AddCharsToGrid(3, 80);
            AddCharsToGrid(4, 96);
            AddCharsToGrid(5, 112);
            AddCharsToGrid(6, 128);
            AddCharsToGrid(7, 144);
            AddCharsToGrid(8, 160);
            AddCharsToGrid(9, 176);
            AddCharsToGrid(10, 196);
            AddCharsToGrid(11, 208);
            AddCharsToGrid(12, 224);
            AddCharsToGrid(13, 240);

        }

        private void AddCharsToGrid(int Row, int Index)
        {
            for (int Counter = 0; Counter <= 15; Counter++)
            {
                CharGrid[Counter, Row].Value = (char)(Index + Counter);
            }
        }
