Manually creating a Table Layout Panel

Last Modified: 2012-08-13
Hi, can someone help me out with this one?
I'm trying to manually create a table on a custom user control.
Here's my code,

        private void button1_Click(object sender, EventArgs e)
            // Create new table layout
            TableLayoutPanel tbl = new TableLayoutPanel();

            // Set table borderstyle
            tbl.CellBorderStyle = TableLayoutPanelCellBorderStyle.OutsetDouble;

            // Set number of columns
            tbl.ColumnCount = 8;

            // Set number of rows
            tbl.RowCount = 1;

            // Set growstyle
            tbl.GrowStyle = TableLayoutPanelGrowStyle.AddColumns;

            // Set padding
            tbl.Padding = new Padding(3, 3, 3, 3);

            // Set margin
            tbl.Margin = new Padding(0, 0, 0, 0);

            // Row 0
            tbl.RowStyles[0].SizeType = SizeType.Percent;
            tbl.RowStyles[0].Height = 100;

            // Column 0 - Javascript icon
            tbl.ColumnStyles[0].SizeType = SizeType.Absolute;
            tbl.ColumnStyles[0].Width = 22;

            // Column 1 - Status label
            tbl.ColumnStyles[1].SizeType = SizeType.Percent;
            tbl.ColumnStyles[1].Width = 100;

            // Column 2 - Progress Bar
            tbl.ColumnStyles[2].SizeType = SizeType.AutoSize;

            // Column 3 - User
            tbl.ColumnStyles[3].SizeType = SizeType.AutoSize;

            // Column 4 - Ip
            tbl.ColumnStyles[4].SizeType = SizeType.Absolute;
            tbl.ColumnStyles[4].Width = 94;

            // Column 5 - SSL
            tbl.ColumnStyles[5].SizeType = SizeType.Absolute;
            tbl.ColumnStyles[5].Width = 20;

            // Column 6 - GPRS
            tbl.ColumnStyles[6].SizeType = SizeType.Absolute;
            tbl.ColumnStyles[6].Width = 20;

            // Column 7 - LAN
            tbl.ColumnStyles[7].SizeType = SizeType.Absolute;
            tbl.ColumnStyles[7].Width = 20;

            // Add table layout panel

            // Position the table
            //tbl.Location = new Point(0, 0);


When I click my button I'm getting the following error:
