User Resizing of Row and Columns in TableLayoutPanel At Runtime!

See more:

C#

I'm "trying" to create a TableLayoutPanel that the user can resize at runtime like the behavior of the SplitContainer. This is a WinForm project...I've found some code that partially does this but it's incomplete. Can someone please help me out here?

Thanks in advance,

This is the code I have so far that comes from a thread I found here on CodeProject. The only thing different that I've done in my own is create a customTableLayoutPanel that inherits from TableLayoutPanel. Here is the link TableLayout Panel resize[^]

public partial class Form1 : Form
{
    bool resizing = false;
    TableLayoutRowStyleCollection rowStyles;
    TableLayoutColumnStyleCollection columnStyles;
 
    public Form1()
    {
        InitializeComponent();
    }
 
    private void Form1_Load(object sender, EventArgs e)
    {
        rowStyles = tableLayoutPanel1.RowStyles;
        columnStyles = tableLayoutPanel1.ColumnStyles;
    }
 
    private void tableLayoutPanel1_MouseDown(object sender, MouseEventArgs e)
    {
        if (e.Button == System.Windows.Forms.MouseButtons.Left)
        {
            resizing = true;
        }
    }
 
    private void tableLayoutPanel1_MouseMove(object sender, MouseEventArgs e)
    {
        if (resizing)
        {
            columnStyles[0].SizeType = SizeType.Absolute;
            rowStyles[0].SizeType = SizeType.Absolute;
            rowStyles[0].Height = e.Y;
            columnStyles[0].Width = e.X;
        }
    }
 
    private void tableLayoutPanel1_MouseUp(object sender, MouseEventArgs e)
    {
        if (e.Button == System.Windows.Forms.MouseButtons.Left)
        {
            resizing = false;
        }
    }
}
