    Hi, I am newbie to developing a windows application using C#.

    In that index page, when a first textbox text changed, it should automatically add a new field below the first textbox. And if the second textbox ( child control)text changed, it should automatically add a new field below the second textbox. This will go until the last text field doesn't change.
    The textbox created so far, but i cannot set the position for the child controls...its merged.. Have to give the dynamic X,Y points but my code not crossing the level.

    I tried the below code.

    public partial class Form1 : Form
            int x = 8;
            int y = 8;
            public Form1()
            private void Form1_Load(object sender, EventArgs e)
                TextBox txtBox = new TextBox();
                txtBox.Name = "TextBoxName";
                txtBox.Location = new Point(x, y);
                txtBox.TextChanged += new EventHandler(this.TextBox_TextChanged);
            private void TextBox_TextChanged(object sender, System.EventArgs e)
                int n = 2;
                for (int i = 1; i < n; i++)
                    TextBox tb = new TextBox();
                    tb.Location = new System.Drawing.Point(8, 8 + i * 20);
                    tb.Name = "TextBoxName" + i.ToString();
                    tb.Size = new System.Drawing.Size(184, 20);
                    tb.TabIndex = i + 2;                
            private void IterateThroughChildren(Control parentControl)
                foreach (Control childControl in parentControl.Controls)
                    // Find a Particular Control by its Type
                    if (childControl.GetType().ToString().Equals("System.Windows.Forms.TextBox"))
                        childControl.TextChanged += new EventHandler(this.TextBox_TextChanged);
                    if (childControl.HasChildren)
    Any help would be most appreciated.
