//This block dynamically creates a TextBox and adds it to the form

TextBox tb = new TextBox();

tb.Location = new Point(10, 10);

tb.Text = "Some text";

//Hook our textbox up to our generic textbox handler

tb.TextChanged += new System.EventHandler(this.tb_TextChanged);


//This block dynamically creates a Button and adds it to the form

Button b = new Button();

b.Name = "bTest";

b.Location = new Point(10, 40);

b.Text = "My Button";

//Hook our button up to our generic button handler

b.Click += new System.EventHandler(this.b_Click);



//Our generic textbox TextChanged() handler:

private void tb_TextChanged(object sender, EventArgs e)


TextBox tb;

tb = (TextBox)sender;

//Prove we can get the name of the TextBox that had its text changed

MessageBox.Show(tb.Name + " TextChanged");


private void b_Click(object sender, EventArgs e)


Button b;

b = (Button)sender;

//Prove we can get the name of the Button that had its click event called

MessageBox.Show(b.Name + " Click");


private void bGetValues_Click(object sender, EventArgs e)


//Getting the events to fire is all well and good, but how do we collect

//the data from the form when Save is clicked? I am presuming that there

//are dozens of dynamically created controls on this form. Well, this is


TextBox tb;

//Find the TextBox Control named "tbTest"

tb = (TextBox)this.Controls.Find("tbTest", true)[0];

//Prove we can get the Text that was entered in that textbox
