Getting text values of WinForm Controls

Hi,
I am working on a Windows Forms project. In that I have a form that needs to be dynamically populated controls by looping. At design time I kept one control for each controls(Text Box and Combobox controls) for those I would be generating dynamically. I am taking the name given to the static controls to the dynamically generated controls(like TextName1, TextName2). I could not be able to figure out those dynamic control names while saving? I aken those cOntrols on a panel control. Have any solution for this?

When adding controls dynamically you need to associate an event handler with whatever event or events you need to handle for the dynamically added control. For example, if you want to dynamically add a collection of buttons to a form, you will want to associate an event handler with each of those buttons. In the example below, I am adding some buttons to a form and, as I add them, I am associating a generic event handler (ButtonClicks) with each button. The button is then positioned and added to the form's control collection. In the ButtonClicks event handler, I am casting the sender to be a button control and I am then getting the name value from the button to display which button was clicked in a message box.

public Form1()
{
InitializeComponent();

     for (int i = 0; i < 10; i++)
     {
          Button b = new Button();
          b.Text = "Button " + i;
          b.Name = "Button" + i;
          b.Click += new EventHandler(ButtonClicks);
          b.Top = i * 30;
          b.Left = 10;
          this.Controls.Add(b);
     }
}

public void ButtonClicks(object sender, EventArgs e)
{
MessageBox.Show("You clicked on " + ((Button)(sender)).Name.ToString());
}
