help me to add dynamically textboxe to a form when clicking button and reterive data in that text box wen cliking another button

The code to do that will be something like this.

The skeleton event handlers should of course be added via the Visual Studio Designer - they won't be 'wired up' otherwise:

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

}

private void button1_Click(object sender, EventArgs e)

{

TextBox tb = new TextBox();

tb.Name = "DynamicTextBox";

tb.Location = new System.Drawing.Point(90, 40); // or whatever

tb.Size = new System.Drawing.Size(100, 20);

this.Controls.Add(tb);

button1.Enabled = false;

}

private void button2_Click(object sender, EventArgs e)

{

TextBox tb = (TextBox)this.Controls["DynamicTextBox"];

if (tb.Text.Length == 0)

{

MessageBox.Show("Nothing has yet been written to the textbox");

}

else

{

MessageBox.Show(String.Format("The textbox contains '{0}'", tb.Text));

}
