If you want the date and time to change dynamically - so it will display the current date/time each time the focus enters the textbox - then you need to overlay the previous date/time (if there is one) with the new one.

Try this code:

private void textBox1_Enter(object sender, EventArgs e)
{
string temp = DateTime.Now.ToString("dd/MM/yyyy HH:mm:ss");
if (textBox1.Text == "")
{
textBox1.Text = temp;
}
else
{
textBox1.Text = temp + textBox1.Text.Substring(19);
}
}

Hi Sona.

in your textbox focus event you can check if the textbox already has some data then you dont need to display the textbox with current datetime and you can skip the process, this way the value in your textbox is not overwritten.
