Question

Is there any ways to make a text box visible when user click a button? What I meant here is, user will only see the text box when button is clicked. Thanks in advance for help me. Have a good ones.

Answer 1

Make the button Visible on button Click event.

Double click on the button to add a Click event handler.

Your code should look as follows:

private void btnShow_Click(object sender, EventArgs e)
{
    txtBox.Visible = true;
}

If you don’t want the whole page to refresh on doing this, you may want to wrap these controls inside an updatePanel
