The next example uses a test.aspx page named SetAndGetTextBox.aspx which has two asp:Label controls and one asp:TextBox control. In the code behind the local string variable value is use to read in it the system date and time by using:

value = DateTime.Now.ToString();

The rows in bold show how value is used to set the TextBox and how the TextBox is used to set the Label.
