title: How to select checkbox and display values in textboxes and when checkbox not selected dont show value
body: <p>I have created a <code>Checkboxlist</code> , <code>Button</code> and two <code>TextBoxes</code>.</p>
  
  <p>When selecting the first value in the <code>checkboxes</code> and press <code>button</code> I want to display it in one of the <code>textboxes</code> and when I uncheck the <code>checkboxes</code> I want the value to disappear from the <code>textboxes</code>.</p>
  
  <pre><code>if (CheckBoxPersonalInfo.Items[0].Selected)
              {
                  LabelFirstName.Text = CheckBoxPersonalInfo.Items[0].Text;
              }
              else
              {
                  LabelFirstName.Text = "";
              }
  
              if (CheckBoxPersonalInfo.Items[1].Selected)
              {
                  LabelLastName.Text = CheckBoxPersonalInfo.Items[1].Text;
              }
              else
              {
                  LabelLastName.Text = "";
