title: Clear data after submit button from text box and labels
body: <p>i have a web form that asks for the mobile number and id, if the id or mobile are incorrect. the web page will display an error label, after this error label if i entered a correct information this form will be not visible anymore and a new div will be visible with another display. so here the problem is when the customer enters the new info after a wrong info, if he clicks back the label is still appearing and text box 2, i have set these elements to:</p>
  
  <pre><code>lblfailedresponce.Text = ""  // 1rsst text box 
  txtMobilePhone.Text = ""     //2nd text box
  TransactionID.Text = ""      // label 
  </code></pre>
  
  <p>but it didn't work and they still appear. so what is the code in the submit button that i have to do to clear the cache or the fields from the invisible form? </p>
