  open the CRM entity form and on the textbox change() event, write this code

  var length = crmForma.all.yourTextField.DataValue.Length;

  you can also do the same on the onSave() or onLoad() event, depending on your needs.

  you can use this same java script function against particular field and then put this code in Form On Load Event as follows

  for e.g assuming you want to put this check on account name field following example code for the same..

  // function parameters are: field - the string field, count - the field for remaining characters number and max - the maximum number of characters 
  function CountLeft() {
  
  var max =50;
  var field = document.getElementById('name'); 
  var count = 0;
  
  // if the length of the string in the input field is greater than the max value, trim it 
  if (field.value.length > max)
  field.value = field.value.substring(0, max);
  else
  // calculate the remaining characters 
  count.value = max - field.value.length;
  }
  
  //name is accountname field)
  var element = document.getElementById('name'); 
  
  element.attachEvent("onkeyup", CountLeft());
  element.attachEvent("onkeydown", CountLeft());

  Yeah, you need to add new field on the CRM Entity ..let's assume you call it remplace you need to put that on the form besides actual field..on form mark that field as readonly.....

  following is changed code based on this..hope this helps..

  // function parameters are: field - the string field, count - the field for remaining characters number and max - the maximum number of characters
  function CountLeft() {
  
  var max =50;
  var field = document.getElementById('name');

  var countfield = document.getElementById('remplace');

  
  var count = 0;
  
  // if the length of the string in the input field is greater than the max value, trim it
  if (field.value.length > max)
  field.value = field.value.substring(0, max);
  else
  // calculate the remaining characters
  count.value = max - field.value.length;

  countfield.value = count;

  
  }
  
  //name is accountname field)
  var element = document.getElementById('name');
  
  element.attachEvent("onkeyup", CountLeft());
  element.attachEvent("onkeydown", CountLeft());
