Restrict number of rows in Text area

Hi,

This is possible using a script 

Add a data label to your view/form then check literal property and uncheck PreventXSS

Add the following script as an expression on the data label:

<script>
$('#TextAreaID').on('keydown keypress keyup',function(e){ 
if(e.keyCode == 8 || e.keyCode == 46){ 
return true; 
} 
var maxRowCount = $(this).attr("rows"); 
var lineCount = $(this).val().split('
').length; 
if(e.keyCode == 13){ 
if(lineCount == maxRowCount){ 
return false; 
} } 
var jsElement = $(this)[0]; 
if(jsElement.clientHeight < jsElement.scrollHeight){ 
var text = $(this).val(); text= text.slice(0, -1); $(this).val(text); 
return false; 
} });
</script>
