before rendering html

<div class="form-group">    @html.labelfor(model => model.catchphrase, htmlattributes: new { @class = "control-label col-lg-2 col-md-2 col-sm-2 col-xs-2" })    <div class="col-lg-10 col-md-10 col-sm-10 col-xs-10">      @html.textareafor(model => model.catchphrase, new { htmlattributes = new { id = "profilecatchphrase", @class = "form-control" } }) @html.validationmessagefor(model => model.catchphrase, "", new { @class = "text-danger" })    </div>  </div>

try this:

$('#catchphrase').on('input', function() {   $(this).outerheight(38).outerheight(this.scrollheight); });
