Question

I have a textarea which is dynamicly changed in c# by doing this:

TextBox1.Text=(String)Application["chat"]; 

When the text is to big for the textarea, I would like the scroll to always be on the bottom. I have tried to do this in JS(jquery) with the change event.

$("#TextBox1").change(function () {
    alert("alert");
    // $('#TextBox1').scrollTop($('#TextBox1')[0].scrollHeight);
});

This is the code I use in Javascript. The problem is that the event does not occur, even if the text in the textarea is changed, which I have proven by debuging it with the alert which does not execute.

Answer 1

var textarea = document.getElementById('textarea_id');
textarea.scrollTop = textarea.scrollHeight;
