Hello Samir ,
The textarea doesn't have a maximum length property, but you can achieve
what you want through a simple vbscript code.
First you need to create a VBscript method that would check on the
maxlength and disallow any additions if the maxlength is passed.Here is a
sample:

<script language="vbscript">

dim maxlength
maxlength =5
sub EnsureMaxLength()
if (len(document.Form1.mytextarea.innerText) >=(maxlength+1))then
document.Form1.mytextarea.innerText =
left(document.Form1.mytextarea.innerText,maxlength)
end if
end sub

</script>

You need also to call this method in the onpropertychange event of the
textarea

Samir, this post by Peter Blum shows how to use a
RegularExpressionValidator to ensure that a form field's length is
within a certain bounds:

I have created a custom validator control that you can use to ensure
that a TextBox (even a multi-lined one) is less than a certain value.
