I am trying to validate my textbox with spacebar, If someone open my page and in text box click on spacebar and click on btn save it should not accept the value and give the error field should not be empty. the code which i use to validate is

if (txbDiag.Text.Trim().Length <= 0)
{
   msgError.Text =  "<b><font Color=red>*" + "fields are mandatory"+"</font>";
   msgError.Focus();
   return false;
}

and on btn click i use

txbDiag.Text.Trim();

but while clicking on btn save page is getting saved.

i used the js

<script type="text/javascript">
   function validate(e) {
    var unicode = e.charCode ? e.charCode : e.keyCode;

    if (unicode == 32) {
        return false;
    }
    else {
        return true;
    }
}
</script>

but this is also not working

I used regular expression and requir field validation that also not causing validation

HOW COULD I VALIDATE MY TEXT BOX FROM SPACEBAR HELP ME????
