I have a field (event_description) that is a textarea -- it is set for row="3"
cols="60" -- I was hoping that the user could only enter up to 3 rows -- but when the description is longer the user can continue to enter data -- I'm using SQL server and the field is varchar (255) so I don't want the user to enter more than 255 characters -- What are my options ?? I though I could limit the textarea with rows and cols but that doesn't seem to be the case -- Any suggestions ?? Thanks jo

Jo,
textarea let you enter unlimited number of character and it cannot be limited as e.g. textbox. The workaround is to use javascript that will cut extra characters. E.g.:
<SCRIPT Language="JavaScript">
document.FormName.FieldName.onkeydown=myfunc;
function myfunc() {
var tmp = 0;
var tmp1 = 0;
tmp = document.FormName.FieldName.value;
tmp1 = tmp.length;
if (tmp1 >= 255)
document.FormName.FieldName.value = document.FormName.FieldName.substr(0, 255);
}
</SCRIPT>
As usual javascript code is to be added to footer section of the form.

there's no textarea limit. one possible solution might be to use javascript to ensure the user enters less than 255 characters. or maybe u can do something with sql to allow more than 255. ( but i have no idea about sql. )

I'm just learn js but I think there is an error in the one statement that Nicole provided ...
was
document.FormName.FieldName.value = document.FormName.FieldName.substr(0, 255);
should be
document.FormName.FieldName.value = document.FormName.FieldName.value.substr(0, 255);
Hope that helps
