How max length for a text field is enforced

[pbo]

When I add a new text field to a table (incident for example) and choose Small (40) or Medium, I may not add more than 40 (100) caracters in this field

But if you choose Large (1000) or X-Large (4000), I may add as many caracters as I want

Is it possible to modify this ?

If its greater than 255 , SN assigns as large data type in the back end.

We use client script to restrict this. below is the script.

var control = g_form.getControl(fieldName);
if (control.value.length > mLength){
g_form.hideErrorBox(fieldName);
g_form.showErrorBox(fieldName, 'You have reached the maximum limit of ' + mLength + ' characters for this field.');
control.value=control.value.substring(0,mLength);
}
else{
g_form.hideErrorBox(fieldName);
}
}
