255 Character Limit on Document Library Text Fields
Had a friend ask “Do you know of a way to increase "description" fields (currently only 255 characters are allowed) in Doc libraries ?”
The answer is that this limit is set in the ows.js script file (not the database). Look for the function
NoteFieldFValidateCore and remove (or change) the following snippet:
if (fld.frm.wBaseType == 1 && field.value && field.value.length > 255)
{
fld.stError = StBuildParam(L_TextFieldMax_Text, fld.stDisplay, 255);
return false;
}
