OK, I will check if it can be done with the DataGridview control which is the tooltable control type, I'm not sure if it can be done and if it can how, I mean I've not used this type of control too often yet and it is a pretty compex control with lots of properties and events etc., so I will have to check it out to see if and how is it possible.
The Wear Time and Wear Limit and Tool life are things which are not functions of the UCCNC at the moment (yet), so if we add these into the tooltable now then people may start to think that these are somehow functioned in the software and this could give a false impression to the user. And I'm sure this would lead to receiving lots of email questions from customers and even to people getting angry because these things being there made them think the software actually makes calcuations of these things while it is not. So, for this reason we did not add these yet.
I saw that your example tooltable has these properties too and the above described is the reason why these were not added now.
Empty values need to be NULL as teh zero effects sorting
Empty values are actually null in the table. I have checked this a few days ago, because this exact thing caused some issues when we developed the tooltable, so I'm sure they are null.
What exactly do you mean by "sorting"? How should it sort different then how it is sorting now? Please describe to let me understand and see if we can do it that way.
