Frank,
Downloading and installing the file Gene.zip was easy done succesfull.
The form: I am not able to enter a value in column #Weird if I have entered
8 in the column text. Is that how it is supposed to work?
I came up with some simple rules to test validation. They are
arbitrary, but they are also simple. (No sense having them be
complicated for a proof of concept.)
Regarding weirdnr:
1) weirdnr is supposed to be divisible by 3.
2) It is also supposed to have the same even-oddness as the first
character of thetext.
Example 1: With thetext of "An example", "A" has a value of 65 which
is odd, so weirdnr must be odd. Since it must also be divisible by
3, it must be one of {3, 9, 15, ...} or the negative of one of them.
Example 2: With thetext of "Brilliant or bad example", "B" has a
value of 66 which is even, so weirdnr must be even. Since it must
also be divisible by 3, it must be one of {0, 6, 12, 18, ...} or the
negative of one of them.
The above assumes Frank implemented correctly what I asked for,
and for that matter, that I wrote what I intended. I have just
gotten home from work -- I am working full-time outside of IT -- and
have not looked at his code yet.
I might not get to look at it in detail for a few days. But I
will. This is the first potential grid example that works for my
value of "works". If I have been overlooking something, I want to
know about it.
Mind you, I am going to try to break it, too. I want something
solid and to know that I have something solid.

I came close, but it required a lot of kludges and an innocent change in one place could blow it up. Build a set of controls, save them as class, add that class to the Column, change Column.CurrentControl to point to that class, set Column.Sparse to .F. and presto, you can do any complicated setup and stil have the benefits of VFP's native gridspeed.

RE: AW: Custom Scrollbar
Gene, I am sure you have tried all of the following, but thought I might check regarding the record validation thing. Are you using data from a table that is part of a database? If so, do you have both field and row level validations specified in the dbc? Are you using buffering and CursorGetProp() and related functions/methods to check for field/row level changes? If yes to all above, just ignore this message.. If no to any of the above, that might be part of the problems you are having with the validations.

Gene, back in April last year you were asking if anyone could write code to your specification regarding the grid problems you were having. I don't recall ever seeing your specification, maybe if you posted it someone might be able to do the code for you.

While it can definitely be fun to roll your own, I would also investigate Craig Boyd's gridextras class. It's got a ton of useful features baked in such as column sorting, export, filtering, quick reporting and so on. You basically add an instance to your form, set a few properties and call its setup method when the form instantiates. <http://www.sweetpotatosoftware.com/blog/index.php/2008/11/25/visual-foxpro-grid-enhancements/> -- rk -Original Message- From: ProfoxTech On Behalf Of Gene Wirchenko Sent: Monday, January 7, 2019 10:35 PM To: profoxt...@leafe.com Subject: RE: AW: Custom Scrollbar At 14:47 2019-01-07, "Darren" wrote: >Been watching this thread and decided to pipe in >- I have to observe that I have done some pretty tricky stuff with the >VFP grid.

Re: AW: Custom Scrollbar
Hi Gene: I think that I've found what you need. You need to use the Valid event of the grid in combination with the valid of the controls. Please, read this chapter about grids of the book 1001 things you wanted to know about VFP.

Neither do I, but I have seen this opinion posted many times over the years. I do not understand it myself, but there it is. Not sure about the complexity of what you need to do, but if you used FoxPro before VFP, you could remember that before the grid component was the BROWSE command with many parameters that allowed many validations and options for row/column, and that many validations and options where made exactly for that purpose, for data entry. Most of them have no sense for other purpose than data entry. Yes, but I had a period of time where I was not using xBASE. That was about when the fancy browses had their day. I have looked at BROWSE, and it does not have quite what I want. One of my first programming challenges was to do a component exactly as you need it to (I'm talking about dBase III+ era), and could do it, but the problem was that performed horribly, too slow to navigate records and columns. I think that you could face the same problem. Do not forget that you have to control each and every aspect of the component, as: - Scrolling left/right controlling start and end columns I have this scrolling already working in a concept case. It was fairly easy. I grant that this may change when I add more feature. I do not think so though. - Scrolling top/bottom controlling start and end rows - Controlling the data you load/unload, because you can't load a millon records in memory, and this forces you to control dinamically the loading of a new bunch of records in the direction you are navigating, and unloading records from the other side - Yup! It is going to be fun, but I have some ideas. I am concerned with how the scrollbar works, but I may just come up with my own version that bypasses the issues. Controlling every key for navigation and other needed purposes - Controlling the visualization of each aspect of your info (think on Autosizing columns, pre-programmed sizes, combination of both, assuring that you show columns correctly and fluently ,etc) I do not plan to have every feature that Grid has, at least for the start. I tried to get Grid working when allowing column order to change, and it was horrible. - More things you may ancounter Quite possibly. What I have encountered is trouble with row-level validation. Without that, Grid is NOT what I want. Obviously I'm thinking in a component that can be used for any table, and not just for one special table, because the programming effort to do this type of component is too high to do it for just one table. Don't know if you already said this because I didn't follow the entire thread, but: What type of validation do you need, and what is the problem you are facing that can't be handled with the grid? I can not get proper row-level validation working consistently. I have tried and tried and tried. I keep finding cases where it breaks. I deal with a case, and something else breaks. It is very frustrating. I had quite a lot of trouble to get my test case to work. I had to experiment with events and methods, but once I got it, it worked and did so consistently. And more importantly: Is really a grid what you need? why can't you use an input form with navigation keys that scrolls data in background? Because some of the work that needs to be done needs multiple rows visible at once.
