Great component.

thanks.

The more I see of this grid, the more it impresses me. Great stuff.

Lots of good info that I was needing in this video, so thanks for posting it. But it stops short of a topic of interest when considering using the Data Grid + DB adapter with an actual database server: How do the two data loading modes affect the ability to push edits to the server? And with a server come multiple users, so what do we need to know about how the two modes deal with conflicting edits? (And/or is there a locking mechanism to avoid more than one user editing the same record?). Thanks.

Hi I want to create a json string for grids Columns (A Collection) but get AV errors , whats going on?

@tmssoftwareTV: What are the prospects for getting this control properly documented and demoed? As it currently stands, TTMSFNCTreeView has 111 events, of which only 91 are listed in the help docs. And of the ones that are listed, 100% of them have "explanations" that simply repeat pointlessly what the event name already tells us, like: "OnAfterDrawNode: Event called after a node is drawn.", and no other clue regarding typical functionality one might implement with each event. So while one of the flagship features of this component is that it can deal quickly with a large number of nodes by operating "virtually", which completely relies on Events, yet 100% of the Events are undocumented. The help doesn't even show the arguments of the event, from which we might glean some idea of its purpose or intended use. In order to make any progress at all I had to create a project in which I added event handlers for all 111 events, just so I could get a list of all the event handler signatures in which the arguments are displayed. But that still leaves many points unanswered. So far I have also failed to find a realistic demo of how to use this component in virtual mode where it obtains data from a separate data structure. That's an obstacle to using this control, and also a missed opportunity to show how its operation parallels that of Jam/Lischke Virtual TreeView, which would allow users of that control to quickly adapt to this one.

An important question is how to associate data with each node. Unlike in Collection mode, in Virtual mode the treeview fires an event to get data for each for each node, for example, to compose text for the node (and other cells in the row if present). Normally the needed data comes from some other data structure, so on each treeview node you would want to store a pointer or id of some kind to link it to the data element in the other data structure. Jam/Lischke Virtual Treeview has just such a "user values" section in its Node record. However I don't see such a facility in FNC TreeView's documentation. The demo in this video relies on the over-simplification of just satisfying GetNodeText with trivial data available within the TTMSFNCTreeViewVirtualNode, rather than showing how to link to some "external" data structure. 12:12 suggests that maybe Node.Row could be used as a key into a list structure connecting to the external data structure. However, I'm skeptical because those Row numbers will (or should!) change when nodes are expanded and the number of children then quantified, or if nodes are inserted for any other reason. So it would be good if there was an example of how to use the FNC TreeView in virtual mode with the external data that is the main rationale for virtual mode.

It seems there may be in an issue: "because you specify the number of nodes on every level and basically right from the start before the values are being supplied for these numbers". But if that's the case, then the control wouldn't be able to defer determining the number of children until the time the user clicks on the "expand" icon for that row. Virtual Treeview handles this by allowing to initialize each node with ivsHasChildren, which causes an expand icon to appear for that node, and does not call for the number of children (OnInitChildren event) until the user actually clicks on that expand icon. This is important to enable scenarios with very large deep trees, or trees with cycles in their graph; if a tree control insists on determining the number of children of every node to unlimited depth, then the former scenario would take a long time to prepare, and the latter would loop indefinitely and crash. So I would very much like to know how FNC TreeView handles this.

Question: How does TMS FNC Data Grid deal with the issues that previously DBAdvGrid addressed with the PageMode setting? That is, the choice between loading from the database server only the records required for display (Paging), versus loading all the records (possibly time consuming) and thus facilitating much faster subsequent scrolling, and more importantly, facilitating sorting and filtering. Also the first of these modes I believe maintains a cursor on the server, which enables immediate writing of edited data, whereas the non-paging mode disconnects from the server after loading all the records, and some kind of additional steps are needed to write the data to the server. Anyhow, what approach(es) does FNC Data Grid take to this tradeoff? I'm not seeing this discussed in the documentation. Thanks.

Super!

Is this also possible to create bootstrap DB grids?

Thanks. excellent.

Very original thumbnail, your face + pointing. The #1 sign of mediocrity on KZbin. Don’t consider for a second how looking like EVERYONE else makes you an ignorant lemming, not a marketing genius 😂

thanks

One more fullstack example like music library demo will be nice and useful.

thanks

doing it this way (Lazarus v3.6 and TMS web core academics version). When trying to rebuild, it stops and marks line 612 "property Padding" (Error: no property found to override/Error: This kind of property cannot be published/Error: Syntax error, "READ" expected but ";" found). Any ideas?

combination of grid filter with pagination is chalenging. filter in current page or filter in whole table and return new page?

How about adding side menu to bootstrap application. Any hints about css adjustments?

This looks very cool! Thanks for the overview. If you have a lot of stuff for each "page", would it make sense to use a PageControl with the tabs hidden and use this to switch between the pages, rather than the panels?

Is the TMS component totally free?

7:40 is not working for me: There is no overloaded version of "Add" that can be called with these arguments. And there is no update available. Is this a new feature?

Good work! You should add an option to enable column-based searching. For example, when a user clicks on any column in the grid, it transforms into a TEdit field where the user can type, and the grid automatically filters its data based on that column.

is it has column summary like sum of a column, or avg of a column etc.

These 10 minute clips are perfect TMS snacks for me. I also like the 7 course dinners that Holger Flick serves very much but snacks I cannot resist

It's looking good so far. However, the make or break for me is how well it handles a connection to a data set. I also need to see the full list of in-grid editors, and whether they can be dynamically determined for each cell (not just choosing for a whole column)

Just what i need

That's Great!

Is this a web or desktop application?

I found a bug in the ObjectToJsonString, if your Date is in a record type it will become a normal double, if it's in a class it will display correctly with the zulu time and format. It does convert back to your object either way though but will confuse people using your JSON.

Why are all sample programs so ugly, making it seem that there is no interest in learning, even for "hello, world!" it should be more aesthetically pleasing

Thankyou for the info., Can you tell me what the cost of the software please?. I wish to build an alarm system using Delphi. System, alarm box with multi sensor inputs on ic2 bus. Alarms sent to server across a 4g modem. Server is Linux apache for security. Alarms land on server which reports to a dash board on my laptop with neon aero icons glowing red and green subject to on site sensor status. Alarm also sends alarm outcome to android mobile alarm icon tiles neon aero green, red status. I'm a newbie and just a simple electrician. I hope you can help direct me to a simple interface for programming my system Thanks Andrew New Zealand

I did my exams in Pascal Delphi in 2001. Never went back to Delphi. Why? Because there was no programming job for Delphi. To bad. Great language

Random comment in order to support Delphi and TMS Software

Non-visual components: Does this also apply to the TMS TAESEncryption component? Can the TAESEncryption component be run in the WEB Core environment? Can I send an HTTP message to a WEB Core page, have the TAESEncryption component process that message, and have the WEB Core page send back an answer to the client? If so, can you show me a working example?

Why is SmartSetup not installed along with the Dashboard application?

Is the installer bug with MSBuild when compiling the TMS packages (the command line is too long) already fixed? Why not let the user decide whether to use MSBuild or the IDE compiler? Installing packages with the IDE compiler has worked without problems for many years with other package installers. That bug prevented me from renewing my TMS AllAccess license.

Can we edit the components that are added.

Amazing use of chatGPT Bruno. Looking forward to give it a try !

That feature is really not working for me. I copied the template files to the project folder, as you showed in the video, but nothing happened. My project is divided into many folders, one for each functionality. I've also tried copying the template files into each folder of the project, which seems grotesque. And really, nothing happened. Nothing.

Nice.

The next version of tms web core seems to be very good

how to make it as a EXE?

Great products... Thanks to TMS

Wow, suddenly I look forward to building the web part of my project! :)

Awesome!

I love these 10 minute challenges!

Great job Pal.

It would be a good idea to have timestamps on it. Some of us are drive by viewers who need to get to the interesting bits right away, then make the time to watch the whole webinar later.

Another wonderful development from the Amazing TMS Software team. Thank you Pieter, Bruno, and colleagues. Back to school!
