Guest Posted February 25, 2011 Posted February 25, 2011 Message from: "Stefano Monterisi" Hi, your product is fantastic for Delphi programmer. But, for as professional use I need some features that can boost productivity and freedom on development. Web users must use it as a normal application without paginate grids or scroll only a limited dataset. I need a grid that load data on demand, without paging and only with scrollbars; It must be ordered, searched and filtered (as Devexpress does) so user can use it as a desktop application. The same also for Dblookups and other data-relative information. What are the limit of sytem? Can one web application be used from 500 concurrent users at once (with adeguate hardware and well planned application)? Or the product is voted for a hobby market? I am very very interest in the product but I need to understand what are planned intentions for this product. Naturally I can pay for a professional product :-) Thanks, Stefano Monterisi . Quote

As long as system resources allow 500 simulatenous sessions should be no problem. As framework advances more advanced features such as pooling datamoulde will be implemented. The server core has went through various stress tests many times. Further stress tests will be performed in future. Regards, Farshad Mohajeri . Quote

What mechanisms are used to demand the data and > how much data is inserted at each demand? The real problem in web application vs. desktop application is how we can manage big data tables. If I have to search a record (DblookupCombobox) in a table with 100000 records on server, have the capability (into browser) to load in the list records dinamically (only the number of records that fill the list) or I must wait that client browser must load all 100000 records? It's clear that mine is an example.....the way how manage data on the server side is a programmer problem, but if I have a ready dataset with 30000 records to scroll, there is a way for scroll it dinamically in the browser? But I don't like paging, I need a perfect desktop simulation: user must scroll grid with the scrollbars on cursor keys....and data must be fetched dinamically from dataset (with sort, filter, and other features). The best way is how Devexpress do with its "server mode" grid in their aspx components (and Delphi for the end of year), but this is a complex problem that involve also data management. Your product is very very interesting and productive, but the difference is played on data fetching, validation ed data input, for professional use.

Guest Posted March 1, 2011 Author Posted March 1, 2011 Message from: "Stefano Monterisi" Hi, maybe that what I am looking for is already implemented; If yes, please tell me. I have only see demos and I don't have still used it :-) There is a price planning for the product? Thanks, Stefano Monterisi . Quote

Paging seems to be the only way. All modern web apps use paging for it. I'm not aware of any alternative technology which can append data as you navigate in DBGrid. Ext JS grid can't load data it this way. > The best way is how Devexpress do with its "server mode" grid in their > aspx components (and Delphi for the end of year), but this is a complex > problem that involve also data management. In TClientDataSet we have FetchOnDemand option. It works excatly as you expect here. Problem here is that how this is going to be implemented on the web side. IMO, showing thousands of records in a Grid is meaningless. Even in paged mode users can't do anything meaningful with this huge amount of rows. I personally limit the maxium rows to 1000 and ask users to filter data until they find what they need. > Your product is very very interesting and productive, but the difference > is played on data fetching, validation ed data input, for professional > use. > Good job, Thank you. .

TI.ME Posted April 17, 2019 Posted April 17, 2019 Would you like to know more ... You can work with Fetch on Demand? Thanks.. Att.: Gustavo Déo.. Quote
Hayri ASLAN Posted April 17, 2019 Posted April 17, 2019 It is our in backlog. We will implement this feature. Quote
adragan Posted April 19, 2019 Posted April 19, 2019 Browsing through 10000 records is meaningless. Using a significant result set from a query is something one needs. If it's about testing the performance of the framework, I can understand, but for a real world application it's a waste of time and resources. Quote

Hayri ASLAN Posted May 15, 2019 Posted May 15, 2019 It is not in the next 2 sprint. Most likely after that. Quote

It will help a lot in the speed of opening of screens ode there medium and large volume of data ... Any prediction? 1 Quote
