I've started using SlickGrid and have to implement a kind of functionality where I need to show sub-row inside a parent row of SlickGrid.
Here's the scenario
Here's Asia, Europe is having sub categories in Services Column and these service columns are expandable/collapsible
I'm trying to customize this for first column.
Is any other link/source available to refer to accomplish the feature.
Are you aware of the grouping/aggregates example ?
http://mleibman.github.io/SlickGrid/examples/example-grouping
This offers very similar behaviour, but the exact 'cell-merging' behaviour you show is not currently available in SlickGrid. Slickgrid tends to use tree structures rather than a flat structure. That said, it may not be too hard to hack up, but it seems everyone wants a different visual layout and it becomes very hard to support them all.
If you don't need editing or scrolling, I'd suggest this would work best as an HTML table, or even a PDF.

Apologies if this is a repeated question about ui-grid but I could do with being clear on the options for my particular use case. Other similar questions don't conclusively answer my problem.
We are attempting to use ui-grid in a fairly unusual web application where the number of tables on the page is effectively limitless. They get added the more activity the user does. Not ideal but that is what is required.
When using ui-grid, even with a fairly small simple table, it is adding around 1000 watches for each table. And the digest cycle increases significantly with each table being added too. This leads to poor performance when the number of tables increases, as you might expect.
My question is then, is there anything that can be done with ui-grid to reduce these number of watches? i.e. without delving in to the source code to make changes. We are passing our data in to the ui-grid directive using one-time binding notation, but that makes no difference. From looking at other similar questions, it would seem to me that there is nothing else that can be done, which might well imply that ui-grid is not suitable for us.
Alternatively, is there a way within AngularJs to prevent two way binding within a directive? I'm not aware of such a method, but perhaps someone knows a trick to make this happen?!
Finally, can anyone suggest an alternative grid that would be a better fit for our use case? We are trialling ui-grid due to the functionality it provides, such as column selection, cell formatting, ordering, filtering and so on. Are there better performing AngularJS or other JS grids out there that would cover this functionality? Preferably free to use? Others we've considered checking out are Kendo UI, jqxGrid, ag-grid (though perhaps this needs to be paid for).
Any help is massively appreciated.
My company has run into similar issues though not with ui-grid specifically. You've probably already considered this but the fix for us was horizontal and vertical paging. I don't know much about your use case, but we realized that horizontal and vertical scrolling with a huge grid had the same issues you are running into, but it wasn't really any more functional for the user to use a scroll bar than to use page controls to move between blocks of the grid. At most 500 cells would fit on a single screen at a time and it was very easy to lose your place trying to use a scroll bar.
By doing this we're able to use 1 way bindings (probably with bind-once but I would have to dig into the code to be sure). Even with two way binding the same technique should work for you too if it works with your use case.
if you us ag-Grid, there will be no watches. ag-Grid doesn't use Angular at it's core, so doesn't have watches internally.
ag-Grid has two versions, free and enterprise. if you don't need the enterprise features, then use the free versions.
I am trying to create grid with advanced features(filter, re-sizable, scrolling, fixed header, row formatting, cell formatting) using angular js. I have read the following grids documentation.
ng-grid
ng-table
smart-table
And, ng-grid has many features and perfect for our requirements. but I want the following 2 options also. is it possible to achieve from ng-grid?
Formatting
We have number of columns in my grid (approx 40). Most of the column data need to be formatted in cell. for eg: Adding link, change date format, Reducing length of the content with tooltip..etc., Here, I can not do this stuff inside views. But this one is handled perfectly in ng-table.
If I can not do this in view, then my javascript (using callbacks) code is going to be increased. I don't want this way because angular perfectly do dynamic views.
Also, I want Header formatting, filter formatting, row formatting should be done inside views.
Responsive using Bootstrap
Our application should work in all devices. but ng-grid not working as responsive if I view my application in tablet devices.
I'm working on the following grid angular grid - has the features you mention. Similar to ui-grid in it's basic interface, but approaches things differently, including how the grid is customized. You can add css styling at the column and cell level, as well as providing your own custom cell renderers for complete control.
Asik,
The project Angular-UI renamed the ng-Grid to UI-Grid and the website changed to http://ui-grid.info.
Now it's pure AngularJS, without jQuery, use Bootstrap 3 LESS and it's full features that fill your requirements.
Take a look in the page of Tutorials to check the power of features.
I've found a few plugins that does this, but they either have more than what I want which gets in the way and none of them do exactly what I need. Some I simply can't get to work with firebug showing syntax errors in the style sheets even though it seems perfectly fine.
I want something very simple in terms of visuals. Basically I want this:
http://demos.devexpress.com/aspxgridviewdemos/groupingsorting/grouping.aspx
If you look at the link then you will see that you can re-order the columns by dragging the headers, but you can also drag the headers out to where it says "Drag a column header here to group by that column"
I just want a plain way to do this in javascript/jquery with some callback so I can store the column order in an array after you change the order. The data changes I can handle, it's the dragging of the columns and then changing the order or removing the column and adding it to the Group space above that I have issues with.
We actually do you devexpress controls, but for what we're doing it's to slow with all the callbacks their grid needs to do when you do anything on the thing. So we're in the process of creating our own ajax grid that does what we want and how we want it with only what we need.
I hope this makes sense and that someone can help.
I have recently looked at implementing something similar, so while I can't post a code example, I'd recommend looking at jQuery UI Draggable to let you drag the columns to where you want them.
Make the table column order configurable through javascript first. Then make the column headings draggable and based on the new position redraw the table based on the new column layout.
This approach should be faster as you can optimise for your use cases.
Cocoa Touch's UITableView allows a user to scroll through large numbers of data rows with good performance because it recycles table rows. Rather than create a GUI element for every single data row, a limited number of table rows is created, and simply updated with the relevant data as the user scrolls, giving the illusion of navigating up and down a very large number of table rows.
Has anyone seen this done in javascript? Is there a plugin available anywhere that will do this for me?
infinity.js works well. It will dynamically load 'pages' behind the scenes giving you the appearance that the list has been fully loaded.
More information can be found on their Github page - https://github.com/airbnb/infinity
Additionally, I've forked the project updating it to work with Zepto. I also set it up to use any scrollable div (set up with overflow: scoll) with the class 'scrollable' - https://github.com/elliotcw/infinity
I should add that I made these changes as this is great for large lists on mobile devices, which slow down when you have to many complex elements on the page.
I was looking for this as well, and infinityjs [1] doesn't seem to quite mimic the same interface as UITableView. And it was a problem for my scenario that infinityjs required that the element containing the list items already be added to the DOM.
MegaList [2] came closest to what I wanted. Andrew (author) has done a great job of designing it for mobile first, with touch support etc. One caveat for me was that it appears to assume a strict selection list model and does a little bit more than I'd like a list component to do (e.g. binding to resize events and trying to handle that automatically).
So I started writing a barebones list component, also modeled after the iOS UITableView. It's a work in progress and I'm putting in just what I need. Sources are here https://github.com/shyam-habarakada/js-virtual-list-view. I'm putting in just what I need as I go, and contributors are needed :-)

Actually the algorithm is not difficult at all. If you know javascript you should be able to write this. The algorithm only needs the height of a cell and the height of the table.
I only know these two:
Apple's Dashcode javascript Framework has an implementation of a Table. You could take a look and see if that is what you need.
Or Cappuccino Framework which is basically Objective-J but behind the scenes is Javascript.
Clusterize.js does exactly that.
It's small and works with any tag (table, lists, divs)
I want to add paginated table to a page. It should be 2 rows by 4 columns. Each cell contains a thumbnail image and some small links.
We're using YUI elsewhere on the project, so I'd like to use the Datatable. All the examples I see are geared around tabular data (understandable), but my hunch is that I can rewrite the HTML of each cell using Javascript. I don't see the callback function I should hook to rewrite the cells.
Possible? Or am I trying to hammer in a nail with a screwdriver? If there's a simpler way to do this with YUI I'd love to hear about it.
thanks!
jcooper,
To paginate a simple grid of image/text elements, I'd almost prefer to see you use the Paginator without using DataTable. DataTable is a powerful component, but it's working hard to be a lot of things you don't need.
Carousel (http://developer.yahoo.com/yui/carousel/ ), on the other hand, seems like it's trying to be just what you want. http://developer.yahoo.com/yui/examples/carousel/csl_imagentext.html , for example, might be a good place to start.
If that's not quite what you want, you could definitely do this with DataTable. Just create the markup snippets you want to use for each cell, store them in an array, and follow the directions for using an array datasource and pagination.
Regards,
Eric
