I'm using a dhtmlx-grid and have a problem in the following use case.
I enabled multiple selection and the grid uses smart rendering to load a large set of data.
After the initial load, I select the first row in the grid, and then drag down the scrollbar to the last row and shift-click the last row.
The expected behavior is that all the rows in the grid should be selected, but this isn't the case.
The not-rendered-rows in between are not selected.
Glad if somebody can suggest me some good solution.
Thanks
Unfortunately, only the rendered rows can be selected, so in case of enabled smart rendering mode you cannot implement the described steps. The only solution is to disable the smart rendering mode.

I am working with a big amount of data (1M - 5M), and rows in the grid should be groupable, sortable, and filterable. As ag-grid can populate table with data quickly enough, I use in-memory row model to satisfy requirements.
However, when I click column in order to sort all rows by this column, it takes some time to do this. Moreover, sequential clicking on columns while rows are still being sorted may crash grid as well as browser application.
Are there any ways to prevent user from clicking on columns (disable sorting, show loading overlay, or something like this)?
I am trying to use beforeSortChanged and afterSortChanged events to show overlay or modify DOM elements (to make grid a little bit grey and show loading circle), but it doesn't work properly: beforeSortChanged event handler seems to be stuck for a moment and then only executed.
Ag-grid is used inside Ember framework as a component.
How about using onCellClicked which is an attribute of the columnDefs. Should work in a similar manner to what you are looking for with beforeSortChanged.
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 ?

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.
We have a display issue with Microsoft Dynamics CRM 2011. We have a large customized form, and we show and hide various things based on data on the form (usually the owner and a few other lookup values). The problem we have is that the forms are very ugly. We have two columns, and when we hide something in the left column, it will cause the item adjacent to it in the right column to move over. We would like things to stay in their columns, and flow upward to fill gaps.
Has anyone had experience with this and is this possible? I'm hoping there's a javascript solution to do this.
According to some CRM documentation this is caused by the way the page and DOM elements get loaded, and setting the display to none on the disappearing elements will keep the structure better. However, while trying this, it still loaded the incorrect way, so I tried another solution.
I tacked on the new fields in their own section. Visually it isn't perfect, but it at least forces them to stay on the right side.
I'm currently working with a dojo datagrid that works perfectly well except for one small problem. Due to a large number of fields that must be accounted for, clicking on a column to sort the contents of the grid by the value within that column can be rather time consuming (several seconds). Is there any way to display to my users that the content of the grid is "loading"/"sorting"/etc during this downtime? I've looked around the web but only found loading masks and no sorting masks. As far as I can tell there are no built-in methods for detecting sorting or changes in sorting.
Thanks in advance.
This Post handles the onHeaderCellClick event which would catch the onClick in the header.
Declarative dojox.grid.datagrid's header has onclick event?
Theres a fiddle in the Post, which disrcibes it very well.
You can use it to make a loadingimage visible and hide it again, when sortig ends.

Is there a way to display a component in EditorGridPanel without the need to click on the cell?
The problem I see on this demo is that the checkboxes are not Ext.form.Checkbox components, and not even inherited from it. The checkboxes are simply background images and since I am building a grid that needs ComboBoxes, it will not be simple to apply a similar hack.
Ok, I see what you're after now. Immediately display the combobox on each row upon grid rendering. That might be difficult to achieve, and I suspect it might have a negative effect on the overall performance of the grid (multiple comboboxes to render instead of just one).
In any case, have you looked at the clicksToEdit config option of EditorGridPanel? From ExtJS documentation:
The number of clicks on a cell
required to display the cell's editor
(defaults to 2).
Setting this option to 'auto' means
that mousedown on the selected cell
starts editing that cell.
How about if you tried setting this to 'auto'? That would at least reduce the amount of mouseclicks that the user has to do, before editing starts. Is that what you're really after with this?
(Note that I haven't tried this option myself, so I don't know how well it actually works with Comboboxes.)
