Would like to show column grouping for a few columns in the RaddGantt.

e.g.

• Planned Start and Planned End to be grouped under Planned
• Actual Start and Actual End to be grouped under Actual
• Financial Detail columns to be grouped under Task Financials

Also, would like to add to the query, how can I have the Gantt chart with the dates shown vertically as in the image attached. I don't want the Week or Month name coming in the grouping. Just dates in the timeline view.

Reference

When endless scrolling and grouping is enabled on the KendoUI grid, collapsing large groups causes the grid to load ALL the hidden detail rows into the DOM.

This takes a very long time for the grid to do, as well it violates the whole point of a paging system. (ie I only want you to load X records at a time). Afterwards the performance of entire website (including the grid) will be very poor since potentially thousands of rows have been loaded into the grid and then immediately hidden. Additionally, these rows do not add any value to the user, since they are all hidden anyways.

When a category is collapsed, the grid should NOT add any new rows for that category to the DOM.

I have included a sample that demonstrates the performance issues.

It would be better if we can customize circle(depend on type of entity we can paint it with different borders).

Instead of date show something else. It is not possible with api now, but I think it is easy to make everything replaceable with custom templates.

Concerning Cross Site Scripting (XSS), from the client-side perspective, data coming from any server cannot be trusted, even when it's one of your own servers (which may have been hacked).
While it is true that you need XSS protection on your server, it's certainly not a luxury to have additional protection on the client-side.

The kendo.template() function for example can be extended to filter out any unwanted <script> tags. The following code would do it:

<code>
var kendoTemplate = kendo.template;
kendo.template = function () {
    var templateFunction = kendoTemplate.apply(kendoTemplate, arguments);
    return function () {
        var htmlWithoutScripts = $.parseHTML(templateFunction.apply(templateFunction, arguments));
        return $("<div></div>").html(htmlWithoutScripts).html();
    }
};
</code>

The jQuery.parseHTML() function will strip any <script> tags...
I'm not sure what the impact is for performance when there are too many repeated template calls on the same screen, but for normal use the overhead should be minimal.
Maybe this code can be run only for the HTML expressions in the template (#= expression#).

Could this kind of XSS protection be added to Kendo UI by default? Or at least be available as an option?

I have a list of entities with a large set of fields, but I don't want to load and display all of them in the grid. Entities have also a couple of complex properties which are displayed via checkbox lists.

Though, I want them to appear when editing a single entity.

For now, I'm using custom "create" and "edit" pages, but it would be great to have an "url" option for popup editing. This url would return some html (MVC partial view in my case) which would be rendered in the popup window.

Confirmation messaage required to before delete record from a data grid. It should be looks like 'Are you sure you want to delete the record

Having custom sorting on the grid is really handy. 
But with its current implementation, we are not capable of setting this sorting logic on load.

I opened a support ticket for this issue (see below), and now I'm considering extending this behaviour myself, if I can manage the time that is.

However, it would be so much better if this was supported out of the box

Currently, the Kendo ListBox has methods to return -- the DOM Elements using items(); the Selected DOM Elements using select(); ALL of the Data Items using .dataItems() and a SINGLE dataItem using dataItem(selector).

An additional method that would be extremely useful for this control, would be to return the SELECTED DATA ITEMS perhaps using a method  selectedDataItems().

Here is a JavaScript function that can be used as a template for providing the functionality (of course, it needs additional error checking):

    function getSelectedItems(lstName) {
         var selectedItems = [];
         //var lstItems = $(lstName).data("kendoListBox").items();
         var lstItems = $(lstName).data("kendoListBox").select();

        $(lstItems).each(function (index) {
            var selected = $(this).hasClass("k-state-selected");
            if (selected) {
                var id = "#" + $(this).attr("id");
                var dataItem = $(lstName).data("kendoListBox").dataItem(id);
                selectedItems.push(dataItem);
            }
        });
        return selectedItems;
    }

In a control such as a ListBox that inherently requires the functionality of "selection" -- then your user community would definitely need a way to not only return the selected DOM elements but also return the selected dataItems.

Hopefully, we see this functionality added to the Kendo ListBox very soon.

I believe a kanban board for managing tasks woudl be a great new control.  I see that you have something like this in TeamPulse already.  In the new control it would be nice to set the number of columns, custom template for an item (but providing a template that resembles sticky pad note would be cool) and allow drag/drop between the columns.  The D&D would need to be customizable so that the programmer could restrict which columns an item can move to & from.  This would be needed in case they did not want to allow the user to move an item to a previous state or may only allow to move forward 1 step.  The reason I put this under bootstrap is because the control should reposition columns below based on screen size.  So it may start as a 4 column board but because of the size of the window it is a 2x2.

I would like to use drag and drop on treeList to reorder rows (with same parent) like on treeView or at least to have same events (drag, dragstart, dragend, drop), where I'll be able to change behaviour.

With this customization it will be possible to use checkboxes or combo boxes and normalize the selection of data. Actually is possible to use only text and date columns.

Add ability to define connection visual template option for the whole connection path. In this way the user can define custom connection types (like 'polyspline' ).

Someting like:

Current when using the HierarchicalDataSource you can only load one level of data at a time. I would like to be able to pre-populate the entire tree (but have the ability to refresh it via remote data, should I so need).

I'm interested in using the Gantt chart for a project scheduling application but I need a lot more customization on the look & feel than is currently available. For instance, being able to eliminate the secondary timescale bar under the primary so that if you're in, say, the month view there is no 'week' slots under it.

It would be great if you would add accessabbility to the spreadsheet as it seems to be the last control without this feature.

Currently the focus gets trapped inside its grid and the user cannot leave the spreadsheet with the TAB key. At least this should be avoided. It would be also better if only the first cell would be focusable and you then could navigate with the arrow keys, as with thousands of cells it is not very comfortable to use the TAB key.

Hi,

For example, if you look at this chart in 10 days zoom view, you will notice they skip the weekends, means, they are not drawing empty data points for weekends. It is normal requirements for candle charts in stock market.
