When scrolling data in a grid using the virtualization scrolling option, the query to fetch the next section of data will occur twice. It does not happen for every query, but it does happen all the time regardless of scrolling fast or slow.

Version of Kendo UI Grid: v2016.3.1028

There appear to be a few accessibility issues with the pager control for kendo grid when using a screen reader:

The grid "beforeEdit" event is designed, as per documentation, "for preventing the editing depending on custom logic".

However, this event provides only information about the edited row, not cell, which severely limits what that logic can do.

A related event, "edit", passes information about the container, which is a table cell in incell mode. There is no reason for "beforeEdit" not to do the same - both event are triggered merely several lines apart.

When aggregate sum few child's rows the parent row not calculate only at the bottom of the treelist grid.

First I thought there is a problem in my code, after search I found this post.

I have fixed the data type but as I said the parent not include in the sum group only at the bottom total.

Thanks

Allow to drag the selected range in the range slider.

It would be nice to be able to specify in a datasource filter two fields and an operator for the sake of data reporting. For example, where "completed date" is greater than "promised date" or "Actual cost" is greater than "estimated cost."

This sort of thing can be accomplished by calculated fields; a filter of where "cost overage" is greater than 0. The down side of the calculated field approach is all comparisons need to be pre-defined. 

I want to be able to allow showing tooltip on mouseclick, instead of showing it on hover a slice/point/bar. This should be configurable - what event should trigger a tooltip.

We would like to have this below 2 features included in timeline. It will be really handy.

1. Option to have display more field with date in label of timeline

2. Having multiple event visible for horizontal timeline similar to it comes in vertical timeline kendo ui jquery demo for timeline

Thanks,

Add Link Tab to Image Editor

The idea is to add a link tab within the Image Editor that allows users to wrap the image with an href. This would cut out a step for people who want to add a link to images. (This functionality is available in the ckEditor)

1. Click the 'Calendar' icon button on the date field. The date picker should pop-out. 
2. Now whilst the date picker if out change the iPad orientation to Landscape mode. 
3. Check the date field again. Notice that the Calendar icon button has been duplicated.

Problem: We really want to fit Gantt's on particular paper sizes (def. landscape A3); however, using the paperSize option doesn't really work as the output (font size, row heights, etc.) end up being too big and not suitable.

And for the majority of the time, paperSize set to auto creates an output (font size mostly) too small.

Rock and a hard place... 

Solution 1: When pdf.paperSize is not set to auto i.e. A3, A4, etc. Allow a percentage scaling to be set, ideally individually, on X and Y.

Solution 2: Scale fonts and scale timeline on X axis maintaining taskList width.

Ultimately, get a large plan to fit on landscape A3.

In the Gantt control there should be events for expand/collapse to provide things like on-demand loading of subnodes for large project-trees

The current list of events associated with PDF creation of Gantt chart data is insufficient. In order to make this control production suitable the following PDF generation events/features would be needed:

1.- Ability to provide progress on the PDF file generation. Right now this can take minutes.

2.- Ability to cancel a PDF generation that is in progress. Right now this is not possible, but would be needed for lengthy operations.

In a grid with 'inline' edit that has rows that are wider the the viewport when entering edit mode the grid now positions on the first editable cell in the grid. This should be the cell that was selected before going into edit mode. In other words the grid should persist its scrolling position.

Using the dataBound event is useful for initializing 3rd party widgets within a template (such as bootstrap-toggle) or to use kendo.bind to bind controls to a model. The issue is that when other rows are expanded the internal _render event is triggered which can recreate an existing row which means that the widget reverts back to standard HTML and the binding is lost.

I have an event handler for when a drop down inside the grid changes that calls .set("MyField", myValue).  Behind the scenes, kendo sets the current cell to the first cell in the grid!  I would like the current cell to be preserved so that the grid works for keyboard navigation as well as point-and-click.

I have recenty found that if users include <html> tags in fields in a form, and this data is then displayed in a grid, if the user then groups by that column, raw html will be displayed. The "suggested" way around this potential huge security flaw is to use a group header template for every string column, ensuring the value is displayed encoded using ${value} instead of the default #=value#.

The default for a cell is ${value}

In a navigatable grid with row selection mode, It should be possible to focus row using arrow keys (up or down) instead of space bar.

Right now when user press arrow keys, only once cell is being highlighted and focused. If user wants to highlight that row then he needs to press spacebar.

this behavior is confusing for end user.
