It would be nice if additional template variables where available, the only two: pageNum & totalPages are not enough.

Consider Time of Day & Filename at a minimum.

He have created this dojo to illustrate our point.

https://dojo.telerik.com/@navdeep316/iKAmeDAv

We would like to be able to be able to clone options from the top options and subsequently to be able to edit any cloned (child) option. 

We are unable to figure out a way so that the child/cloned dropdowns can change state.

Is it a bug or a feature? How can we achieve our aim?

Thank you so much,

Dimitris

Every time the user scrolls in a grid with virtual scrolling, the grid asks for the total number of rows satisfying the filtering conditions. This causes the same exact query to be sent to the database multiple times. Instead cache this value and only ask for it if the filters change. 

So with normal scrolling down the grid this will generate the following traffic to SQL:

Select Top 100, Skip 0 from Table where...

Select Count(*) from Table where (returns X number of rows)

Select Top 100, Skip 100 from Table  where... 

Select Count(*) from Table where (returns same X, exact same query)

Select Top 100, Skip 200 from Table  where...

Select Count(*) from Table where (returns same X)

and so on

To see this open a copy of the grid with virtual scrolling:

https://dojo.telerik.com/eDImUhOV 

Scroll the grid down:

In Developer Tools observer the result that is sent back to server includes the same:

__count"830"

every time. In terms this will often generate a Select Count(*) being sent to the server in order to supply the answer for the current filters of the grid. An example when a Select count(*) is generated can be seen in your MVC wrappers, for example, where the toDataSourceResult() will cause this same query to repeatedly be sent to the database with every request for new data (use SQL Server Profiler or similiar to see the unnecessary queries). This is also true for your demo implemenations of the server code when used with Kendo UI.  

For grids with large data sets, as is often used with virtual scrolling, this can be a slow query. 

Instead of asking for the number of rows every time the grid is scrolled, only do so at inatialization and when the filtering conditions are changed (for example use a variable or an event to keep track of the dataSources filters changing).

If the program cannot assume that the same number of rows will be returned, then please implement a setting for developers that we can use to say that the data is not changing.

We look at historical data that are constant and with more than 100k rows, the Select count(*) puts an annecessary strain on the servers.

We could implement caching for this value, but instead the grid should not repetedly ask for the same value multiple times, instead of only when the filters change.

What's a Widget?

Witget is simple a not editable div that can contains some html and that we can put into the editor, look this sample:

https://dojo.telerik.com/@MarcellusZebra/egEyAXoB

The sample is pretty ready to use but something is missing.

- User must be able to resize the widget in a better way

- User must be able to drag widget around in the editor

Widgets Support allow to move kendo editor to a new level where user can use it creating amazing reports, I hope you can accept this request.

Editor using editable Div container is really better, for various reasons, that editor using iframe.

Inline Editor can be the solution, but I want also a nice standard editor as the standard mode.

A simple and good solution can be add a new parameter as "toolbarContainer" that is a dom element where editor put the toolbar.

If noset in standard mode, editor apply standard strategy and put it in a div on top of iframe.

If noset in inline mode, editor apply standard strategy and put it in a flying popup.

if set, toolbar editor put toolbar in the selected area.

Thanks,

marc.

The bug I was talking was when setting tagMode of kendoMultiSelect to single, clicking the clear button (x at right of textbox) doesn’t trigger “deselect” event. Not sure if it’s by design. They fixed a similar bug regarding “change” event - https://github.com/telerik/kendo-ui-core/issues/4649.

While you can set the enabled state of the sheet, you can still perform the selection, columns/rows merge and resizes.

In a grid with virtualization, when just normally scrolling down requests for the exact same data are often sent multiple times after each other. The reason for this is probably that the grid sends an asynchronous request for example Top 100, Skip 200 and then does not keep track of that it is still waiting for a reply for this request, before asking for the same data a short period later. 

Commonly requests for the same data is made 2 or 3 or more times after each other, causing performance problem at the server side and in many cases unnecessary calls to the database. Fixing this should lower the number of requests for data to the server considerably, maybe with a factor two or more with just normal grid operation when the user is just scrolling down to view more data in the grid.  

To demonstrate the problem, open a copy of the virtualization grid demo, for example here:

https://dojo.telerik.com/iXijoyaY

Open the Developer Tools and just observe which network requests are sent to the server. Just scroll down in any way and observe that very often the exact same request is made. A request for the same data has the same Top and Skip values in the parameters sent the server. You can see the servers reply is exactly the same JSON data multiple times after each other.

Solving this performance problem almost completely would seemingly be to in a variable just keep track of the "Latest request" sent, since the problem happens mostly just with normal scrolling in one direction with request sent after each other. So one would need to keep track of that a call for Top 100, Skip 200 has been made, and if the program wants to request the exact same data again, just wait for a reply for the first request, instead of sending a new one. (If needed, send a new request only after a specific timeout for a reply for the first one).

A more thorough solution would be to have a data structure to keep track of the Top and Skip tuples for all the calls to the server that has not yet have had a reply from the server, and not repeat those exact same calls again if still waiting for a reply for the first request.

Creating a timepicker with a min value on a DST start day (e.g. March 10, 2019), before the start time, causes the drop down to options to loop over pre-DST start times:
12:30 AM, 1:00 AM, 1:30 AM, 1:00 AM, 1:30 AM, 1:00 AM....

Expected: Time options should continue through the day:
12:30 AM, 1:00 AM, 1:30 AM, 2:00 AM, 2:30 AM, 3:00 AM....

I noticed the error originally in version "2018.3.1017", but it is still happening in "2019.1.220".

https://dojo.telerik.com/ayamEFuZ/4

If the dojo link doesn't work, here's a screenshot and code snippet.

<input id="timepicker" />
<script>
    $(document).ready(function () {
        // create TimePicker with broken drop down picker options
        $("#timepicker").kendoTimePicker({
            min: new Date(2019, 2, 10, 0, 30)
        });
    });
</script>

Hi,

Would like to suggest 2 features for the spreadsheet which will be very useful

 

1) Ability to delete specific cell (not just the content, but the cell itself). Currently there is way to delete row or columns, but no cell deletion.  When cell is deleted, user should be prompted whether to allow all cells below the deleted cell to shift up, or all cells on the right of it to shift left. Akin to excel

 

2) Format painter. The ability to "paint" the styles (such as font size, boldness) from existing text to another existing text. Akin to excel.

Hello guys,

I am stuck with this problem for some time now. Everything works well with mouse, I can drag and drop column into grouping header normally. But on touchscreens I can't drag it. I am interested if anyone has had this issue?

  • Open the MultiSelect and add some items
  • Use backspace to remove items

Result: The items that were selected, then un-selected still show as selected in the list

This can be reproduced on the latest demo page. https://demos.telerik.com/kendo-ui/multiselect/index

Hi Telerik team.

There is a plan or intention to isolate the Template engine indo a separated file or something?

I like the Kendo UI Template engine a lot, I would use it isolated in a project without kendo, for example. It could even be a isolate npm module.I think it is better than mustache or handlebars imo, because you can deal with pure javascript inside, instead of predefined functions and stuff like that.

Example: https://jsfiddle.net/yfz6he3u/

Cheers.

Hi,

It would be very useful to have a disabelDates() method because the suggestion right now is to destroy the calendar and create it again which works but this approach is not acceptable. We need to set different dates based on the current month in the calendar view:

Thank you,

Export to PDF shows the header commands like "Export to PDF", etc. These should be configurable to not be displayed.

 Similarly, using a .PdfExport event to hide and show the command columns is functional but should be included as a property to avoid the flashing that the hide/show does to a large element.

In the latest Kendo UI commercial zip, there is a file typescript/kendo.all.d.ts.

In the Grid class, a property is missing : the dataItems function.

You should add the bold line :

 

        (...)
        dataItem(row: JQuery): kendo.data.ObservableObject;
        dataItems(): kendo.data.ObservableArray;
        destroy(): void;
        (...)

Hi,

While it is possible to get hold of the current page using common JavaScript techniques, it would be great to have a page() method.

In case you need to get the current page now, here are the suggestions made by Progress Technical Support Engineers:

Thank you,

When the DateInput uses a day-first format, e.g. dd/MM/yyyy, if you try to type in 29/02 the DateInput auto-corrects it to 01/02, which is not intuitive to the user and requires them to go back and fix the date again after typing in a leap year.

The DateInput should allow the user to type in 29/02 until the year portion is not provided.

We want to copy & paste cell velue/text from kendo grid. But we are not able to select the cell text itself for copy. I think once we are able to select the cell text, we can copy than.

This functionality will allow managing the visibility of the menu container, in case its container has overflow hidden.
