1. Start using the Kendo Tree View in Angular.

2. Load a large dataset for the Kendo Tree View, observe the time taken to render the Tree View.

3. The timing will increase if the dataset keeps on increasing.

4. Suggest some ways to reduce or optimize it.

This is how I am using the Kendo TreeView in Angular,

The feature request affects built-in filter cell components for primitive types such as StringFilterCellComponent, NumericFilterCellComponent, etc.

The built-in filter cell components currently allow to hide operators, but doesn't allow to hide clear button, which is being shown when a user provides some input to these filters. The workarounds are in the current moment possible, but seems to be not very maintainable, as the most obvious workaround is to control with the CSS the internal stylings of the components, which can change with any patch. I would hope for some toggle, which can control hide/display of the clear button.

The use-case in which someone might want to achieve this, is when the filtering is being cleared only globally for the whole grid. and local clearing is not necessarily desired.

The behavior can be tested on an example or provided example in official docs.

Hello,

I want to request a new control (Powerpoint Viewer) that we can use to slide show Powerpoint (ppt or pptx) files.

the main purpose is to handle the previous and next clicks of slides.

Thanks,

I need access to Sketch support files containing the existing UI elements for Kendo for Angular so that I can create comps for my design. 

Ideally this would be a collection of sketch symbols that match the current Kendo UI design. 

It is really hard to check change log for every component you have. Why not implement common change log for all components.

I already talk to Carl Bergenhem (Product Manager for Kendo UI) about that, and he reply:

"
Great suggestion! I’ll sync this with our web site team and try to see if we can create something like this!

"

As picture says more then 1000 words, I attach propose solution.

input to grid:

@Input()
public additionalExcelExportInfos: { additionalWorksheetTitle: string, 
parameters: { key: string, parameterValue: any }[]
};

output in excel file:

When a detail row is used, the moment you expand one row and scroll, it automatically loads the last items from the dataset.

Ex expand row 1 - start scrolling, and it suddenly loads 5xx th row+;

When grouping is also enabled - expanding the detail row under one group, expands it under all groups.

The stackbliz is from the kendo demo page for virtualscroll (with the added detail row).

We could really do with a file explorer, I believe this is already available in your JQuery suite and is planned for .NET Core.

Syncfusion have already implemented an angular file manager which can use Azure Blob Storage as a backend (though other backends are also available).

In fact the syncfusion file explorer is based on your own component.  After some digging around looking for a similar solution I found their design document for the component which directly refers to the Telerik's own components.  You may want to consider contacting syncfusion on this because it appears to me that they may have breached your copyright. 

Reorder the tiles once the dragged tile goes to the new location.

If it closes up immediately (as it does now) that means things are shuffling around while the user is actually dragging which can be stressful – they’ve immediately hit the point of no return Ideally the original location stays ‘open’ until the user lets go in the new locations. Then it all shifts around.

The status bar is used to represent a summary of the aggregated values of the selected cell.

When using kendoTooltip directive on the upload component - tooltips are positioned in invalid position somewhere on the app.

cancel, delete, retry tooltips.

The internal element has a calculated width - but it only grows in value if slider width changes (responsive or even in CSS with media queries etc).

It permanently stays at the largest size.

Hello,

we are searching for two components that we don’t find in your ANGULAR Library.

These components are:

• KANBAN Cards / TASK LISTS   
• Docking Manager

I have attached some print screens for existing components on the market...

Could you please check if there are any future/planned  developments concerning these two components with Telerik?

Thank you in advance…

These are the numeric symbols returned for a locale and so far the decimal, group and percentSign are the only properties that can be overwritten:

numbers: {
        symbols: {
            decimal: ",",
            group: " ",
            list: ";",
            percentSign: "%",
            plusSign: "+",
            minusSign: "-",
            exponential: "E",
            superscriptingExponent: "×",
            perMille: "‰",
            infinity: "∞",
            nan: "NaN",
            timeSeparator: ":"
}

Please allow customizing the rest of the properties (minusSign, nan, timeSeparator, etc). There are certain projects, where those symbols need to be customized.

Current behavior

Currently when calling toDataSourceRequest with a date filter, the following is observed:

1. Set a filter with the Date object of Wed Sep 19 2018 00:00:00 GMT+0530 (India Standard Time)
   
2. Call toDataSourceRequest or toDataSourceRequestString with the grid state
   
3. The resulting query string contains datetime'2018-09-19T00-00-00'
   
4. On the backend, MVC can bind the DataSourceRequest with DateTime of {2018/9/19 00:00:00} and an offset of ???
   

As you can see, the browser's UTC offset is discarded when constructing the query. This presents an issue when the backend server is running in a time zone that is different than the browser or is invariant. Internally toDataSourceRequest calls formatDateValue which calls toUTC. I propose adding an optional argument that allows us to skip this operation so that the offset can be kept as is, the reason being so that it can later be normalized to UTC without losing the information.

Expected behavior

Calling toDataSourceRequest with the option should produce the following:

1. Set a filter with the Date object of Wed Sep 19 2018 00:00:00 GMT+0530 (India Standard Time)
   
2. The resulting query string contains datetime'2018-09-18T18-30-00' (append Z if possible)
   
3. On the backend, MVC can bind the DataSourceRequest with DateTime of {2018/9/18 18:30:00} and an offset of 0
