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.
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.
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.
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.
Hi,
It will be a good addition to your standalone examples if a Java backend implementation is also added to the list:

As demonstrated by the example of the current version and its screenshot, the title of the legend is black when using a dark theme:
Legend - Chart - Kendo UI for Angular (telerik.com)
The rest of the text is white which leads me to believe that this is a bug. This issue is not present when using a light theme.
Hi Team,
Currently, the Kendo UI for Angular library relies on SVG icons as default icons. This means that developers would have to use a service to change the default icons inside components. This approach, however, does change all icons inside the project and is not suitable for cases where only a particular icon in a single component should be changed.
Therefore, I would like to request a designated property or a specific approach that would allow developers to change particular icons inside particular components.
Current behavior
Currently when calling toDataSourceRequest with a date filter, the following is observed:
- Set a filter with the Date object of Wed Sep 19 2018 00:00:00 GMT+0530 (India Standard Time)
- Call toDataSourceRequest or toDataSourceRequestString with the grid state
- The resulting query string contains datetime'2018-09-19T00-00-00'
- 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:
- Set a filter with the Date object of Wed Sep 19 2018 00:00:00 GMT+0530 (India Standard Time)
- The resulting query string contains datetime'2018-09-18T18-30-00' (append Z if possible)
- On the backend, MVC can bind the DataSourceRequest with DateTime of {2018/9/18 18:30:00} and an offset of 0
minimized the last column to smallest and it's difficult to expand this column. Could you please help how to expand this column . Thanks.
first double click on this column line .
scroll move to first column
Could you please help to solve this?

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

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).
If you have a kendo grid table with some data over multiple pages and you go e.g. to the last page and then reload the data, resulting with less pages - the table is empty and you have to manually click on the first page to see the data. Here is a working example:
https://codesandbox.io/s/upbeat-lamarr-d67m8k?file=/src/app/app.component.ts
Step 1. Go to the last page
Step 2. Click on the button "'Reset data" <- you see no data
Step 3. Click on the first page <- You see the data
Hi, Team!
I would like to have a designated component in the Kendo UI for Angular suite that would provide built-in syntax highlighting and code editing experience for popular programming languages.
Similar to the WPF SyntaxEditor: https://www.telerik.com/products/wpf/syntaxeditor.aspx
We are exporting an Excel from a treelist -> there are merged cells, and the table has lots of rows (~20k).
It's taking forever (it's unusable) and the reason is that there is an O(N^2) bug in the toXML function: each row adds a merged cell range, and the mergedCells array is scanned linearly for every new row.
I was able to fix this by adding a mergedCells hash (I would be happy to create a pull request).
Also, as a related issue, it would be nice to be able to change the compression level on the generated zip file, because the default again takes forever for large enough files.
Currently it is possible to override certain messages of the kendo grid with the KendoGridMessages component.
However, this applies the message to the entire grid at once.
For example assume I have a grid with 2 boolean value columns, I would like to override the filter menu IsTrue & IsFalse messages to another string.
This is entirely possible with the KendoGridMessages component.
After the columns in my grid I might put something like this:
This would work if I wanted both boolean filter menus to display Yes & No.
But lets suppose I have set a template for cells in one of the columns like so:
the cells in this column would now display 'Validated' or 'Not Validated' instead of true/false.
It would make more sense for this column filter menu to have 'Validated' & 'Not Validated' instead of the Yes/No message that has been set to the entire grid.
Currently I would have to choose between one or the other strings for the boolean filter, either Yes/No or Validated/Not Validated.
This is a simple example, and in this case using the Yes/No messages for both wouldn't cause a user too much head-ache, but there are plenty of other more complex use cases where not having individual grid messages could cause confusion.
Here is a Stackblitz where I have mocked the grid:
https://stackblitz.com/edit/angular-qynsrr?file=src%2Fapp%2Fapp.component.ts
In the above Stackblitz I've mocked what I would expect it to work like.
I would expect that you can add a KendoGridMessages in the grid to set a default, and then on each column override it as necessary with another component or another KendoGridMessages.
Would like the API expanded to include support for adding your own tool(s) that would allow you to tag the selected text with custom html tags.
For example, would like to be able to highlight some text, hit the custom button and then "text goes here" is replaced with "<custom>text goes here</custom>". From some documentation research, it looks like you don't support custom tools that would be able to accomplish this, is that correct?
From this previous post, it states that such a thing is not supported?
