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

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?

Test Environment:

Windows 11 Enterprise 22H2 22621.1848.
Narrator
Microsoft Edge Version 114.0.1823.79

Repro steps:

1. Open link https://www.telerik.com/kendo-angular-ui/components/grid/examples/filter-all-columns/?theme=default-main&themeVersion=6.4.0
2. Run Narrator
3. Tab to the table present.
4. Tab to the column header "Contact Name" and move to the column menu present and press enter
5. check if the screen reader is announcing the column menu is expanded.

Actual Result:

When pressing enter on the column menu present beside the "Contact name" column header of the table, Screen reader is no announcing the state of the the column as it is expanded or collapsed because of the role set as link.

Expected Result:

When pressing enter on the column menu present beside the "Contact name" column header of the table, screen reader should be announcing the state of the column menu as it is expanded or collapsed, role should be set as button with expand collapse functionality.

Hi,

We have a requirement to implement a timezone change in our web application, so when user selects a timezone from combobox all date data should be displayed in selected timezone and datetimepickers should work in this timezone.

Kendo DateTimePicker works with js Date object and it is not possible to set any other timezone than local.

There are some workarounds of how to display datetime in different timezone, but it is not possible to select one in different timezone other than local. And Today and Now buttons also selects date in local timezone.

Basically, we have just a limitation that we could not use host directives if the directive is not standalone:

see for example :

https://angular.io/guide/directive-composition-api#adding-directives-to-a-component

and about cdk (they are not ready as well):

Hello Kendo Team, 

It would be great if we could have some differentiation when the user closes the delete dialog for kendo scheduler, that way we could take actions accordingly.

Scenarios
1. By clicking on close icon on top right corner.

2. By clicking on clicking on cancel button.

3. By clicking on backdrop.

input to grid:

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

output in excel file:
