The documentation of the Kendo-UI Diagram widget specifies the following signature of the zoom method (as do the corresponding TS typings):

zoom(zoom: number, point: kendo.dataviz.diagram.Point): void;

However, the JS implementation looks like this:

zoom: function(zoom, options)

where options is an object that may contain a field called "point" of type kendo.dataviz.diagram.Point.

When using zoom as documented, it ignores the specified point. This DOJO demonstrates the behavior.

The same way it is possible to make the search case-insensitive by setting columns.filterable.ignoreCase to true, it would be great if there was a way to add a custom filter (e.g. make the search diacritics-insensitive, with a custom function or as part of provided functionality). Thanks in advance.

Hi Team,

I would like request adding automatic line breaks for Kendo UI Charts to help avoid lengthy labels.

Thanks!

I need to get the output of a grid saving to pdf without sending the resulting PDF directly to the user. For example, a PDF export option "localexport: true" which would return the data to code instead of directly to the client.

Currently, the file data can be retrieved using the private _drawPDF method:

        var grid = $("#grid").data("kendoGrid");
        var progress = new $.Deferred();

        grid
          ._drawPDF(progress)
          .then((root) => {
            return kendo.drawing.exportPDF(root, grid.options.pdf);
          })
          .done((data) => {
            console.log(data);
          });

Example: https://dojo.telerik.com/rjEORuHy.

However, the approach does not work well in all scenarios for example, when there are multiple pages - https://dojo.telerik.com/iiifASYZ/2 

Thus, I would like to have a built -in method that will be suitable for all scenarios to generate and retreive the file data, without sending the file to the client.

It will be really useful if we could include a new 'filtering mode' in which operators like 'and' or 'or' are allowed in the filtering input box.

For instance, using the "doesnotcontain" with 'march or july or september' will allow users to exclude multiple conditions in a single filter

Expose autocomplete attribute for Kendo TextBox

Overview

Upon initializing the Kendo UI TextBox, the autocomplete attribute is initially set to off.

While this is suggested on MDN in most scenarios, there are use-cases where it is necessary to set autocomplete to new-password to avoid auto-filling.

Desired Behavior

Extend the API to allow setting the autocomplete attribute. This could be done in a similar way as the inputMode configuration.

Workaround

Use jQuery attr method to set the item in the Ready event

   $(function(){
     $('#textBox').attr('autocomplete', 'new-password');
   });

In my application, I have grids with dozens of hidden fields. 

It would be beneficial if I could filter the available columns similar to what's available in the Windows Forms column chooser:
