When using the workWeek view with workWeekStart set to a higher value than workWeekEnd (e.g., 6 to 5), the scheduler calculates a work week that does not include the current day. As a result, clicking the "Today" button may not display the actual current date if it falls outside the computed work week range. Instead, the scheduler navigates to the work week defined by the configured start and end days.

Hi Team,

I would like to request a way/demo to have AutoSync for the dataSource and be able to stay in edit mode in the Kendo UI Grid. 

Thank you!

Hello,

I noticed in some of my charts that when I call saveAsPDF, the series.name seems to be just a literal string of the series.name option, even when I use a template.

Please see the attached dojo to reproduce (I based this dojo off of the Chart API series.name as template dojo example).

https://dojo.telerik.com/ZgsUVIjM

I noticed that this behavior starts in 2024.4.1112. Prior versions evaluated the template for the PDF.

I do have a workaround for this, which is included in comments in my dojo. I just exportPDF and then use kendo.saveAs.

Additionally, I noticed that the bars in the chart are at 0 in the PDF. I'm not worrying about that at this time, I'm exclusively interested in the series.name template being evaluated on saveAsPDF.

Here are some screenshots of the dojo and resulting pdf for v2024.4.1112:

 

 

Here is a screenshot of the pdf when the same dojo is run on 2024.3.1015:

Please let me know if you'd rather I paste the dojo code directly into this ticket, or attach as a code file.

Thanks!

When the autoAdjust option of the DatePicker is set to false, and the user types a date that is beyond the min/max restrictions, there should be a built-in validation message indicating that the typed date is invalid, to prevent the user from submitting a null value for that field.
