Release 4.3.0 (06/07/2023) (R2 2023)

I have a page with a Gantt chart and a Button. The button navigates to another page in the app (NavigationManager.NavigateTo()). When I click the button an exception is thrown:

Exception trace: Error: Microsoft.JSInterop.JSException: An exception occurred executing JS interop: The JSON value could not be converted to System.Double. Path: $ | LineNumber: 0 | BytePositionInLine: 4.. See InnerException for more details. ---> System.Text.Json.JsonException: The JSON value could not be converted to System.Double. Path: $ | LineNumber: 0 | BytePositionInLine: 4.
 ---> System.InvalidOperationException: Cannot get the value of a token type 'Null' as a number.

The Planned vs Actual functionality of the Gantt allows you to compare actual start and end dates to originally planned dates.

In Telerik UI for AJAX, you can see the Actual vs Planned feature at work

Currently, tasks can be resized and dragged by hours and minutes. I want to be able to drag and resize them by whole days, so the user can directly snap the task to the beginning of the day and not somewhere in the middle. I am looking for behavior similar to this one.

The Tooltip Template of the Gantt behaves strangely in a WASM application. It flickers and does not display any information. Reproduction in REPL which is essentially a WASM app: https://blazorrepl.telerik.com/QQFEapOg56MCIhIK48.

The issue is not reproducible in a server-side application using the same code.

How to get only the year and date in the Gantt Chart Tooltip template? The DataAttribute is not a valid date string.

<TooltipTemplate>
     <h4>@(((TooltipTemplateContext)context).Title)</h4>
     <h5>Start: @(((TooltipTemplateContext)context).DataAttributes["start"])</h5>
     <h5>End: @(((TooltipTemplateContext)context).DataAttributes["end"])</h5>

</TooltipTemplate>

I want to customize the content of the Tooltip visible while dragging and resizing tasks in the Timeline. For example, display only start and end dates and not hours/minutes.

Please allow the Gantt TimeLine to be read-only and prohibit task editing, resizing, dragging and dependency changes.

===

Possible workaround: Read-only Gantt TimeLine (forum thread)

I'd like to have an OnTaskDoubleClick event for the Gantt tasks, so a I can handle it to include some custom logic instead of displaying a popup to edit the task.

Hello, It should be possible to rearrange the order of the Gantt elements using drag and drop. This function already exists in the TreeList component and is also necessary for us in gantt.

Zooming levels would be great

GanttCommandButton Command="ZoomIn|ZoomOut|ZoomToFit"...>

 

The current Views (Day/Week/Month/Year) are nice, but custom zooming is needed sometimes.

The Timeline should be changed in a way that all entries in the (filtered) list should be fully visible. The zooming factor should always be calculated in a way that all currently displayed entries should be fully visible.

There should be a way to programatically set minDate + MaxDate and the Timeline should automatically zoom to display everything between those Dates.

There should be a way to programatically scroll to a specific day in the timeline.

UseCase 1: Goto Today Button

UseCase 2: Upon clicking on a line in tree list the timeline should display this task in the timeline.

Since there is no "goto today" functionality (which I requested in a separate ticket). It is a pain to find the current timeslot in the timeline by scrolling.

The current timeslot should be highlighted by a specific background color or by a vertical line through the timeline.
