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

Scheduled for 5.0.0 (15 Nov 2023) (R1 PI1)

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.

I am trying to make the Blazor Gantt control fill a container width and height.

If I set the height of the Gantt control to 100%, it resizes to fill the container except for the tree part of the Gantt control as it stays at whatever size the window was when it first loaded.

===== ADMIN EDIT =====

Meanwhile, as a workaround, you can add a bool flag that will refresh the whole Gantt upon resizing the container. Here is an example of this approach I have prepared at the following REPL link.

You may notice a little flick with this workaround. However, you can cover it with a short loader.

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.

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.

1. Go to https://demos.telerik.com/blazor-ui/gantt/templates

2. Scroll to the end of the timeline horizontally

3. Move the mouse pointer to timelineTooltip appears in the wrong place

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.

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.
