Hello

Could we add a "decade" view for the Gantt chart? (currently goes until Year)

 

If the Blazor Gantt chart schedule items span over many years/decades, the Gantt is unusable and crashes.

Our clients' use case is the management of multiple long-term leases; spanning up to 15-30 years.

 

See the attached image as an example in PowerBI where they have a "decade" view.

Controlling the position of the slider between the TreeList and TimeLine panel
The position of the separator is determined by something incomprehensible.
The user only has to guess that the only way to get to the command buttons is by sliding the slider to the right.
Solution:
Implement the "SliderWidth" property in relative units for the component's slider position.

I would like to cancel the edit of certain tasks based on a condition. 

I would like to use Popup editing, and Inline editing as I am able to do so in the TreeList component. 

When I describe a EditorTemplate on a GanttColumn, I expect it to be shown on entering the edit-mode:

<GanttColumn Field="@nameof(ActivityContainer.TaskName)" Title="@_["_name"]" Expandable="true" Resizable="true" >
    <EditorTemplate>
        <strong>I expect this to see</strong>
    </EditorTemplate>
</GanttColumn>

Expected: Just the string "I expect this to see"

What I actually get:

The default edit box (feels like the EditorTemplate doesn't apply at all?)

Docs (https://docs.telerik.com/blazor-ui/api/Telerik.Blazor.Components.GanttColumn#collapsible-Telerik_Blazor_Components_GanttColumn_EditorTemplate) say, that the GanttColumn has a EditorTempalte.

---

Side effect:

<GanttColumn Field="@nameof(ActivityContainer.TaskName)" Title="@_["_name"]" Expandable="true" Resizable="true" >
    <EditorTemplate>
        <strong>@((context as ActivityContainer)?.TaskName)I expect this to see</strong>
    </EditorTemplate>
</GanttColumn>

error CS0103: The name 'context' does not exist in the current context

 

Context should be there.

It is very strange that while the Gantt component is similar to the gorgeous Grid component, support for row and header templates has not been released.
We await implementation
<GanttColumn>

  <HeaderTemplate Context = @ myContext>

  </HeaderTemplate>

  <Template Context = @ myContext>

  </Template>

</GanttColumn>

Will be released in 3.1.0.

The current implementation of the double-click task edit feature is not an intuitive user interface action.
Also, there is absolutely no need to automatically edit the properties of the task model when you click on GanttColumns.
Give the developer independent control over the behavior of the edit event.
Necessary solutions:
1. Implement support for the "IsEnabled" task model property that disables editing the property for the GanttColumn and double-clicking on the Timeline panel
2. Implement support for the "Edit" command for the GanttCommandButton

Currently, you can initiate task editing by double-clicking on an item. I would like to have different options (like buttons) to initiate editing. 

Gantt dependencies do not render correctly under German (Deutschland) culture

I would like to use the Quarter View for the Gantt

ShowWorkHours in the Gantt timeline

I'd like to have access to the GanttTaskCommandEventArgs, so can easily handle custom command actions.

Expose an OnItemRender event, which is raised for each Gantt Timeline task. The args should allow setting a Class, that will be applied at the topmost element of the item itself.

The new Gantt feature turned out really great. It would be nice if the relationships such as predecessor and successor were added, as well as different relationship types (e.g. start-end or start-start) with corresponding offsets.

Likewise, the representation of the critical path and a baseline.

In the Timeline numeric editor the increase/decrease step is 0.01. However, the increase/decrease step of the Gantt Tree numeric editor is 1.  This allows you to increase the Percent Complete value to higher than 1(standing for 100%) and thus break the component.

The Timeline is not rendered correctly. I have to click anywhere in the Tree to render the Timeline.

Is it possible to change the format of the displayed date at the top of the chart? (See the screenshot) Also, I would like to know what to do if possible.

I would appreciate it if you could hold a reply.

in the demo, the percentage display can be over 100%.
As soon as it is over 100% there, the following error is displayed:

(this also happens because it is always incremented by 1, which then always corresponds to an additional 100%.)

In the meantime, a possible workaround could be to use the built-in validation and set values 0 to 1 for the Range attribute of the Percent Complete field. The attached example demonstrates how to achieve that.
