Hello,

Since the feature request originates from a private support ticket, I will summarize and give a use case for why the Refresh method is needed and what its main purpose should be. 

Use Case: Update the UI after a change in the data collection of the component.

Currently, if the data collection is updated, the changes will not be directly reflected in the UI. A way to refresh the UI after a change in the collection should be provided.

As an alternative, in order to refresh the data without explicitly calling a refresh method, a new reference to the collection should be passed and the framework will automatically cause a refresh in the UI of the Gantt:

<TelerikGantt @ref="@GanttRef"
              Data="@GanttData">
              // . . . 

@code{
    private TelerikGantt<GanttTask> GanttRef;
    private List<GanttTask> GanttData { get; set; }

    private void AmendData()
    {
          GanttData = new List<GanttTask>(); // populate list accordingly
    }
}

If there are additional use cases that should be covered, do let us know.

Hi, Benjamin,

Hello,

In order for us to provide accurate and helpful enhancements, we would need more information regarding the refresh method. It would be very helpful if you can share a few use cases where the Refresh() method would be used.

Currently, the Refresh() method is intended to cause the component to rerender so that it could recalculate its dimensions, resize, etc. However, we are currently investigating the use case where the method is used for rebinding data to the component. For example, modifying the data collection that does not inherit the IObservableCollection interface. This approach would be implemented in a relatively similar way to the Rebind() method of the Grid.

Looking forward to your feedback.

Kind regards,
