We have implemented custom timeline intervals for radtimeline which was working fine with earlier version of Telerik framework(2019) but after the upgrade to latest(R3 2022 SP1) Telerik framework, with custom intervals the timeline is not loading when customization is removed it works fine(default timeline intervals).

Is there any change with new framework we should be considering?

We are currently testing out the Telerik Upgrade with Demo version of the framework(R3 2022 SP1). Could this be an issue?

I have a two items in radtimeline for example item 0 and item 1. Both Items are 4 week long duration. Our radtimeline is also a week display for each month. Now Item 1 overlaps item 0 from 3rd week, in this scenario item 1 is not visible on timeline(there are many items on timeline apart from items discussing). Now item 1 will only be visible when I horizontally scroll the timeline view to start from item 1's start date. I have not included MinimumItemGap attribute to my timeline. 

Can we have a understanding regarding the attribute and why such scenario is occurring?

Hello,

I want to know if its possible to update Gantt Tasks when you change a Start Date or End Date from the Grid View part. For example, if I delay Proptotype Task, all the task behind should be delayed the same time as Prototype.

Hi,

Is there any way I can select (clicking on) relationships in a RadGanttView so I can remove the relation between two tasks? (whether it's with right click -> delete or with a RadRibbonButton)

I am trying to achieve the following behavior:

1. Wheel will control vertical scroll

2. Horizontal scroll will be visible with resize controls (zoom in and zoom out)

 

Is this possible?

I would like to tweak the timeline to have it work as a "slider" for a video editing like behavior. I have made some tests and tweaks but there are a couple of points I don't manage to tweak:

1. Having a thumb position which can be set by click.

I have managed to display a bar that can move from code using the annotations and a negative margin but I would like to know if there is a way to make it work like a slider thumb (i.e. click or drag&drop)?

2. I have some trouble to find how to use custom interval type to display the text every X seconds but keep some ticks at a smaller interval (see timeline 1).

3. Is it possible to display only specific times (for example beginning and ending time) either on the ruler or as on timeline 3 image?

Note that I am using the NuGet packages and Fluent Dark Theme.

 Hello,

In my application I need to update the ItemsSource every few seconds, I would like to know what would be the best way to perform this.

I might have up to 600 items divides

I have an ObervableCollection object, every time I receive new data I clear the ObervableCollection object and then I add the new data, something like this:
 

ObservableCollection<myData> myCollection = new ObservableCollection<myData>();
  
// Format the data the way I need it
  
myCollection.Clear();
  
foreach (myObject item in DataObject)
{
  myCollection.Add(new myData()
    {
        property1 = item.property1,
        property2 = item.property2,
        property3 = item.property3
        // Operations for other properties
​
 
    });
}

I wonder if it would be better to update my ObervableCollection object (update existing items, add the new ones, and delete those that no longer exist) than clear and add all again.

What I want to achieve is to reduce the rendering time.

I hope you can give me some advice.

Thanks in advance,

Alberto

Hello,

during our development process we've been facing some problems with
one of your products (RadTimeline for WPF).

Situation:
Using the RadTimeline in WPF we have been trying to display expandable/collapsible timeline items,
the general idea is that each timeline item consists of a label and a RadExpander which contains a list of additional information, the size of the list varies from each timeline item to the next.

And while the timeline items themselves work as intended, their positioning on the timeline doesn’t.

While all items are collapsed, their positioning on the timeline is correct,
but when one or more items are expanded, the positioning of these items gets inconsistent,
with some items overlapping others and/or items moving down horizontally.
The hight of the timeline itself seems to increase disproportionally when items are expanded, even if there would have been enough place for them to be displayed on the timeline without its height being increased.

We would like to know if it is possible for timeline items to have different sizes,
And should this not be supported by the RadTimeline out of the box,
is there a way to modify the behaviour based on which the items are positioned on the timeline.
