Hello,
I need to change in SettingsPane, remove Home Tab and Text, and change the content of Style Tab.
How can I do this?
I saw to projects called CustomSettingsPane, but they are not that clear for me.

Can you help me and give me a simple project to follow?

Thank you.

Synchronizing ChartView and TimeBar

I have a TimeBar in sync with the zoom/pan of multiple ChartViews. I have code that successfully converts between the time ranges of the TimeBar and the Pan/Zoom properties of the ChartViews, and all works well until I try to sync between a TimeBar and multiple ChartViews.

The execution logic goes like this:

Change the TimeBar
TimeBar change event is fired, ChartViews are updated.
ChartView pan/zoom change events are fired. TimeBar is updated, other ChartViews are updated.
TimeBar and ChartView change events are fired. TimeBar is updated, other ChartViews are updated...
etc.

... and so the application hangs from infinite event recursion. The common approach to prevent this is using a bool as a flag to prevent further execution, but this doesn't work. It seems like the assignment of the pan/zoom properties of ChartView objects are delegated through i.e. Dispatcher.BeginInvoke, since the sub-events aren't fired in-between the times where the recursion flag is set.

My current idea is to set the flag to true and set a timer i.e. 100ms later to reset the flag to false, but I'd like to know if there's a less hacky way to do this?

Orthogonal routing service

I was wondering if anyone has ever created a custom router that acts much like schematic capture programs where the connections are all at right angles. If you look at the youtube video (link is below) starting at 4m28s you can see how this works. How would I go about creating an orthogonal routing service like this? What I have done so far is below, which creates two points in the middle of the connection to allow this to sort of work, but it does not handle anything complex such as going around different shapes and adding additional points when needed. Any thoughts?

public class OrthogonalRouter : IRouter

{

public System.Collections.Generic.IList<Point> GetRoutePoints(IConnection connection, bool showLastLine)

{

List<Point> pointList = new List<Point>();

Point start = connection.StartPoint;

Point end = connection.EndPoint;

pointList.Add(new Point(start.X + (end.X - start.X) / 2, start.Y));

pointList.Add(new Point(start.X + (end.X - start.X) / 2, end.Y));

return pointList;

}

Obtaining TimelineItemGroupControl

Hello,

I am using a TimeLine control in which I have several groups.
I'd like to know if there is a way to get the TimelineItemGroupControl over which I am moving the mouse.
In my scenario I am selecting a row from a GridView and drag-and-drop over the TimeLine control, and depending on the group that I drop the row I need to perform some action.

The TimeLine control has the next style:

<Style TargetType="telerik:TimelineItemGroupControl">

<Setter Property="IsExpanded" Value="True" />

<Setter Property="Header" Value="{x:Null}"/>

</Style>

Thanks in advance,

Alberto

TileView with Grid support

Hi all,
I would like to use the RadTileView to present a collection of TileViewItems in a grid layout.
Rather than specifying the widths and heights of the items, I'd like to be able to assign them to a row and column as is done with the standard Grid control.
I know this can be accomplished by replacing the RadTileView.ItemsPanel template however doing so completely breaks all of the drag and drop functionality.
I would create a sub-class of the RadTileView control however all of the drag and drop functionality is private.
Any suggestions on how to do this while preserving the drag and drop functionality would be greatly appreciated.

Thanks.

RadDiagram Save does not save all items

Hi,

I used some code from the Demo, the radpanel with shapes.
When i drag and drop a shape on the diagram and call save, the last added shape is not saved, although it is present in the Items collection of the diagram.
What is the fix for this?
What is missing?

Best Regards

Multiple Target DragAndDrop

Hi.

I have a drag drop setup between a RadListBoxA (type A objects) and a ScheduleView(Appointments)

I use OnDragInitialize on the ListBox like this:

private void OnDragInitialize(object sender, DragInitializeEventArgs args)

{

var leg = ((sender as ContentControl).Content as TransportOrderLegViewModel);

// Convert Data to ScheduleView Payload

var appt = new Appointment() { };

if (leg.Planned)

{

appt.Location = "Test";

}

var payload = new ScheduleViewDragDropPayload(null, new List<IOccurrence>() { appt });

args.Data = payload;

// Create DragVisual

var cc = new ContentControl();

cc.ContentTemplate = Resources.MergedDictionaries[2]["TOLDragVisualTemplate"] as DataTemplate;

cc.Content = leg;

args.DragVisual = cc;

args.AllowedEffects = DragDropEffects.All;

args.DragVisualOffset = args.RelativeStartPoint;

args.Handled = true;

}

In the schedule view I use ScheduleViewLevel1DragDropBehavior : ScheduleViewDragDropBehavior.
In the public override bool CanDrop(DragDropState state) the state.DraggedAppointments shows the appointments , so it all works.

I will point out here that DragDropState is in fact for this converter an Telerik.Windows.Controls.DragDropState.

THE PROBLEM

Now I have to enable that the objects from RadListBoxA( Type A ) can also be dropped in another RadListBoxB (type B)

RadListBoxB already has dragging enabled from other sources , so it uses a SchematicViewListBoxDragDropBehavior : ListBoxDragDropBehavior
What I noticed is that in the override of CanDrop(DragDropState state) , DragDropState type comes from another namespace: Telerik.Windows.DragDrop.Behaviors.DragDropState

Whenever I drag something from RadListBoxA to RadListBoxB the state.DraggedItems has no elements.

I thought of using the payload.SetData on the ScheduleViewDragDropPayload to attach extra data , but it doesn't implement that , as it seems it's a different kind of payload than the ones used in other documentation , for example this:

var payload = DragDropPayloadManager.GeneratePayload(null);

var data = ((FrameworkElement)args.OriginalSource).DataContext;

payload.SetData("DragData", data);

args.Data = payload;

Any suggestions would be much welcome. I'm hoping there is a way of doing it without having to rewrite the whole DragAndDrop between all the other controls that are already working nicely.

Thank you

Custom ValidationResult

Hi there,

I'm developing a view for a model which makes use of DataAnnotation validation. The RadGridView is automatically showing the error messages triggered by invalid input. But, the model's validators are returning a custom implementation derived from System.ComponentModel.DataAnnotations.ValidationResult which contains additional properties. I need to somehow bind those additional properties in the view (e.g. in the GridViewEditorPresenter) but it seems like the RadGridView is transforming the ValidationResult to some Telerik specific class (GridViewCellValidationResult) and of course the additional information gets lost. Is there an easy way (or maybe a work-around) to somehow access the original ValidationResult in the GridViewCellValidationResult-Template?

Regards,
Marcel

Node text to be focused when editable

I am using the mind map of telerik.

I want to add this functionality in the node. The ability that when a node is double clicked it selects all the text in the node and allows the user to start typing and have it replace the text. This will replace the current functionality of having to double click on a node then clicking the textbox to be able to change the text.
