Connecting a connection to another connection

Hello Telerik staff,

First of all, allow me to thank you for all the help your team has provided me. After implementing custom shapes in my RadDiagram, I discovered that I require to create a connection that allows me to link other connections to it (please, see attached image). I have perused the forum and the documentation, but I have not found any clue that could lead me to a solution.

Thank you very much.

Creation of a custom tool and utilization of custom RadDiagramConnection along with the ConnectorTool

Dear Telerik staff,

I am trying to insert a customized connection using the default ConnectorTool into my RadDiagram. However, this seems near impossible because the library does not expose a method to do that, as WPF does (https://www.telerik.com/forums/using-connection-tool-to-draw-custom-connection). Consequently, I decided to create a custom tool, but it is not working. I need a tool that provides the same functionality as the ConnectorTool, but that employs a customized connection that contains its own visual traits and a set of extra properties/variables.
My current code is as follows:

public class CustomTool : ToolBase, IMouseListener

{

public CustomTool(string name) : base(name)

{

this.Name = name;

}

IConnection currentConnection = null;

Point lastPoint;

public virtual bool MouseDown(PointerArgs e)

{

try

{

if (this.ToolService.ActiveTool != null && this.ToolService.ActiveTool.Name.Equals(this.Name))

{

HitTestService hitTestService = MainMenu.getDiagram().ServiceLocator.GetService<IHitTestService>() as HitTestService;

if (this.currentConnection == null)

{

this.currentConnection = new CustomRadDiagramConnection(System.Drawing.Color.FromArgb(150, 45, 90), "test");

if (hitTestService.ShapeUnderMouse != null)

{

this.currentConnection.Source = hitTestService.ShapeUnderMouse;

}

this.currentConnection.StartPoint = e.TransformedPoint;

this.currentConnection.EndPoint = this.lastPoint = e.TransformedPoint;

this.Graph.Items.Add((RadElement)this.currentConnection);

hitTestService = null;

return true;

}

catch (NullReferenceException)

{

MessageBox.Show("Not working");

}

return true;

}

protected override void OnActivated()

{

base.OnActivated();

this.lastPoint = new Point(0, 0);

this.currentConnection = null;

}

protected override void OnDeactivated()

{

base.OnDeactivated();

this.ToolService.ActivateTool("Pointer Tool");

this.Graph.AddConnection(currentConnection);

//this.Graph.Items.Remove((RadElement)this.currentConnection);

this.currentConnection = null;

}

public virtual bool MouseMove(PointerArgs e)

{

if (this.currentConnection != null && this.IsActive)

{

this.currentConnection.EndPoint = this.lastPoint = e.TransformedPoint;

this.currentConnection.Update();

return true;

}

return false;

}

public virtual bool MouseUp(PointerArgs e)

{

HitTestService hitTestService = MainMenu.getDiagram().ServiceLocator.GetService<IHitTestService>() as HitTestService;

if (IsActive)

{

if (hitTestService.ShapeUnderMouse != null)

{

this.currentConnection.Target = hitTestService.ShapeUnderMouse;

}

this.currentConnection.EndPoint = this.lastPoint;

this.currentConnection.Update();

this.DeactivateTool();

hitTestService = null;

return true;

}

return false;

}

public bool MouseDoubleClick(PointerArgs e)

{

return false;

}

Thank you

ContainerShape that "fills" the diagram area and with fixed shapes

I am planning to include two types of radDiagramContainerShape in my project:

1) The first one holds all the shapes that will be created and inserted into the Diagram; hence, it must fill the whole area of the diagram. In other words, it should behave as if it were docked to its parent (radDiagram) in dock.fill mode.
2) The second one will be created each time a "special" shape is instantiated. Then, that shape will be added and locked to it. This container should behave normally with any other shape, but the special one. The special shape must remain fixed to the container.

I have been reviewing the accessible properties and events, but I have not found a way of achieving it yet.

Thank you for your help!

[Solved] Disable Scrolling for Panning in Grid

Hi, How can I disable grid scrolling associated with a panning gesture? I would like it just to work when using the grid's scrollbar. So, while a user is panning, e.g. panning vertically up, I do not want the grid to scroll.

Thanks!

Set default value for Draw Shape and Draw Text.

Hi, how can I set the default value for Draw Shape and Draw Text element. For example I set the default value border thickness=3 , shape color = red, shape fill = transparent. For now, all the setting I need to set at the DrawShapeDialog. Can I hide this pop up? So that user can straight forward to make a draw.

[Solved] Is There A Way to Put Something to Replace a Footer?

The documentation makes no mention of a footer in a virtual grid. Is it possible to put lets's say a label or some other control under the grid - to give a record count after filtering, for example.

[Solved] How to show the portion of dataset which generated values in a cell

Hi, excel have a very nice feature that, when on a pivot, if you double click a cell, it shows the full dataset which is bound to the same cell.

It is possible to achieve the same by using the radpivotgrid?

For example we need to know, when a user double clicks on a cell which is the result of an aggregate (sum, average etc..) what are the rows on the dataset which generated that sum.

Trackbar Range Value Update

I am struggling with an feature that I'd like to implement.

Basically, I'd like a visual cue that indicates the current value of the range as end user changes the value of the range.

My TrackBar has 1440 minutes and I'd like to display what minute they're on without it being guess work.

I attached a screenshot of my implementation of the track bar.

Ideally, I'd like to display a label underneath the TrackbarThumbElement that would update as the value updates and then disappear. Any ideas how I might be able to update the UI with the current value of the range as the end user is manipulating the control?
