Connections: Positioning Text below Shape

Hello there,

we are using the RadDiagram to create a kind of hierarchical view, where the connections should show some information about the connection itself.

I've tried to use the Horizontal-/VerticalContentAlignment for this, but since the different directions of the connections I haven't found a solution that worked for all connections yet.

I've attached a picture of our momentary existing diagram. The text for the connections is correctly placed on connections to the left, but not to the right.

Here is the style we are currently using:

<Style x:Key="EdgeStyle" TargetType="telerik:RadDiagramConnection">

<Setter Property="SourceCapType" Value="Arrow1" />

<Setter Property="VerticalContentAlignment" Value="Center"/>

<Setter Property="HorizontalContentAlignment" Value="Left"/>

<Setter Property="ContentTemplate">

<Setter.Value>

<DataTemplate DataType="diagramStuff:DiagramEdge">

<TextBlock HorizontalAlignment="Left" Margin="-20,10,0,0" Background="#F3FFFFFF" Text="{Binding Description}" />

</DataTemplate>

</Setter.Value>

</Setter>

</Style>

It would be perfect, if the text could be positioned right beneath where the connection "meets" the Shape (I've marked the spot on the screenshot in yellow), but I have no idea how to accomplish this.

Could you please help me out how we could accomplish this?

Docking compass arrows misplaced and inconsistent marking position.

Hello,

I'm having an issue that so far seems to affect only one out of about eight users that have tested so far. When the user drags a pane to the main docking compass and hovers, the highlighted section indicating where the pane will dock to is incorrect. But the pane does end up docking correctly. The real problem is when the user tries to dock to the left root compass. The section does not highlight and letting go of he mouse does not dock to the left. This only happens for one user. The user is on a laptop and remotes into the test server via RDP. The user seems the same results when RDPing into 3 other test servers. The other seven users are also using an RDP session but everything works correctly for them. I've attached an example of the misplaced arrows (you can see that the right root compass arrow is moved in a bit) and hover as well as an example of what it looks like for everyone else.

I have not overridden any behaviors for the docking drag and drop or any styling for the compass. I'm curious if anyone knows of why this would only be happening to one user. My first thought was screen resolution but I do not see anything out of the ordinary for that user.

Thank you,

Tara

Custom RadTabbedWindow creates base RadTabbedWindow when "drag-created"

We've got a custom control which inherits RadTabbedWindow. I.e:

<telerik:RadTabbedWindow x:Class="MyCustomTabbedWindow">...</telerik:RadTabbedWindow>

MyCustomTabbedWindow binds to a viewmodel and so on, and works fine. However, when it creates a new window by dragging a tab out of it, the new window (event.NewWindow) is of the base type (RadTabbedWindow), not MyCustomTabbedWindow...

Is it possible to fix this somehow so that the newly created window is of the correct type? At the moment we've done a workaround which creates the new window in the event handler and cancels the original event, but that feels... like a workaround :)

Any suggestions on how to go about doing this?

Diagram Canvas Size

How to create a Rad Diagram canvas with fixed height and width and get only the positive quadrant (x,y) in the view port?

The issue is when I add shapes to the canvas it can be dragged to any quadrant of the canvas, which I want to restrict.

In any case the shapes should not go outside the positive x,y coordinates. I could not find any setting or implementation related to this any samples.

DisplayMemberPath issue - values not displaying

We currently having issues using the RadMultiColumnComboBox when we change property on the view model which we are binding to.

1. We have multiple items with properties and one property is connected to the ComboBox.

2. We select one item in the view and the connected property is displayed in the ComboBox correctly.

3. We select a different item with the same value in the connected property, but the ComboBox does not display any text (null text).

4. Selecting another item with different value in the connected property results in displaying text again in the ComboBox.

For example items could be employees with a display name (DisplayName) property. We have a list of employees populated as item source provider.

The DisplayMemberPath in the ComboBox is set to the DisplayName property.

The SelectedItem property is set to the employee. We also have three more ComboBoxes on the same page that behave correctly (just binding to different properties) and cause no issue.

Any idea what could go wrong?

Regards, Martin

On Sheet Change Scroll to A1

I would like to always freeze the first physical row and column whenever a sheet is selected. However the Freeze Panes method always indexes into whichever rows and columns are currently in the viewport, which might be anywhere on the sheet. How can I get the viewport to scroll to first physical row and column on sheet change?

System.ArgumentException when adding viewDefinitions to RadScheduleView

Hello,

I'm using a RadScheduleView in my project, and it works fine most of the time. But I have had two cases where I get a System.ArgumentException right at the begining when I load my app, whitout being able to do anything about it.

some details :

my app opens at first on a screen containing a radScheduleView.
the radScheduleView is mannulay set to the user's preference (what views he wants, what dayStartTime / dayEndTime, FirstDayOfWeek etc...) in code behind

so what I do is I clear the ViewDefinitionsCollection and then add exactly the views I want, depending on those settings.

here is the function that adds the ViewDefinitions :

/// <summary>

/// Adds a new ViewDefinition in the Collection

/// </summary>

/// <param name="viewDefinitionId">id of the view</param>

/// <param name="viewDefinitionName">display text for the view (localized)</param>

private void AddViewDefinition(int viewDefinitionId, string viewDefinitionName)

{

ViewDefinitionBase viewDefinition = null;

int activeViewDefinitionIndex = ScheduleView.ActiveViewDefinitionIndex;

switch (viewDefinitionId)

{

case 0: ScheduleView.ViewDefinitions.Add(viewDefinition = new DayViewDefinition { Title = viewDefinitionName, TimerulerMajorTickStringFormat = "{0:t} " }); break;

case 1: ScheduleView.ViewDefinitions.Add(viewDefinition = new WeekViewDefinition { Title = viewDefinitionName, TimerulerMajorTickStringFormat = "{0:t} " }); break;

case 2: ScheduleView.ViewDefinitions.Add(viewDefinition = new WeekViewDefinition

{

Title = viewDefinitionName,

TimerulerMajorTickStringFormat = "{0:t} ",

GroupFilter = obj =>

{

if (obj is DateTime)

{

var day = ((DateTime)obj).DayOfWeek.GetRecurrenceDay();

return (day & WorkingDays) == day;

}

return true;

}

}); break;

case 3: ScheduleView.ViewDefinitions.Add(viewDefinition = new MonthViewDefinition { Title = viewDefinitionName }); break;

}

if (viewDefinition == null) return;

viewDefinition.SetValue(IdProperty, viewDefinitionId);

viewDefinition.SetValue(DayViewDefinition.EnableSmallAppointmentRenderingProperty, true);

ScheduleView.ActiveViewDefinitionIndex = activeViewDefinitionIndex;

}



and the Issue I have seems to lies within this function (see attached screenshot for details on the exception)



do you have any idea what is happening here? (I don't)

as far as I can tell, this code should work fine to add new ViewDefinitions to the collection, but for whatever reason I get this Exception. I could catch it and move on but then again, I'd rather know what goes wrong than try to ignore it.

thanks

Cannot resolve dependency to assembly 'Telerik.OpenAccess

I have tried to migrate one project in a big solution to the new csproj SDK style

But I get this error
Error MC1000 Unknown build error, 'Cannot resolve dependency to assembly 'Telerik.OpenAccess, Version=2013.2.702.1, Culture=neutral, PublicKeyToken=7ce17eeaf1d59342' because it has not been preloaded. When using the ReflectionOnly APIs, dependent assemblies must be pre-loaded or loaded on demand through the ReflectionOnlyAssemblyResolve event.' Reports C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\Microsoft.WinFx.targets

To avoid having nuget packages inside our git repository we have all the telerik packages on our own private nuget server

And it seems that in the old style all the telerik packages inside our Seges.Dms.Telerik package are added individually, but when I look now in "Manage nuget packages" they both have the same.

One "funny" note is that on my machine in the Repository where I changed the code it builds, but if I do a new clone and build again I get the error and so do TeamCity and a fellew programmer

Also when looking at https://www.telerik.com/forums/could-not-load-assembly-telerik-openaccess it sounds like people have installed OpenAccess SDK, but this have never been installed on our Teamcity server or my machine, so didnt find any help in this
