Hi,

I need to re-order my tabs programmatically. Is this possible and if so how? If not, is there a workaround?

I have searched the telerik forums and carefully read the documentation, but haven't found it described anywhere.

Thanks!

RadRibbonWindow: problem displaying the icon when text size not at 100%

Hello,
the icon of RadRibbonWindow is not displayed correctly when the text size is not displayed at 100%.
Take a look at the attached screen shots, made with Office2013 theme on Windows 8.1 systems: one at 100%, the other one at 200%.
This is very annoying, because there are more and more high resolution displays.

RadGridView with Telerik.OpenAccessContext as ItemsSource not saving/deleting rows

Hello,

Our company is trying to set up a pretty basic WPF Program with a code-first database (FluentModel) and a RadGridView to edit/add/delete data.
So far, everything works, except for the deleting/adding data part. Editting works just fine.

It's a MSSQL Database that gets all of its mapping and fields from Telerik's FluentMetaDataSource .

The problem, I think, lies in the fact that getting data using OpenAccessContent.GetAll<>() returns an IQueryable.
When using this IQueryable, the button to add a new row ("Click here to add new item") simply doesn't work.
A workaround for this is returning an IList instead using OpenAccessContent.GetAll<Type>().ToList() .
Using this as an ItemsSource instead makes it possible to edit existing items (and they can get retreived using our FluentModel's GetChanges().GetUpdates<Type>() method. However, GetInserts<Type>() and GetDeletes<Type>() is always empty, even though we visually see the data in the RadGridView. The changes simply don't go through.

Am I missing a very simple step? I certainly hope so.

01.<controls:RadGridView ItemsSource="{Binding Units}"

02. x:Name="UnitGridView"

03. CanUserFreezeColumns="False"

04. NewRowPosition="Top"

05. RowIndicatorVisibility="Collapsed"

06. GroupRenderMode="Flat"

07. ShowColumnFooters="False"

08. ShowColumnHeaders="True"

09. CanUserSortColumns="True"

10. ShowColumnSortIndexes="True"

11. ShowGroupFooters="False"

12. ShowGroupPanel="False"

13. GridLinesVisibility="Both"

14. BorderBrush="Transparent"

15. BorderThickness="0"

16. RowStyle="{StaticResource RowStyle}"

17. SelectedItem="{Binding SelectedUnit, Mode=TwoWay}"

18. AutoGenerateColumns="False"

19. SelectionUnit="FullRow">

20.

21. <controls:RadGridView.Columns>

22. <controls:GridViewDataColumn DataMemberBinding="{Binding Id}" IsReadOnly="True"/>

23.

<!-- Fields ... -->

24. </controls:RadGridView.Columns>

25.</controls:RadGridView>

01.public class FluentModel : OpenAccessContext, IFluentModelUnitOfWork

02.{

03. private static string connectionStringName = @"connectionId";

04. public static String ConnectionString{get { return ConfigurationManager.ConnectionStrings[connectionStringName].ConnectionString; }}

05.

06. private static readonly BackendConfiguration backend = GetBackendConfiguration();

07. private static readonly MetadataSource metadataSource = new FluentModelMetadataSource();

08.

09. #region Lists

10.

11. public IList<UnitType> UnitTypes

12. {

13. get { return GetAll<UnitType>().ToList(); }

14. }

15.

16. public IList<Address> Addresses

17. {

18. get { return GetAll<Address>().ToList(); }

19. }

20.

21. public IList<Project> Projects

22. {

23. get { return GetAll<Project>().ToList(); }

24. }

25.

26. public IList<Unit> Units

27. {

28. get { return GetAll<Unit>().ToList(); }

29. }

30.

31. #endregion

32.

33. #region constructors

34. public FluentModel()

35. : base(connectionStringName, backend, metadataSource)

36. { }

37.

38. public FluentModel(string connection)

39. : base(connection, backend, metadataSource)

40. { }

41.

42. public FluentModel(BackendConfiguration backendConfiguration)

43. : base(connectionStringName, backendConfiguration, metadataSource)

44. { }

45.

46. public FluentModel(string connection, MetadataSource metadataSource)

47. : base(connection, backend, metadataSource)

48. { }

49.

50. public FluentModel(string connection, BackendConfiguration backendConfiguration, MetadataSource metadataSource)

51. : base(connection, backendConfiguration, metadataSource)

52. { }

53. #endregion

54.

55. public static BackendConfiguration GetBackendConfiguration()

56. {

57. BackendConfiguration backend = new BackendConfiguration();

58. backend.Backend = "MsSql";

59. backend.ProviderName = "System.Data.SqlClient";

60. return backend;

61. }

62.}

Summary: Data CAN be editted and gets passed to the context's (FluentModel) GetChanges().GetUpdates() list. Inserts/Deletes SEEM to work VISUALLY in the RadGridView, but rows do NOT actually get inserted/deleted and the GetInserts() and GetDeletes() lists are always EMPTY. What could be the cause of this?

Thank you for taking your time to read and help

RibbonView/RibbonWindow NullReferenceException

Hello,

We have a RibbonView that lives inside a RibbonWindow. We had previously been running version 2013.3.1021.40 and everything worked fine. When updating to version 2013.3.1417.40, there is a NullReferenceException error getting thrown when RibbonWindow.Show() is called. Has anything changed regarding these controls, or any idea what could be causing this? Below is the stacktrace:

at Telerik.Windows.Controls.RadRibbonView.<>c__DisplayClass22.<PrepareContainerForItemOverride>b__1d(SetterBase x) in c:\TB\105\WPF_Scrum\Current_HotFix\Sources\Controls\RibbonView\RibbonView\RadRibbonView.cs:line 719

How can I get as many merge formats?

Hi,

I'm looking at the Mail Merge example that came with the "RadControls for WPF Q1 2013 SP1" installation and I can export to 6 different formats (Word, Web, PDF, RTF, TXT and XAML). Now, when I implement the same functionnallity in my application I only see 2 (TXT and XAML). See attached images.

How can I add items to the list or mergeable formats?

Can I pick and choose which formats I can allow a user to export to?

Thanks for your help!

Input problem editing controls in the datagrid

http://www.telerik.com/forums/gridview-templateselectors-and-converters

The code in the above thread works now, but a new problem has arisen.
In our code we are using different templates. When you edit a field with a textbox and press enter, it will go to the next field and open a text box for editing. As we have different templates for different input types this is a problem when the next field has a dropdownlist control or a numeric updown control. It is suddenly possible to write a text string to these controls which of course thrown an exception. When selecting the controls with the mouse this problem doesn't occur.

How can I disable this behavior?

Insert items in edit mode problem

Hello.

As the title says, I'm trying to set a node to edit mode as soon as it's created. The approach I'm using is through WPF binding and styling. Basically, my object has a property called "IsNodeInEditMode", and I have a RadTreeViewItem style that sets this property based on the object it's bound to:

                            <Style TargetType="{x:Type telerik:RadTreeViewItem}">         
                        <Setter Property="IsExpanded" Value="{Binding IsNodeExpanded, Mode=TwoWay}" />         
                        <Setter Property="IsInEditMode" Value="{Binding IsNodeInEditMode, Mode=TwoWay}" />         
                    </Style>         

So, as soon as I insert the item, I also set its "IsNodeInEditMode" property to true, which effectively makes the tree item go to edit mode, however, when I change the name of the newly created item, and press enter, it changes back to the original name, and not what I set after creating it, you can see that in this video:

Behavior video

Can you think of something that might be resetting the name? I debbuged this, and checked the call stack on the Name property Set accessor, but I can't get to the code that makes this change since it's external.

Let me know. Thanks!

Scheduleview Custom DragDropBehavior Source Slots?

Hi,
I am using Scheduleview in a TimelineView to implement a job assignment interface. My resources are the employees and the appointments are acting as the jobs.

Behavior I am trying to achieve:
An appointment is assigned to (resource) "A" and "B". I would like to be able to override the drag drop behavior so that if you drag the instance of the appointment from employee "B" down to employee "C" the result is the appointment assigned to the resource "A" and "C".

So far I have created a custom dragdropbehavior and have been able to successfully override the logic so that when you click and drag it adds the destination resource to the job, but I am unable to remove the resource from which I've dragged. To be clear:

In my overridden Drop routine I am grabbing the state.DestinationSlots and checking to see if the resource of the destination slots exists in the appointment, and if not add the resource to the appointment. Where I am stuck is I need to know which slot the drag originated from so that I know which resource to remove from the appointment. Is there such a way to access the source slots?
