Hi,

Not sure where to put this issue so general discussion perhaps the best place.

I'm using a MVVM model, with the telerik controls WPF TreeView, WPF GridView, WPF DataForm. 
As a data backend I'm using Entity Framework code first. This mock-up project works really great.

I'm having an issue with filtering the data of the QueryableEntityCollectionView which I use as a source of the WPF GridView and WPF DataForm.
Filtering is defined as FilterDescriptor filterDeleted = new FilterDescriptor("IsDeleted", FilterOperator.IsEqualTo, false); works just fine.

Now I want to filter on a property of a subobject; Person class has a property Club. Club is also a class.
As the FilterDescriptor is not able to filter on FilterDescriptor("Club.Id", FilterOperator.IsEqualTo, 10);
I've added an Additional propertie in the Model

[NotMapped]
[DisplayName("ClubId")]
public int ClubId         
{             
    get             
           {                 
               return Club == null ? -1 : Club.Id;
           }
}

Defining a FilterDescriptor FilterDescriptor("ClubId", FilterOperator.IsEqualTo, 10) is not working, result is no records at all.
Testing with for example PersonID instead of ClubId works fine.
I've also have a similar ClubId property for calculating Age of person. Filtering on age doesn't work as well. Seems that members not original referencing to table column are not working?

I'am trying to implement a data validation for the columns in my RadGridView. I would like to validate the data that is loaded into the grid, not the data that is entered by the user into the grid. To to this I've written a ValidationRule which returns a ValidationResult and implemented this rule in the binding of the column:

These are the settings I've set on my RadGridView:

The ValidationRule is called when loading data into the Grid and a negative ValidationResult is returned, but the error is not displayed in the Grid. What am I doing wrong?

Hi,

as you can see from the attached images, when i rotate the screen (i am on a surface pro 4 with 200% zoom but it's happening also with 100%) the radwindow (as a mainwindow) does not handle the rotation correctly

please check also the project here https://onedrive.live.com/redir?resid=D2C17D45B1412CBA!114&authkey=!AAkiuRoVn6n7nVo&ithint=file%2czip

the scenario is different if you start the window in landscape or portait mode.

but in both scenario the window can't completely maximize

Hi,

I have built an application with the Telerik WPF UI which is used to host other application using the Win32 SetParent function. Basically I can use it to host a number of other applications, similar as to how Chrome or Edge works. It works fine: I can host any application inside a number of radpanes. To achieve this, I have a WindowsFormsHost with a Panel on it. I use the Hwnd of the Panel to reparent the window of another process.

However, when I start undocking a pane by dragging it, the reparented window suddenly disappears and the pane is empty. I tried to handle this by listening to the PaneStateChange and PreviewPin events but that is not enough. I need to know that the pane will become undocked so I can park the parented window somewhere else while the pane is made to float. Is there a formal way to achieve this?

Thanks

Hi,

I'm using the RadWindow as MainWindow for my app but when I try to maximize it, the RadWindow only takes half of the screen and buttons are hidden (see screenshot 1 and 2).

I can drag the RadWindow to get its size and buttons back.

This behavior happends also in the Demo application of UI for WPF (as shown in screenshots 3 and 4), so I think about a bug on Windows 10.

Is there any workaround for this issue ?

Hello,
I have a RadDocument and want to exchange a specific text against a table with the same HorizontalAlignment and other style properties. i.e.:

some text some text some text some text
some text some text some text some text
             "centered bold text"
some text some text some text some text
some text some text some text some text

(the text "centered bold text" have to exchange against my table withHorizontalAlignment = Center and FontWeight = Bold)

How can I get information about the style settings of the text at the CaretPosition?

The insertion of the table isn't without styles works:

How can I set this style properties for my new table?

Thanks a lot
