Radwindow does not handle rotation correctly

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

Question regarding floating

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

RadWindow Maximized state bug on Windows 10 ?

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 ?

Regards

RadDocumentEditor - Insert table with HorizontalAlignment.Center

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)

TextRange rt = search.FindAll("centered bold text").First();

document.CaretPosition.MoveToPosition(rt.StartPosition);

document.Selection.AddSelectionStart(rt.StartPosition);

document.Selection.AddSelectionEnd(rt.EndPosition);

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:

RadDocumentEditor editor = new RadDocumentEditor(document);

// How to get the styles

editor.Delete(false);

Table table = GetSomeTelerikTable();

// How to set the style - especially Horizontal alignment for center/right

// table.HorizontalAlignment = RadHorizontalAlignment.Center;

editor.InsertTable(table);

...

// I tried the following for a fixed value of HorizontalAlignment, but this didn't work:

//editor.ChangeTableHorizontalAlignment(RadHorizontalAlignment.Center);

...

document.MeasureAndArrangeInDefaultSize();

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

Thanks a lot

Accessing the NavigationItemButton for a certain RadRadialMenuItem

Hi!

Is there any way to access the NavigationItemButton associated to a certain RadRadialMenuItem? I would like to show the submenus in case that the parent menuitem is clicked, therefore I need exactly the same behaviour for my menuitem as the NavigationItemButton offers.

It would be great if this would be possible in XAML only.

Thanks in advance.

Binding the colour to BarSeries using ChartDataSource

Hi,

I've followed the example here to colour each point of my BarSeries, but I can't make it work. Instead, all the points have turned invisible. The only difference I've noticied between my code and the example is that I use a ChartDataSource object as my points' source, instead of directly binding my collection to the property ItemsSource.

This is my relevant code:

<telerik:ChartDataSource Grid.Column="1" x:Name="VolumeChartDataSource" ItemsSource="{Binding VolumeSerie}" />

Then, on the series definition:

<telerik:RadCartesianChart.Series>
