I have a window with a TabControl that has three TabItems. This TabControl is the main control in the window, and I want to size the window based on this TabControl.

If I set SizeToContent="WidthAndHeight" on the window, the window changes size when I select a tab which has content that takes more area. I want the window to start at a fixed size based on the TabItem that will take the largest amount of space. This is not the starting tab.

A TabItem's ActualWidth is the width of the button. The content of an inactive TabItem (a grid) has an ActualWidth of 0 and a Width of NaN because it is not being displayed.

How can I set the window to a fixed size based on the content of the largest TabItem, which is not selected? This would preferably happen at Window_Loaded or Window_ContentRendered.

I've got the following radgridview control with a default sort descriptor on it:

The ItemsSource is bound to:

Whenever the usercontrol is first loaded - the sortdescriptors work, but then any future loads of the usercontrol, the sortdescriptors/filters get lost - I've tried adding a Rebind to the GV on the usercontrol loaded but this doesn't make a difference.

Hi,

We started toreplace our controls by telerik ones and noticed that the combobox wasn't getting the background of the theme we are using (Office 2016). It was keeping a gray gradient background.

After some investigation with the XAML forTelerik.Windows.Control.Input, the style for NonEditableComboBox consists of a grid with two borders and a RadToggleButton inside of it.

After some investigation, I noticed that adding the following lines to the toggle fixed my problem:

Background="{TemplateBinding Background}"
Height="{TemplateBinding Height}"

(Height had to be added for the highlight border as well)

Is this a bug? Or the expected behavior is that when using a RadComboBox the developer wont be able to get the background from the theme or be able to set the height?

Thanks!

Radgridview ist filled with data from database. CRUD works fine.

The RadGridview doesn`t show any changes made outside in the database.

Adding Mode=TwoWay cause readonly error of the QueryableEntityCollectionView data binding

We are showing a that represents a customers budget weeks which can start (WK 1) on any day in the year and are also not always 52 WKs/12 months.

It appears a provider is not the correct approach as the weeks are not bindable, hence the delay to get them from a means the data is not available when the provider is calling its format and interval requests.

Is this achievable?

Thanks,
Maurice

Hello,

Is it possible to set the document of RadPDFViewer from an XAML StackPanel?

I want to generate a PDF document from an XAML section and pass it to the PDF viewer.

Regards,

Sam.

Our product use diagram to realize  a workflow, when there are too many nodes and links in the diagram， it looks very crowded ,  i wish to set some nodes and links as a group which has only one input link and only one output link, and then  i can fold the group to save space, i can also unfold the group 

Is any way to resolve this issue?

Hello,

I use save/load functionality of Docking. I would like to save content of each RadPane to the same file where layout stores, so I would like to get something like this:

I found an old answers in the forum which say that it is not possible. Is there a chance that something changed?

If it is not possible maybe you could suggest a solution? I wanted to store the layout and content in one file.

Thank you in advance
