RadMaskedNumericInput not working with ApplicationCommands.paste.

it will show ApplicationCommands.paste value but it is not preserved.

onkeypress or tab change, it will change to old value and new paste value will never updated.

I also used CommandBindings in constructor of RadMaskedNumericInput. but it doesn't work.

CommandBindings.Add(

 

new CommandBinding(ApplicationCommands.Paste, (sender, e) =>

{

double inputValue;

bool isInputNumber = double.TryParse(Clipboard.GetText(), out inputValue);

this.Value = inputValue;

e.Handled = true;

}));

Hello,

i have a gridview with ShowInsertRow behavoir
Grid binded to ObservableCollection.

User clicked fixed New row.
i tried to add or delete rows to/from my observable collection in this time(grid is focused on fixed new Row, but user dont makes entries) and dont see any updates.

Our application MainWindow is derived from RadRibbonWindow, our dialogs and other popups are derived from RadWindow.

RadWindow applies theming to its non-client area, RadRibbonWindow ignores the current theme and has the stock Win7 Aero chrome. This inconsistency looks ridiculous. How do we get it so that it is consistent?

We can easily make it so that our dialogs do not have the themed non-client area by deriving them from Window instead of RadWindow, but then the selected theme is not applied by all of the dialog's controls which looks even worse.

What would you suggest?

Hi, I'm trying to drag XML elements from one RadTreeView (call it templateView) to another RadTreeView (contentView), and reordering of the XML elements in the contentView.
A drag operation from the templateView to the contentView should only be a copy operation; the templateView should never change its contents.

Looking through the documentation it appears that RadDragAndDropManager is not supported anymore, but if I look through the samples, for example the TreeView Drag And Drop sample in the WPF Control Example app (and in the examples included in the source), and even in the documentation (http://www.telerik.com/help/wpf/radtreeview-how-to-implement-drag-and-drop-between-treeview-and-other-controls.html), it seems the only samples are RadDragAndDropManager. And the DragAndDropManager samples I found are lacking some of the defining features of RadDragAndDropManager such as the insertion marker (above, inside and below).

So which of these frameworks should I go for? The supported one, without samples, or the unsupported one, with samples?

I have a user control which is just a RadGrid. But the grid is huge where it has 50 columns and for rows i guess not much but 100 rows  and the issue is the same for 20 rows. Where i change the main content or show and hide or drag out and drag it back in it takes a long time and makes pauses while docking or docking out. 


Is there any way i can reduce this pause or any workaround for this issue.

I'm encountering an exception when I call Application.Current.Shutdown in my app. The exception is:

Message
"Cannot set Visibility to Visible or call Show, ShowDialog, Close, or WindowInteropHelper.EnsureHandle while a Window is closing."

Stacktrace

For what it's worth, this app uses Prism and this is a call made via an ICommand on the Shell's viewmodel. As such:

ShellViewModel.cs (snippet)

Without over-complicating matters, the CanClose property is implemented by each screen in the application and will raise a RadWindow dialog prompting for confirmation if there are changes on that screen. Based on our implementation, all of that prompting should be complete before the Application.Current.Shutdown is called so we're not sure what's happening and we can't seem to catch this exception anywhere. It feels like it might be a race condition, but we're not sure where.

Any ideas?

I am using dynamic layers to retrieve data depending on the zoom level and it's working great. However, the user would like to be able to hide certain map pins by checking a show/hide checkbox on the form.

Is it possible to hide items on a dynamic layer? Or even set the visibility of the layer?

I did think about refreshing it's datasource but I cannot find a way to force the map to rebind, I could move the map center programmatically which would cause the ItemsRequest to fire but that seems like a hack.

Is there a way to force a rebind of the data or hide the pins?

Many thanks,
Mark

Hello!

why the header=2222222,press F2 not work?

Hello,

i would like to use the WPF Richtextbox to display some "News" inside our Application.
This News can be different in size, so i need to split the text to different pages, like in Layoutmode "paged".
But also i would like to display only one page at once.
--> Show Page 1 , Blendover, Show Page 2

The best wold be if i can get the different Pages without this "Page" Style around.

So in short:

I need the Documentsplitting from Paged layoutmode, and the clean View from Flow layoutmode, and get / scrollto the different Pages.

I hope you can give ne an Idea how to perform this.

Best Regards,
