RadRichTextBox Document binding giving an error

I have RadDocument which is having some html input.

var provider = new HtmlFormatProvider();
RadDocument _document = provider.Import(some xml text input);

Now I am assigning this _document to the RichTextBox Document.

RichTextBox1.Document = _document ;

While rendering this RichTextBox in UI we are getting the below Exception.

The component 'Telerik.Windows.Documents.UI.Layers.TableDecorationLayers.TableMovement.TableAdorner' does not have a resource identified by the URI '/Telerik.Windows.Documents;component/ui/layers/tabledecorationlayers/tablemovement/tableadorner.xaml'

And StackTrace is:

Shift-tabbing problem

When using KeyboardNavigation.IsTabStop="true" in a RadMaskedInput textbox, you cannot shift-tab out of the control.
If I remove that it shift tabs OK.

Is that a bug?

Button text size in Q2 2015

Hello,

after updating to Q2 2015, I have a strange behavior on my ribbon: the first time a tab is displayed, the text of the buttons are not correct (they are slightly larger than they should do). This behavior dissappears after selecting another tab (which shows the same problem the first time) and coming back to the previous one.

Very strange...

RadObservableCollection.AddRange bug

Hi Guys,

I'm doing a lot of work with data in multiple threads and the RadObservableCollection is a great little gem.

However I have discovered an a small bug in AddRange method of the RadObservableCollection that has major implications. The AddRange method does not honour the manually set SuspendNotifications state and calls ResumeNotifications inside the method without first checking if already suspended. Any UI thread bindings monitoring for updates hit a fatal error condition.

As a paid subscriber I can change the code manually but this would mean I would have to manually patch every time when new releases are made available. Would it be possible to fix this oversight?

Thanks,

Graeme

TextInput EditTrigger value

Hi,

I’m trying to only allow certain character in some columns (for example no letter in a columns). I’ve manage to do this easily but getting access to the TextBox’s event in the PreparingCellForEdit event.

My issue is that it does not cover the TextInput EditTrigger value, since it that will overwrite the previous value of the field. I’ve managed to get the value (the letter that was typed) from the EditingEventArgs property of the GridViewPreparingCellForEditEventArgs in the PreparingCellForEdit event by casting it to a TextCompositionEventArgs and then reading the Text property but by then, cancelling the event doesn’t not prevent the editor from being display.

Is there a better solution? Ideally I would need the TextInput EditTrigger value in the BeginningEdit event.

Thanks

LookupEdit control by telerik ?

I would like to see a Lookup edit control like this one:

http://community.devexpress.com/blogs/theprogressbar/archive/2010/10/12/new-lookup-editor-control-for-wpf-and-silverlight-coming-in-v2010-vol-2.aspx

I made one with the standard controls of wpf and its slow as hell.

Do you have plans for this control in near future?

Remove GridViewCell border when Grouped
