Right align button in toolbar with multiple toolbars and toolbartray

I would like to have a toolbartray with multiple toolbars. In the last toolbar I would like to right align some of the buttons. I can align to the right if there is a single toolbar and no toolbartray but when I add the toolbartray the buttons are no longer aligned to the right. The toolbartray is contained in a grid. Thank you for your help.

Apply theme in a mvvm wpf application (caliburn.micro)

I am just trying to apply a theme in a mvvm wpf caliburn.micro app. I added references for the necessary no-xaml wpf binaries (Telerik.Windows.Controls/Navigation, Telerik.Windows.Data (Binaries.NoXAML), in addition I added a reference to the required theme (Telerik.Windows.Themes.Green) and added the resources in a merged resource dictionary in my app.xaml.

I still can't get theming to work. Using implicit styled controls, I can't see any data displayed, but not using implicit styles everything is ok!

1) what am I missing?

2) And where should I apply e.g. : GreenPalette.LoadPreset(GreenPalette.ColorVariation.Dark) - in my bottstrapper?;

Thanks for your help.

2012Q1 RadGridView implicit style does not show group header

Hi. I have an strange behaviour, but I cannot tell when did it happen. I just have a project with a view containing a radgridview, using implicit styles, but the group header is not shown. Whenever I put another radgridview in the same view without any attribute set, also the header is not shown, but it is shown if I am using it in a view of a new project without implicit styles.

Did anyone got this problem and found a solution?

Thanks.

David.

Implementing ItemCreated in ViewModel (MVVM)

Hello All,
I have a need to implement the ItemCreated event over in the ViewModel for a RadCombobox. I need an example of binding the event to a function. Does anyone know of an example out there??? In my View I have a RadComboBox that is bound to a List<string> in my ViewModel. In the contructor of the ViewModel, I populate this list. I need to handle the case when the user adds a new value to this ComboBox. I saw in the UI for Web docs a mention of the ItemCreated event. I think this is what 'm looking for, but don't have a clue as to how to go about implementing it in the WPF MVVM code. Any clues will be greatly appreciated!!!

Thanks in advance,

Wrong Text on SelectItem

<telerik:RadComboBox

Grid.Column="0"

ItemsSource="{Binding Path=DropDownCollectionView}"

IsSynchronizedWithCurrentItem="True"

DisplayMemberPath="Code" IsEditable="True"

EmptyText="Code"

SelectedItem="{Binding Path=Container.Data, Mode=TwoWay}"

Width="75" VerticalAlignment="Top">

<i:Interaction.Behaviors>

<wpf:RadComboBoxClearTextOnLostFocusWhenSelectedItemIsNull />

</i:Interaction.Behaviors>

</telerik:RadComboBox>

For some reason after set Container.Data ComboBox Text has Object.ToString() value rather than the Object.Code property value however items of combobox dispay proper values.

public TData Data

{

get { return _data; }

set

{

if (_data == value) return;

_data = value;

RaisePropertyChanged();

}

public TContainer Container

{

get { return _container; }

private set

{

if (_container == value) return;

_container = value;

RaisePropertyChanged();

}

RadTreeView sort arrows ?

Hi,

I have some custom sorting for RadTreeView (ASC and DESC)...but I need the indicating arrows to go with them in my TextBlock above that triggers the sorting...Is that possible ? Any help is appreciated.

Barry

//GROUP CUSTOM SEARCH
private void TextBlock_MouseUp(object sender, MouseButtonEventArgs e)
{
isoProvider.LoadFromStorage(groupTreeViewIsolatedStorage); //GET

IEnumerable<GroupVM> groups = GroupTree.ItemsSource as IEnumerable<GroupVM>;

if (GroupTreeViewOrdering.Content.Equals(ConstantsUnit.Key_SortAscending))
{
IEnumerable<GroupVM> test = groups.OrderByDescending(p => p.Name);
GroupTree.ItemsSource = null;
while (GroupTree.ItemsSource == null) {
GroupTree.ItemsSource = test;
}

//GroupTree.ItemsSource = groups.OrderByDescending(p => p.Name);
GroupTreeViewOrdering.Content = ConstantsUnit.Key_SortDescending;
}
else if (GroupTreeViewOrdering.Content.Equals(ConstantsUnit.Key_SortDescending))

PDFViewer Print Not Working Correctly

Hello,

We're having some issues with the Telerik RadPDFViewer not printing correctly. When we were on the UI for WPF version 2016.1.112 the print worked fine. Now that we are on the new version 2016.2.503 the print isn't working as intended.

The problem is if you have a multi page PDF in the PDFViewer and try and print it.

The PDF is converted to a byte array (to save to the database), then made into a MemoryStream, and then is passed to the PDFViewer. When you run the PDFViewer.Print() function it will send the PDF to the printer, but data only actually is printed on the first page and the following pages are just blank pages. The printer spits out the correct number of pages that are in the PDF but the first page is the only one that actually has something on it.

The reason we take the PDF and convert it to a byte array is because it's saved to the database for record and display later. This allows a user can come back later on and load the PDF that was saved to the database. It's loaded in from the database into a MemoryStream then to the PDFViewer.

I can provide a sample project that demonstrates the issue we are experiencing and how we are converting everything around. I would attach it but it wouldn't let me.

Telerik UI for WPF version: 2016.2.503 - May 03,2016

.Net Framework version: 4.0

Thanks in advance,

Kevin
