Problem with LabelOffset and LabelInterval in CategoricalAxis

(I am using Telerik 2013.2.809.40 for WPF)

I have a RadCartesianChart with a Series that contains 30 items (categories are from “2013” to “2032”).

I want to show only the labels “2015”, “2020”,“2025”,“2030” in my CategoricalAxis.

How can I do this?
Setting LabelInterval=5 and LabelOffset=2 does not work (in this case only "2023" and "2028 are shown)

Thanks - Janko

Out of Memory Error

Hello,

I am using a Spline defenition and when I double click the window header to fit the window to the Monitor I get an out of memory error. It looks like it is trying to Redraw the Spline lines. Here is the Stack Trace:

Can't set RadGridview header after upgrade

Hello,
I've upgraded an old wpf application to latest Telerik WPF control version... before I've defined a GridViewCommandRow that will substitute the grouping header to the 2 buttons export/print

the code is taken from a your article and it's

public class GridViewCommandRow

{

public static readonly DependencyProperty IsEnabledProperty =

DependencyProperty.RegisterAttached("IsEnabled",

typeof (bool),

typeof (GridViewCommandRow),

new PropertyMetadata(false, OnIsEnabledChanged));

public GridViewCommandRow(RadGridView grid)

{

RadGridView = grid;

CommandRow = new ContentControl();

CommandRow.SetValue(Grid.RowProperty, 0);

if (ViewCommandTemplate == null)

{

var commandRowTemplate = Generic.GetInstance()["CommandRowTemplate"] as ControlTemplate;

if (commandRowTemplate != null)

ViewCommandTemplate = commandRowTemplate;

}

public ControlTemplate ViewCommandTemplate { get; set; }

private ContentControl CommandRow { get; set; }

public RadGridView RadGridView { get; private set; }

public static void SetIsEnabled(DependencyObject dependencyObject, bool enabled)

{

dependencyObject.SetValue(IsEnabledProperty, enabled);

}

public static object GetIsEnabled(DependencyObject dependencyObject)

{

return dependencyObject.GetValue(IsEnabledProperty);

}

private static void OnIsEnabledChanged(DependencyObject sender, DependencyPropertyChangedEventArgs e)

{

var radGridView = sender as RadGridView;

if (radGridView != null)

{

if ((bool) e.NewValue)

{

// Create new GridViewCommandRow and attach RadGridView events.

var commandRow = new GridViewCommandRow(radGridView);

commandRow.Attach();

}

private void Attach()

{

RadGridView.DataLoaded += RadGridView_DataLoaded;

}

private void RadGridView_DataLoaded(object sender, EventArgs e)

{

if (RadGridView.Items.Count > 0)

{

RadGridView.SelectedItem = RadGridView.Items[0];

}

Grid hierarchyGrid =

RadGridView.ChildrenOfType<Grid>().FirstOrDefault(c => c.Name == "HierrarchyBackground");

if (hierarchyGrid != null && CommandRow.Parent == null)

{

hierarchyGrid.Children.Add(CommandRow);

CommandRow.Template = ViewCommandTemplate;

}

The template is defined here

VisualizationLayer issues with location and listcollectionview

Hello!

I'm trying to implement map control and I use VisualizationLayer, but I have some issues with that...

1. I would like to filter some items which I want to display on the map but when I try to use ListCollectionView I get error "'System.Windows.Data.ListCollectionView' is not a valid value for property 'Source'.". Do you have any ideas why is this happening?
ListCollectionView for InformationLayer works great.

2. In my solution I had to use custom class which implements IMapPropertyAccessor interface but the problem is when I want to update "Location" on the fly, I don't know how to propagate this change to the user interface.
Do you have any suggestion how to do this?

Replace view/viewmodel of already existing TileView item

Hello!

I have added some TileViewItems to my TileView using RegionManager.AddToRegion() and it's working fine (I think RequestNavigate would do the trick also).

Now I would like to allow user to configure each tile separately. One configuration option would require me to change the configured tile to show another view (and maybe use its own viewmodel also).

Is this possible?

Now that I try RequestNavigate to this TileView region it always adds a new TileItem and that is not what I want in this case. I'd like to be able to only change the view/viewmodel for the tile I'm configuring.

Br,

Cannot load document

Hi,
Can You please tell me why this code is not working. In code behind:

private void Button_Click(object sender, RoutedEventArgs e)

{

OpenFileDialog ofd = new OpenFileDialog();

ofd.Filter = "Pdf-Dateien (*.pdf)|*.pdf";

if (ofd.ShowDialog() == true)

{

this.documentStream = new FileStream(ofd.FileName, FileMode.Open);

RadFixedDocument doc = new PdfFormatProvider(this.documentStream, FormatProviderSettings.ReadOnDemand).Import();

this.pdfViewer.Document = doc;

}

}

and in XAML:


<telerik:RadPdfViewer Grid.Row="1" x:Name="pdfViewer" Grid.ColumnSpan="2"/>

System report no errors, simply nothing is showing in viewer.

Can AutoCompleteBox work like a TextBox with Autocomplete?

Hi,

I thought (from the first look it seems so) AutoCompleteBox is what I'm looking for.
Searching the help I found not a single word how to bind Text with this control.

Further investigations brought me to a mix of "SearchText" and "SelectedItems" - which barely works

Anyhow - what I expected was:
a.) A TextBox (with validation and binding for the text)
b.) Suggestions with the possibility to choose (and also change) an item

Or (except for Validation) - the thing you see in Internet Explorer.

Can I do this with RadAutoCompleteBox?

Approach:
User has give a "Reason" for something.
In my Model I have Item.Reason - which must be filled.
Since the resons are often the same - I have a list of default reasons - as suggestions whild entering text.
The user chan choose an existing one - his own one - at the end there is text in the box - which has to be validated (IDataErrorInfo)
If it fails - red markers.....

[Solved] Calendar with Office 2013 theme

My calendar, see attached image, when setting the theme to Office 2013 loses some of the key styling. The days seem to be missing, selected range doesn't show any highlighting, and the current day is not formatting the day fore color.

Any assistance would be greatly appreciated.

<UserControl.Resources>

<ResourceDictionary>

<telerik:BooleanToVisibilityConverter x:Key="BooleanToVisibilityConverter" />

<DataTemplate x:Name="cFontTemplate"

x:Key="cFontTemplateKey">

<TextBlock Text="{Binding Text}"

Foreground="Black"

FontWeight="ExtraBold" />

</DataTemplate>
