I need to display a dataset of a scanned item where the dataset is a list of 3D values (X, Y and Z)
I want the diagram to display the Image as be a top-down view, using X and Y coordinates from the dataset using the the height (Z) to color encode the point using a color gradient.
Using a 3D RadCartesianChart3D component I have created something similar, see the attached RadCartesianChar3D image.
What I need now is a 2D image, something like what I try to illustrate in the attached ColorEncodedItem image.
What I need to know, is what component I should use for this job.
I expect that using a RadCartesianChart3D will be to CPU intensive for the platform I will be running this software on + I don't know, how to make a top-down view of a diagram using this component

Hello im using telerik version 2021.3.909
I have a RadDocking with a lot of RadPanes that are created with DockingPaneFactory
Most of those panes are FloatingDockable which means when i move my main screen the the 2nd(or any other) monitor those RadPanes stays afloat on the first screen.
I know i can change all of them to docking panels and this will solve my problem, but because i have a lot of RadPanes i cannot place them with Dock.Left/Right/etc
My goal is that all my RadPanes will move when the main window is moving(or resizing)

Hello,
I would like to ask for your help. When creating RadTreeView my ItemContainerStyle is not working. I would like to connect ViewModel IsExpanded with RadTreeViewItem but I can't do it. The component works fine for me if I define a HierarchicalDataTemplate for the Item template as follows.
<Grid HorizontalAlignment="Stretch" VerticalAlignment="Stretch" >
<Grid.Resources>
<HierarchicalDataTemplate x:Key="ItemTemplateTree"
ItemsSource="{Binding Children}">
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding Name}" FontWeight="Bold" />
<TextBlock Text="{Binding Value, StringFormat=': {0}'}" />
</StackPanel>
</HierarchicalDataTemplate>
</Grid.Resources>
<telerik:RadTreeView Name="JsonTreeView"
ItemsSource="{Binding SelectedItemInContent.MediaTreeInfoJson}"
IsVirtualizing="True"
SelectionMode="Extended"
ItemTemplate="{StaticResource ItemTemplateTree}"
/>
</Grid>
But if I try to change the ItemContainerStyle like in the Demo examples "ShuttleControl_WPF", the whole tree disappears. As if it doesn't have a properly defined Style.
<Style x:Key="nodeStyle" TargetType="telerik:RadTreeViewItem">
<Setter Property="IsExpanded" Value="{Binding IsExpanded, Mode=TwoWay}"/>
</Style>The model I use for Items is as follows:
public class JsonInfoTreeModel: ViewModelBase
{
private string name;
private string value;
private ObservableCollection<JsonInfoTreeModel> children;
private bool isExpanded;
public JsonInfoTreeModel()
{
Children = new ObservableCollection<JsonInfoTreeModel>();
IsExpanded = true;
}
public string Name
{
get { return name; }
set
{
if (name != value)
{
name = value;
OnPropertyChanged(nameof(Name));
}
}
}
public string Value
{
get { return value; }
set
{
if (this.value != value)
{
this.value = value;
OnPropertyChanged(nameof(Value));
}
}
}
public ObservableCollection<JsonInfoTreeModel> Children
{
get { return children; }
set
{
if (children != value)
{
children = value;
OnPropertyChanged(nameof(Children));
}
}
}
public bool IsExpanded
{
get { return isExpanded; }
set
{
if (isExpanded != value)
{
isExpanded = value;
OnPropertyChanged(nameof(IsExpanded));
}
}
}
}
Thank you for any help.

I want to save the expansion state of my TreeListView before I reload the data and I use the following code:
foreach (var item in _currentTreeListView.Items)
{
if (_currentTreeListView.IsExpanded(item))
{
expandedItems.Add(item);
}
}
// Data update and TreeListView reload
foreach (var item in expandedItems)
{
_currentTreeListView.ExpandHierarchyItem(item);
}But _currentTreeListView.IsExpanded(item) returns false no matter if the corresponding item is expanded in the TreeListView. What's the problem?

Hello,
I need some advice about RadAutoCompleteBox.
When I click on RadAutoCompleteBox I want to see all possible results and then I will have a option to choose whether I want to select from them or start searching by typing. Searching for text and then selecting works fine, but unfortunately searching with nothing in it doesn't work. When I click on RadAutoCompleteBox all the results are displayed, but I can't select anything from them until I type something. The hover selection works fine, I just can't select anything if RadAutoCompleteBox.SearchText is empty. Could you help me how to solve this? Thank you very much.
I am sending part of my the source code and example (WpfApp1.zip) where it also not working.
...
<controls:RadAutoCompleteBoxFilter x:Key="RadAutoCompleteBoxFilter" />
...
<telerik:RadAutoCompleteBox Grid.Row="0"
x:Name="CaseAutoCompleteBox"
WatermarkContent="{x:Static rs:ResourceText.Start_Typing}"
ItemsSource="{Binding Suggestions}"
SelectedItem="{Binding SelectedItem, Mode=TwoWay}"
TextSearchMode="Contains"
TextSearchPath="Name"
DisplayMemberPath="Name"
AutoCompleteMode="SuggestAppend"
DropDownItemTemplate="{StaticResource CasesSearchAutoComplete}"
SelectionMode="Single"
SelectionChanged="CaseAutoCompleteBoxSelectionChanged"
PreviewMouseLeftButtonDown="OnPreviewMouseLeftButtonDown"
GotFocus="CaseAutoCompleteBox_OnGotFocus"
FilteringBehavior="{StaticResource RadAutoCompleteBoxFilter}"
/> public partial class AddMediaToCase
{
public AddMediaToCase()
{
InitializeComponent();
RadWindowInteropHelper.SetShowInTaskbar(this, true);
}
private void CaseAutoCompleteBoxSelectionChanged(object sender, SelectionChangedEventArgs e)
{
var autoCompleteBox = sender as RadAutoCompleteBox;
CaseInformationStackPanel.Visibility = autoCompleteBox.SelectedItem != null ? Visibility.Visible : Visibility.Collapsed;
}
private void OnPreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
if (string.IsNullOrWhiteSpace(CaseAutoCompleteBox.SearchText))
{
CaseAutoCompleteBox.Populate(" ");
}
}
private void CaseAutoCompleteBox_OnGotFocus(object sender, RoutedEventArgs e)
{
if (string.IsNullOrWhiteSpace(CaseAutoCompleteBox.SearchText))
{
CaseAutoCompleteBox.Populate(" ");
}
}
} public class RadAutoCompleteBoxFilter : FilteringBehavior
{
public override IEnumerable<object> FindMatchingItems(string searchText, IList items,
IEnumerable<object> escapedItems, string textSearchPath,
TextSearchMode textSearchMode)
{
var result =
base.FindMatchingItems(searchText, items, escapedItems, textSearchPath, textSearchMode) as
IEnumerable<object>;
if (string.IsNullOrEmpty(searchText) || !result.Any())
{
return ((IEnumerable<object>)items).Where(x => !escapedItems.Contains(x));
}
return result;

Package: Telerik.UI.for.Wpf.70, Version=2024.2.514
I include all necessary theme files for Windows 11 theme in App.xaml:
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/Telerik.Windows.Themes.Windows11;component/Themes/System.Windows.xaml"/>
<ResourceDictionary Source="/Telerik.Windows.Themes.Windows11;component/Themes/Telerik.Windows.Controls.xaml"/>
...
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
I place a simple Button and RadButton inside MainWindow.xaml. When running in this configuration the buttons are visible, the correct theme is assigned. (see screenshot 1)
When placing Windows11Palette.LoadPreset(Windows11Palette.ColorVariation.Dark); inside OnStartup of Application the buttons disappear during runtime. (see screenshot 2)
What am I missing here? The same is with Fluent theme. Other themes like Office2019 work perfectly.
TIA
Heiko

Hi,
We are creating a table which then gets inserted into a RichTextBox. We need to add a DocumentVariableField to one of the cells, can anyone please advise.
// The field which needs to be added o the table
doc_text.Document.DocumentVariables.Add("1001", addrName);
DocumentVariableField docVariable = new DocumentVariableField() { VariableName = "1001" };
doc_text.InsertField(docVariable, FieldDisplayMode.Result);
RadDocument document = new RadDocument();
Section section = new Section();
TableWidthUnit w1 = new TableWidthUnit(100);
TableWidthUnit w2 = new TableWidthUnit(520);
Table table = new Table();
table.StyleName = RadDocumentDefaultStyles.DefaultTableGridStyleName;
TableRow row1 = new TableRow();
TableCell cell1 = new TableCell();
cell1.Background = Color.FromRgb(174, 255, 190);
cell1.PreferredWidth = w1;
cell1.Padding = new Telerik.Windows.Documents.Layout.Padding(3, 6, 3, 6);
Paragraph p1 = new Paragraph();
Span s1 = new Span();
s1.FontWeight = FontWeights.Bold;
s1.FontFamily = new FontFamily(CGlobals.docu_default_font);
s1.FontSize = Unit.PointToDip(CGlobals.docu_default_font_size);
s1.Text = "Name";
p1.Inlines.Add(s1);
cell1.Blocks.Add(p1);
row1.Cells.Add(cell1);
TableCell cell2 = new TableCell();
cell2.Background = Color.FromRgb(174, 255, 190);
cell2.PreferredWidth = w2;
cell2.Padding = new Telerik.Windows.Documents.Layout.Padding(3, 6, 3, 6);
Paragraph p2 = new Paragraph();
Span s2 = new Span();
s2.FontWeight = FontWeights.Bold;
s2.FontFamily = new FontFamily(CGlobals.docu_default_font);
s2.FontSize = Unit.PointToDip(CGlobals.docu_default_font_size);
s2.Text = addrName; // We need to change this to the DocumentVariableField
p2.Inlines.Add(s2);
cell2.Blocks.Add(p2);
row1.Cells.Add(cell2);
table.Rows.Add(row1);
section.Blocks.Add(new Paragraph());
section.Blocks.Add(table);
section.Blocks.Add(new Paragraph());
document.Sections.Add(section);
doc_text.Document = document;
Many thanks
