RadSplitContainer not reporting docking state or width/height correctly

I have a RadSplitContainer docking in an application and when I do the following it either returns DockedLeft or DockedBottom, however I can see that's not correct:

var docking = RadDocking.GetDockState(container)

If I ask for the width and height, I get fixed numbers, not the actual size of the container:

var width = container.ActualWidth;
var height = container.ActualHeight;

Drag Drop ListBox Dragging Behaviour Improvements

Hi Telerik Team,

While doing the drag and drop functionality, to locate the place of the card while dropping we are having a ORANGE line(drop preview line)refer image in attachment. But we need all the other cards to be re-arranged like below.

Let us consider I'm trying to drag the 5th card between 2nd and 3rd cards. While hovering(drop-preview line will be visibile) between the 2nd and 3rd card I need the 3rd card to be moved a little bit down by making space for the 5th card there.(i.e- iphone drag drop capability's) i.e (below the drop-preview line- empty space has to be there(Size of dragged item) and after that remaining cards must be there) in RAD LIST BOX CONTROL used listbox dragdropbehvaiour and screenshot behavior for drag drop operation's.

Can you provide solution for this.

Thanks and Regards,

Kishore Kumar

ChartView with linear X-Axis, how?

I have List of objects (class with 2 int members for x and y value).
Created ChartView with several line series, sharing 1 horizontal and 1 vertical axis between all of them, but when I'm trying to set horizontal axis type to LinearAxis, it just doesn't show any data. When setting it to CategorialAxis - everything works fine. But only LinearAxis fits my needs.

.NET 5 WPF SCD win-86 System.IO.FileFormatException: Invalid file format. at MS.Internal.Text.TextInterface.Native.Util.ConvertHresultToException(Int32 hr)

This question seems related to .Net, but as I am using Telerik UI WPF noXaml 2021 R2 assemblies. I have doubt that Telerik controls might causing this error.

I have published .Net 5 SCD x-86 wpf application on client machine which has win 7 OS. As client machines are outdated, therefore we provided them self contained deployment.

Our application is importing Telerik UI for WPF noXaml 2021 R2 assemblies, and using Font Glyph. FontResources.xaml is imported at application startup. Other than that application is using default fonts.

As following errors shows, application is unable to create font (may be font not found/ corrupted fonts), and I guess Telerik Font Glyph is using fonts which is not available in older OS like Win 7.

HtmlFormatProvider adds extra empty paragrpah on import. (How to remove empty paragraph "NormalWeb")

When I import html document to HtmlFormatProvider, I noticed empty line at beginning of each paragraph. When I exported same document as html document. I found empty paragraph is added, which causing extra spacing. Our challenge is to remove such extra spaces, so that all text in columns are same aligned.

Following is actual document content

<body><p class="NormalWeb "><span class="s_B0779B8D">some text here</span></p><p class="Normal ">&nbsp;</p></body>

While following is generated html document (First para is not part of actual document. and same rendered in richtextbox editor. which adds extra space on top)

<p class="NormalWeb ">
	<span class="s_DED8E654"> </span>
</p>
<p class="NormalWeb ">
	<span class="s_BCF031D1">some text here</span>
</p>
<p class="Normal ">&nbsp;</p>

I am using following code to import html into editor

using (Stream input = new MemoryStream(Encoding.Default.GetBytes(html)))
{
	HtmlFormatProvider provider = new HtmlFormatProvider();
	provider.ImportSettings = new HtmlImportSettings
	{
		UseDefaultStylesheetForFontProperties = false,
		UseHtmlHeadingStyles = false
	};
	RadDocument document = provider.Import(input);
	editor.Document = document;

	editor.Document.StyleRepository["NormalWeb"].ParagraphProperties.SpacingBefore = 0;
	editor.Document.StyleRepository["NormalWeb"].ParagraphProperties.SpacingAfter = 0;
	editor.Document.StyleRepository["NormalWeb"].ParagraphProperties.AutomaticSpacingAfter = false;

}

For reference I am attaching actual html document, exported html document and rendering in user interface.

ZIndex bindings are ignored

This is a bit odd, as I would expect binding changes would be respected. I'm not sure if it is a bug or not, but its definitely unexpected.

ZIndex is a DependencyProperty of the RadDiagramItem class. Being read/write, I would expect that changes to the ZOrder would be reflected in the RadDiagram. This is not the case.

If this is recognized as a bug, I have a repro project I can send along.

Given a type ModelItem with the following DependencyProperties: Position, Width, Height, Color, and ZIndex (I'll omit that code as it is lengthy).

I have a custom graph which implements IGraphSource<ModelItem>, IObservableGraphSource (again, omitted for space) which I add three items to, which match the example found here.

public MainWindow()

{

InitializeComponent();

var graph = new TemplateGraph();

graph.AddNode(new ModelItem

{

ZIndex = 3,

Position = new Point(80, 120),

Width = 150,

Height = 150,

Color = Colors.Red

});

graph.AddNode(new ModelItem

{

ZIndex = 2,

Position = new Point(180, 120),

Width = 150,

Height = 150,

Color = Colors.Green

});

graph.AddNode(new ModelItem

{

ZIndex = 1,

Position = new Point(120, 20),

Width = 150,

Height = 150,

Color = Colors.Blue

});

diagram.GraphSource = graph;

}

In the UI, I have a style which binds the relevant properties of each ModelItem to a RadDiagramShape.

<Window.Resources>

<Style

TargetType="telerik:RadDiagramShape">

<Setter

Property="Position"

Value="{Binding Position}" />

<Setter

Property="IsConnectorsManipulationEnabled"

Value="False" />

<Setter

Property="Background">

<Setter.Value>

<SolidColorBrush

Color="{Binding Color}" />

</Setter.Value>

</Setter>

<Setter

Property="Geometry"

Value="{telerik:CommonShape ShapeType=EllipseShape}" />

<Setter

Property="Width"

Value="{Binding Width, Mode=TwoWay}" />

<Setter

Property="Height"

Value="{Binding Height, Mode=TwoWay}" />

<Setter

Property="ZIndex"

Value="{Binding ZIndex, Mode=TwoWay}" />

<Setter

Property="ContentTemplate">

<Setter.Value>

<DataTemplate>

<TextBlock

Text="{Binding ZIndex}" />

</DataTemplate>

</Setter.Value>

</Setter>

</Style>

</Window.Resources>

Note that the shape's NormalContent displays the ZIndex.

Finally, I have a RadNumericUpDown that controls the ZIndex of the SelectedItem in the RadDiagram

<DockPanel>

<telerik:RadNumericUpDown

Value="{Binding SelectedItem.ZIndex, ElementName=diagram}" />

<telerik:RadDiagram

x:Name="diagram" />

</DockPanel>

I'll attach a screenshot that shows that, even though the ZIndex has changed, the order of shapes on the diagram has not. In the screenshot, you can see that everything appears as it should be -- the ZIndexes of my models are correctly reflected in bindings of the RadDiagramShape, selection bindings work, and changes in the RadNumericUpDown are reflected in the bindings.

However, changes to RadDiagramItem.ZIndex are completely ignored by the RadDiagram, both when initially added, and forever thereafter. What's the point of the ZIndex property when it doesn't work?

If bug, you are hereby notified. If not, you need this feature request. Either way, I could use some help with a workaround.

RadGridView Export PDF RowHeight and ColumnWidth

Hey guys,

Some of my users want to print a GridView and write things in the printed Grid.
I know, dumb...

The Export is currently done with this:

        public void PDFExport()
        {
            Telerik.Windows.Controls.GridView.IColumnFilterDescriptor tempFilter = ucEndtermintreueDaten.rgvEndtermintreueDaten.Columns["Ausblenden"].ColumnFilterDescriptor;
            tempFilter.DistinctFilter.AddDistinctValue(false);

            SaveFileDialog dialog = new SaveFileDialog();
            dialog.DefaultExt = ".pdf";
            dialog.Filter = string.Format("(*.{0})|*.{1}", "pdf", "pdf");
            dialog.FileName = "Endtermintreue " + MinDatum.ToString("dd.MM.yy") + "-" + MaxDatum.ToString("dd.MM.yy");

            var result = dialog.ShowDialog();
            if ((bool)result)
            {
                using (var stream = dialog.OpenFile())
                {
                    GridViewDocumentExportOptions options = new GridViewDocumentExportOptions()
                    {
                        ShowColumnHeaders = true,
                        AutoFitColumnsWidth = true
                    };
                    options.ExcludedColumns.Add(ucEndtermintreueDaten.rgvEndtermintreueDaten.Columns["Ausblenden"]);

                    ucEndtermintreueDaten.rgvEndtermintreueDaten.ExportToPdf(stream, options);
                }

                System.Diagnostics.Process.Start(dialog.FileName);
            }

            tempFilter.Clear();
        }

My problem is, that the rows are to small and the columns not wide enough to write something in it from hand if printed.
But I don't see any option to set the row height, and if I set AutoFitColumnsWidth to false it just cuts off the text in it.
Is it possible to set these options?
Or maybe do I have to set the RowHeight and ColumnWidth in the element and revert it back to the original values after export?

Greetings Benedikt
