Hi,

is it possible to set the search field below the columns in the WPF grid like it was in the WinForm grid? Without clicking the filter button?

Had migrated from .Net Framework to .Net8 and of course updated Telerik references, and I'm facing this problem rendering the chart.

using Telerik.Windows.Controls.ChartView;
using Telerik.Windows.Controls.Legend;

namespace Manager

    public partial class CustomChartControl : UserControl, INotifyPropertyChanged
    {
        private const int YAXIS_STEP_NUMBER = 8;
        private ChartSerieCollectionVM _viewModel;
        private string _title;

        public LinearAxis LeftAxis { get { return chart.Resources["leftAxis"] as LinearAxis; } }
        public LinearAxis LeftCAxis { get { return chart.Resources["leftAxisC"] as LinearAxis; } }
        public LinearAxis RightAxis { get { return chart.Resources["rightAxis"] as LinearAxis; } }
        public LinearAxis RightCAxis { get { return chart.Resources["rightAxisC"] as LinearAxis; } }

We have an application that modifies Word documents using a template system. In our Word template, we use placeholders like #NOTES# to mark where dynamic content should be inserted.

In our app, we define the content for #NOTES# using a RichTextBox, which allows formatting such as bold, italic, and underline. When we replace the placeholder using:

editor.ReplaceText("#NOTES#", importedSections);

…the basic formatting is preserved correctly in the final Word document.

However, when we apply a style like Heading1 to the text in the RichTextBox, that style is not carried over to the final Word output. We are using the following code to handle the import:

var importer = new DocumentElementImporter(document, flowDocument, ConflictingStylesResolutionMode.UseTargetStyle);

Despite this, the style (e.g., Heading1) is not applied in the resulting document. Is there something we’re missing to ensure that styles like Heading1 are preserved during the import?

Any help or guidance would be greatly appreciated!

Thanks in advance.

I recently found that you cant follow shortcuts to folders in the RadSaveFileDialog. We have several end users that have created shortcuts to folders and when they try to open those folders the dialog just selects the shortcut file instead and returns.

There is an option called DereferenceLinks in the OpenFileDialog which seems to do the job but this is not available on any other dialogs.

Is there a work around for this or can that option be made available on the other dialogs too?

when the RadDiagramShape background is set to  LinearGradientBrush or RadialGradientBrush ,if the GradientStop color is opacity color ,

After exporting the PDF, the transparency effect cannot be displayed,like this from SDK Sample(ExportToPDF_WPF project):

<telerik:RadDiagramShape.Background>
<RadialGradientBrush Center=" 0.5, 0.5" GradientOrigin="0.5, 0.5" RadiusX="0.5" RadiusY="0.5">

The effect after exporting PDF：

I use the SyntaxEditor (v2024.4.1113.48, but also checked 2025.3.813.462) in WPF and want to show a completion list. As soon as I call

completionWindow.Show();

the completion window is shown for a very short amount of time in the upper left corner of the screen (not at the carret position). And after approx 200ms the exception occurs.

The function is

private void ShowCompletionWindow(RadSyntaxEditor codeEditor, string[] candidates)
 {
     try
     {
         var completionWindow = codeEditor.IntelliPrompts.CompletionListWindow;
         if (completionWindow?.Presenter == null)
         {
             return;
         }

         var completionList = new CompletionInfoCollection();
         foreach (var candidate in candidates)
         {
             completionList.Add(new CompletionInfo(candidate));
         }

         completionWindow.Presenter.CompletionListItems = completionList;

         // Validate caret position once more before showing
         if (codeEditor.CaretPosition.LineNumber >= 0 && codeEditor.CaretPosition.LineNumber < codeEditor.Document.CurrentSnapshot.LineCount)
         {
             completionWindow.Show();
         }
     }
     catch (Exception innerEx)
     {
         _log.Error("Exception showing completion window", innerEx);
     }
 }

This function gets called from TextDocument.TextContentChanged event handler. This might be the reason. I want to type and want to show identifieres, that start with the string that the user started typing.

Hi,

I've been working with the RadTreeListView control. I'm very happy with it.

However, I stumbled upon a problem when trying to implement a new feature.

I want to hide the expander button of the "first layer items" (level 0). Technically, it worked by adding a trigger to the GridViewToggleButtonArrowTemplate:

<DataTrigger
	Binding="{Binding RelativeSource={RelativeSource AncestorType=telerik:TreeListViewRow}, Path=Level}"
	Value="0">
	<Setter Property="Visibility" Value="Hidden" />
</DataTrigger>

BUT, this solution leads to a huge gap between the table border and the content of each cell in the first column.

I tried obvious things like applying paddings or margins with negative values or setting the expander button visibility to collapsed instead of hidden. But all of these approaches did not lead me to a consistent solution with a desirable UI. Either, the expander button of child items would not be visible anymore, or there would be a huge indent between level 0 and 1 items.

What I'm trying to achieve is that the expander in level 0 is kind of "wiped out" -> it shouldn't be displayed and there must be no gap. But the expanders for all child items must stay untouched. Therefore, all of the cell content in column 1 would have to be moved to the left by around 20 Px (I guess it's 20 Px, because this is the width of the GridViewToggleButton inside the TreeListViewRowTemplate).

I assume, it's a change which has to be made deeply inside the template. I just couldn't find where yet. All "obvious" approaches didn't lead me to where I wanna get.

Any help is greatly apprexciated!

Best regards,

Alex

Hello everyone,

When I C/P a document from Word to our logiciel I have this crash :

System.ArgumentNullException: La valeur ne peut pas être null. Nom du paramètre : NumStyleLink points to not existing NumberingStyle.

From my little investigations, I've see one points to StyleLink and the other NumStyleLink.

If you have any thoughts I'll be glad to here theses.

Thanks !
