I'm using central package management, where my Directory.Build.props has folliwing entries:

when using the manage nuget packages dialog from within visual studio it does not report that any updates are necessary, but the build tells me that (of course) there is a version mismatch,
The dialog even tells me that there is a newer version:
What could be the problem that it doesn't get updated or is not found to require an update?
I using the <telerik:RadDatePicker>
DisplayFormat = (Long or short) only there I need a customer format how we archive.
Example : 1 July 2025, 1 JUL 2025
I am using Telerik UI for WPF 2024 Q4\Binaries.NoXaml\WPF80\Telerik.Windows.Documents.Flow.FormatProviders.Doc.dll (version 2024.4.1106.60) on Windows 11 Pro (24H2). The program is developed using VS 2022.
It simply tries to load and display the attached DOCX file and the component crashes during layout with a null reference exception.
using var instream = File.OpenRead(path);
var openXmlRadDocProvider =
new Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.DocxFormatProvider();
var raddoc = openXmlRadDocProvider.Import(instream);
RadRtb.Document = raddoc;
Word displays this perfectly. Trying to determine if this is a Telerik bug or a "me" problem.
Thanks.

I have a RadMaskedNumericInput as follows:
<telerik:RadMaskedNumericInput Grid.Row="0" Grid.Column="1" Width="55"
Mask=""
FormatString="n2"
Value="{Binding TotalFeedVolume}"
IsClearButtonVisible="False"
/>
When I click on the left of the initial zero, it moves my cursor right in front of the decimal point. This is a bit frustrating, as I couldn't, for example, just easily make it "10" with one keystroke. Any way to fix this?
Hello,
I need to change the color of the RadVirtualKeyboardWindow's close button. At the moment it is not viewable very good. I use Material style around in my application, but it seems that it does not completly fit my needs.
I tried to change the button's beahviour like this:
<Style TargetType="telerik:RadVirtualKeyboardWindow">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="telerik:RadVirtualKeyboardWindow">
<Grid>
<!-- Fensterinhalt -->
<Border Background="{TemplateBinding Background}">
<ContentPresenter />
</Border>
<!-- Schließen-Button -->
<Button x:Name="PART_CloseButton"
Width="24" Height="24"
HorizontalAlignment="Right"
VerticalAlignment="Top"
Margin="5"
Background="DarkRed"
Foreground="White"
BorderBrush="Transparent"
Content="✕"
FontWeight="Bold"
Cursor="Hand"/>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
But that actually lead to a very long button and could not change that either:
What can I try next?
Thanks and best regards,
Ferdinand
