Hello,

For example; when selected it turns green, unselected is red.

This gave me 200+ lines of XAML, but I cannot easily identify what to change, pleasy some guidance.

 

I'm on 2025 Q3 for WPF

how to compile WPF project with environment variables but authentication failes

Hello. I have recently needed to repave my dev box. I got my latest code, setup two environment variables (username and password with the once only visible API key), as well as still have the nuget.config file and adding the proper telerik nuget server to the nuget manager. Unfortunately, I still have something wrong because when I compile, I get asked for my username and password what looks like it's the telerik nuget calls. Please help, this is driving me crazy. I'm just not able to figure this out.

 

I have ensured the nugetconfig is using the right\same environment variables as I have setup in the system environment. And the values are correct. Please help.

RadGlyph with Font Awesome Duotone font

Can RadGlyph work with Font Awesome's Duotone font? For example, we want to render: https://fontawesome.com/icons/house?f=duotone&s=solid

I've tried various things, including:

                <Grid>
                    <!-- Secondary (back) layer -->
                    <telerik:RadGlyph
                        Font="fads"
                        FontSize="40"
                        Glyph="&#x10F015;"
                        Foreground="Red" />
                    <!-- Primary (front) layer -->
                    <telerik:RadGlyph
                        Font="fads"
                        FontSize="40"
                        Glyph="&#xF015;"
                        Foreground="Blue" />
                </Grid>

This just renders an all blue house.

Reversing the elements:

            <telerik:RadTabItem.Content>
                <Grid>
                    <!-- Primary (front) layer -->
                    <telerik:RadGlyph
                        Font="fads"
                        FontSize="40"
                        Glyph="&#xF015;"
                        Foreground="Blue" />
                    <!-- Secondary (back) layer -->
                    <telerik:RadGlyph
                        Font="fads"
                        FontSize="40"
                        Glyph="&#x10F015;"
                        Foreground="Red" />
                </Grid>

I'm using the same technique I use to register regular Font Awesome fonts and have verified the codepoints exist:

        var solidDuotoneFontFilePath = Path.Combine(directory, "Resources/Fonts", "Font Awesome 7 Duotone-Solid-900.otf");
        var solidDuotoneFontUri = new Uri(solidDuotoneFontFilePath, UriKind.Absolute);
        var solidDuotoneFontFamily = new FontFamily(solidDuotoneFontUri, "./#Font Awesome 7 Duotone Solid");
        RadGlyph.RegisterFont(solidDuotoneFontFamily, "fads");

        bool HasChar(FontFamily fam, int codePoint)
        {
            var tf = new Typeface(fam, FontStyles.Normal, FontWeights.Normal, FontStretches.Normal);
            if (!tf.TryGetGlyphTypeface(out var gtf)) return false;
            return gtf.CharacterToGlyphMap.ContainsKey(codePoint);
        }

        Debug.WriteLine($"Primary F015 present: {HasChar(solidDuotoneFontFamily, 0xF015)}");
        Debug.WriteLine($"Secondary 10F015 present: {HasChar(solidDuotoneFontFamily, 0x10F015)}");

Using Telerik Export the data grid value into excel.
Summarize the problem:  In the WPF grid, data is displayed using value converters (IValueConverter). When exporting with TelerikDataGrid.Export(), Telerik uses the raw bound values instead of the converted display values. This causes a mismatch: what you see in the grid is different from what appears in the exported Excel file.

Tried Method: 
Identified the root cause of the issue, the grid shows converted values (via IValueConverter). 
But after export uses raw bound values, will exported.  I need to export the Grid displayed value into the Excel.

M_DataGrid_ElementExporting

private void M_DataGrid_ElementExporting(object sender, Telerik.Windows.Controls.GridViewElementExportingEventArgs e)
        {
            if (e.Element == Telerik.Windows.Controls.ExportElement.Cell)
            {
                var cellExportingArgs = e as GridViewCellExportingEventArgs;

                if (e.Context is Telerik.Windows.Controls.GridViewDataColumn dataColumn)
                {
                    var col = e.Context as Telerik.Windows.Controls.GridViewDataColumn;
                    if (col != null && col.UniqueName == "MomentOfInertia")
                    {

                        var binding = dataColumn.DataMemberBinding;
                        var propertyValue = TelerikDataVis_Doc.GetPropertyValue(e.DataContext, binding.Path.Path);
                        if (binding != null)
                        {
                            object rawValue = e.Value;

                            if (binding.Converter != null)
                            {
                                rawValue = binding.Converter.Convert(
                                    propertyValue,
                                    typeof(string),
                                    binding.ConverterParameter,
                                    System.Globalization.CultureInfo.CurrentCulture);
                            }

                            if (!string.IsNullOrEmpty(binding.StringFormat))
                            {
                                e.Value = string.Format(binding.StringFormat, rawValue);
                            }
                            else
                            {
                                e.Value = rawValue?.ToString();
                            }
                        }
                    }
                }
            }
        }

WebCam Preview Very Jerky With Logitech C920e

This can be duplicated in the Telerik UI for WPF Desktop Examples app.

One of my clients uses a fleet of Logitech C920e cameras to capture photos.  The RadWebCam's preview is very jerky and severely lags behind camera movement on every kind of computer we've tested (all running Windows 11) .  This issue isn't present with the couple other camera models we've tested.

I've tested other webcam photo capture apps on Windows 11 and they all work fine with this camera (no lags, no jerkiness).  This includes DevExpress's "Outlook-Inspired Application" demo WPF app.

ScheduleView file-based saving/loading

I'm looking to load/save the appointments to a local file rather than a database.

I found a forum post from 2015 which seems a bit out of date.

Is there any facility for this and if not what is the suggested route? I don't want to ship a database source within my application.

Many thanks

Filtering bug

There appears to be a bug in the column filter popup. Whenever I change one filter operator, the second filter operator changes to the same value. So I can't do something like GreaterThan X and LessThan Y.

See a video here: https://share.cleanshot.com/6Bn9FwlJ

PDFViewer use ContextMenu with DocumentSource Binding

Hi,

I have this code, thats not working like this.

Because of the DataContext, the DocumentSource wont work, because it needs obviously a different DataContext.
But I need this DataContext for the ContextMenu to work.

Is there a way I can have both? A working context menu and also bind the DocumentSource?

Greetings
Benedikt

RadListBox Drop Line Sizing Issue with DragVisualProvider
Hello!

I'm trying to use DragVisualProvider on my ListBox:
            <telerik:RadListBox.DragDropBehavior>
                <telerik:ListBoxDragDropBehavior AllowReorder="False"/>
            </telerik:RadListBox.DragDropBehavior>

            <telerik:RadListBox.DragVisualProvider>
                <telerik:ScreenshotDragVisualProvider />
            </telerik:RadListBox.DragVisualProvider>          

            <telerik:RadListBox.ItemsPanel>
                <ItemsPanelTemplate>
                    <telerik:RadWrapPanel HorizontalAlignment="Stretch"/>
                </ItemsPanelTemplate>
            </telerik:RadListBox.ItemsPanel>

However, the "drop line" (the blue vertical line that indicates where the item will be dropped) is not sizing correctly. It appears to be much larger than the items themselves, as you can see in the attached image.

How can I fix this so that the drop line fits the size of the other images? Am I missing a property or a specific configuration?

Any help would be greatly appreciated. Thanks!
