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="􏀕"
Foreground="Red" />
<!-- Primary (front) layer -->
<telerik:RadGlyph
Font="fads"
FontSize="40"
Glyph=""
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=""
Foreground="Blue" />
<!-- Secondary (back) layer -->
<telerik:RadGlyph
Font="fads"
FontSize="40"
Glyph="􏀕"
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)}");
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I found a forum post from 2015 which seems a bit out of date.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
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.

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

I use RadRichTextBox (WPF) to edit HTML documents.
These contain images with annotations.
It works as expected (except for the context menu popping up when I mark an image) and I can position the images according to my needs.
See Before.png where the red arrow points to something in the image.
When I save the HTML and load it into the RadRichTextBox again the image positioning is totally gone. See After.png
Am I missing something or does the HtmlDataProvider simply not work as expected?
Is this the best place to report bugs?
This is with 2024.4.1213.462.
To duplicate the issue:
Expect the following exception to be raised
Name | Value | Type | |
