Hello,
I'm not sure if this is a bug or if this just isn't the way to change the OverrideColor for this case. I ran into an error when attempting to use the following:
<telerik:RadToggleButton Grid.Row="0" Background="Transparent" BorderThickness="0">
<telerik:RadToggleButton.Content>
<telerik:RadSvgImage Height="60" Width="60">
<telerik:RadSvgImage.Style>
<Style TargetType="telerik:RadSvgImage">
<Style.Triggers>
<DataTrigger Binding="{Binding IsChecked, RelativeSource={RelativeSource AncestorType=telerik:RadToggleButton}}" Value="False">
<Setter Property="UriSource" Value="{Binding RelativeSource={RelativeSource AncestorType={x:Type local:MainWindow}}, Path=PlusImagePath}"/>
<Setter Property="OverrideColor" Value="Blue"/>
</DataTrigger>
<DataTrigger Binding="{Binding IsChecked, RelativeSource={RelativeSource AncestorType=telerik:RadToggleButton}}" Value="True">
<Setter Property="UriSource" Value="{Binding RelativeSource={RelativeSource AncestorType={x:Type local:MainWindow}}, Path=MinusImagePath}"/>
<Setter Property="OverrideColor" Value="Red"/>
</DataTrigger>
</Style.Triggers>
</Style>
</telerik:RadSvgImage.Style>
</telerik:RadSvgImage>
</telerik:RadToggleButton.Content>
</telerik:RadToggleButton>My intention here is to have the OverrideColor change the color of the svg image I am also setting using UriSource. I get the following error only when going from IsChecked being true to being false.

Perhaps this combination of setters isn't possible? I've attached an example project. Any help is appreciated.
Thank You,
Giuliano
Hi Giuliano,
I am not getting the exception with the project (see attached).
Let me know if I am missing something.
I was using version 2024.1.423. It appears this error is gone in 2024.2.514. Looking at the release notes it does mention for SvgImage:
Which doesn't seem to directly address what I was seeing but perhaps other changes addressed the issue which weren't mentioned. In any case, I'll probably just move to use the latest version.
Thank You,
Giuliano
Hi Giuliano,
Yes, we have fixed some issues with the latest version of the SVG image. Indeed the best approach is to upgrade.
Do not hesitate to contact us if you have other questions.
