Change color of the spinner

Hi, I would like to change the color of my BusyIndicator. I have been able to change the background and the stroke but I can't modify the "spinner" colors.

This is quite a simple question that have been answered several times but I don't understand how to implement the solutions I saw in my code. Maybe you will be able to explain me the solution for the following code:

<ControlTemplate x:Key="GridViewLoadingIndicatorTemplate" TargetType="{x:Type grid:GridViewLoadingIndicator}">

<Border x:Name="BusyIndicatorBackground" Background="#F1F1F1" Opacity="0">

<VisualStateManager.VisualStateGroups>

<VisualStateGroup x:Name="CommonStates">

<VisualState x:Name="Idle"/>

<VisualState x:Name="Loading">

<Storyboard RepeatBehavior="Forever">

<DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="BusyIndicatorBackground" Storyboard.TargetProperty="Opacity">

<SplineDoubleKeyFrame KeyTime="0" Value="1"/>

</DoubleAnimationUsingKeyFrames>

<DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="BusyIndicator" Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[2].(RotateTransform.Angle)">

<SplineDoubleKeyFrame KeyTime="00:00:01" Value="180"/>

</DoubleAnimationUsingKeyFrames>

</Storyboard>

</VisualState>

</VisualStateGroup>

</VisualStateManager.VisualStateGroups>

<Path x:Name="BusyIndicator"

Stretch="Fill"

Stroke="{TemplateBinding BorderBrush}"

StrokeThickness="{TemplateBinding BorderThickness}"

Fill="{TemplateBinding Background}"

Margin="{TemplateBinding Padding}"

HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"

VerticalAlignment="{TemplateBinding VerticalContentAlignment}"

Width="36"

Height="36"

Data=

"M18,5.0000002 C10.820298,5 5,10.820298 5.0000002,18 5,25.179701 10.820298,31 18,31 25.179701,31 31,25.179701 31,18 31,10.820298 25.179701,5 18,5.0000002 z M18,0 C27.941126,0 36,8.0588746 36,18 36,27.941126 27.941126,36 18,36 8.0588746,36 0,27.941126 0,18 0,8.0588746 8.0588746,0 18,0 z"

RenderTransformOrigin="0.5,0.5">

<Path.RenderTransform>

<TransformGroup>

<ScaleTransform/>

<SkewTransform/>

<RotateTransform Angle="-180"/>

<TranslateTransform/>

</TransformGroup>

</Path.RenderTransform>

</Path>

</Border>

</ControlTemplate>

<Style x:Key="GridViewLoadingIndicatorStyle" TargetType="{x:Type grid:GridViewLoadingIndicator}">

<Setter Property="Template" Value="{StaticResource GridViewLoadingIndicatorTemplate}"/>

<Setter Property="Background" Value="{StaticResource GridView_LoadingIndicatorBackground}"/>

<Setter Property="BorderBrush" Value="{StaticResource GridView_LoadingIndicatorBorder}"/>

<Setter Property="BorderThickness" Value="1"/>

<Setter Property="Padding" Value="0"/>

<Setter Property="VerticalContentAlignment" Value="Center"/>

<Setter Property="HorizontalContentAlignment" Value="Center"/>

</Style>

Thank you,

Antonin Charrier

20. <telerik:PropertyDefinition.EditorTemplate>

21. <DataTemplate>

22. <telerik:RadSlider Value="{Binding IsMarried, Mode=TwoWay}" />

23. </DataTemplate>

24. </telerik:PropertyDefinition.EditorTemplate>

25. </telerik:PropertyDefinition>

26. </telerik:RadPropertyGrid.PropertyDefinitions>

27.</telerik:RadPropertyGrid>

Code Behind

01.public PropGrid()

02.{

03. InitializeComponent();

04. this.PropertyGrid1.Item = new Employee()

05. {

06. FirstName = "Sarah",

07. LastName = "Blake",

08. Occupation = "Supplied Manager",

09. StartingDate = new DateTime(2005, 04, 12),

10. IsMarried = 4,

11. Salary = 3500,

12. };

13.}

Start application and expand the whole window. Resize it back, propertyGrid doesnt adjust.

The root cause is the slider. If i remove the slider, everything works fine. For your reference, please see the attached project

Is this a bug?

double click on OpenFileDialog is raising ItemClick event on RadTreeview

Hi,

I have radtreeview control and when OpenFileDialog is shown on top of that control and an item is selected using double click, the OpenFileDialog gets closed which is the expected behavior as the file has been selected. But also the Itemclick event is fired on the treeviewitem which is exactly behind the point where the double click happened on the filedialog.

Can you please let me know how to avoid the ItemClick event.

Thanks.

how to force single span style for the whole paragraph

Hi I have a paragraph style defined as

new StyleDefinition
{
   DisplayName = "Quotation 1",
   Name = "Quotation1",
   NextStyleName = "Normal",
   Type = StyleType.Paragraph,
   IsCustom = false,
   IsDefault = false,
   IsPrimary = true,
   UIPriority = 4,
   ParagraphProperties =
   {
     LineSpacing = 1.15,
     SpacingAfter = 56.0/3.0
   },
   SpanProperties =
   {
     FontFamily = new FontFamily("Calibri"),
     FontSize = 56 / 3.0,
     FontStyle = FontStyles.Normal,
     FontWeight = FontWeights.Bold,
     ForeColor = Color.FromRgb(193, 43, 103),
   }
};

I have a rad document with multiple paragraphs. If the paragraphs have a default styles I can apply my style to one of them and the document looks like expected. The chosen paragraph is pink and bold.

Unfortunately when the user of the application selects some words in the paragraph make them bold and then not bold again it creates a new span which has exectly the same properties including FontWeight Normal, but after I apply my style only the spans that weren't changed become pink bold while the changed remains Normal.

Is there a way to force span style to the whole paragraph?

Removing entries from Custom Dictionary does not fire event

Hello, we are using a RadRichTextBox with SpellChecker dialog. When a word is added to the custom dictionary, either through the context menu or the SpellChecker dialog, the AddWord event is fired correctly. However, when a word is deleted from the dialog, or the Delete All is selected, no event is fired. We are capturing both RemoveWord and DataChanged events, but they are not called. Our current version of controls may be older, so if this was fixed in a later version, please indicate that so we can proceed accordingly.

Thanks for your help.

Force syntax highlighting - scrollviewers hidden

Hello,

is it possible to force syntax highlighting, after setting expression in ExpressionEditor via property ExpressionText? (coming from binding)
On VisualStudio2013_Dark u can't read the expression without highlighting.

What i'm doing wrong? The scrollviewers bottom on editor categories and selected category items are hidden?
I'm using Telerik.Windows.Themes.VisualStudio2013 2017.1.313.40. The ExpressionEditor is in a GridRow with height of 300. It should be high enough?!

<telerik:RadExpressionEditor Grid.Row="5"

ExpressionText="{Binding RollenExpression.Expression, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"

Item="{Binding Source={x:Static slapz:MainWindowViewModel.Instance}, Path=Users[0]}"

ExpressionChanged="ExpressionEditor_OnExpressionChanged"

x:Name="ExpressionEditor"/>

Thanks for any reply.

Regards
Philipp

Grid columns from collection

I am currently evaluating the GridView control for a project, great product by the way, and have a question on how I can go about implementing the following:

I need to display (in a grid) an employee record with a collection of hours by month, the issue is that the number of months we will be displaying can vary so I cannot use a static template.

EmployeeRecord
   EmployeeName
    ID
   Collection of Hours by month

should be displayed in the grid in the following way:
_________________________________________________________________
ID | EmployeeName | HoursMonth1 | HoursMonth2 | HoursMonth3 | HoursMonth4|...
---------------------------------------------------------------------------------------------------------

Is there a way to do this using the RadControl GridView, add additional columns to the grid for each item in the hours by month collection?

Thanks!
