Class
VisualStatesItemPresenter

Represents the custom Control implementation used to visualize the hover and selected state over RadRadialMenuItem.

Definition

Namespace:Telerik.Windows.Controls.RadialMenu

Assembly:Telerik.Windows.Controls.Navigation.dll

Syntax:

cs-api-definition

public class VisualStatesItemPresenter : Control

Inheritance: objectVisualStatesItemPresenter

Constructors

VisualStatesItemPresenter()

Initializes a new instance of the VisualStatesItemPresenter class.

Declaration

cs-api-definition

public VisualStatesItemPresenter()

Fields

ArrowThicknessFactorProperty

Identifies the ArrowThicknessFactor dependency property.

Declaration

cs-api-definition

public static readonly DependencyProperty ArrowThicknessFactorProperty

Field Value

DependencyProperty

ThicknessFactorProperty

Identifies the ThicknessFactor dependency property.

Declaration

cs-api-definition

public static readonly DependencyProperty ThicknessFactorProperty

Field Value

DependencyProperty

Properties

ArrowThicknessFactor

Gets or sets the factor defining the thickness of the arrow part of the VisualStatesItemPresenter as a fraction of the size of the NavigationItemButton.

Declaration

cs-api-definition

public double ArrowThicknessFactor { get; set; }

Property Value

double

The value should be between 0 and 1. If the passed value lies outside this range, it is automatically set to the nearest boundary value.

Example

This example demonstrates how to style the VisualStatesItemPresenter of a RadRadialMenu using an implicit style.

You will need to add the following namespace: xmlns:telerikPrimitivesMenu="using:Telerik.UI.Xaml.Controls.Primitives.Menu"

xaml

<telerikPrimitives:RadRadialMenu.Resources>
    <Style TargetType="telerikPrimitivesMenu:VisualStatesItemPresenter">
        <Setter Property="ArrowThicknessFactor" Value="0.3"/>
    </Style>
</telerikPrimitives:RadRadialMenu.Resources>

IsTemplateApplied

Determines whether the OnApplyTemplate() method and the ApplyTemplateCore() routine is passed.

Declaration

cs-api-definition

protected bool IsTemplateApplied { get; }

Property Value

bool

ThicknessFactor

Gets or sets the factor defining the thickness of the VisualStatesItemPresenter as a fraction of the size of the NavigationItemButton.

Declaration

cs-api-definition

public double ThicknessFactor { get; set; }

Property Value

double

The value should be between 0 and 1. If the passed value lies outside this range, it is automatically set to the nearest boundary value.

        <Setter Property="ThicknessFactor" Value="0.3"/>
    </Style>
</telerikPrimitives:RadRadialMenu.Resources>

Methods

ApplyTemplateCore()

Called when the Framework is called. Inheritors should override this method should they have some custom template-related logic. This is done to ensure that the property is properly initialized.

Declaration

cs-api-definition

protected bool ApplyTemplateCore()

Returns

bool

CanUpdateVisualState()

Determines whether the current visual state may be updated.

Declaration

cs-api-definition

protected virtual bool CanUpdateVisualState()

Returns

bool

ComposeVisualStateName()

Builds the current visual state for this instance.

Declaration

cs-api-definition

protected string ComposeVisualStateName()

Returns

string

ComposeVisualStateNameBase()

Builds the current visual state for this instance.

Declaration

cs-api-definition

protected string ComposeVisualStateNameBase()

Returns

string

OnApplyTemplate()

When overridden in a derived class, is invoked whenever application code or internal processes (such as a rebuilding layout pass) call .

Declaration

cs-api-definition

public override void OnApplyTemplate()

OnInitialized(EventArgs)

Raises the event. This method is invoked whenever is set to true internally.

Declaration

cs-api-definition

protected override void OnInitialized(EventArgs e)

Parameters

EventArgs

The RoutedEventArgs that contains the event data.

OnTemplateApplied()

Occurs when the method has been called and the template is already successfully applied.

Declaration

cs-api-definition

protected void OnTemplateApplied()

ResetTheme()

Resets the theme.

Declaration

cs-api-definition

public void ResetTheme()

SetVisualState(string, bool)

Applies the specified visual state as current.

Declaration

cs-api-definition

protected virtual void SetVisualState(string state, bool animate)

Parameters

state

string

The new visual state.

animate

bool

True to use transitions, false otherwise.

UpdateVisualState(bool)

Re-evaluates the current visual state for the control and updates it if necessary.

Declaration

cs-api-definition

protected virtual void UpdateVisualState(bool animate)
