Class VisualStatesItemPresenter

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

Inheritance
System.Object
VisualStatesItemPresenter
Namespace: Telerik.Windows.Controls.RadialMenu
Assembly: Telerik.Windows.Controls.Navigation.dll

Syntax

public class VisualStatesItemPresenter : Control, IThemable

Constructors

VisualStatesItemPresenter()

Initializes a new instance of the VisualStatesItemPresenter class.

Declaration
public VisualStatesItemPresenter()

Fields

ArrowThicknessFactorProperty

Identifies the ArrowThicknessFactor dependency property.

Declaration
public static readonly DependencyProperty ArrowThicknessFactorProperty
Field Value
System.Windows.DependencyProperty

ThicknessFactorProperty

Identifies the ThicknessFactor dependency property.

Declaration
public static readonly DependencyProperty ThicknessFactorProperty
Field Value
System.Windows.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
public double ArrowThicknessFactor { get; set; }
Property Value
System.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.
Examples

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"

<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
protected bool IsTemplateApplied { get; }
Property Value
System.Boolean

ThicknessFactor

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

Declaration
public double ThicknessFactor { get; set; }
Property Value
System.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 OnApplyTemplate is called. Inheritors should override this method should they have some custom template-related logic. This is done to ensure that the IsTemplateApplied property is properly initialized.

Declaration
protected bool ApplyTemplateCore()
Returns
System.Boolean

CanUpdateVisualState()

Determines whether the current visual state may be updated.

Declaration
protected virtual bool CanUpdateVisualState()
Returns
System.Boolean

ComposeVisualStateName()

Builds the current visual state for this instance.

Declaration
protected string ComposeVisualStateName()
Returns
System.String

ComposeVisualStateNameBase()

Builds the current visual state for this instance.

Declaration
protected string ComposeVisualStateNameBase()
Returns
System.String

OnApplyTemplate()

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

Declaration
public override void OnApplyTemplate()

OnInitialized(EventArgs)

Raises the System.Windows.FrameworkElement.Initialized event. This method is invoked whenever System.Windows.FrameworkElement.IsInitialized is set to true internally.

Declaration
protected override void OnInitialized(EventArgs e)
Parameters
System.EventArgs e

The System.Windows.RoutedEventArgs that contains the event data.

OnTemplateApplied()

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

Declaration
protected void OnTemplateApplied()

ResetTheme()

Resets the theme.

Declaration
public void ResetTheme()

SetVisualState(String, Boolean)

Applies the specified visual state as current.

Declaration
protected virtual void SetVisualState(string state, bool animate)
Parameters
System.String state

The new visual state.
System.Boolean animate

True to use transitions, false otherwise.

UpdateVisualState(Boolean)

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

Declaration
protected virtual void UpdateVisualState(bool animate)
Parameters
System.Boolean animate

True to use transitions during state update, false otherwise.
