Properties

IsCoercionSuppressed

Gets or sets a value that indicates whether the slider should coerce the setting of related properties like Value, SelectionStart, SelectionEnd, Minimum, Maximum, MinimumRangeSpan and MaximumRangeSpan.

Declaration

public bool IsCoercionSuppressed { get; set; }

Property Value

System.Boolean

Remarks

If set to True, the coercion is done only when the user manipulates the slider and not if the related properties are set by code or through binding.

IsInitializing

Gets or sets whether the control is initializing.

Declaration

protected bool IsInitializing { get; set; }

Property Value

System.Boolean

IsSelectionRangeEnabled

Gets or sets a value that indicates whether the RadSlider can displays a selection range. This is a dependency property.

Declaration

public bool IsSelectionRangeEnabled { get; set; }

Property Value

System.Boolean

Remarks

The SelectionStart and SelectionEnd properties define a selection range and must be set for the selection range to appear when IsSelectionRangeEnabled is set to true.

Examples

 <telerik:RadSlider   
        x:Name="radSlider1" 
        Width="100"
        IsSelectionRangeEnabled="True" />

 RadSlider radSlider1 = new RadSlider();
    radSlider1.Width = 100;     
    radSlider1.Orientation = Orientation.Horizontal;
    radSlider1.IsSelectionRangeEnabled = true;
    LayoutRoot.Children.Add(radSlider1);

IsUserManipulationInProgress

Gets or sets a value indicating whether this instance is user manipulation in progress.

Declaration

protected bool IsUserManipulationInProgress { get; set; }

Property Value

System.Boolean `True` if this instance is user manipulation in progress; otherwise, `false`.

MaximumRangeSpan

Gets or sets the maximum value distance between SelectionStart and SelectionEnd.

Declaration

public double MaximumRangeSpan { get; set; }

Property Value

System.Double

Remarks

The IsSelectionRangeEnabled property of RadSlider has to be set to True.

Examples

 <telerik:RadSlider   
        x:Name="radSlider1" 
        Width="100"
        IsSelectionRangeEnabled="True"
        MaximumRangeSpan="0.1"/>

 RadSlider radSlider1 = new RadSlider();
    radSlider1.Width = 100;     
    radSlider1.IsSelectionRangeEnabled = true;
    radSlider1.MaximumRangeSpan = 0.7;
    LayoutRoot.Children.Add(radSlider1);

MinimumRangeSpan

Gets or sets the minimum value distance between SelectionStart and SelectionEnd.

Declaration

public double MinimumRangeSpan { get; set; }

Property Value

System.Double

Remarks

The IsSelectionRangeEnabled property of RadSlider has to be set to True.

Examples

 <telerik:RadSlider   
        x:Name="radSlider1" 
        Width="100"
        IsSelectionRangeEnabled="True"
        MinimumRangeSpan="0.1"/>

 RadSlider radSlider1 = new RadSlider();
    radSlider1.Width = 100;     
    radSlider1.IsSelectionRangeEnabled = true;
    radSlider1.MinimumRangeSpan = 0.1;
    LayoutRoot.Children.Add(radSlider1);

Selection

Gets or sets the selection - SelectionStart and SelectionEnd.

Declaration

public SelectionRange<double> Selection { get; set; }

Property Value

SelectionRange<System.Double> The selection.

Implements

IRangeSelector<T>.Selection

SelectionEnd

Gets or sets the largest value of a specified selection.

Declaration

public double SelectionEnd { get; set; }

Property Value

System.Double

Implements

IRangeSelector<T>.SelectionEnd

Remarks

The value of the SelectionEnd property cannot be greater than the value of the System.Windows.Controls.Primitives.RangeBase.Maximum property and cannot be less than the value of the System.Windows.Controls.Primitives.RangeBase.Minimum property. The value of the SelectionEnd property must also be greater than or equal to the value of the SelectionStart property. If the value of the SelectionEnd property is greater than the value of the System.Windows.Controls.Primitives.RangeBase.Maximum property or less than the value of the System.Windows.Controls.Primitives.RangeBase.Minimum property, the value is set to the value of the System.Windows.Controls.Primitives.RangeBase.Maximum or System.Windows.Controls.Primitives.RangeBase.Minimum property respectively.

    radSlider1.IsSelectionRangeEnabled = true;
    radSlider1.SelectionEnd = 8;
    radSlider1.SelectionStart = 6;
    LayoutRoot.Children.Add(radSlider1);

SelectionRange
