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

SelectionEnd

Gets or sets the largest value of a specified selection.

Declaration
public double SelectionEnd { get; set; }
Property Value
System.Double

Implements
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.

Examples
 <telerik:RadSlider   
        x:Name="radSlider1"

    radSlider1.Width = 100;     
    radSlider1.Orientation = Orientation.Horizontal;
    radSlider1.Minimum = 0;
    radSlider1.Maximum = 10;
    radSlider1.TickPlacement = TickPlacement.TopLeft;
    radSlider1.TickFrequency = 1;
    radSlider1.IsSelectionRangeEnabled = true;
    radSlider1.SelectionEnd = 8;
    radSlider1.SelectionStart = 6;
    LayoutRoot.Children.Add(radSlider1);

SelectionRange

Gets the difference between SelectionStart and SelectionEnd.

Declaration

Property Value
System.Double

The difference between SelectionStart and SelectionEnd.

SelectionStart

Remarks

IsSelectionRangeEnabled must be True in order to use SelectionStart and SelectionEnd The value of the SelectionStart property cannot be less than the value of the Minimum property and cannot be greater than the value of the Maximum property. The value of the SelectionEnd property must also be greater than or equal to the value of the SelectionStart property. If SelectionStart is less than Minimum or greater than Maximum, SelectionStart is set to the value of Minimum or Maximum respectively.
