5 Jun 2020 / 3 minutes to read

SfRangeSlider provides option to show or hide the label and position customization.

Show Value Label

This property allows us to display labels for the ticks. When it sets to true, it displays the label for all the ticks based on the ValuePlacement property.

NOTE

The default value of the ShowValueLabel property is false.

c#

rangeSlider.ShowValueLabel= true;

Set Custom Label

To display custom labels, ShowCustomLabel property should be set to true and need to populate the CustomLabels property with observable collection of items by specifying the custom labels for corresponding values.

c#

SfRangeSlider rangeSlider; 
	 public RangeSliderPage ()
     {
           NSMutableArray<SfLabelItems> labels = new NSMutableArray<SfLabelItems>();
		   labels.Add(new SfLabelItems() { Label = (NSString)"Min", Value = 0 });
		   labels.Add(new SfLabelItems() { Label = (NSString)"Max", Value = 100 });
		   rangeSlider = new SfRangeSlider();
           rangeSlider.HeightRequest = 400;
           rangeSlider.ShowCustomLabel = true;
           rangeSlider.CustomLabel = labels;

	 }

Value Placement

The ValuePlacement property describes the position of the Value respective to ticks.

Available options for this property are:

• BottomRight

• TopLeft

c#

rangeSlider.ValuePlacement = SFValuePlacement.SFValuePlacementTopLeft;

c#

rangeSlider.ValuePlacement = SFValuePlacement.SFValuePlacementBottomRight;

Label Placement

The LabelPlacement property describes the position of the labels respective to ticks.

Available options for this property are:

• BottomRight

• TopLeft

c#

rangeSlider.LabelPlacement = SFLabelPlacement.SFLabelPlacementTopLeft;

Customizing label font

The range slider control provides the Font property to customize the value text and custom label text.

c#

SfRangeSlider sfRangeSlider = new SfRangeSlider();
	sfRangeSlider.Frame = new CoreGraphics.CGRect(10, 50, 350, 300);
	sfRangeSlider.FontSize = 22;
	sfRangeSlider.Font = UIFont.FromName("Helvetica", sfRangeSlider.FontSize);
	NSMutableArray<SfLabelItems> labels = new NSMutableArray<SfLabelItems>();
	labels.Add(new SfLabelItems() { Label = (NSString)"Min", Value = 0 });
	labels.Add(new SfLabelItems() { Label = (NSString)"Max", Value = 100 });
	sfRangeSlider.CustomLabel = labels;
	sfRangeSlider.TickPlacement = SFTickPlacement.SFTickPlacementBottomRight;
	sfRangeSlider.ShowCustomLabel = true;
	this.View.AddSubview(sfRangeSlider);

Customizing label color

The LabelColor property used to change the color of the label.

c#

rangeSlider.Labelcolor = Color.Red;
