The Blazor Range Selector component is an interface for selecting a small range from a larger collection. It is commonly used in financial dashboards to filter a date range for data that needs to be visualized.

Data types

Plot different types of data in the Blazor Range Selector component using different value types like numeric, date-time, and logarithmic.

Chart Types

Use the Blazor Range Selector component with different chart types like line, area and step line.


Skip the chart and show just the range to select data. This makes a range selector light weight in mobile devices.


A date-time axis can be configured to show in major and minor scales. The major and minor scales show where a range falls within different intervals and are displayed in multiple levels

Time Period Selector

Select data using predefined time periods in the range navigator and use the date picker to select a custom range.

Binding selected data

Bind selected data from a range selector to any other data visualization control using built-in events.

Deferred scrolling

The selected range doesn’t change until the user stops dragging the thumbs. This provides a smooth scrolling experience.

Range selection

The Blazor Range Selector component provides the following ways to select a range:

  • Select a range through labels.
  • Drag the left and right thumbs.
  • Drag the selected range to maintain the same delta.

Blazor Range Selector selection


All the elements of the Blazor Range Selector component are highly customizable with built-in APIs.

Blazor Range Selector labels


Customize the size, color, font family, font attribute, and alignment of the labels using built-in APIs.

Blazor Range Selector thumb
