DxRangeSelector.SelectedRangeStartValue Property

Specifies the start value of the selected range.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v24.2.dll

NuGet Package: DevExpress.Blazor

Declaration

[Parameter]
public object SelectedRangeStartValue { get; set; }

Property Value

Type	Description
Object	The start value.

Remarks

The Range Selector allows you to select a range in code. To set a range, use one of the following options:

• Specify both SelectedRangeStartValue and SelectedRangeEndValue properties.
• Specify SelectedRangeLength and SelectedRangeStartValue / SelectedRangeEndValue properties.
• Specify the SelectedRangeLength property only. When you leave SelectedRangeStartValue and SelectedRangeEndValue properties unspecified, the Range Selector component uses the last scale value as the range’s end value.

When you leave the range unset, it matches the entire scale at the first component render.

Example

The following code snippets specify a predefined range on the first render. Switch code tabs to see possible options.
