DxSchedulerTimelineView.CellMinWidth Property

Specifies the base width of a single division of the timescale, in pixels.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v25.2.dll

NuGet Package: DevExpress.Blazor

Declaration

[DefaultValue(180)]
[Parameter]
public int CellMinWidth { get; set; }

Property Value

Type	Default	Description
Int32	180	The minimum width of a single division of the scale, in pixels.

Remarks

When you define a scale for the Timeline view, the scheduler displays cells whose duration equals Unit * UnitCount. The CellMinWidth property specifies the base value used to calculate the minimum cell width: this property does not take cell borders, paddings, or time ruler into account.

You can use the VerticalResourceCellWidth propety to specify the resource cell width when resource captions are displayed horizontally.
