DxSchedulerDayViewBase.CellMinWidth Property

Specifies the base width of a day cell in day, week, and work week views, in pixels.

Namespace: DevExpress.Blazor.Base

Assembly: DevExpress.Blazor.v24.1.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 day cell, in pixels.

Remarks

The CellMinWidth property specifies the base value used to calculate the minimum cell width of a cell in day, week, and workweek views: this property does not take cell borders and paddings, and time ruler into account.

The following code example sets the property value to 100:

Index.razor

@using Data

<DxScheduler StartDate="@DateTime.Today"
             DataStorage="@DataStorage">
    <DxSchedulerDayView ShowWorkTimeOnly="true"

                        CellMinWidth="100" />
</DxScheduler>

@code {
    DxSchedulerDataStorage DataStorage = new DxSchedulerDataStorage() {

To specify the minimum cell width for other views, use the following properties:

• DxSchedulerMonthView.CellMinWidth
• DxSchedulerTimelineView.CellMinWidth
