DxGrid.ShowGroupedColumns Property

Specifies whether to display grouped columns with other columns in the grid’s data area.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v24.2.dll

NuGet Package: DevExpress.Blazor

#Declaration

C#
[DefaultValue(false)]
[Parameter]
public bool ShowGroupedColumns { get; set; }

#Property Value

Type Default Description
Boolean false

true to display grouped columns in the data area; otherwise, false.

#Remarks

When grid data is grouped, group rows display the values of grouped columns and the corresponding columns are hidden from the grid’s data area. This allows you to avoid displaying superfluous information.

To make grouped columns visible in the data area, set the ShowGroupedColumns property to true.
