DxGridDataColumn.FilterBuilderFieldDisplayMode Property

Specifies whether the built-in filter builder displays a field for this column.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v25.2.dll

Declaration

[DefaultValue(GridColumnFilterBuilderFieldDisplayMode.Auto)]
[Parameter]
public GridColumnFilterBuilderFieldDisplayMode FilterBuilderFieldDisplayMode { get; set; }

Property Value

Type	Default	Description
GridColumnFilterBuilderFieldDisplayMode	Auto	An enumeration value.

Available values:

Name	Description
Never	The filter field is always hidden.
Always	The filter field is always visible.
Auto	The filter field’s visibility depends on the corresponding column’s visibility.

Remarks

The built-in filter builder dialog generates and configures filter fields based on Grid columns.

Read Tutorial: Filter Panel and Filter Builder Run Demo: Filter Builder Customization

The Grid sets field initial visibility based on the corresponding column’s visibility. The filter builder dialog automatically updates field visibility once a user displays or hides a column. To display or hide a field permanently, set FilterBuilderFieldDisplayMode to Never/Always.

The following code snippet hides the Order Date filter field:
