DxTreeListDataColumn.FilterRowEditorVisible Property

Specifies whether the column’s filter row cell displays the automatically generated editor.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v24.1.dll

NuGet Package: DevExpress.Blazor

Declaration

[DefaultValue(true)]
[Parameter]
public bool FilterRowEditorVisible { get; set; }

Property Value

Type	Default	Description
Boolean	true	true to display the filter row editor; otherwise, false.

Remarks

Enable the ShowFilterRow option to activate a row that allows users to filter TreeList data. The TreeList component generates and configures cell editors for filter row cells based on associated column data types. You can disable a column’s FilterRowEditorVisible property to hide this column’s editor and prevent users from filtering data by this column.

Note that the FilterRowEditorVisible property does not affect custom filter row editors defined in the FilterRowCellTemplate.

The following example hides the filter row editor in the Surface Gravity column:
