DxListEditorColumn.SearchEnabled Property

Specifies whether the component can search text in cells of the current column.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v25.1.dll

NuGet Package: DevExpress.Blazor

Declaration

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

Property Value

Type	Default	Description
Boolean	true	true if search in the current column is enabled; otherwise, false.

Remarks

The list editors (DxListBox<TData, TValue>, DxComboBox<TData, TValue>, and DxTagBox<TData, TValue> ) can search text in visible data column cells, and filter and highlight search results. Use the SearchEnabled property to exclude a specific column from search operations.

The following code snippet excludes the List Box’s second column from search.
