Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v24.2.dll

NuGet Package: DevExpress.Blazor

Declaration

C#

[Parameter]
public bool AllowUserInput { get; set; }

Property Value

Type	Description
Boolean	true to allow users to enter new values in the edit box; false to allow users to only select values from the drop-down window.

Remarks

Set the AllowUserInput property to true to allow users to type custom values into the edit box of the ribbon combo box item. The item does not add these values to the bound data source or a drop-down window. If a user enters a value equal to a drop-down window item, the editor selects the corresponding item.
