DxRibbonComboBoxItem<TData, TValue>.EditTextChanged Event

Fires when a user updates a text in the edit box of the Ribbon’s combo box.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v25.2.dll

NuGet Package: DevExpress.Blazor

Declaration

[DefaultValue(null)]
[Parameter]
public EventCallback<string> EditTextChanged { get; set; }

Parameters

Type	Description
String	The new text.

Remarks

Set AllowUserInput to true to allow users type custom values into the Ribbon’s combo box. The combo box fires the EditTextChanged event when a user does one of the following:

• Changes the text and removes focus from the combo box.
• Changes the text and presses Enter.
• Selects an item in the drop-down list.

Note

Typed values are not inserted into the bound data source or added to the drop-down list. If a user enters a value equal to an existing item, the combo box selects that item.

The following code snippet displays the value typed in the Ribbon’s combo box:
