NuGet Package: DevExpress.Blazor

#Declaration

C#
[DefaultValue(false)]
[Parameter]
public EventCallback<bool> SelectedChanged { get; set; }

#Parameters

A new Selected property value.

#Remarks

The <DxButtonGroup> component allows you to select and deselect button group items. Set the DxButtonGroup.SelectionMode property to Single or Multiple to enable selection.

Handle the SelectedChanged event to respond to the item’s Selected property change.

The following code snippet sets the component’s selection mode to Single and displays the current selection state of the Admin button group item:

Razor
<p>Is item selected - @IsItemSelected</p>

<DxButtonGroup RenderStyle="ButtonRenderStyle.Secondary"
               RenderStyleMode="ButtonRenderStyleMode.Outline"
               SelectionMode="ButtonGroupSelectionMode.Single">
    <Items>
        <DxButtonGroupItem Text="Admin"
                           Selected="@IsItemSelected"
                           SelectedChanged="@OnSelectedChanged"/>
        <DxButtonGroupItem Text="Editor" />
        <DxButtonGroupItem Text="Guest" />
    </Items>
</DxButtonGroup>

@code {
    bool IsItemSelected = false;

    void OnSelectedChanged(bool isSelected) {
        IsItemSelected = isSelected;
    }
}
