Remarks

The <DxButtonGroup> component supports item selection. Use the SelectionMode property to specify the selection mode. The default mode is None – users cannot select button group items.

Set the SelectionMode property to Single or Multiple to enable single or multiple item selection. To select specific items in code, set their DxButtonGroupItem.Selected properties to true. To respond to property changes, handle corresponding DxButtonGroupItem.SelectedChanged events.

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

<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;
    }
}
