ButtonGroup Selection
The ButtonGroup lets you select one or more of its ButtonGroupToggleButton instances depending on the SelectionMode setting:
You can control whether a button is selected (it is in its Primary state) through its Selected parameter. It offers two-way binding and an SelectedChanged event so you can respond to the user actions.
Single Selection
When you click a button, it becomes selected. When you click another button, the first one will become de-selected and the second one will be selected.

@* You can use more complex logic to show different components. To load data asynchronously, use the OnClick event or the OnParametersSetAsync event of a component you render *@
<TelerikButtonGroup SelectionMode="@ButtonGroupSelectionMode.Single">
<ButtonGroupToggleButton @bind-Selected="@FirstSelected">First</ButtonGroupToggleButton>
<ButtonGroupToggleButton @bind-Selected="@SecondSelected">Second</ButtonGroupToggleButton>
<ButtonGroupToggleButton @bind-Selected="@ThirdSelected">Third</ButtonGroupToggleButton>
</TelerikButtonGroup>
@if (FirstSelected)
{
<div class="alert alert-info">the first button is selected</div>
}
@if (SecondSelected)
{
<div class="text-danger">Second button is selected</div>
}
@if (ThirdSelected)
{
<div class="alert alert-success">third</div>
}
@code{
bool FirstSelected { get; set; }
bool SecondSelected { get; set; } = true; // you can pre-select buttons
bool ThirdSelected { get; set; }
}
Multiple Selection
When you click a button, it becomes selected. When you click another button, the first one retains its selected state, and the second one will also be selected. Clicking on a selected button will deselect it.
