HxButton #

Button (<button type="button">). See also Bootstrap Buttons.

Basic usage #

<HxButton Text="Basic Button" Color="ThemeColor.Primary" />

Several predefined button styles are included, each serving its own semantic purpose, with a few extras thrown in for more control.

Outline buttons #

You can remove the background with Outline="true":

Sizes #

<HxButton Text="Large" Size="ButtonSize.Large" Color="ThemeColor.Primary" />
<HxButton Text="Large" Size="ButtonSize.Large" Color="ThemeColor.Primary" />
<HxButton Text="Small" Size="ButtonSize.Small" Color="ThemeColor.Primary" />
<HxButton Text="Small" Size="ButtonSize.Small" Color="ThemeColor.Primary" />

Icons #

You can add an icon to the button by using the Icon parameter. The position of the icon can be changed with IconPlacement.

Spinners #

Button will show a spinner whenever the OnClick handler returns an incomplete awaitable Task.

<HxButton Text="Button with a Spinner" Size="ButtonSize.Regular" Color="ThemeColor.Primary" OnClick="async () => await Task.Delay(2000)" />

OnValidClick with spinner #

Manual spinner #

Spinner & Single click protection #

Button with a badge #

<HxButton Color="ThemeColor.Primary">
    Send all <span class="badge bg-secondary">15</span>
</HxButton>

Button with a tooltip #

You can use the Tooltip parameter to set the button's tooltip:

<HxButton Text="Button with a tooltip"
          Icon="BootstrapIcon.ClockHistory"
          Tooltip="This is a tooltip with a very, very long text. Is this tooltip text length enough? No. So let's make it even longer. And is the tooltip text long enough now? OK..."
          Color="ThemeColor.Secondary" />

Tooltip, wrapper, and CSS classes #

<div class="d-flex">
	<HxButton Text="Button with a tooltip"
			  Icon="BootstrapIcon.ClockHistory"
			  Color="ThemeColor.Secondary"
			  Tooltip="This is a tooltip with .text-uppercase."
			  TooltipCssClass="text-uppercase"
			  TooltipWrapperCssClass="ms-auto" />
</div>
