It extends the standard WPF button with rich icon support (SmallIcon, LargeIcon, IconTemplate), predefined size modes, toggle/checkable behavior, multiline text, MVVM command binding, corner radius, and full theme support via SfSkinManager.

Quick Start

Minimal XAML Setup

<Window xmlns:syncfusion="http://schemas.syncfusion.com/wpf" ...>
    <Grid>
        <syncfusion:ButtonAdv Label="Log in"
                              SizeMode="Normal"
                              SmallIcon="Images/user.png"

    </Grid>
</Window>

Minimal C# Setup

using Syncfusion.Windows.Tools.Controls;

ButtonAdv button = new ButtonAdv();
button.Label = "Log in";
button.SizeMode = SizeMode.Normal;
button.SmallIcon = new BitmapImage(new Uri("Images/user.png", UriKind.RelativeOrAbsolute));
Root.Children.Add(button);

Common Patterns

Button with Large Icon

<syncfusion:ButtonAdv Label="Save"
                      SizeMode="Large"
                      LargeIcon="Images/save-large.png"
                      Width="68" Height="68"/>

Toggle Button

<syncfusion:ButtonAdv Label="Bold"
                      SizeMode="Normal"
                      SmallIcon="Images/bold.png"
                      IsCheckable="True"
                      IsChecked="False"
                      Checked="OnBoldChecked"
                      Unchecked="OnBoldUnchecked"/>

MVVM Command Binding

<syncfusion:ButtonAdv Label="Submit"
                      SizeMode="Normal"
                      Command="{Binding SubmitCommand}"
                      CommandParameter="SubmitAction"/>

Icon Template (Vector/Font Icon)

<syncfusion:ButtonAdv Label="User" SizeMode="Normal">
    <syncfusion:ButtonAdv.IconTemplate>
        <DataTemplate>
            <Grid Width="16" Height="16">
                <Path Data="M16,0 C19.6,0 22.5,2.9 22.5,6.5 ..."
                      Fill="#FF3A3A38" Stretch="Fill"/>
            </Grid>
        </DataTemplate>
    </syncfusion:ButtonAdv.IconTemplate>
</syncfusion:ButtonAdv>
