+## Mouse Wheel Support for Scrolling Tabs
+
+When the tab strip contains more tabs that can be displayed, enable mouse wheel scrolling to help navigate to tab headers that are not currently visible. Set the [IsMouseWheelScrollingEnabled](https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.Controls.SfTabControl.html#Syncfusion_Windows_Controls_SfTabControl_IsMouseWheelScrollingEnabled) property to `True` on the [SfTabControl](https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.Controls.SfTabControl.html).

+
+Mouse wheel scrolling moves the tab header strip horizontally, allowing users to quickly access tabs that are outside the currently visible area.

## Customizing the New Tab Button
You can customize the appearance of the new tab button using the [NewTabButtonStyle](https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.Controls.SfTabControl.html#Syncfusion_Windows_Controls_SfTabControl_NewTabButtonStyle) property. This allows you to modify visual properties such as background, border, width, and height.

+## Grouping Toast Notifications
+
+You can group related toast notifications by assigning the same value to the [GroupName](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.SfToastNotification.ToastOptions.html#Syncfusion_UI_Xaml_SfToastNotification_ToastOptions_GroupName) property in [ToastOptions](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.SfToastNotification.ToastOptions.html). Grouping helps organize related notifications and reduces clutter when multiple toasts are displayed.
+
+{% tabs %}
+{% highlight C# %}
+
+SfToastNotification.Show(this, new ToastOptions
+{
+ Mode = ToastMode.Window,
+ Title = "Application Status",
+ Header = "Review the latest application updates",
+ Message = "Message Area",
+ GroupName = "Reminders"
+});
+
+SfToastNotification.Show(this, new ToastOptions
+{
+ Mode = ToastMode.Window,
+ Title = "New Features",
+ Header = "New features are available to explore",
+ GroupName = "Reminders"
+});

+SfToastNotification.Show(this, new ToastOptions

+ Placement = ToastPlacement.BottomLeft,
+ Title = "General Updates",
+ Header = "Check out the detailed update notes",
+ GroupName = "Alerts"
+});
+
+{% endhighlight %}
+{% endtabs %}
+
+To display a toast in a different group, specify a different group name. Toasts without a `GroupName` value are not assigned to a custom group.
+
+
+
+## Custom Position
+
+The [ToastOptions](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.SfToastNotification.ToastOptions.html) class provides flexible toast positioning. Use the [Placement](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.SfToastNotification.ToastOptions.html#Syncfusion_UI_Xaml_SfToastNotification_ToastOptions_Placement) property with a built-in [ToastPlacement](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.SfToastNotification.ToastPlacement.html) value, and use `HorizontalOffset` and `VerticalOffset` to adjust the toast relative to that placement. To position a toast at exact coordinates, set `Placement` to `Custom` and specify the `X` and `Y` coordinates. Positive and negative offset values move the toast relative to its selected placement. When `Placement` is set to `Custom`, `X` and `Y` specify the toast position directly.
+
+{% tabs %}
+{% highlight C# %}
+
+// Apply offsets to a built-in placement.
+SfToastNotification.Show(this, new ToastOptions
+{
+ Mode = ToastMode.Screen,
+ Placement = ToastPlacement.BottomRight,
+ Title = "Offset Toast",
+ Message = "This toast is displayed with custom offsets.",
+ HorizontalOffset = -50.0,
+ VerticalOffset = 20.0
+});
+
+// Display a toast at an exact position.
+SfToastNotification.Show(this, new ToastOptions
+{
+ Mode = ToastMode.Window,
+ Placement = ToastPlacement.Custom,
+ Title = "Custom positioned toast",
+ Message = "This toast is displayed at the specified coordinates.",
+ X = 200,
+ Y = 450,
+ PreventAutoClose = true
+});
+
+{% endhighlight %}
+{% endtabs %}
+
+
+
+N> Absolute coordinates disable automatic stacking so each toast remains at its defined location. Offsets with predefined placements retain the normal stacking behavior.
+
+## Toast Distance Customization
+
+Use the [Spacing](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.SfToastNotification.SfToastNotification.html#Syncfusion_UI_Xaml_SfToastNotification_SfToastNotification_Spacing) property to customize the vertical distance between stacked toast notifications. The spacing value is applied globally to the toasts displayed by [SfToastNotification](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.SfToastNotification.SfToastNotification.html).
+
+{% tabs %}
+{% highlight XAML %}
+
+
+
+
+
+{% endhighlight %}
+
+{% highlight C# %}
+
+private void Button_Click(object sender, RoutedEventArgs e)
+{
+ SfToastNotification.Spacing = double.Parse(ToastSpacingTextBox.Text);
+
+ SfToastNotification.Show(this, new ToastOptions
+ {
+ Mode = ToastMode.Screen
+ });
+}
+
+{% endhighlight %}
+{% endtabs %}

## Action Buttons
You can add interactive action buttons to a toast notification by using the `Actions` collection. You can also use the [ShowActionButtons](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.SfToastNotification.ToastItem.html#Syncfusion_UI_Xaml_SfToastNotification_ToastItem_ShowActionButtons) property to control whether the action button row is displayed for in-app toast modes. The default value of `ShowActionButtons` is `true`.
