-This article explains How to change the Xamarin.Forms numeric textbox style using its visual states
+
+This article explains how to customize the Syncfusion Xamarin.Forms numeric text box control using visual states.
+
+Let’s have a use case to keep default styles with having different background color which is varying based on its visual states if then Xamarin.Forms numeric text box control allows to do that with the help of global styles in Xamarin.Forms as per in below code snippet.
+
+[App.xaml]
+
+```
+   …    
+
+<Application.Resources>
+        <ResourceDictionary>
+            <Style x:Key="NumericTextBoxStyle" TargetType="numeric:SfNumericTextBox">
+                <Setter Property="VisualStateManager.VisualStateGroups">
+                    <VisualStateGroupList>
+                        <VisualStateGroup x:Name="CommonStates">
+                            <VisualState x:Name="Normal">
+                                <VisualState.Setters>
+                                    <Setter Property="BackgroundColor" Value="White" />
+                                </VisualState.Setters>
+                            </VisualState>
+                            <VisualState x:Name="Disabled">
+                                <VisualState.Setters>
