 ## ToolTip Customization
 
-You can change the appearance of the ToolTip by customizing the style with TargetType as DataGridToolTipView.
+You can customize the appearance of the tooltip in the MAUI SfDataGrid using either implicit styles or default style properties. Below are two approaches to achieve this:
+
+### Apply Implicit Style
+
+You can define an implicit style in the ContentPage.Resources section by targeting the DataGridToolTipView. This allows you to customize various visual aspects of the tooltip such as Background, TextColor, FontAttributes, FontFamily, and FontSize. 
+
+To change the tooltip's border appearance, use the Stroke and StrokeThickness properties within the implicit style.
+
+* `Stroke`: Sets the border color of the tooltip.
+* `StrokeThickness`: Defines the thickness of the tooltip border.
