+## Populate ItemsSource
+
+Items can be added to the control using the [ItemsSource](https://help.syncfusion.com/cr/maui/Syncfusion.Maui.TabView.SfTabView.html#Syncfusion_Maui_TabView_SfTabView_ItemsSource) property of [SfTabView](https://help.syncfusion.com/cr/maui/Syncfusion.Maui.TabView.SfTabView.html).
+
+Objects of any class can be provided as items for `SfTabView` using `ItemsSource`. The views corresponding to the objects can be set using the [HeaderItemTemplate](https://help.syncfusion.com/cr/maui/Syncfusion.Maui.TabView.SfTabView.html#Syncfusion_Maui_TabView_SfTabView_HeaderItemTemplate) for the header items and [ContentItemTemplate](https://help.syncfusion.com/cr/maui/Syncfusion.Maui.TabView.SfTabView.html#Syncfusion_Maui_TabView_SfTabView_ContentItemTemplate) for the content.

+Create a **Model** class using the TabItems collection property, initialized with the required number of data objects, as shown in the following code examples.
