+# How to work with Prism using the EventToCommandBehavior in Xamarin.Forms ListView (SfListView)
+
+You can pass the default event argument as parameter when using [Prism](https://prismlibrary.com/docs/index.html) Framework EventToCommandBehavior in Xamarin.Forms [SfListView](https://help.syncfusion.com/xamarin/listview/overview).
+
+The prism [EventToCommandBehavior](https://prismlibrary.com/docs/xamarin-forms/behaviors/eventtocommandbehavior.html) will pass the parameter based on the [CommandParameter](https://prismlibrary.com/docs/xamarin-forms/behaviors/eventtocommandbehavior.html#commandparameter), [EventArgsParameterPath](https://prismlibrary.com/docs/xamarin-forms/behaviors/eventtocommandbehavior.html#eventargsparameterpath) and [EventArgsConverter](https://prismlibrary.com/docs/xamarin-forms/behaviors/eventtocommandbehavior.html#eventargsconverter). The parameter will be null in the [Command](https://docs.microsoft.com/en-us/xamarin/xamarin-forms/app-fundamentals/data-binding/commanding) execute method, if no value passed to these parameters.
+
+You can also refer the following article

+
+**XAML**
+
+Refer the Prism Framework **EventToCommandBehavior** for ListView. Use **EventArgsConverter** to pass the default EventArgs to the **Command**.
