DXCollectionView.LongPress Event

Occurs when a user taps and holds an item within the collection view.

Namespace : DevExpress.Maui.CollectionView

Assembly : DevExpress.Maui.CollectionView.dll

NuGet Package : DevExpress.Maui.CollectionView

Declaration

csharp

public event EventHandler<CollectionViewGestureEventArgs> LongPress

Event Data

The LongPress event's data class is CollectionViewGestureEventArgs. The following properties provide information specific to this event:

Property	Description
Item	Gets an object that specifies a data source’s item to which the CollectionView’s data row corresponds.
ItemHandle	Gets the handle of the processed item. Inherited from ItemEventArgs.

Remarks

You can use two methods to identify the tapped item. The event argument’s Item property returns the item’s corresponding data source object. To receive the item’s handle, use the ItemHandle property.

Example

The following example deletes an item from the collection view and its bound data source when a user taps and holds the item:

XAML

xaml

<dxcv:DXCollectionView x:Name="collectionView"
                       LongPress="CollectionView_OnLongPress" >
</dxcv:DXCollectionView>

csharp

void CollectionView_OnLongPress(object sender, CollectionViewGestureEventArgs e) {
    collectionView.DeleteItem(e.ItemHandle);
}
