Event Data

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

Property	Description
Element	Gets the value that specifies the grid element with which a user interacts.
FieldName	Gets the field name of the column.
Item	Gets an object that specifies a data source’s item to which the grid’s data row corresponds.
RowHandle	Gets the grid’s row handle. Inherited from RowEventArgs.

Remarks

The DataGridView raises the following events in response to user gestures:

Gesture

Event

| | --- | --- | |

Tap

Tap and TapConfirmed

| |

Double Tap

Tap and DoubleTap

| |

LongPress

LongPress

The event parameter’s Element property allows you to obtain the element that was tapped.

If a user interacts with a data row, the Item property returns the data source’s item object that corresponds to the row. To obtain the tapped row handle, use the RowHandle property. If a user taps a data row that is not selected, the DataGridView.SelectionChanged event is also raised.

Example

This example shows how to set up the grid to display the Edit Values form when a user taps a cell. The grid is bound to a collection of orders.

Subscribe to the DataGridView.Tap event.
In the event handler:
In the App.xaml.cs file, assign a NavigationPage instance to the Application.MainPage property and add the MainPage content page to the navigation stack (the application’s root page):

The grid now displays the Edit Values form when a user taps a data cell.
