DataGridView.PullToRefreshCommand Property

Gets or sets the command executed when a user pulls the grid down to request content update.

Namespace: DevExpress.XamarinForms.DataGrid

Assembly: DevExpress.XamarinForms.Grid.dll


public ICommand PullToRefreshCommand { get; set; }

Property Value

Type Description

A command that exposes the ICommand interface.


You can configure the DataGridView so that it updates its content when a user pulls down from the top of grid rows.

Pull To Refresh

To enable this functionality, set the IsPullToRefreshEnabled property to true. Then, either define a refresh command in a view model and bind it to the PullToRefreshCommand property, or handle the PullToRefresh event.


This example shows how to set up the grid so that it allows users to request a content update with the pull-down gesture. To do this, follow the steps below.

  1. Set the DataGridView.IsPullToRefreshEnabled property to true to enable the grid’s pull-to-refresh functionality.
  2. Create a command to be executed when a user pulls the grid down. Set the DataGridView.IsRefreshing property to false after data is refreshed to hide the refresh indicator in the grid.

  3. Bind the DataGridView.PullToRefreshCommand property to the created command.
