How to clear selection in a button click using MVVM in Xamarin DataGrid?
Xamarin.Forms DataGrid allows you clear the selection programmatically in two ways either by changing the SelectionMode to “None” or by using the SelectionController.ClearSelection method. You can clear the selection in a button click in MVVM by adding command and command parameter to the button.
Refer the below code example in which a Command is triggered for clearing the selection in SfDataGrid. The reference of SfDataGrid is passed as a CommandParameter to a button in order to clear the selection in the view model.
<Button Text="Clear Selection"
Command="{Binding ClearSelection}"
CommandParameter="{x:Reference dataGrid}" />
//ViewModel
clearSelection = new Command(ClearSelectionCommand);
private void ClearSelectionCommand(object obj)
{
var dataGrid = obj as SfDataGrid;
//Approach – 1:
//Clear selection using selection mode
dataGrid.SelectionMode = SelectionMode.None;
//Approach – 2:
//Clear selection using selection controller
dataGrid.SelectionController.ClearSelection();
}
private Command clearSelection;
public Command ClearSelection
{
get
{
return clearSelection;
}
}
