Hi,

The RemovedItems items reflects the items removed from the selection, and not from the grid.

Handle the PreviewKeyDown event, and use the SelectedItems property to delete the selected rows there:

private void PreviewKeyDownHandler(object sender, KeyEventArgs e) {
var grid = (DataGrid)sender;
if ( Key.Delete == e.Key ) {
foreach (var row in grid.SelectedItems) {
... // perform linq stuff to delete here
}
}
}

try this and let me know

Hi,

In WPF there is a property "SelectedItem" for selecting a row and "Remove" function for deleting a row.

xamal code:
C#
<datagrid name="datagridTable" selecteditem="{Binding SelectedInformation}">
               ....
</datagrid>


ModalView:
C#
private Information selectedInformation;
public Information SelectedInformation
{
    get { return selectedInformation; }
    set { SetProperty(ref selectedInformation, value); }
}


public UserBase_ViewModal()
{
    delete = new DelegateCommand(DeleteInformationInTable);
}

private void DeleteInformationInTable()
{
   Information.Remove(SelectedInformation);
}

Have a look at this article:
WPF DataGrid Practical Examples[^]

A lot about WPF Datagrid and it's operations should be clear to you after this.
