Question

I have a UserControl, which is basically a wrapper for a GridView that needs to send a message every time a cell content (of the GridView) is changed. Usually, that could be solved like this:

private void MainDataGrid_CellEditEnding(object sender, DataGridCellEditEndingEventArgs e)
    {
        var editingTextBox = e.EditingElement as TextBox;
        doSomething(editingTextBox.Text);
    }

The problem is that I don’t know the type of EditingElement (which comes as a FrameworkElement) so I cannot do the conversion. And in that moment, the currentCell.SelectedValue is still the original value. I also don’t have control over the model (where I could implement INotifyPropertyChanged and use it to catch the changes).

Is there some simple way I am missing? Or how would you go about implementing this? Thank you for any suggestions.

I have found a very simple solution (can’t belive I haven’t seen that one) composed of catching two events from the DataGrid.
Here is the code:

private object changedRow;

    private void MainDataGrid_CellEditEnding(object sender, DataGridCellEditEndingEventArgs e)
    {
        changedRow = e.Row.Item;
    }

    private void MainDataGrid_CurrentCellChanged(object sender, EventArgs e)
    {
        if (changedRow != null)
        {
            // do something with the edited row here
            changedRow = null;
        }
    }
