Question

I have a WPF DataGrid with a button on one of the columns.
When I click the button I have this function called:

MyClass mySC = (MyClass)(CollectionViewSource.GetDefaultView(grdMyClass.DataContext).CurrentItem);

This code works perfect, but when I click on the button on the new line (the last on on the grid) I get the msSC of the line before it, and not null, or something that related to the last new line.

how can I check if the button was clicked in the new line ?

Answer 1

If your intention is that clicking on a button should do something with the data bound to that row then just get the data from the button’s data context. If null then user clicked on an empty row.

private void Button_Click(object sender, RoutedEventArgs e)
{
    MyClass data = (sender as FrameworkElement).DataContext as MyClass;
}
