Question

I would like to handled SelectionChanged event in WPF DataGrid element for user interaction/selection only and skip if it’s due to binding or other set values. Any idea how I will determine if the Selection is changed by user interaction? Or any alternate event that would do similar task?

Maybe try combine SelectionChanged event with PreviewMouseDown event. When user click a row you set some property and in SelectionChanged event handler check if than property was changed.

Sample code XAML:

<DataGrid SelectionChanged="OnSelectionChanged" PreviewMouseDown="OnPreviewMouseDown">
        <!--some code-->          
</DataGrid>

Code behind:

bool isUserInteraction;

private void OnSelectionChanged(object sender, SelectionChangedEventArgs e)
{
    if (isUserInteraction)
    {
        //some code

        isUserInteraction = false;
    }
}

private void OnPreviewMouseDown(object sender, MouseButtonEventArgs e)
{
    isUserInteraction = true;
}
