Question

I have implemented a simple search function that highlights a row in a DataGrid based on a search query. The gist of it is shown below:

public bool scrollToSearch(string query) {
    dataGrid.SelectedItems.Clear();

    for (; searchIndex < registrants.Count; searchIndex++) {
        foreach (string field in registrants[searchIndex]) {
            if (field.ToLower().Contains(query)) {
                dataGrid.SelectedItem = registrants[searchIndex];
                dataGrid.ScrollIntoView(registrants[searchIndex]);
                searchIndex++;
                return true;
            }
        }
    }     
}       

It searches the list for a match, then highlights(selects) that row and scrolls it into view. The problem is that, when the DataGrid is sorted, the search will highlight a seemingly random row instead of the first result, because it is searching the original, unsorted list. Is there a way I can get at the sorted list to search it instead?

First do this….

var view = CollectionViewSource.GetDefaultView(registrants);

then use view in place of registrants in your code.
