How to remove wpf grid sort arrow after clearing sort descriptions

Question

I click on a grid header to sort a column and then click a "Reset" button to clear the sort descriptions through its collection view. But the sort arrow icon still persists in the header. How to remove it?

Answer 1

I came across this question whilst trying to work out how to clear the sort from the grid completely. Thanks to [krishnaaditya] for the answering how to clear the sort arrow from the header.

using System.Windows.Data;
using System.ComponentModel;

ICollectionView view = CollectionViewSource.GetDefaultView(resultsGrid.ItemsSource);
if (view != null && view.SortDescriptions.Count > 0)
{
    view.SortDescriptions.Clear();
    foreach (DataGridColumn column in resultsGrid.Columns)
    {
        column.SortDirection = null;
    }
}

Answer 2

simple solution i can think of is

foreach (DataGridColumn column in DataGridView.Columns)
{
    column.SortDirection = null;
}
