To reproduce:

1. Use the following code:
private void Form1_Load(object sender, EventArgs e)
{
    this.customersTableAdapter.Fill(this.nwindDataSet.Customers);

    this.radGridView1.DataSource = customersBindingSource;
    this.radGridView1.AutoSizeColumnsMode = Telerik.WinControls.UI.GridViewAutoSizeColumnsMode.Fill;
    this.radGridView1.CellEndEdit += radGridView1_CellEndEdit;
    this.radGridView1.AutoSizeRows = true;
    SortDescriptor descriptor = new SortDescriptor();
    descriptor.PropertyName = "Country"; 
    descriptor.Direction = ListSortDirection.Ascending;
    this.radGridView1.MasterTemplate.SortDescriptors.Add(descriptor);
}

void radGridView1_CellEndEdit(object sender, Telerik.WinControls.UI.GridViewCellEventArgs e)
{
    int selectedRowIndex = this.radGridView1.ChildRows.IndexOf(this.radGridView1.CurrentRow);
    this.radGridView1.TableElement.ScrollToRow(selectedRowIndex);
}

2. Modify cell value in the sorted column. After the editor value is confirmed by pressing Enter, you scroll to the current column. However, you do not observe the expected behavior.

Workaround: set the AutoSizeRows property to false.
