GridPanel - Set Selection if DataRow Value Matches Specific Field/Column in grid/store?

[Tbaseflug]

Based upon the results of a datatable - I am trying to set the selection of a gridpanel - works great if the value in row[0] is equal to the store reader id - but in this case - in place of the below - is there a way that I can take a value from the datatable and match it to a specific field in the store/gridpanel - in this case, I have a field called AccountNumber - so if the returned row from the datatable matches field AccountNumber - then select...?

  foreach (DataRow row in dt.Rows) // Loop over the rows.
                {
                    sm4.SelectedRows.Add(new SelectedRow(row[0].ToString()));
                }

So - In a simplified model of the dataset - in place of "ID" - I want to set selection based upon "Test"

    protected void LoadData()
    {
        Store store = this.GridPanel1.GetStore();
        store.DataSource = new object[] 
            { 
                new SomeClass()
                {
                    ID = "id1",
                    Test = "test1" 
                },
                new SomeClass()
                {
                    ID = "id2",
                    Test = "test2" 
                },
                new SomeClass()
                {
                    ID = "id3",
                    Test = "test3" 
                }
            };
        store.DataBind();
    }
