Unbale to identity WinForm ListView subitems in Coded UI test VSTS 2010

This is my window application code for listview :-

// Create three items and three sets of subitems for each item.
        ListViewItem item1 = new ListViewItem("item1", 0);
        item1.SubItems.Add("1");
        item1.SubItems.Add("2");
        item1.SubItems.Add("3");
        ListViewItem item2 = new ListViewItem("item2", 1);
        item2.SubItems.Add("4");
        item2.SubItems.Add("5");
        item2.SubItems.Add("6");
        ListViewItem item3 = new ListViewItem("item3", 0);
        // Place a check mark next to the item.
        item3.Checked = true;
        item3.SubItems.Add("7");
        item3.SubItems.Add("8");
        item3.SubItems.Add("9");

        // Create columns for the items and subitems.
        // Width of -2 indicates auto-size.
        listView1.Columns.Add("Item Column", 100, HorizontalAlignment.Left);
        listView1.Columns.Add("Column 2", 100, HorizontalAlignment.Left);
        listView1.Columns.Add("Column 3", 100, HorizontalAlignment.Left);
        listView1.Columns.Add("Column 4", 100, HorizontalAlignment.Center);

        //Add the items to the ListView.
        listView1.Items.AddRange(new ListViewItem[] { item1, item2, item3 });

Then i add the lisview control in Coded UI test :-

In the coded UI test i used below code

WinList wkList = this.UIForm1Window.UIListView1Window.UIListView1List;

            string[] strVal = CommonExtensions.GetValuesOfControls(wkList.Items);

            foreach(WinControl control in this.UIForm1Window.UIListView1Window.UIListView1List.Items)
            {

                int count = control.GetChildren().Count;
                object objVal = CommonExtensions.GetValue(control);
                WinListItem lstItem = (WinListItem)objVal;
            }

in the "strVal " variable gives only values of first column not the subitems.

in add watch window i get below mentioned value:-

strVal[0] = "item1"
strVal[1] = "item2"
strVal[2] = "item3"

I have also used the http开发者_如何学JAVA://blogs.msdn.com/b/gautamg/archive/2010/02/19/useful-set-of-utility-functions-for-coded-ui-test.aspx?CommentPosted=true#commentmessage

WinListItem listItem = new WinListItem(control);
string[] strSubItems = WinExtensions.GetColumnValues(listItem);

In the above statement i am getting Invalid Io expection stating "The control passed is not a list view item control. This operation is valid only for list view item control."

Please suggest any other alternative ?.

I usually use smth like that:

WinList list;

UITestControlCollection columns = websitesList.Columns; // Get Columns names

// Get values
foreach (WinControl item in list.Items)
   {
        WinListItem listItem = new WinListItem(item);
        string[] subItems = WinExtensions.GetColumnValues(listItem); // So you get value = subitem[i] in column[i]
   }
