Hello David.

It is much easier to iterate through all the rows by using the UIA patterns. The underlying UIA AutomationElement can be retrieved using the NativeElement property of the UITestControl.

The following sample code will use UIA patterns to iterate through all the rows, and extract the cell value for the first column into a list.

//==============================
// This sample code will extract all the values for the first column and put them into a list.
int rowIndex = 0;
List<string> cellValues = new List<string>();
System.Windows.Automation.AutomationElement containerAutomationElement = uIColScrollRegion0RowSTree.NativeElement as System.Windows.Automation.AutomationElement;
System.Windows.Automation.AutomationElement rowAutomationElement = null;
System.Windows.Automation.ItemContainerPattern containerPattern = containerAutomationElement.GetCurrentPattern(System.Windows.Automation.ItemContainerPattern.Pattern) as System.Windows.Automation.ItemContainerPattern;
rowAutomationElement = containerPattern.FindItemByProperty( null, System.Windows.Automation.AutomationElement.AutomationIdProperty, rowIndex.ToString());
while (rowAutomationElement != null)
{
// get the collection of cell automation elements
System.Windows.Automation.AutomationElementCollection cellsAutomationElements = rowAutomationElement.FindAll(System.Windows.Automation.TreeScope.Children, System.Windows.Automation.Condition.TrueCondition);

// get the automation element for the first cell
System.Windows.Automation.AutomationElement cellAutomationElement = cellsAutomationElements[0];

// Scroll the cell into view. This is necessary due to an existing bug which should be addressed shortly.
System.Windows.Automation.ScrollItemPattern scrollPattern = cellAutomationElement.GetCurrentPattern(System.Windows.Automation.ScrollItemPattern.Pattern) as System.Windows.Automation.ScrollItemPattern;
scrollPattern.ScrollIntoView();

// use the ValuePattern to get the Value.
System.Windows.Automation.ValuePattern valuePattern = cellAutomationElement.GetCurrentPattern(System.Windows.Automation.ValuePattern.Pattern) as System.Windows.Automation.ValuePattern;
cellValues.Add(valuePattern.Current.Value);

// get the next row
rowIndex++;
rowAutomationElement = containerPattern.FindItemByProperty(null, System.Windows.Automation.AutomationElement.AutomationIdProperty, rowIndex.ToString());
}

// do something with the list of cell values.
//==============================

Let us know if you need further assistance.

Using the CodedUI framework: Create a UITestControl for cell's editor, and call Mouse.Click() on the UITestControl. Note that in order to create a TestControl, you'd work your way down the hierarchy finding all the appropriate intermediate objects.

if (valuePattern.Current.Value == "KK")
{
UITestControl rowTestControl = new UITestControl(uIColScrollRegion0RowSTree);
rowTestControl.SearchProperties.Add(UltraUiaControl.PropertyNames.AutomationId, rowAutomationElement.Current.AutomationId);
rowTestControl.Find();

UITestControl cellTestControl = new UITestControl(rowTestControl);
cellTestControl.SearchProperties.Add(UltraUiaControl.PropertyNames.AutomationId, cellAutomationElement.Current.AutomationId);
cellTestControl.Find();

UITestControl dataAreaControl = new UITestControl(cellTestControl);
dataAreaControl.SearchProperties.Add(new PropertyBLOCKED EXPRESSION;

break;
}

Let me know how this turns out.

• Use the CodedUITestBuilder to record the item selection.
• Use UIA (more specifically, the SelectionItem Pattern which is available on the value list items).

If you want to discuss this UltraUiaComboBox further, please create new thread in this forum. I'd prefer not to piggyback this older Grid-CodedUI thread for a ComboEditor related issue.

Thanks,

Chris
