TablePattern.RowOrColumnMajorProperty Field

Identifies the RowOrColumnMajor property.

Namespace:  System.Windows.Automation
Assembly:  UIAutomationClient (in UIAutomationClient.dll)

public static readonly AutomationProperty RowOrColumnMajorProperty

This identifier is used by UI Automation client applications. UI Automation providers should use the equivalent field in TablePatternIdentifiers.

In the following example, a root element is passed to a function that returns a collection of AutomationElement objects that are descendants of the root and satisfy a set of property conditions. This example retrieves the AutomationElements that support TablePattern and where the RowOrColumnMajorProperty is either Indeterminate or ColumnMajor.

///-------------------------------------------------------------------- 
/// <summary> 
/// Finds all automation elements that satisfy  
/// the specified condition(s). 
/// </summary> 
/// <param name="targetApp">
/// The automation element from which to start searching. 
/// </param> 
/// <returns> 
/// A collection of automation elements satisfying  
/// the specified condition(s). 
/// </returns> 
///-------------------------------------------------------------------- 
private AutomationElementCollection FindAutomationElement(
    AutomationElement targetApp)
{
    if (targetApp == null)
    {
        throw new ArgumentException("Root element cannot be null.");
    }

    PropertyCondition conditionSupportsTablePattern =
        new PropertyCondition(
        AutomationElement.IsTablePatternAvailableProperty, true);

    PropertyCondition conditionIndeterminateTraversal =
        new PropertyCondition(
        TablePattern.RowOrColumnMajorProperty,
        RowOrColumnMajor.Indeterminate);

    PropertyCondition conditionRowColumnTraversal =
        new PropertyCondition(
        TablePattern.RowOrColumnMajorProperty,
        RowOrColumnMajor.ColumnMajor);

    AndCondition conditionTable =
        new AndCondition(
        conditionSupportsTablePattern,
        new OrCondition(
        conditionIndeterminateTraversal,
        conditionRowColumnTraversal));

    return targetApp.FindAll(
        TreeScope.Descendants, conditionTable);
}
