Condition Algorithm

A control needs to be uniquely identified by specifying some property condition to distinguish it from other controls. This topic describes the groupings that help specify the condition.

Conditions to uniquely identify the controls

  • NoCondition: NoCondition should be given to specify the first element of the tree.

  • PropertyCondition: It specifies the actual property and the expected value. The following is an example.

    <PropertyCondition Name="ControlType">ControlType.Pane</PropertyCondition>  
    
    

    This condition specifies that ControlType should be "ControlType.Pane".

  • AndCondition:

    • This groups the property conditions and results in TruePositive if all the property conditions are satisfied.

    • A minimum of two conditions must be given inside an AndCondition group. The following is an example.

      <AndCondition Id="SearchCondition">  
      <PropertyCondition Name="Name">System and Security</PropertyCondition>  
      <PropertyCondition Name="ControlType">Hyperlink</PropertyCondition>  
      </AndCondition>  
      
      

      This condition specifies that both the ControlType and Name properties need to be satisfied. The Name and the Value can be determined from the UISpy details of the control.

  • OrCondition:

    • This groups the property conditions and results in TruePositive if any one of the property conditions is satisfied.

    • A minimum of two conditions should be given inside the OrCondition group. The following is an example.

      <OrCondition Id="SearchCondition">  
      <PropertyCondition Name="Name">System and Security</PropertyCondition>  
      <PropertyCondition Name="ControlType">Hyperlink</PropertyCondition>  
      </OrCondition>    
      

      This condition specifies that either ControlType or Name property needs to be satisfied. The Name and the Value can be determined from the UISpy details of the control.

  • NotCondition:

    • This groups the property conditions and results in TruePositive if the property conditions are not satisfied.

    • Only one condition can be given inside a NotCondition group. The following is an example.

      <NotCondition Id="SearchCondition">  
      <PropertyCondition Name="Name">System and Security</PropertyCondition>  
      </NotCondition>  
      
      

      This condition specifies if the Name property condition is not satisfied. The Name and the Value can be determined from the UISpy details of the control.

  • NestedCondition:

    • The nested grouping must be specified, such as an OrCondition in an AndCondition. The final child condition should be a PropertyCondition.

    • Any property of following type can be included in the condition:

      • System.Boolean

      • System.String

      • System.Windows.Rect

      • System.Windows.Point

      • System.Windows.Automation.OrientationType

      • System.Windows.Automation.ControlType
