Security is applied to the controls to ensure that the data is seen by authorized individuals within an organization. Permissions are based on the process rights assigned to the process in Management Console:

• Users with Admin or View permissions will have access to the Report controls.
• Users with View Participate permissions will be permitted to view the Report controls from the point where the user has been part of the workflow.

1. Create a View
2. Drag the Activity Instances Grid control onto the canvas. The control can be found in the Reports section of the Controls found in the View Designer, see the Properties section below 
3. Configure the properties of the Activity Instances Grid control as required, see the Properties section below 
4. Add a rule to Run the Grid when the View is Initialized for example:
   Event: When a control on the View raises an event (When the View is Initialized)
   Action: Execute a control's method (Execute the Run Grid method)
   

• Always remember to create a rule to Run the Grid when the View Initializes
• The value of the Activity Instances Grid is the selected instance id. When clicking on a record in the Activity Instances Grid in runtime, the value of the Grid will be the selected instance id and can subsequently be used to bind properties or configure rules
• When using Custom Themes, be sure to specify the CSS classes for the elements
• Grid control columns are predefined and can't be changed. However, columns can be deselected in the properties section of the control so that they are not displayed in runtime, if required
• The data of K2 workflows or processes created by any workflow designer such as K2 Studio, K2 Designer for Visual Studio, K2 Designer and K2 Designer for SharePoint  can be made available using the reporting controls 

Report controls interact with each other through rules. By binding properties between different controls, data can be used to populate properties or set values in runtime.

• The column properties displayed on the design canvas are available in the Context Browser for mapping to other controls. This means that the property can be dragged from the control to another control’s properties or control value
  
• The following properties are available as Input Mapping properties and in the Context Browser when using rules for mapping to other controls. These properties are additional to those mentioned in the Properties section of this topic, but are only available for interaction with rules:
  Activity Name - Filters the Grid based on the full Activity Name (including Folder and Process Name)
  Workflow Instance ID- Filters the Grid based on a Workflow Instance ID
  
• If I want to see the User Performance Grid for a specific client event for a specific workflow instance for example, the following rules will apply:
  Event: When the View executes a method
  Action: Execute a control's method
  Action: Execute a control's method
  Action: Execute a control's method
  
  
  Event: When a control on the View raises an event
  Action: Execute a control's method
  Configuration: Map the Workflow Instances Grid to the Workflow Instance id of the Activity Instances Grid
  
  
  Event: When a control on the View raises an event
  Action: Execute a control's method
  Configuration: Map the Workflow Instances Grid to the Workflow Instance ID of the of the User Performance Grid and the Full Activity Name of the Activity Instances Grid to the Activity Name of the User Performance Grid 
  
  
  When clicking on an activity on the Workflow Instances Grid at runtime, the Activity Instances Grid will reflect only activities for that specific workflow instance. In turn when clicking on a filtered activity on the Activity Instances Grid, the User Performance Grid will only reflect users who have completed that specific activity of the workflow instance

The Activity Instances Grid control is available in the Reports section of the Controls found in the View Designer.
