Workflow References Grid Control

1. Create a view.
2. Drag the control onto the canvas. You can find the control in the Reports section of the Toolbox.
3. Configure the properties of the control to display the data you want in the grid.
4. Run the view.

You can find the control in the Reports section of the Toolbox.

Report controls interact with each other through rules. When you bind properties between different controls, you can use the data to populate properties or set values. See the following points for using rules with control properties:

• When you use rules, you can use the control properties in the context browser for mapping to other controls. This means that you can drag the property from the control to another control’s properties or control value.
  
• You can use the following property as an input mapping property and in the context browser when you use rules for mapping to other controls. This property is additional to those mentioned in the Properties section of this topic, but is only available for interaction with rules:
  Workflow Instance - Filters the grid based on a Workflow Instance ID or gets a Workflow Instance ID value of a row you click
  
• When you configure the properties of the grid it is important to note the Value 1, Value 2 and Value 3 properties under the Data section. These properties are populated with the values of the required properties stored as part of the item references. The values are dynamic per item reference and are allocated in the order created. The first required property is linked to Value 1 and so forth.
  
• You can configure a rule to open the grid when you click a record in a Workflow Instances Grid. To do this, configure the following rule:
  
  Configuration: Map the Workflow Instances Grid to the Workflow Instance ID property of the Workflow References Grid
  

The following events and methods are available on the control:
Rule Events:

• When [control] is Changed: This event executes when the control is set to a new value that is different from the previous value. You can use this event to trigger actions when the control is changed, for example execute the Run method.
• When [control] is Populated: This event executes each time the control is loaded. You can execute a rule condition or action when the control is loaded, for example execute the Run method of another report control.
• When [control] is Clicked: You can execute a rule condition or action when the control is clicked, for example populate another control.
• When [control] is Double-Clicked: You can execute a rule condition or action when the control is double-clicked, for example populate another control or open a subview.

Control Methods:

• Execute a control's Clear method: Clears the workflow data from the control. You can use this method to, for example, clear the workflow data and then execute a Run method using rule mappings of a different workflow.
• Execute a control's Run method: Gets the data from the database, applies configuration and rule settings, and then displays detailed information of all Workflow Item References per workflow instance.

Security on the Report controls ensures that the data is seen by only those who are authorized. Permissions are based on the process rights assigned to the process in Management Site:

• Admin or View permissions: You can access the Report controls.
• View Participate permissions: You can view the Report controls from the point where you are part of the workflow.

• The value of the Activity Instances Grid is the instance id. When you click a record in the Activity Instances Grid at runtime, the value of the grid is the selected instance id which you can use to bind properties or configure rules.
• When you use custom themes, be sure to specify the CSS classes for the elements.
• You cannot change the predefined grid control columns. However, you can deselect columns in the control's properties so that they do not display.
• You can use Report controls to access the data of workflows created in any workflow designer, including the K2 Designer and K2 Designer for SharePoint.
