Workflow Instances 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 ID - Filters the grid based on a Workflow Instance ID
  
• You can configure a rule to use one grid control to populate another grid control, for example when you click a workflow in a Workflow Instances Grid, an Activity Instances Grid is populated. To do this, configure the following rule:
  
  Map the Workflow Instances Grid to the Workflow Instance ID property of the Activity Instances 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.
• When [control] is ViewFlow-Clicked: You can execute a rule condition or action when the View Flow icon of the control is clicked, for example 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 instances.

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 control is also available when designing forms
• The value of the grid is the selected instance. When you click a record in the grid in runtime, the value of the grid is the instance you select 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.
