Collections (client-side reference)

  • Artykuł

 

Applies To: Dynamics CRM 2015

Collections are structures to provide access to data that represents an array, but without the ability to modify the data in the array.

The following list shows the collections that are available in the Xrm.Page object model:

  • Xrm.Page.data.entity.attributes: All the attributes on the page.

  • Xrm.Page.ui.controls: All the controls on the page.

  • Xrm.Page.ui.tabs: All the tabs on the page.

  • Xrm.Page.ui Tab.sections: All the sections in the tab.

  • Xrm.Page.ui Section.controls: All the controls in the section.

  • Xrm.Page.ui.navigation.items: All the items in the form navigation area.

  • Xrm.Page.ui.formSelector.items: All the forms available to the user.

  • Xrm.Page Attribute.controls: All the controls for the attribute.

  • Xrm.Page.data.process.getActivePath: The stages in the current active path based on branching rules.

  • The process getStages method for a process returned by Xrm.Page.data.process.getActiveProcess.

  • The stage getSteps method for stages returned by Xrm.Page.data.process.getActiveStage, Xrm.Page.data.process.getActivePath and Xrm.Page.data.process.getActiveProcess.

Note

The objects returned in the Xrm.Page.data.process namespace don’t contain names, so using the string parameter for the get method returns no objects.

With Microsoft Dynamics CRM Online 2015 Update 1, the getRows and getSelectedRows return collections of GridRow. More information: Grid objects and methods (client-side reference)
