Grid
Methods for the Grid returned by the GridControl.getGrid method: getRows, getSelectedRows, and getTotalRecordCount.

GridRow
The getData method for the GridRow returned by the Grid.getRows and Grid.getSelectedRows methods.

GridRowData
The getEntity method for the GridRowData returned by the GridRow.getData method.

GridEntity
Methods for the GridEntity returned by the GridRowData.getEntity method: getEntityName, getEntityReference, getId, and getPrimaryAttributeValue.

ViewSelector
Methods for the ViewSelector returned by the GridControl.getViewSelector, getCurrentView, isVisible and setCurrentView

Before Kemas Kini CRM Online 2015 1 the only unique method for the subgrid control was refresh. When you know the name of the subgrid control you can access it using the following code, for example, to access the CONTACTS subgrid in the default account form.

  return false;
 }
})

See Collections (client-side reference) for information on the methods available to access data in a collection.

getSelectedRows

Returns a collection of every selected GridRow in the Grid.

//Get an array of entity references for all selected rows in the subgrid
var selectedEntityReferences = [];
var selectedRows = Xrm.Page.getControl("Contacts").getGrid().getSelectedRows();
selectedRows.forEach(function (selectedRow, i) {
 selectedEntityReferences.push(selectedRow.getData().getEntity().getEntityReference());
