ProjectDocument.getSelectedResourceAsync method

Asynchronously gets the GUID of the selected resource in a resource view.

Hosts: Project
Available in Requirement set Selection
Added in 1.0
Office.context.document.getSelectedResourceAsync([options,] [callback]);


Name Type Description Support notes
options object Specifies any of the following optional parameters.
asyncContext array, boolean, null, number, object, string, or undefined A user-defined item of any type that is returned in the AsyncResult object without being altered.
callback object A function that is invoked when the callback returns, whose only parameter is of type AsyncResult.

Callback Value

When the callback function executes, it receives an AsyncResult object that you can access from the parameter in the callback function.

For the getSelectedResourceAsync method, the returned AsyncResult object contains the following properties.

Name Description
asyncContext The data passed in the optional asyncContext parameter, if the parameter was used.
error Information about the error, if the status property equals failed.
status The succeeded or failed status of the asynchronous call.
value The GUID of the selected resource as a string.


The GUID of a resource is more useful in Project add-ins than the resource name. The resource GUID can be used to access resource information, such as data about resources in Project Online that is available through the client object model (CSOM). You can also save the resource GUID in a local variable and use it for the getResourceFieldAsync method.

If the active view is not a resource view (for example a Resource Usage or Resource Sheet view), or if no resource is selected in a resource view, getSelectedResourceAsync returns a 5001 error (Internal Error). See addHandlerAsync method for an example that uses the ViewSelectionChanged event and the getSelectedViewAsync method to activate a button based on the active view type.


The following code example calls getSelectedResourceAsync to get the GUID of the resource that's currently selected in a resource view. Then it gets three resource field values by calling getResourceFieldAsync recursively.

The example assumes your add-in has a reference to the jQuery library and that the following page controls are defined in the content div in the page body.

<input id="get-info" type="button" value="Get info" /><br />
<span id="message"></span>
(function () {
    "use strict";

    // The initialize function must be run each time a new page is loaded.
    Office.initialize = function (reason) {
        $(document).ready(function () {

            // After the DOM is loaded, add-in-specific code can run.

    // Get the GUID of the resource and then get the resource fields.
    function getResourceInfo() {
            function (data) {

    // Get the GUID of the selected resource.
    function getResourceGuid() {
        var defer = $.Deferred();
            function (result) {
                if (result.status === Office.AsyncResultStatus.Failed) {
                else {
        return defer.promise();

    // Get the specified fields for the selected resource.
    function getResourceFields(resourceGuid) {
        var targetFields =
            [Office.ProjectResourceFields.Name, Office.ProjectResourceFields.Units, Office.ProjectResourceFields.BaseCalendar];
        var fieldValues = ['Name: ', 'Units: ', 'Base calendar: '];
        var index = 0; 

        // Get each field, and then display the field values in the add-in.
        function getField() {
            if (index == targetFields.length) {
                var output = '';
                for (var i = 0; i < fieldValues.length; i++) {
                    output += fieldValues[i] + '<br />';

            // If the call is successful, get the field value and then get the next field.
            else {
                    function (result) {
                        if (result.status === Office.AsyncResultStatus.Succeeded) {
                            fieldValues[index] += result.value.fieldValue;
                        else {

    function onError(error) {
        $('#message').html( + ' ' + error.code + ': ' + error.message);
