Vwa.VwaControl.getAllPageIds Method

apps for Office and SharePoint

Returns an array of strings that contains the names of all the pages contained within the Web Drawing.

var value = VwaControl.getAllPageIDs()

string[] An array of strings that contains the names of all the pages contained within the Web Drawing.

The getAllPageIds method does not return the names of background pages or hidden pages in the Web Drawing.

The page names returned are the same as those returned by the Page.Name property in Microsoft Visio 2013. They are not the same as those returned by the Page.NameU property.

For more information about how to add a Visio Web Access Web Part to a SharePoint Web Parts page, see Customizing Visio Web Drawings in the Visio Web Access Web Part.

The following example displays a custom HTML message in the Visio Web Access Web Part that lists each page in the Web Drawing.

<script type='text/javascript'>

// Add a button to display or dismiss the custom message.
document.write("<input type='button' value='Show Message' onclick='buildPageList()' />");

// Declare global variables.
var vwaControl;
var vwaPages;
var isPageSet;
 
// Hook into the AJAX Sys.Application.load event.
Sys.Application.add_load(onApplicationLoad)

// Capture a reference to the current session of the Visio Web Access Web Part.
function onApplicationLoad() {
    try{
        vwaControl= new Vwa.VwaControl(getVWAWebPartID());
        vwaControl.addHandler("diagramcomplete", onDiagramComplete);
    }
    catch(err){
        alert(err);
    }
}

    var divArray = document.getElementsByTagName("div");
