Example

The following example shows how to create the Image dashboard item and provide a static image by URL. Create the ImageItem instance and use the ImageItem.urlPath property to specify a URL to a static image.

After you add the created dashboard item to the Dashboard.items collection, call the Dashboard.rebuildLayout method to rebuild the dashboard layout and display changes.

// Use the line below for a modular approach:
// import * as Model from 'devexpress-dashboard/model'
// Use the line below for an approach with global namespaces:
// var Model = DevExpress.Dashboard.Model;

public createImage(){
    var imageItem = new Model.ImageItem();
    imageItem.urlPath("https://www.devexpress.com/Products/NET/Dashboard/i/dashboard-tablet.png");
    imageItem.sizeMode("Squeeze");

    control.dashboard().items.push(imageItem);
    // ...
    control.dashboard().rebuildLayout();
}
