Assembly: DevExpress.ExpressApp.v23.2.dll
NuGet Package: DevExpress.ExpressApp
Declaration
Remarks
An ImageInfo instance is an image used in an XAF application. Its properties provide access to the image and associated metadata, such as image dimensions and name.
XAF uses the ImageLoader class to manage images. To get an ImageInfo instance, use the ImageLoader.Get...ImageInfo methods. The following code snippet demonstrates how to use the ImageInfo.Image property to retrieve the specified image:
using DevExpress.ExpressApp;
using DevExpress.ExpressApp.Actions;
using DevExpress.ExpressApp.Utils;
using DevExpress.Persistent.Base;
namespace dxTestSolution.Module.Controllers {
public class CustomBlazorController : ViewController {
public CustomBlazorController() {
var _actionName = "MyAction1";
myAction = new SimpleAction(this, _actionName, PredefinedCategory.Edit);
myAction.Caption = _actionName;
myAction.ToolTip = myAction.Caption;
}
SimpleAction myAction;
protected override void OnFrameAssigned() {
base.OnFrameAssigned();
string imageName = $"action_export_tortf";
var imageInfo = ImageLoader.Instance.GetImageInfo(imageName);
if (!imageInfo.IsEmpty) {
myAction.ImageName = imageName;
myAction.Execute += (s, e) => { /*Add your custome code here*/ };
}
}
}
}
