How to open dialog container to preview image in React File Manager?

This article explains how to open dialog container with required aspect ratio to preview an image in React File Manager.

Step 1: Implement File Manager component using our getting started documentation.

Step 2: To achieve the dialog container being opened in the required aspect ratio for previewing images, you can utilize the help of the React File Manager popupOpen event. The popupOpen event triggers when the dialog popup is opened and allows you to adjust the height and width of the dialog container according to your requirements. This enables you to open the dialog container with the required aspect ratio to preview images. Additionally, we can also resize the dialog container to improve the better appearance of image preview.

[app.component.html]

<ejs-filemanager id='overview' height="700px" (popupOpen)="onPopupOpen($event)" [ajaxSettings]='ajaxSettings' [view]='view'>
</ejs-filemanager>

[app.component.ts]

public onPopupOpen (args: PopupOpenCloseEventArgs) {
    args.element.style.height = '600px';
    args.element.style.width = '600px';
}

[app.component.css]

.e-image-wrap {
    height: 100% !important;
    width: 100% !important;
}
