We have analyzed the sample that you have provided. The cause of the issue is Dialog which is appended to the <body> tag. The content inside the “ng-scope” alone is replaced when we use partial view. Our EJ Dialog component will append to the <body> tag. To overcome this problem, use “e-content” property to render the Dialog within a container. Also the error “I is undefined” will be resolved if you use the ej.widget.angular.min.js file version 13.2.0.34.
