Question

I have a nested component with a dx-text-box. At a curtain time I want to know at the parent comonent if the text box is empty (value) or not. How can I check it? Frank

Answer 1

At the parent component ts I use

@ViewChild(MyChildComponent) myChildComponent: MyChildComponent;
...
if (this.myChildComponent.myValueFromTextBox == '') {...}
