  Hello,
  
  in angular 2, is there a way to set the inputElement of the inputDate component to readonly and therefore force the user to touch/click the calendar button to choose the date?

  Hi,

  You may handle the keydown event and call preventDefault() to disable input using input box.
  
  Please refer to the following code snippet and sample:

  let inp = inputDateInstance;
  inp.hostElement.addEventListener('keydown',(e)=>{
        switch(e.keyCode){
          case wjcCore.Key.F4: //allow open dropdown using f4
          case wjcCore.Key.Left: // allow selection using shift + left/right
          case wjcCore.Key.Right: return;
        }
        // disable otherwise
        e.preventDefault();
      }, true);

  Hi,
  
  in the end, we used the following solution:

  
  const inputDate: WjInputDate = this.elementRef.nativeElement['$WJ-CTRL'] as WjInputDate;
  inputDate.inputElement.disabled = true;
  
  

  I hope that can help other people
