Live TextEntry value

Pretty basic question. If I have a TextEntry box I want to evaluate the value.  Something along the lines of

DLSYS.Read(Dsp.TextEntry1)

The  idea here is a popup form that you use TextEntry1 to type in the name of a module.. Then a script will take that text entry and open a corresponding faceplate.  

Thanks in advance

  You will have to have interaction logic on the TextEntry1 OnWrite and OnEnter interactions to update a variable to use and open the Faceplate Display.

  For Example (EnteredTag is a display variable of string type):

  TextEntry1.OnWrite(newValue: string): string
  {
  Dsp.EnteredTag = String(newValue);
  return Dsp.EnteredTag;
  }

  TextEntry1.OnEnter(): void
  {
  let TagOK = await DLSYS.ExistsAsync(Dsp.EnteredTag + "/BAD_ACTIVE.CV");
  if (TagOK == true) {
  //Find Position of TextEntry1 to Open FP near
  let region = DL.GetDisplayElementRegion(Dsp.TextEntry1);
  let pos = new Types.Placement({
      Option: Constants.PlacementOption.NearRegion,
      Region: region,
      UseCachedPosition: false
  });
      DL.OpenFaceplateAsync(Dsp.EnteredTag,[pos]);
  }
  else {
      //Tag entered doesn't exist
      DL.MessageBoxAsync('Tag ' + Dsp.EnteredTag + ' does not exist','Error', Constants.MessageBoxButtonType.MB_OK, 30 )
  }
  }
