  I have this code
  
  some class constructor…
  
  this.ObservableArray = new wijmo.collections.ObservableArray();
  
  this.DataMap = new wijmo.grid.DataMap(this.ObservableArray);

  I have a column in a flexgrid that has a drop down from this data map.
  
  At some point the observable array might be updated from an ajax call.
  
  I want to update the drop down in the flexgrid column

  Hi,

  If you need the DataMap to update automatically, then instead of storing simple string values in ObservableArray, you need to store them as Object and pass selectedValue and display path to the DataMap constructor. Please refer to the following code snippet and the sample demonstrating the same:

  var observableArr = new wjCore.ObservableArray(
    "US,Germany,UK,Japan,Italy,Greece".split(",").map((item) => ({ value: item }))
  );
  
  var countryCol = grid.columns.getColumn("country");
  countryCol.dataMap = new wjGrid.DataMap(observableArr, "value", "value");
