  I am using wijmo enterprise version with angular 7 and i come across a requirement in which i need to show a list of strings in filter popup from an external data source rather than the grid data on which search should also work. External data source is super set of grid data i.e. contains more data than grid e.g. grid data source has 50 rows and external source has more than 50 records. Although i have tried changing with unique values of filter but its not working.

  let columnFilter = this.filter.getColumnFilter(this.grid.columns[1]);
        columnFilter.valueFilter.uniqueValues = ['Alpena']
  

  Please share a stackblitz example or any sample to achieve that.

  Hi Rizwan,
  
  The code snippet shared by you is correct and it should work. But it depends, where the code is placed. We used the same code in the Filter initializing event. Please refer to the following stackblitz for the same:

  Hope it helps!
