问题:

The data in my columns (provided by dropdown) and the filter of a column should match. So I use the same array to populate both. However for the data I can tell ui grid the field names to use for editDropdownValueLabel and editDropdownIdLabel. Is there such a thing for the filter property?

I ask because I'm setting the cell data dropdown values and the filter from an array retrieved from a web api call and my cell data dropdown is populated correctly but my filters all say 'undefined', which leads me to believe it doesn't know what field in the selectOptions array property to use.

When I define my grid I leave out the arrays for the cell and filter as I'll populate that when the web api call returns with that data.

{
    name: 'Status',
    field: 'Status',
    width: 200,
    editType: 'dropdown',
    editableCellTemplate: 'ui-grid/dropdownEditor',
    editDropdownIdLabel: 'Value',
    editDropdownValueLabel: 'Value',
    filter: {
        type: uiGridConstants.filter.SELECT,
        condition: uiGridConstants.filter.EXACT
    }
}

How I populate both the cell dropdown and filter dropdown from web api data.

$scope.gridStore.columnDefs[i].editDropdownOptionsArray = response.data[colFieldName];
$scope.gridStore.columnDefs[i].filter.selectOptions = response.data[colFieldName];

Without seeing more of your code it's hard to say exactly what's happening, but in the following example I add the Status column definition dynamically.

var app = angular.module('app', ['ngTouch', 'ui.grid', 'ui.grid.edit']);

app.controller('MainCtrl', ['$scope', 'uiGridConstants', function($scope, uiGridConstants) {

  $scope.myData = [{
    "Name": "Cox",
    "Number": 41,
    "Status": 1,
    "Date": "10/06/1981"
  }, {
    "Name": "Lorraine",
    "Number": 431,
    "Status": 2,
    "Date": "03/04/1983"
  }, {
    "Name": "Nancy",
    "Number": 341,
    "Status": 1,
    "Date": "10/06/1981"
  }];

  // grid setup
  $scope.gridStore = {
    data: $scope.myData,
    enableSorting: true,
    enableFiltering: true,
    flatEntityAccess: true,
    fastWatch: true,
    enableHorizontalScrollbar: 1,
    enableCellSelection: true,
    enableCellEditOnFocus: true,
    columnDefs: [{
        name: 'Number',
        field: 'Number',
        width: 100,
        pinnedLeft: true,
        enableCellEdit: false
      }, {
        name: 'Name',
        field: 'Name',
        width: 200,
        pinnedLeft: true,
        enableCellEdit: false
      }, {
        name: 'Date',
        field: 'Date',
        width: 100
      }
    ]
  };
  
  this.typeLookup = function (val, arr) {
    var result = arr.filter(function(v) {
        return v.id === val;
    })[0].type;

    return result;
  };


  /* simulate getting JSON settings data here ... */
  
  var jsonDef = { name: 'Status', field: 'Status', width: 150, editType: 'dropdown', editableCellTemplate: 'ui-grid/dropdownEditor', editDropdownIdLabel: 'id', editDropdownValueLabel: 'type', filter: { type: uiGridConstants.filter.SELECT, condition: uiGridConstants.filter.EXACT } };

  var options = [{
    id: 1,
    type: 'Closed'
  }, {
    id: 2,
    type: 'Pending'
  }, {
    id: 3,
    type: 'Open'
  }];

  $scope.gridStore.columnDefs.push(jsonDef);
  
  var idx = $scope.gridStore.columnDefs.length - 1;
  
  $scope.gridStore.columnDefs[idx].cellTemplate = '<div class="ui-grid-cell-contents">{{ grid.appScope.Main.typeLookup(COL_FIELD,' + JSON.stringify(options) + ') }}</div>';
  $scope.gridStore.columnDefs[idx].editDropdownOptionsArray = options;
  $scope.gridStore.columnDefs[idx].filter.selectOptions = options.map(function(obj) { 
    var rObj = {'value': obj.id, 'label': obj.type};
    return rObj;
  });
  
  /* end simulated JSON retrieval */

}]);

.grid {
  height: 200px;
}

A neat feature I use when dealing with dropdowns on ui grids is that I treat them like they're always dynamic so I no longer have to deal with OptionsArray, filters, labels and so on (which is a pain with dynamic data).

Just something to look into when you plan on expanding your knowledge in angular ui grid.

HTML:

<div ui-grid="gridOptions" ui-grid-edit class="grid"></div>

Controller:

$scope.gridOptions = {
    enableSorting: true,
    enableFiltering: true,
    enableCellEditOnFocus: true,
    columnDefs: [
      { field: 'name',
        sort: {
          direction: 'desc',
          priority: 1
        }
      },
      { field: 'gender', editType: 'dropdown', enableCellEdit: true,
          editableCellTemplate: 'temp.html' },
      { field: 'company', enableSorting: false }
]};

temp.html:

<div>
    <select ng-model="row.entity.gender" data-ng-options="d as d.type for d in genderType">
        <option value="" selected disabled>Choose Gender</option>
    </select>
</div>
