Customizing Cell Templates in Angular UI-Grid Based on Conditions

I am struggling to display a button in my ui-grid only when the field value is not an empty string. I attempted using the ng-if directive, but it is not functioning as expected. Below is the snippet from my grid options:

  { field: 'ReleaseStatus', 
    width: 125, 
    displayName: 'Release Status', 
    cellTemplate: 
    '<div ng-if="row.entity.ReleaseStatus != """>
        <button id="editBtn" 
            type="button" 
            class="btn btn-default"  
            data-toggle="modal" 
            data-target="#myModal" 
            ng-click="grid.appScope.launch(row)">
            {{COL_FIELD}}
        </button>
    </div>'
   },

Although the button works fine without ng-if, I need it to be hidden when the ReleaseStatus field is an empty string. Any help on this issue would be highly appreciated.

Answer №1

It is advisable to format it in the following manner: 

'<div ng-if="row.entity.ReleaseStatus !== \'\'">'

Alternatively, you may apply the ng-if directly to the element you wish to conceal.

Though, exercise caution while using ng-if as it generates a new scope each time.

Answer №2

Method 1: Here is a straightforward approach to achieve this task, take a look at the provided example.

{
    name: 'nameishere', displayName: 'Display Name', cellTemplate:
       '<div class="ui-grid-cell-contents" ng-if="grid.appScope.haveFile(row.entity.nameishere)"><a href="' + apiURL + '/InvalidFiles/{{row.entity.nameishere}}" download="{{row.entity.nameishere}}" >{{ row.entity.nameishere}}</a></div>'+
       '<div class="ui-grid-cell-contents" ng-if="grid.appScope.haveNotFile(row.entity.nameishere)">{{ row.entity.nameishere}}</div>'
},

and you can implement multiple functions OR utilize a function with if-else conditions

$scope.haveFile    = function (data) { return data == 'No File to Display' };
$scope.haveNotFile = function (data) { return data != 'No File to Display' };

Method 2: It is recommended to handle string and integer differently in this situation.

cellTemplate:'<div ng-if="row.entity.status !== \'Your String Here\'">'
cellTemplate:'<div ng-if="row.entity.status  !== 23>'

Method 3: Utilize ng-if in the following manner

cellTemplate:'<div>{{row.entity.status  == 0 ? "Active" : (row.entity.status  == 1 ? "Non Active" : "Deleted")}}</div>';
