Angular JS UI-Grid Delete Row

Question

I'm new to ui-grid and I'm trying to implement a table in AngularJS as shown in the picture below. I'm trying to select a row and delete it using a delete button on that particular row. The ui-grid documentation requires us to use the gridApi but I can't find sufficient documentation for the same.

Answer 1

Please see a working example of how to delete a row here. http://plnkr.co/edit/6TiFC6plEMJMD4U6QmyS?p=preview

The key is to use indexOf(row.entity) and not relying on row.index as it doesn't dynamically get updated.

$scope.deleteRow = function(row) {
  var index = $scope.gridOptions.data.indexOf(row.entity);
  $scope.gridOptions.data.splice(index, 1);
};

Generic approach

function deleteRow(row,grid) {
   var i = grid.options.data.indexOf(row.entity);
   grid.options.data.splice(i, 1);
}

Might want to double check your example. Wasn't working for me today and is throwing a ton of errors. – Rufena

+1 for "row.index" and the details that row.identity doesn't dynamically updates. That was issue with my code and had banged my head already for a couple of hours. Thanks! – Tropism

A generic solution would be great, something like function (row,grid) { var i = grid(row.entity); grid.data.splice(i,1);}; – Popsicle

Answer 2

You can use @Blousie solution as far as you adapt it to the newer API: https://github.com/angular-ui/ng-grid/blob/master/3.0_UPGRADE.md

Now "grid.appScope.edit(row.entity)" gives you access to your scope's "edit" function.

Something like this:

var removeTemplate = '<button class="btn btn-danger" ng-click="grid.appScope.removeRow(row)"><i class="glyphicon glyphicon-remove"></i></button>';

$scope.removeRow = function(row) {
    var index = $scope.<yourDataModelProperty>.indexOf(row.entity);
    if (index !== -1) {
        $scope.<yourDataModelProperty>.splice(index, 1);
    }
};

We need to use the $scope.grid.appScope. It is available in all templates. Besides that, you need to send the row object from the template, so that you can delete the row from the grid data.

jsfiddle: http://jsfiddle.net/3ryLqa9e/4/

  cellTemplate:'<button class="btn primary" ng-click="grid.appScope.Delete(row)">Delete Me</button>' 

  $scope.Delete = function(row) {
            var index = $scope.gridOptions.data.indexOf(row.entity);
            $scope.gridOptions.data.splice(index, 1);
        };

Answer 4

The other solutions provided here didn't worked for me(May be because of my latest different version of ui-grid). So removing element from the scope array worked for me. This should even work with other versions of ui-grid because grid must be updated when the data changes. (Thanks to Angular!!!)

I am using lodash to remove element from array and here is sample code:

$scope.deleteRow = function(row){
    _.remove($scope.gridData, {
        id: row.id
    });
};

I went with this, but when using showGridFooter: true, the row is still counted in the "Selected Items: xxx" message in the table footer. – Alleluia

Answer 5

Just remove the row you want to delete from ui-grids data source model using splice.

For example

$scope.myGridOptions.data.splice(<YOUR ROW INDEX HERE>, 1);

After deleting one row, the index of the grid does not update with the index of the array. Therefore, I can't delete the rest of the rows. The refreshRows() method in ui-grid doesn't work as of now. – Elora

What are you using as index? – Constantine

Regarding ui-grid you should always mention the version you are working with. – Arhat

Figured it out, I am using version 3.0.0 $scope.deleteRow = function(row) { var index = $scope.items.indexOf(row.entity); $scope.items.splice(index, 1); }; – Elora
