Angular Grid Ag-grid columnDefs动态变化 [英] Angular Grid ag-grid columnDefs Dynamically change

问题描述

我对动态更改 columnDefs 有问题。这是我的gridOptions：

I have a problem about columnDefs change dynamically. Here is my gridOptions:

$scope.gridOptions = {
        columnDefs: [],
        enableFilter: true,
        rowData: null,
        rowSelection: 'multiple',
        rowDeselection: true
    };

，当我从服务器检索数据时：

and when I retrive data from server:

$scope.customColumns = [];

$http.post('/Home/GetProducts', { tableName: 'TABLE_PRODUCT' }).success(function (data) {
    angular.forEach(data.Columns, function (c) {
        $scope.customColumns.push(
            {
                headerName: c.Name,
                field: c.Value,
                width: c.Width
            }
        );
    });

    $scope.gridOptions.columnDefs = $scope.customColumns;

    $scope.gridOptions.rowData = data.Products;
    $scope.gridOptions.api.onNewRows();
}).error(function () {

});

注意：这里c是来自服务器的列对象。

动态生成列并将其分配给$ scope.gridOptions.columnDefs时，会出现空白网格，但 $ scope.customColumns 数组用正确生成的列对象填充。请帮助我解决这个错误，或者我做错什么了？

When dynamically generating columns and assigning it to $scope.gridOptions.columnDefs there is blank grid but $scope.customColumns array is filled with right generated column objects. Please help me is this bug or I am doing something wrong?

推荐答案

在ag-grid中，gridOptions中的列在网格初始化。如果在初始化后更改列，则必须告知网格。通过调用 gridOptions.api.setColumnDefs（）

In ag-grid the columns in gridOptions are used once at grid initialisation. If you change the columns after initialisation, you must tell the grid. This is done by calling gridOptions.api.setColumnDefs()

此api方法的详细信息在< a href = http://www.ag-grid.com/angular-grid-api/index.php rel = noreferrer> ag-grid文档在这里。

Details of this api method are provided in the ag-grid documentation here.
