Create a Custom Command Column

In the following code, command-editing is a custom command column. It displays links that redirect a user to a separate page for editing. The column is configured using a cellTemplate. Note that it is an unbound column, that is, it does not have the dataField specified.

jQuery
JavaScript
$(function(){
    $("#dataGridContainer").dxDataGrid({
        dataSource: [{
            ID: 1,
            CompanyName: "Premier Buy",
            City: "Richfield",
            State: "Minnesota"
        },
        // ... 
        ],
        keyExpr: "ID",
        columns: [
            "CompanyName", "City", "State", 
            {
                name: "command-editing",
                allowFiltering: false,
                allowSorting: false,
                cellTemplate: function(cellElement, cellInfo) {
                    cellElement.append("<a href='./edit?id=" + cellInfo.data.ID + "'>Edit</a>");
                }
            }
        ]
    });

});
