Example

// The example shows removing the last action from the history after modifying a value
const grid = new dhx.Grid("grid_container", {
    columns: [
        { id: "name", header: [{ text: "Name" }] },
        { id: "value", header: [{ text: "Value" }] },
    ],
    data: [
        { id: "1", name: "Item 1", value: 10 },
    ],
    history: true
});

// modifying a value via DataCollection
const updatedItem = { id: "1", name: "Updated Item", value: 15 };
grid.data.update("1", updatedItem);

// adding the action to history
grid.history.add({
    type: "change",
    batch: [{ ...updatedItem }],
    inverse: { type: "change", batch: [{ id: "1", name: "Item 1", value: 10 }] },
});

// removing the last action
grid.history.remove();
console.log(grid.history.getHistory().length); // -> 0
