JavaScript Grid - beforeSetRange Event

pro version only

This functionality requires PRO version of the DHTMLX Grid (or DHTMLX Suite) package.

fires before setting a new range

beforeSetRange: (
    range: {
        xStart: string | number;
        xEnd: string | number;
        yStart: string | number;
        yEnd: string | number;
    }
) => boolean | void;

The callback of the event is called with the following parameters:

• xStart - (string | number) the starting column id
• xEnd - (string | number) the ending column id
• yStart - (string | number) the starting row id
• yEnd - (string | number) the ending row id

Return false to prevent setting a range; otherwise, true.

Example

const grid = new dhx.Grid("grid_container", {
    // other configuration
    rangeSelection: true
});

grid.range.events.on("beforeSetRange", (range) => {
    if (range.xStart === "b") {
        console.log("Range can't start with the column B");
        return false; // cancels setting a range
    }
});

grid.range.setRange({ xStart: "b", yStart: "1" }); // setting a new range is canceled
