多层网格层次结构-祖父母数据

Question

At the transaction level of the hierarchy, I need access to a value from the #grid data. Can this be passed as a parameter or must I traverse the DOM using jQuery?

$(document).ready(function () {
    var element = $("#grid").kendoGrid({
        ...
        detailInit: summary
    });
});

function summary(e) {
    $("<div/>").appendTo(e.detailCell).kendoGrid({
        ...
        detailInit: transactions
    });
}

function tranasctions(e) {
    $("<div/>").appendTo(e.detailCell).kendoGrid({
        ...
    });
}

Answer 1

AFAIK, the detailInit event only provides masterRow property in its first argument object, which stands for the parent expanded row. So I'm afraid you'll have to traverse it. What I suggest is to store the masterRow in a data attribute in the second detail grid in order to find it in the last level:

Second level grid:

$(e.detailCell).kendoGrid({
    // settings ...
}).data("master", e.masterRow);

This will create a data attribute named "master" with the first expanded row. Then in the third level you can retrieve it with:

var root = $(e.masterRow).closest(".k-detail-cell").data("master");
