When editing a grid, how do I disable specific fields by row?

I have a kendo grid with data in it and multiple columns (say col 1, 2, and 3). Columns 1, 2, 3 need to be able to be edited (or preventing editing) based off the values of each other. This is row specific.

For instance, if column 1 (date) is < column 2 (date) then column 3 is not allowed to be edited.

I know it's simple enough to disable or enable an entire column but my requirements are row specific. So row 1 could have column 3 enabled and row 2 could have column 3 disabled.

Any thoughts?

Keep it simple just use (Which you bind in your grid column)

[Editable(false)]
public string ob_name { get; set; }

In your Costume class which using for your Kendo Ui Grid.

My suggestion is creating an editor function that validates the condition. This of course has the disadvantage that is an ad-hoc solution but ... it works!

Lets have the following entries (data of the DataSource):

var entries = [
    { id:1, col1: new Date(2012, 11, 31), col2: new Date(2013, 0, 1), col3: "Yes" },
    { id:2, col1: new Date(2013, 0, 1), col2: new Date(2013, 0, 1), col3: "No" },
    { id:3, col1: new Date(2013, 0, 2), col2: new Date(2013, 0, 1), col3: "No" }
];

Then I define the grid as:

var grid = $("#grid").kendoGrid({
    dataSource : {
        data    : entries,
        schema  : {
            model: {
                id    : "id",
                fields: {
                    col1: { type: "date"},
                    col2: { type: "date"},
                    col3: { editable: true }
                }
            }
        },
        pageSize: 3
    },
    columns    : [
        { field: "col1", title: "Col1", format: "{0:yyyy-MM-dd}" },
        { field: "col2", title: "Col2", format: "{0:yyyy-MM-dd}" },
        { field: "col3", title: "Edit?", editor: checkAndEdit }
    ],
    editable   : "incell",
    navigatable: true,
    pageable   : true
}).data("kendoGrid");

Where col1 and col2 are dates and col3 is a string that can be edited if and only if col1 is less than col2.

I define checkAndEdit function as follow:

function checkAndEdit(container, options) {
    if (options.model.col1 < options.model.col2) {
        $('<input data-bind="value:' + options.field + '" ' +
                'data-format="' + options.format + '" ' +
                'class="k-input k-textbox"/>')
                .appendTo(container);
    } else {
        grid.closeCell(container);
    }
}

Where I generate the corresponding input field if col1 < col2 and otherwise invoke closeCell for exiting edit mode.
