Hi,

I am trying to enable inline editing for the KendoUI grid with an autocomplete control. I want to be able to post the edited model data into a controller action, however my parametermap code never gets executed. Can someone please explain what causes the parametermap code to get executed?

Here is my dataSource declaration:
var battingDataSource = new kendo.data.DataSource({
    schema: {
        model: {
            id: "PlayerId",
            fields: {
                PlayerId: { editable: false, nullable: true },
                PlayerFullName: { validation: { required: true } },
                BattingOrder: { type: "number", validation: { required: true, min: 1, max: 11 } },
                RunsScored: { type: "number", validation: { required: true, min: 0 } },
                BallsFaced: { type: "number", validation: { required: true, min: 0 } },
                Fours: { type: "number", validation: { required: true, min: 0 } },
                Sixes: { type: "number", validation: { required: true, min: 0 } },
            }
        }
    },
    batch: true,
    transport: {
        create: {
            url: "/MatchPlayer/Create",
            type: "POST"
        },
        update: {
            url: "/MatchPlayer/Update",
            type: "POST"
        },
        read: {
            url: "/MatchPlayer/Read",
            type: "POST"
        },
    },
    parameterMap: function (data, operation) {
        alert("hit");
        if (operation != "read") {
            // post the players so the ASP.NET DefaultModelBinder will understand them:
 
            var result = {};
 
            for (var i = 0; i < data.models.length; i++) {
                var player = data.models[i];
 
                for (var member in player) {
                    result["players[" + i + "]." + member] = player[member];
                }
            }
 
            return result;
        }
    }
});

Hello,

There is syntax mistake in the provided code - parameterMap function should be nested in transport object. Please correct it.
transport: {
    create: {
        url: "/MatchPlayer/Create",
        type: "POST"
    },
    update: {
        url: "/MatchPlayer/Update",
        type: "POST"
    },
    read: {
        url: "/MatchPlayer/Read",
        type: "POST"
    },
    parameterMap: function(data, operation) { /* your code */ }
},
