Formatting doesn't apply when manually setting data on grid

[Boris]

I have a Grid connected to DataSource and displayed on clipboard01.jpg
When I click on the Calculate button, I collect some the Grid's data and send it over to the server with an Ajax call
I return Json with some calculated values for the MTM field, which I'm adding to the grid...

    $.ajax({
        type: "POST",
        dataType: "json",
        data: unwindDataToPostObj,
        url: direction
    })
    .done(function (response) {
        var grid = $("#gridAssoc").data("kendoGrid");
        grid.dataSource.data(response);
        grid.refresh();
    })
    .fail(function (jqXHR) {
        console.log("error");
    });

Please look at picture: clipboard02.jpg now
The formatting for the Trade Date & Settle Date is now broken, although it was declarative set by the book.

    // ** Grid widget
    $("#gridAssoc").kendoGrid({
        dataSource: CFDUnwind._assocTradesDataSource,
        navigatable: true,
        selectable: "single",
        height: 300,
        resizable: true,
        sortable: {
            mode: "single",
            allowUnsort: false
        },
        columns: [
            { field: "Strategy", title: "Strategy", width: 60 },
            { field: "ImagineSNum", title: "ImagineSNum", width: 50 },
 
            {
                field: "TradeDate", title: "Trade Date", width: 48,
                template: '#= kendo.toString(TradeDate,"MM/dd/yyyy") #'
            },
            {
                field: "SetlDate", title: "Settle Date", width: 48,
                template: '#= kendo.toString(SetlDate,"MM/dd/yyyy") #'
            },

...etc....

1. Why is the formatting not obeyed?
2. In other words how do I manually set the data on the grid and preserve any formatting already set on the columns?

Did you resolve the date issue after setting the grid datasource in the client?  I'm having the same issue.  Thanks!

[Boris]

Brannon,

Yes, I resolved it with a hack :(
I ended up creating a new DTO on the server, and a brand new JSON response based on it,
where I have already formatted the dates and treated them as strings...

It did the job perfectly, but I don't like it...

Thanks,  I did the exact same thing.  I don't like it either, but it works for now.

Well...Cheers! :)
