Hi 

I have problem binding DateTime field. I modified your example :https://demos.telerik.com/aspnet-mvc/spreadsheet/datasource

and added 

 [DataType(DataType.Date)]
        public DateTime TimeTest 
        {
            get;
            set;
        } = DateTime.Today;

to SpreadsheetProductViewModel.cs 

It displays the TimeTest field properly in excel sheet, but if I modify the date and submit the change, ModelState validation fails with following error:

The models contain invalid property values.The value 'Sat Jan 20 2018 00:09:00 GMT-0800 (Pacific Standard Time)' is not valid for TimeTest.

 

Please advice,

Thank you,

Hi Nareg,

The issue stems from the way data is sent to the server. So, the changes in the demo that should be made in order to work for dates are as follows:

function onSubmit(e) {
    $.ajax({
        type: "POST",
        url: '@Url.Action("Data_Source_Products_Submit", "Spreadsheet")',
        data: JSON.stringify(e.data),
        contentType: 'application/json; charset=utf-8',
        dataType: "json",
        success: function (result) {
            e.success(result.Updated, "update");
            e.success(result.Created, "create");
            e.success(result.Destroyed, "destroy");
        },
        error: function (xhr, httpStatusMessage, customErrorMessage) {
            alert(customErrorMessage);
        }
    });
}

public ActionResult Data_Source_Products_Submit([FromBody]SpreadsheetSubmitViewModel model)
{

 I hope this will fit to your scenario.

Regards,
Joana

No it didn't solve the issue. After this change SpreadsheetSubmitViewModel properties {Created, Destroyed, Updated} are getting set to null, regardless of rows added or updated. So making this change causes all bindings to fail.

sorry, it works, I forgot to add:

contentType: 'application/json; charset=utf-8',

Thank you,
