    I need to do some server side validation of data that is being updated on a large grid and wanted to give the user an idea of where any validation errors occurred in the grid.  Ideally it would be by highlighting the row/cell and having a mouse over or other error message associated. 

    What I have done so far is:
    Controller:
    ModelState.AddModelError(Item.Id, "this value is outside of the valid range");
    JavaScript grid error handler
    01.function error_handler(e) {
    02.    var data = e.sender._data;
    03.    if (e.errors) {
    04.        $.each(e.errors, function (key, value) {
    05.            highlightError(data, key, value);
    06.        });
    07.    }
    08.}
    09. 
    10.function highlightError(data, key, value) {
    11.    var grid = GetGrid("grid");
    12.    for (var i = 0; i < data.length; i++) {
    13.        var row = data[i];
    14. 
    15.        if (row.id == key) {
    16.            var hasError = $('[data-uid="' + row.uid + '"]');
    17.            hasError.addClass('kendo-error-row');  //this seems to be working, but it doesn't survive the whole process.
    18.            hasError[0].mouseover = function () { alert(errors[error].value); };
    19.        }
    20.    }
    21.}
    It seems like the code is working, but it doesn't seem to stick around until the end and if I use the IE developer tools it doesn't show the new class or have the mouseover.  What am I missing?

    Thanks!

    Hi Logan,

     
    Basically this feature is not supported out-of-the-box, however for convenience I created small project which demonstrates the required behavior and attached it to the current thread (please check this screencast). The packages are removed from the project in order to reduce it's size. 

    Kind Regards,
