Binding model to a grid and posting back selection

user1267983 Published in 2017-12-07 22:13:50Z

I'm attempting to bind a model to a grid and get back selections. I'm able to pass the model in and display the data I expect along with checkboxes for the selection. However when I try to pass the model back to the controller I just seem to get back the same model initially passed into the view without any selection changes.


@model ExViewModel

.Columns(columns =>
    columns.Bound(c => c.IsChecked).ClientTemplate("<input type='checkbox' #= IsChecked ? checked='checked':'' # class='chkbx' />" + "<input type='hidden' name='id' value='#= IsChecked#' />").Width(50);
    columns.Bound(c => c.Name).Width(175);
    columns.Bound(c => c.Details).Width(175);
.DataSource(dataSource => dataSource

@using (Html.BeginForm("CallNext", "Home", FormMethod.Post))
    <input hidden="hidden" id="model_output" name="model_output" value="@(Json.Encode(Model))" />
    <input id="btnSubmit" class="btn btn-primary" type="submit" value="Next >" />

    $(function () {
        $('#grid').on('click', '.chkbx', function () {
            var checked = $(this).is(':checked');
            var grid = $('#grid').data().kendoGrid;
            var dataItem = grid.dataItem($(this).closest('tr'));
            dataItem.set('IsChecked', checked);


public ActionResult CallNext(string model_output)
 . . . 

Using the above, the model_output I get back in the controller has all the default values for the IsChecked flag for Classes. I'm not sure what I'm overlooking - I've looked though a few examples online but I'm afraid I don't have much experience with Kendo, so I'm unsure as to what's going wrong. Any advice is greatly appreciated.

Can you confirm that the click handler is running ? I would presume yes.

The form posts the original model because the value="@(Json.Encode(Model))" is constructed at page render time not at page view runtime.

Try changing the submit button to perform a grid saveChanges


saveChanges calls the data source sync.

You could also use tool bars, they do even more of the plumbing for you. See the demos for more info.
