Hi there! In the code below when i reach $("#bans-grid").kendoGrid() function i get the type of error i've mentioned in the title. I don't understand why. Any help will be appreciated!


 $("#saveButton").kendoButton({
              click: function() {

                  var channelsData = $("#bans-grid").data().kendoGrid.dataSource.view();
                  var channelsDataJson = JSON.stringify(channelsData);

                      $("#bans-grid").kendoGrid({
                          dataSource: {
                                 transport: {
                                     update: {
                                         data: channelsDataJson,
                                         url: "/bg/NotosPrime/Bans/BanChannels",
                                         type: "PUT"
                                       }
                                     },
                                     schema: {
                                         model: {
                                             id: "Id"
                                         }
                                     }
                                }
                             });
                             $("#bans-grid").dataSource.sync();
                }

Hi Mihail,

In the shared code there are two lines on which the Grid should throw errors. 

The first line is this one:

var channelsData = $("#bans-grid").data().kendoGrid.dataSource.view();

The above should be changed to this one:

var channelsData = $("#bans-grid").data("kendoGrid").dataSource.view();

The next line you can update is this one:

$("#bans-grid").dataSource.sync();

The above should be changed to:

$("#bans-grid").data("kendoGrid").dataSource.sync();

Here is a Dojo example demonstrating the usage of the first change suggested above. 

I hope the above details will help you achieve what you need in your application.
