Add Event handlers after Batch Edit, Save Changes

Hi Team,

I would like to request the functionality to set the dataSource.model.id with a function handler rather than just a string. 

The usefulness behind this in my case is the mixing of dataTypes in the Kendo UI PanelBar. We are trying to mix the data in the results returned and do not currently have a common structure/object representing the data.

Thank you!

Hi Team,

I would like to request a way to use the Kendo UI DataSource with a flag set to state that it is returning a singular record.  For my case, my dataSource is using OData V4, and it requires utilizing an Ajax request to retrieve an individual entity. 

DataSource

      var dataSource = new kendo.data.DataSource({
        type: "odata-v4",
        transport: {
          read: function(options) {
            $.ajax({
              //makes a request for an individual entity by ID
              url: "https://demos.telerik.com/kendo-ui/service-v4/odata/Products(1)",
              //....
          }
        },
        //....
      });

It would be nice if there was a better way to do this.

Thank you!

Hi
I was just wondering if there was a message bus /Broadcast Channel component that was part of kendoUI.

I am thinking you could use your Observables or or something like the MVVM tooling.

just that the mozilla example does not work, it may be way out of date

thanks in advance

I selected the grid widget for this ticket, but the question is for all widgets with a remote filter service. I'm not finding a way to configure the DataSource to send the field data types, as defined in the schema, along with the filter request. The filter request array includes the field name, field value and ignore case values. It needs to also include the field data type, from the perspective of the DataSource. 

I know that I can parse values on the server side to try to guess the data type, as with the example applications, but that's not reliable in all cases, and I don't want to do that. It's better to know the field type based on the perspective of the widget.

Hopefully I'm just missing the DataSource configuration option to 'Include Field Data Types in Filtering Requests'. If that doesn't exist, please add it as an enhancement request, and let me know the most effective way to accomplish this that will work for all widget and data source combinations. I figured out that I can do this with a grid:

parameterMap: function (data, type) {
var fields = $("#grid").data("kendoGrid").dataSource.options.schema.model.fields;
var types = {};
for (let key in fields) {
types[key] = fields[key].type;
}
return $.extend({types}, data);
}

But I also have a Kendo Form with a form field edit of type MultiColumnComboBox, and the same approach will probably work, but I have to figure out how to get at the schema configuration in that case, and probably other combinations in the future.

See DoJo

This calls the DataSource read() method 10 times, but after 10 seconds only 2 of them are resolved (and actually only 2 requests are recorded in dev tools).

This is really annoying when relying on logic in a .then() block, because it is never called in the remaining cases.
