Whenever I hit the "create" action on a Kendo Grid, it runs the same server side call for every item in the list that I created.

For example, I have three columns Increment/Range/SetId.

I add one item: 1/1/1
This calls my CreateItem method for the 1/1/1 item.

I add a second item: 2/2/1
This calls my Create Item method for the 1/1/1 item and the 2/2/1 item.

I now have items saved in my database as follows:
1/1/1 (Duplicate)

This pattern continues for as many items as I create. My Kendo code is as follows:

            .Columns(columns => {        
                columns.Bound(p => p.IncrementSetID);
                columns.Bound(p => p.Increment).Width(140);
                columns.Bound(p => p.RangeHigh).Width(140);
                columns.Command(command => { command.Edit(); command.Destroy(); }).Width(200);
            .ToolBar(toolbar => toolbar.Create())
            .Editable(editable => editable.Mode(GridEditMode.InLine))
            .DataSource(dataSource => dataSource        
                .Events(events => events.Error("error_handler"))
                .Model(model => model.Id(p => p.ID))
                .Create(create => create.Action("CreateItem", "IncrementSet"))
                .Read(read => read.Action("GetIncrementSetItemsList", "IncrementSet"))
                .Update(update => update.Action("UpdateItem", "IncrementSet"))
                .Destroy(destroy => destroy.Action("EditingInline_Destroy", "Grid"))

Please let me know if there is a way to have the "Create" event only act on just the last item that I have created inline.

Hello Steven,

I believe that the problem you experienced is caused by a not updated or duplicated record IDs. By default records with ID equal to 0 (that is the default value) are considered as new (not inserted) and the Grid will continue to send to the server via create requests.

I hope this information will help.
