Bug report

Reproduction of the problem

We noticed this issue on our client application. It is especially prominent on a slower network connection. We have a batch edit Grid (in cell editing). We clicked Add to create a new row, added data to it, double-clicked the Save Changes button, refreshed the page, and noticed we had 2 new entries instead of just 1 in the grid. We are currently using v2025.4.1111.

To make sure that it was not something isolated to our specific version / setup, I went to the Kendo grid demo site (https://demos.telerik.com/kendo-ui/grid/editing ) to try and reproduce. At the time of writing this ticket, the Kendo site used the latest version available, v2026.2.520.

Current behavior

The following steps reproduce the issue reliably.

1. Open the DevTools console
2. Click the Network tab and change the network throttle to be "Fast 4G"
3. Click Add in the Grid
4. Type in the cells
5. Click Save Changes several times rapidly
6. Observed multiple "Create" network calls in the DevTools Network tab
7. Refresh the page to see multiple "test567" entries in the Grid
