Bug Report
If jQuery version is set to 4.0.0, the Kendo UI TimePicker will not work initially when the format is set to "HH:mm".
Reproducible
- Go to this Progress Kendo UI Dojo.
- Add "13:30"
Current Behavior
The TimePicker will display the value "00:00". But, now try to add "13:30" and it will be added.
Note
Normal functionality is occurring when jQuery is set to 3.7.0 as demonstrated in this Progress Kendo UI Dojo.
Environment
- Kendo UI version: 2026.1.415
- jQuery version: 4.0.0
- Browser: all
1. Navigate to: https://dojo.telerik.com/@PMcDonou/UVIXEPOk
2. Enter a space in maskedtextbox
Result: space is accepted as a valid character
Expected: space should be prevented
Workaround: Use '\u2000' for promptChar instead of space
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.
- Open the DevTools console
- Click the Network tab and change the network throttle to be "Fast 4G"
- Click Add in the Grid
- Type in the cells
- Click Save Changes several times rapidly
- Observed multiple "Create" network calls in the DevTools Network tab
- Refresh the page to see multiple "test567" entries in the Grid
