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

Hi,
I am having a requirement to get sum and average of selected items of a grid 

Such as in the below example I want to get the average and Sum of selected Frieght columns  

eg: https://demos.telerik.com/aspnet-mvc/grid/selection

Currently when using MVVM to instanciate a grid which contains columns with values arrays, those values arrays must be globally scoped.  All other things MVVM binds to are located within the View Model.

Please make it so that the kendo.bind method will allow for an MVVM grid to locate it's columns value arrays within the View Model. 

It would be helpful to be able to format a grids content in a more straightforward manner out-of-the-box. For instance, if a Kendo grid was displaying a typical data matrix like https://en.wikipedia.org/wiki/Triangular_matrix, it would be useful to be able to format by the upper triangular region, lower triangular region, odd rows, even rows, etc.

Add a Title tag to grid headers so that if the user mouseouvers they can see the column title/filed name if it has been clipped by the ellipsis
