Custom Editor - dirty cell flag disappears

[Jon]

It is found that when using a custom editor (in my case a Kendo dropdown menu), the dirty flag sometimes disappears even though the cell and model are still considered 'dirty'.

This behavor is reproducible using your demo (http://demos.kendoui.com/web/grid/editing-custom.html). Follow the steps to view the error:

• Select a different value under Category for a row
• Select the Product Name cell in the same row (a different row will also work) to enable edit mode
• Click back to the dirty Category cell
• Click off to close cell

The dirty flag in the cell is now gone. The same behavor is happening with my implementation even though I have not saved the current grid. If you press "Cancel", the value is returned to the original.

Please advise.

Hello Jon,

The observed behavior is due to the autoSync: true configuration of the DataSource. In order to get the dirty flag to remain until the save button is clicked you should set the value to false. I.e.: 

var dataSource = new kendo.data.DataSource({
   //....
   autoSync: false
});
