Currently if you add a row to a grid in batch edit mode any rows that have already been edited will lose their dirty flag indicator. I would like for Kendo to handle maintaining the dirty flag for these rows. If there is a performance concern with adding this functionality, then maybe there could be a setting to turn it on or off.
This has been added as a built-in functionality of the DataSource component that's tied to the Grid.
I'd like to see this more built-in to the grid. A simple client side sorting of column loses the indicators of dirty on the cells. Especially any client side operation should maintain the dirty indicator on the cell.
Dirty flags also get lost if you edit a value in a cell programatically. It's super frustrating, yet everywhere I see people posting about this issue, the Telerik folks say it's "by design" - if you reload a grid from the data source, it should maintain the dirty flags shown in the datasource, period.
We have the same problem. We need incell batch editing (autosync is disabled). After every sorting or paging the dirty indicators are gone. This is obviously a bug! The posted solution is not acceptable for several reasons. http://docs.telerik.com/kendo-ui/web/grid/how-to/Editing/preserve-the-dirty-indicator-in-incell-editing-and-client-operations
