If I understand correctly, you want the user to edit data in multiple rows/cells and when they are done, they will click a Save-button. Before data is synced to back-end (or what-ever) you want to do a validity check?
There is no built-in functionality that will do this for you. But it should only be a matter of looping through the records, check for invalid values (according to your own logic) and then highlight these cells/records.
Hi,
Yes i need to check validity before sync to backend But . how to access editor context in above save event to highlight the cell and also i need all these invalid record at the top of the grid
The editor context is only available while editing. You could start editing a single cell, but not multiple.
You could get each cell and add som CSS to it, but then you would have to keep track of cell rendering.
So I think I would do the highlighting in the renderer. Styling a cell in the renderer is done in a bunch of Grid demos, like this one.
