Update Event for a calculated unbound Column in Grid

[thomasfritz]

I try to update a unbound column in the grid when a cell-value of this row has changed. I don't want to save the updated data to the datasource. I only want to show the calculated data in the unbound column.

Grid definition:

Datasource definition:

Column definition (the calculation works on data load right, but additional it should work at row update):

Thank you!

This is currently a showstopper in a project - any ideas anybody?

Hey guys - can you replicate this in Plunker for me? That way Pierre and I will have a good baseline to start from.

Here is the demo:

The unbound column should calculated then a value in the "Geburt"- or "Verlust"-Field changed. Thank you for your support!

Looks like the kendo grid is not telling your datasource that data has changed. From what I understand in the kendo doc, the grid will invoke update on the datasource when you autosync but a modified plunk (see the datasource) doesn't seem to be invoking update: http://plnkr.co/edit/17AGwScfe1VGwJz5kJUe?p=preview. I'm probably missing something, @burkeholland ?

The time is running:-(! Is there a solution to our problem? Thanks!

Sorry, but I think an answer where cool!!!!

[burkeholland]

@thomasfritz You do deserve an answer. I'm sorry.

I think the best way for you to pull this off is to tie into the save event and then refresh the grid...
