Sub grid batch edits lost when adding a row

[Bob]

We have a batch edit grid with a sub batch edit grid. It all works fine unless we want to add a row. When we do the sub grid edits are lost. 

Is this a bug, or not supported?

Hi Bob,

The behaviour is expected and occurs because the child grid is destroyed and re-created when its parent Grid rebinds.
Adding a new row to the parent triggers the rebind action.

As a workaround you may hook up to the dataBinding event of the parent Grid and call the saveChanges method of the child.

That's essentially what I am doing. But, as you say a "workaround", it would be nice if a hierarchical data source is used so existing child records would be re-bound as well. At least, I think that's what the hierarchical datasource give you, maybe I don't fully understand it either.

What is the recommended way to find the rows that have child grids attached to them that need to be saved? My way seems quite a bit kludgy.

Hello Bob,

You may use role selector to select all Grid elements.

$("#parentGrid")
  .find("[data-role=grid]")
  .each(function(idx, element) { console.log(element); });

But, as you say a "workaround", it would be nice if a hierarchical data source is used so existing child records would be re-bound as well. At least, I think that's what the hierarchical datasource give you, maybe I don't fully understand it either.

Thank you for the feedback, I will forward your suggestion to the team for further discussions.
