I have a two level grid, child rows have a column for the foreign key (CategoryId), after a child row is added I want to set its value (it is done automatically when the parent row already exist but it doesn't if parent is new too), for example:

$(document).delegate("#MyGrid", "iggridupdatingrowadded", function (evt, ui) {
   var parentRow = $(ui.owner.element).parents("tr[data-container='true']").prev("tr");
   var parentKey = $(parentRow).data("id");
   ui.values["CategoryId"] = parseInt(parentKey);
}

The problem with this is that the value is null when it is accessed with dataview.

How to set the value for a foreign key and then see it with dataview?

BTW, I have tried this too:

$(document).delegate("#MyGrid", "iggridupdatingrowadded", function (evt, ui) {
   var parentRow = $(ui.owner.element).parents("tr[data-container='true']").prev("tr");
   var parentRowGrid = $(parentRow).closest("table");
   var parentKey = $(parentRow).data("id");
   if (parentRowId != undefined) {
      $($(parentRowGrid.context).attr("id")).igGridUpdating("setCellValue", ui.values["Id"], "CategoryId", parseInt(parentKey));
   }
}
