Error when Adding A New Record Into Hierarchical grid

Thank you for the sent screenshots and code. It really does help to figure out what the problem is.

I was unable yet to run your sent sample to run on my end. I think I will need to re-configure some lines in the code to make it work on my end. however, I suspect that the issue is happen because you are attempting to add a new record on a PZ table (table3) where the relation of this new row is not available yet (there is no parent record in the ShipDailyWorkDetail (table2) table).

This hypothesis comes from your statement that says

...btw. when i add a new row in table1 ,then table2, finally i add a new row in table3,it works fine...

Hope this helps.

hi,

I have a grid containing three-hierarchical tables, they are Ship(table1) => ShipDailyWorkDetail(table2) => PZ(table3). when i try to add a new row into table3, it throws exception. Table3 containing a WebCombo and two input area.

The scenario is :

when table1 and table2 have existed, i try to add a new row in table3

1) click on "+" sign to expend the table (according to img1)

2) click "please click here to add a new record" of table3, there isn't anything but a block of blank

(according to img2). At this time i get a javascript error (according to img3)

'RelNames' is null or not an object
uri: WebGrid_Edit.js

3) click the "blank area" again, it seems get right (according to img4)

4) fill the row and enter "shift + enter" to save then

it throws exception (according to img5)

error msg is : System.NullReferenceException:object reference not set to an instance of an object

Could you tell me why? And how to resolve it?

Thank you very much.

btw. when i add a new row in table1 ,then table2, finally i add a new row in table3,it works fine.

All pictures and code are in the attachment. I keep down almost all the code, so it maybe looks a little complex. I'm sorry for it if that incommode you.
