Strange behavior

[anonymous]

Hello guys,

I have a strange behaviour in my asp.net web page. My page
contains a datagrid control, which has another nested
datagrid as a user control. It works very well, when the
user expands the + button or closes it with the same
buton. However when I do this several times successively
then suddenly I got the error message:

Object reference not set to an instance of an object.
objGetDailyStoreQuantitySold.StartDate = CType(e.Item.Cells
(0).FindControl("lblInvoiceDate"), Label).Text
When I do a refresh then it sees the label control again.
I am somehow confused why this is happening. Can somebody
help?

Thanks

By looking at this code, all one could really say is that:

objGetDailyStoreQuantitySold could be Nothing.
e could be Nothing.
e.Item could be Nothing
e.Item.Cells could be Nothing
....
etc.

You'll need to show a little more code or step through with a debugger
to get more details. Know what I mean?
