Losing strong typing when using DataRow.GetChildRows()

[Jan Bannister]

This is just a general query about Data Binding.

I've got a Custom (VS 2003 generated) DataSet with a
number of strongly typed Custom DataTables within. I was
trying out using DataRelations to save me doing looping
compares in my code but I found that (obviouse in
retrospect) DataRow.GetChildRows() returns DataRow[]
which means i lose the strong typing of my rows (which i
*really* dont want to do).
Anyone come across this? Anyone any ideas about working
around it? Any future plans for the VS 2003 auto-
generated classes to provide helper functions, convertion
operators or custom dataset/row contructors that take
DataSet/Row as parameters.

Thanks in advance
Jan Bannister

Hi Jan,

What about masterRow.GetDetailRows() strongtyped method?
(Detail is detail table name)

Hey Miha,

Thanks for the heads up. I had a look for that function
and couldnt find it. I assume its put into the Custom
DataRow classes, is that right?
Do i need to have data relations in the .xsd file for VS
to auto generate the GetDetailRows() functions?

Thanks in advance
Jan

Right.

Yup. Based on relations in xsd it generates appropriate methods in dataset.
