DataList woes

P: n/a
I have a dataset that is made up of info from 2 tables. I have created a
relationship between these 2 and have added it to the dataset.

My datalist is working perfectly minus one little problem, the very last
field in my itemtemplate is an ID field from the child table. I would like
to display the Name of the company as opposed to the ID. Is there a way to
do this? I have read that there is a method called GetChildRows, but I am
unsure if this is what I need. How can I show the name instead?

Thank you, Lerp

On the itemdatabound event you should just look up the information in the
child table and plug it into the control.

It isn't clear but it sounds like you need to do one of two things. If
you're already showing the ID column, it's trivial to change to the company
name column if both columns are in the same table. If they are in two
different tables and you're already displaying the company ID from the
child, you would want to use GetParentRow.

Post some sample code or more information.

Thx guys for replying, I tried getting my sub to show the client full name
Rick, but had trouble getting the value.

I appreciate you help guys I really do.
Dale the client's full name is is the CLIENT table and I have a clientid in
the BOOKING table. My datalist is displaying fine, except I am unsure how
to get at the 'Parent Info' syntax wise.

I also thought that I might be able to easily access this data via the
datarelation but had difficulty doing that as well.
I know I am close, but here goes:

If your ID is unique, why not just do a select against your other table
instead of trying to work through the relation?
