Hello everybody,
I'm using some gridviews with datalists inside template columns.
Now, for each datalist I'm calling a method returning a dataset (depending
from a column from the gridview).
But I was wondering: is there a way to bring just one DataSet with two
related tables and apply the "child" table to the datalist?
I didn't find some examples of how to use DataRelations, so if anybody could
give me a hint... =/
Tnx!!! 3 4308
Data relations are used like below
dstInvoicesAndD etails.Tables.A dd(tblInvoices) ;
dstInvoicesAndD etails.Tables.A dd(tblInvoiceDe tails);
drlInvoicesAndD etails = new DataRelation("I nvoicesAndDetia ls",
tblInvoices.Col umns["invoice"], tblInvoiceDetai ls.Columns["invoice"]);
dstInvoicesAndD etails.Relation s.Add(drlInvoic esAndDetails);
It adds two DataTables to a data set, The master table, Invoices, which
just contains invoice number date, customer code etc. and invoice details
which contains the products, price, qty on the invoice along with the realted
invoice number.
then a command like
DataRow[]
drwInvoiceDetai lsSubset=tblInv oices.Rows[1].GetChilRows(dr lInvoicesAndDet ails);
would return an array of datarow objects (ie. rows) that that represent the
invoice details records for row 1 in the invoice table. The datarow array
can then be bound to a control.

Tnx for the explanation!
Would you know if is possible to apply it to, for example, a nested
gridview? (that cannot be accesed from the codebehind)

Hi,
If I understood your problem clearly, you can solve your problem like that.
For a nested gridview you can get use gridview ItemDataBound methods to bind
the inside grid. You must get the template column and cast it to a gridview
then bound it. And when you want to get inside gridview data's, first you
must get outside gridview's row's then get the templatecolumn then cast it
to gridview then you can access the inside gridview.
Have a good work,

I have two DataTables in a DataSet. I create a DataRelation between two
like-typed columns in the first and second tables, and it works exactly as
expected.
Unfortunately, the default behavior seems to be that the link (or links if
there's multiple DataRelations) are all under the left-most column. Is there
any way to put the link under the column being linked?
Thanks...

In the template column, I have put in a gridView (grid2) and a
