Datagrid doesn't appear

[Dave]

I'm fairly new to this .NET stuff. I've got two related database tables. The
child table is just a set of textual selections for one of the columns in the
parent table - in Access it's a drop-down selector list. So, nothing too
clever.

I've set up the data connection, two data adapters and a dataset, created
the relation and filled the dataset exactly as described in
[url]http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dv_vstechart/html/vbtchnavigatingmultiplerelatedtablesinadonetdatase t.asp[/url].

Then I put a datagrid onto my form as described in
[url]http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vbcon/html/vbcondatagridoverview.asp[/url]
and set the datasource and datamember properties.

But when I run the page the datagrid does not appear at all, the page is
just blank.

Can anyone hazard a guess as to what I may have done wrong?

Hi,

Check whether Datatables are populated with data or not. thats the reason i
think your datatables are not populating correctly.

Thanks Sachin, but it wasn't that. I found the problem - I didn't realise I
had to call DataBind() in the code.

Thanks.... I had the same problem... now I know and never forget to call
datagrid.databind()
