Hello,
Thanks for reviewing my question. I am getting the following error when
trying to create a form using the DataForm Wizard:
"The following error occurred: Value cannot be null. Parameter name: type.
I follow the Wizard instructions by creating a new dataset, selecting the
connection and I select the table. When I click the next button I get the
error? Any ideas?

I've never done database code in C#. :(

the table. I want to filter the elements though based upon the value of a
field. The field is call CategoryType of type unsignedByte. The value I

I set the filter?
I tried several things in "Expression" but filtering still doesn't occur.

Hi, I have an asp.net 1.1 application that populates data from a

seen.
Scenario: After the page is populated, assume a change is made to the
form and the user hits update. The page then goes back, reads the
database for that record...

I built a dataform using the VB.net wizard. I have two
tables, with one relation, Parent to Child, linked on one
common key. The dataform loads the data fine, and when I
click on the Add button, it appears to add a record (the
record count goes up) but unlike single table dataforms,
the form does not automatically move to the new record.
In fact, though the record count increases by one (and
you even get an error saying the primary key...

Has anyone noticed that the VS Dataform wizard doesn't gen correctly
DISPLAYED results if you have an IDENTITY key defined for your table
(normal stuff, IMHO)? If your dataset is empty the first "Add" will display
TWO records on the resulting form. This is because they are creating a
'temporary' dataset with the changes; i.e., new record in this case, and
then they MERGE it into the existing dataset, which has a new row defined by
