populate datagrid with stored procedure w/parameter

M

Machelle Chandler

All,

I'm trying to populate a datagrid with a data adapter that uses a stored
procedure with a parameter. I get the below error when I run my code
(as seen below). Any hints?

If I delete the .value = "Business Acumen" at the end of the add
parameters statement & put the below code on a different row, the error
goes away, but I get back an empty dataset.

Me.cmdUYP.Parameters("@web_competency_name").Value = "Business Acumen"

Error Msg:
The SqlParameterCollection only accepts non-null SqlParameter type
objects, not Boolean objects.


My Code:

You have a typo in the parameter where you reference value...you declare it
as "@web_company_name" but reference it as "web_company_name", I think this
is probably the problem.

HTH,

Hi William,

Good catch - thanks. It still has the same problem, but I'm sure that
helped isolate it to one problem instead of two. Thanks!

I've run almost the exact same code and I'm ok. I don't mean to ask
something stupid, but the code is commented out as presented here...I'm
assuming that's not the case when you run this? Also, if you put a
breakpoint on the line where you set the Param value to "Business Acumen",
does it take it ok? Better yet, with the code posted below, where exactly
do you get the error, on Fill or on the DataBind?

Hi Guys,

Thanks for your help. It was 2 problems, the missing @ sign that HTH
caught (thank you!) and that I had my table name wrong in the below
statement. I took off the _dbo and now it works:

dgUYP.DataSource =
DsUYP1._dbo_prc_uyp_curriculum.DefaultView()
Click to expand...

thanks everyone!
