Populating a data grid with a stored procudure w/parameters

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.

Hi Machelle. Try changing this
Me.cmdUYP.Parameters.Add(New
System.Data.SqlClient.SqlParameter("@web_competency_name",
System.Data.SqlDbType.NVarChar, 50).Value = "Business Acumen")

for
Me.cmdUYP.Parameters.Add("@web_competency_name",
System.Data.SqlDbType.NVarChar, 50).Value = "Business Acumen";
