Hi everybody,

I've added one more parameter to my SQLDataSource (I'm using stored procedure). This new parameter is output parameter.

I'm getting this strange error

System.InvalidOperationException: String[0]: 
the Size property has an invalid size of 0. at 
System.Data.SqlClient.SqlParameter.Validate(Int32 index, Boolean isCommandProc) at System.Data.SqlClient.SqlCommand.
SetUpRPCParameters(_SqlRPC rpc, Int32 startCount, Boolean inSchema, SqlParameterCollection parameters) 

Nothing is sent to SQL Server ('m checking this info in the SQL Profiler).

Do you know what could be wrong?

Here is the definition in the Page:

<InsertParameters>
                <asp:Parameter Name ="NewPersonID" Direction ="Output" /> 
                <asp:Parameter Name="Title" />
                <asp:Parameter Name="Occupation" />
                <asp:Parameter Name="BusinessName" />
                <asp:Parameter Name="BusAdd1" />
                <asp:Parameter Name="BusAdd2" />
                <asp:Parameter Name="BusCity" />
                <asp:Parameter Name="BusState" />
                <asp:Parameter Name="BusZip" />
                <asp:Parameter Name="Pager" />
                <asp:Parameter Name="Fax" />
                <asp:Parameter Name="BusinessPhone" />
                <asp:ProfileParameter Name="SiteID" PropertyName="SiteID" Type="Int32" />
                <asp:QueryStringParameter Name="PType" QueryStringField="ptype" Type="Char" DefaultValue ="N" />
                <asp:ControlParameter ControlID="PeopleNoneForm$ddlGender" Name="Gender" PropertyName="SelectedValue" />
                <asp:Parameter Name="SpouseFN" />
                <asp:Parameter Name="SpouseLN" />
                <asp:Parameter Name="SpouseID" />
                <asp:Parameter Name="Anniversary" />
            </InsertParameters>

Do you see what could be wrong?

Thanks in advance.
