Getting Server Error Syntax Error Converting The Nvarchar Value 'Sonoma' To A Column Of Data Type Int.

Hi, all

I'm getting this error at runtime when my page tries to populate a datagrid. Here's the relevant code.

First, the user selects his choice from a dropdownlist, populated with a sqldatasource control on the aspx side:<asp:SqlDataSource ID="sqlDataSourceCompany" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
SelectCommand="SELECT [PayrollCompanyID], [DisplayName] FROM [rsrc_PayrollCompany] ORDER BY [DisplayName]">
</asp:SqlDataSource>

 And the dropdown list's code:<asp:DropDownList ID="ddlPayrollCompany" runat="server" AutoPostBack="True" DataSourceID="sqlDataSourcePayrollCompany"
DataTextField="DisplayName" DataValueField="PayrollCompanyID">
</asp:DropDownList>

Then, I use the selectedindexchanged event to bind the data to the datagrid. Here's that code:

 1 Sub BindData()
2
3 Dim ds As New DataSet
4 Dim sda As SqlClient.SqlDataAdapter
5 Dim strSQL As String
6 Dim strCon As String
7
8 strSQL = "SELECT [SocialSecurityNumber], [Prefix], [FirstName], [LastName], [HireDate], [PayrollCostPercent], " & _
9 "[Phone], [BadgeNumber], [IsSupervisor], [SupervisorID], [IsUser], [IsScout] FROM [rsrc_Personnel] " & _
10 "WHERE ([PayrollCompanyID] = @PayrollCompanyID)"
11
12 strCon = "Data Source=DATASOURCE;Initial Catalog=DATABASE;User ID=USERID;Password=PASSWORD"
13
14 sda = New SqlClient.SqlDataAdapter(strSQL, strCon)
15
16 sda.SelectCommand.Parameters.Add(New SqlClient.SqlParameter("@PayrollCompanyID", Me.ddlPayrollCompany.SelectedItem.ToString()))
17
18 sda.Fill(ds, "rsrc_Personnel")
19
20 dgPersonnel.DataSource = ds.Tables("rsrc_Personnel")
21 dgPersonnel.DataBind()
22
23 End Sub
24


 

I'm assuming my problem lies in line 16 of the above code. I've tried SelectedItemIndex, SelectedItemValue too and get errors for those, as well.

What am I missing?

Thanks for anyone's help!
