Question

I’m trying to use a asp:SqlDataSource driven by a SQL Select with Arguments. It works as long as I don’t have any arguments. I can run the parameterized query via studio and it works and returns rows. If I any arguments, then the asp:View doesn’t render.

First, the code returns 2 rows when I execute the SQL via Studio.
Second, I don’t want it as a stored proc. Deployment issue. Smile, let it go. 🙂

<asp:DropDownList ID="lstUsers" runat="server" DataSourceID="sqlGetCSGUsersOnClaim" DataTextField="username" DataValueField="userID" />

<asp:SqlDataSource ID="sqlGetCSGUsersOnClaim" runat="server" ConnectionString="<%$ ConnectionStrings:SiteSqlServer%>" SelectCommandType="Text" SelectCommand="
SELECT aspnet_Users.UserId as userID, aspnet_users.username as username
FROM claims, aspnet_Users
WHERE claims.claimid = @ClaimID and 
(Claims.AdjusterID = aspnet_Users.UserId or Claims.SupervisorID = aspnet_Users.UserId )">
<SelectParameters>
   <asp:SessionParameter Name="ClaimID" SessionField="ClaimID" Type="Int32" DbType="Int32" />
</SelectParameters>
</asp:SqlDataSource>

If I remove the @ClaimID and SelectParameters arguments, the dropdown populates. It only fails once I add the parameter.

What am I doing wrong?

Thanks in advance,
Jason

Well it turned that if I removed the Type and DBType attributes of the SelectParameter, the code worked. sigh….

I have no idea, why though.
